[MOD] 720p recording ported from Hancocks ROM

BEFORE YOU READ ANY FURTHER, THIS MOD/PORT (WHATEVER) WILL PROPABLY ONLY WORK ON RED LENSED DEFYS! SORRY BUT IT SEEMS TO BE A HARDWARE THING! AND THERE ALSO MIGHT BE THE SLIGHT POSSIBILITY THAT IT IS LIMITED TO 3.4.2_145-003 VERSION ONLY! (AT LEAST THIS IS THE VERSION HANCOCKS ROM IS BASED ON AND THE SAME I TESTED IT WITH)
to make it short, i (kind of) ported the 720p recording capability of hankocks rom 1.11 to pays rom 3.3 (based on 3.4.2_145-003).
first of all, I AM NO DEVELOPER! so all props go to hankock! what i did was the following:
i took all the libs from hancocks rom which had something to do with camera & encoding (as you can see, not a very devlike procedure) and put them into my system/libs. then i took media_profiles.xml from hancocks rom and put it to my system/etc (of course i changed back permissions afterwards). first i used hancocks patched stock camera app and merged my and his build.prop so that the whole thing would run on my rom. and it worked perfectly. but this solution has 2 drawbacks:
1. hancock used 3gpp container, which is imho inferior to mp4
2. the audio encoding is very bad (amr_nb, 8kbps)
then i found out, that if i used lgcamera instead i would't need to change build.prop anymore and it still worked fine. besides of that, lgcamera is much more customizable settingwise. and by not modifying build.prop, i hope to enhance compatibility of this mod to other froyo versions.
and that is what my package contains:
-all libs with "enc", "cam", "camera" in therr names from hancocks rom (i know, i'm an amateur )
-media_profiles.xml from hancocks rom
-lgcamera 5.25 (free) btw. it works with the latest pro version from the market too
please use tenfars clockwork mod or other custom recovery to flash this update.zip. the built in original recovery won't work (doesn't accept signature). BEFORE YOU START, DON'T FORGET TO MAKE A NADROID BACKUP!!!
here you find an untouched video sample: http://forum.kut-btu.de/video/VIDEO00017.mp4
([email protected],8fps, mp4-container, video: [email protected]~10000kbit/s, audio: [email protected]/s, 44khz)
i know, seems very choppy but this is because i was walking constantly. framerate is quite good. my defy runs at 1,2ghz but i tested 720p rec @ 800mhz too and it worked the same. it might be necessary to apply sdcard read_ahead_kb patch (mine runs at 2560 kb instead of 128) to avoid slow framerate effect which could be observed on hancocks rom.
sadly, recording with .h264 codec is still not possible (and i doubt it ever will). hence the resulting video is no match for the 720p recordings of e.g. the samsung wave but imho it is still a lot better than stock and looks almost great
now i leave it to the real devs to optimize this, whatever it is.
DISCLAIMER:
I WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGES RESULTING FROM THIS MODIFICATION!
/edit:
mod works fine on the following froyo versions:
-3.4.2-117
-3.4.2-145 (as the mod comes from this version)
-3.4.2-155
mod doesn't work on:
-3.4.3-11
strange behavior detected:
after recording in 720p dmesg shows:
Timed out waiting for DSP suspend 3
pm_op()latform_pm_suspend+0x0/0x54 returns -1
PMevice C6410 failed to suspend:error -1
PM:Some devices failed to suspend

don't know, which impact this has on battery drain. after fresh reboot and w/o recording in 720p this problem doesn't show up.

Thnaks for this - i'll have a play with it later today

It works with Barebones 1.4... when im recording it seems little bit choppy, but playing it in MoboPlayer is good (smooth, maybe not 30 fps but its good!).
Thank you!

great! since Barebones 1.4 is based on CEE 3.4.2-155-002 Deblur, we can add it to the compatibility list.
yes, the recording view seems choppy on my system too, but the resulting video is quite smooth (~23-24fps).

sorry. i believe that 720p recording isn't impossible for green lense models. but i do believe that this patch based on hancocks mod will do the trick only for red lens defys. because it isn't just the color of the lens but a totally different sensor. perhaps someone figures out a mod for green lenses too.

But official Froyo is near, just wait, it should have 720p recording for EVERYONE.

I compare it to xd1 ROM files, and find the different files are,
720p_mp4venc_sn.dll64P
libOMX.TI.720P.Encoder.so
libOMX.TI.JPEG.Encoder.so
libOMX.TI.mp4.splt.Encoder.so
libOMX.TI.Video.encoder.so
Hope it can reduce the update size.

Yep it works here too but i cant see much difference between WVGA and this 720p..its almost the same. Is there any app on market that has continuous autofocus while recording video(like barcode scanner) ?

I'll create this patch for the green lens?

i don't think i will be any helpfull, cause i'm no dev. i just took the work of a dev and ported it to another rom. sorry. perhaps someone else is able to do it.

My problem with Hancocks ROM is that lgcamera records very light sound, no matter what encoding I chose (AMR_NB, AMR_WB or AAC). I am not even sure the software records sound on defy with encoding as AMR_WB and AAC.
Video works ok with MPEG4 encoding though with twp slight issues. One is video file bitrate is not the same as configured in lgcamera settings. The other one is framerate is always below 25 - not sure if SD card speed is the bottleneck.

with light sound, do you mean quiet or bad quality? strange when i set lgcamera from amr_nb to aac, it does use this codec at least the resulting video shows this in codecinfo. and i think the sound quality is slightly better too compared to amr. concerning the other two issues, i have the same experience. the framerate never goes over 23,9fps and when i force it to 25 or even 30, lgcamera won't start recording. youre right the bitrates of the resulting video are mostly lower then the bitrates chosen in lgcamera. 13 prduces ~10, 10 produces ~8 and 8 produces ~6 mbps. but imho there is a difference visible between 13 and 8mbps respectively 10 and 6 in the resulting video. at least on the computer you can see the difference.

[Q] How can I fix the HD video recording on my XT720? I'm only getting 21FPS

I stumbled across this video created by khalpowers on the XT720:
http://vodpod.com/watch/5015769-hd-recording-30-fps-xt720
This tells me that it's possible to get 30FPS out of this phone. Mine is only recording at 21fps according to Windows.
Will using one of khalpowers' ROMs fix my camcorder app?
I've tried the lgcamera app and I still get only 21FPS.
If any of you have any insight into this I would really appreciate it.

So I installed khalpowers' camera update and things seem smoother now, but I don't get 30fps. In Fraps I'm getting between 21fps and 24fps. It's better than it was before, but still not quite as smooth as I would like. The shutter lag in the camera is also better after the update.
Is this phone even capable of 30fps at 720p? The specs seem to say it can only do 24fps.

It can only do 24 FPS.

try khals video settings in lgcamerapro app. it allows for recording in 30fps.

It turns out that the FPS thing is really difficult to evaluate. This is because the phone records variable bit rate. The actual rate recorded seems to depend on how much light is hits the camera sensor (i.e. brighter scenes get higher framerates and darker scenes get lower framerates which makes sense to me).
To make things even more confusing the file contains a number as a "guesstimate" of the frame rate. This guesstimate is what most programs show. Unfortunately, the guesstimate seems to be incorrect most of the time. IIRC the only thing we found that seemed to show us the actual framerate was Windows Media Player in Windows 7.
There's a lot more about this in Dexter's stock221v13 development thread. Page 126 of that thread seems to be in the middle of it http://forum.xda-developers.com/showthread.php?t=939644&page=126 I think it started here: http://forum.xda-developers.com/showthread.php?p=11630078#post11630078 but it's really spread out.

Can someone post a link to kahl's camera update and khal's LGCamera settings. And should I apply the update if I'm running StealEpicBlue, or the ROM already has the update?
Thanks.

Even with lgcamera and khal's settings, the files are still not 30fps. Even watching his sample videos, they don't look any smoother than what I'm getting with his "fix" installed on the default camcorder app.
Anyhow, I can live with 24fps. I just wanted to know if 30fps was possible, and it seems as though it's not.
Thanks everyone for your input.
Perhaps khal can chime in and confirm that his files are indeed 30fps. IMO Fraps is a good way to verify it.

Higher rate on xt just 24fps.....that video from eclair..now can produce better than that with airplane mode ..

So............... does we have Camupdate on StealEpicBlue or not?
Thanks.

yes..complete patches included with cam update...

Identify CM7 HD Recording issue and need help to modify libcameraservice.so

This post is better to be in xt720 Dev board. But it is a pity that I don't have the privilege to post in that board now. So anybody who kindly help forward to the dev board would be great appreicated.
For quite a long time, we sufferred to HD record issue in CM7. And I spent some days inveistigaing this issue and fortunatelly got some interesting findings to share.
1. 720p HD recording fail becasue of wrong width and height parameter pass to function createOverlay in libsurfaceflinger.so.
02-13 17:38:12.030: D/TIOverlay(1876): overlay_createOverlay:IN w=768 h=432 format=99
02-13 17:38:12.030: I/Overlay(1876): v4l2_overlay_init:: w=480 h=854
02-13 17:38:12.030: I/Overlay(1876): v4l2_overlay_init:: w=768 h=432
02-13 17:38:12.030: I/Overlay(1876): v4l2_overlay_init:: w=768 h=432
Here we see, the paramter passed to createOverly is (768,432). And in comparison with 2.2 stocked Rom, the right parameter should be (1280,720) for HD recording.
2. The wrong width/height parameter is set in libcameraservice.so. Perhaps CM7 forbids HD recording...
02-13 17:38:12.030: D/CameraService(1540): Changing overlay dimensions to 768X432 for 720p recording.
And double check by open libcameraservice.so, we found the matched words in the above at the address of 0x000ae00h. The very possible guess is CM7's libcameraservice.so check width/height parameter, whenever it detect the parameters are for HD record, it reset the paramter to (768,432)!!
Proposed solution:
If someone could kindly help modify the code to comment the piece of code and build a new libcameraservice.so, we may have chance to bring HD recording back.

I forwarded into developpement thread but I don't know if it is the only problem because librairies from 2.1 to 2.2 and 2.3.

Great thanks!
libcameraservice.so is the current blocking issue I have identified. Certainly, there are possible some issues come out after we solved this one.
BTW, I've enabled 720p hardware video decoding in CM7. The phone could now play 720p video smoothly. This should be a good basie to fix HD recording issue.

Interesting. I don't have much to say about this at the moment, but for now I can point you into the source (Line 767):
https://github.com/CyanogenModXT720...ces/camera/libcameraservice/CameraService.cpp
These commits seem relevant (from the "blame" view):
https://github.com/CyanogenModXT720...mmit/a930c3c872cf6eaa57bfdddc923132cf0d48564b
https://github.com/CyanogenModXT720...mmit/cf997d0147228ece729ceb95745d20905664426d
Edit: So, it looks like to set the overlay size to whatever we want, we just change line 74 of CameraService.cpp to put the desired resolution. The other part of the puzzle is to adjust media_profiles.xml to add the HD profile. I had done that in the past by copying settings from decompiled MotoCamera, but the screen would go black and get weird or cause a reboot when the camcorder was switched to HD. I think your finding about the overlay resolution might explain why.
FYI: *Temporarily*, I don't have access to an XT720 (due to a laundry incident that took out both my second XT720 and my wife's Nexus S--so she's using my primary XT720 and I'm luddite mode until we sort out what to do about her phone--surprisingly they both may have survived--they power on, the XT720 boots all the way but no touch (when the screen is on you can see some streaking under the screen so I think possibly some residual moisture is interfering with capacitance so I'm going to let it dry some more--I tore a different XT720 into tiny pieces recently and there's a whole stack of paper-like pieces under the screen and I think they're still somewhat wet) and the NS turns on but get's stuck at the Google logo even when trying to enter recovery so I think it needs to be reloaded, I've only made it as far as fastboot mode on that one due to only having a power-only usb cable handy at the time).

what you mean by 720p playback?
i have tested with youtube videos (searched for 1080p hd
what other test can be made?
btw, hope you will be able soon to post in the devel section

Hi peshovec, I also read your reply in dev board.
As you got the same finding and have already fixed the code, could you please share the new built libcameraservice.so? I don't have CM7 source code at hand, and it will take me several days to sync. Last month, I spent near two weeks to sync CM9 code ...
And one important thing, we might need to keep libcameraswervice.so compatible with old 2.2 driver libcamera.so. libcameraservice.so from other 2.3 Rom contains a new function "_HAL_Camerainfo" ( sorry, did not remember clearly) that does not implemented in old libcamera.so. The trick I saw in the code is to "#define BOARD_USE_FROYO_LIBCAMERA".
I am quite interested to follow-up on this HD record issue with all of you help!

And for 720p playback, I mean to hardware decode some 720p video.
Xt720's CPU is able to support h264 baseline profile, but could not support H264 high profile. So I am afraid for 1080p video and H264 high profile 720p on youtube, our phone still could not play with hardware decode.
The trick to fix 720p hardware decode is to use old xt720 2.1's codec: lib\hw\*, and libOMX.TI.*. The existed libOMX.TI.720P.Decode.so in CM7 support other phones (e.g. Defy) well, but not support xt720.
I tested my phone after the fix of 720p HW decode with one 720p video, and found my phone could play the video smoothly with either Moboplayer or Moto Videoplayer. And before the fix, the playback could only use SW decode, and even overclock to 1GHz, the pictures was still lag behind of voice.

Hi Mioze7Ae, I also did investigations on media_profiles.xml and build.prop.
Acutually, stocked 2.2 xt720 Rom is not necessarily to rely on those settings in either media_profiles.xml or build.prop. As you observed, all resolution parameter was set in Camera.apk. I tested xt720 2.2 Rom without media_profiles.xml and none of related settings in build.prop, 720p HD video still work fine. And for xt711 phone, it even don't have media_profiles.xml in the official Rom.
Ah, 5 post now. Still need 5 other post ...

here is it (attachment)
also here is the mediaprofile.xml (which i use), with high and wide working
https://github.com/CyanogenModXT720...la_sholest/blob/pesh-modif/media_profiles.xml
can you try to search in youtube for 1080p hd videos and try to play some of them? i am curious if they will play on your setup (`couse in my test build i am able to play them...)

Thanks for the attachment! I will have try and give update later.
I tried to play some H264 high profile video: voice only and no pictures.
xt720's CPU fail to HW decode thoese video.
The workaround solution is to download the video, then we could choose SW decode in mediaplayer ( I used moboplayer). But the video play is very terrible, the picture play frame by frame, even though I have overclock to 1GHz.

Haha, the quick update is HD 720p recording preview work fine! Verly clearly and smoothly view from preview window!!
On the way home now, will do some more tests later.
Mark: 9 post now

Yeah, 720p HD recording is perfectly fixed!
Now we could enjoy HD recording in CM7!
BTW, I didn't tested your media_profile.xml. Now I used the one in 2.2 stocked ROM.
10 post now, heihei...
I will packed my Rom and share in Dev board tomorrow.

Great job, it's awesome and sweet.
I‘m looking forward to it!

omg, lol, so can someone confirm that hd video really work on any cm7 ? =)
well, afaik good that you have fixed preview.
Problem now in hd encoder...
Well.. we don't have it.

my fast testing doesn't seems good...
preview ok, but can't focus well (after try-ing to focus, the focus is set to the minimum distance), recording seems to start, preview display freeze. some file is generated trough.....
but that should be just my setup (is motoroi with the moto froyo able to record 1280x720p ? , if yes we can find way*)
p.s. *remark. in my opinion 1280x720 recording is just marketing, also it is not job for the phone to record at this resolution, working wide 848x480 is more than enough...

My phone is able to HD recorde in 2.1 and and 2.2 Rom, but lose this ablity when upgrade to CM7 2.3 Rom.
Not sure whether our phone have some HW difference.

I am uploading my Rom to DEV board.
Have a try.

[MOD] 2.3.6/7 Video Recording audio improvement -- WIP

Hi everyone
when you record a video on your original SGS 4G camera, your audio sampling is :
66 kbps bit rate.
16 KHz sample rate.
which is pretty lame...
If you ever tried to record live shows or concerts, you probably noticed audio is awful on recorded video...
Introducing Video Recording audio improvement MOD
found and very well explained by rafalense (http://forum.xda-developers.com/showpost.php?p=10980448&postcount=268).
Performed on SGS 4G camera by me. So, now recorded audio sampling is :
118 kbps bit rate.
32 KHz sample rate.
file size change is barely noticed.
Still camera is not modified.
I took, as a basis, the Team Acid modified camera - done by DSexton702.
So it is capable of taking pictures when battery is low and also by using the power button.
This is still in beta as :
1. Currently Audio-Video is out of sync. I need to check if this can be fixed by changing Video sampling rate....
In the meanwhile, you can fix this on PC very easily.
2. This mod does not use the media profile xml for greater video frame rate.
I actually put the original file back. I found the result to be not supported by all players and having some side effects like visual waves (and much larger file size).
3. Actually I examined DSexton702 media profile and it defines some various audio sample rates but always create 16KHz at the end.
If someone here has the knowledge in A/V synchronization or a good setup that works - please let me know so i will fix it.
Thanks.
CWM Flashable files to download (Camcorder mod and original camcorder to revert back) :

You can use this to sync A/V - http://fixounet.free.fr/avidemux/download.html

Awesome work! Thanks.

Glad to have u aboard thanks for this man this is well needed!!!!!

Now having AntonX kernel supporting Vodoo Sound - I will test audio HiFi record option enabled on video recording and update.

Would love to see this become final. You certainly are right about the audio during concert recording. All we hear is pure bass... Thank you for working on a much needed video recording mod.

Thanks for the work, itzik2sh.

Edit : guys working with Voodoo sound (with supporting kernel)
need to run the Voodoo sound app and choose 'Recording Preset' - then change default to 'Loud environment - with DRC'
This should improve the recording level of loud shows.

Hi
Did anyone here test this MOD with live concert recording ?
If it doesn't help than I'll drop all further work.
I thought this problem is SGS 4G unique, but it turns out it exists on all Sammy phones,
even Nexus and SGS 2. See this bounty thread for SGS 2 :
http://forum.xda-developers.com/showthread.php?t=1172048
and this :
http://forum.xda-developers.com/showthread.php?t=896826
I'll try to ask AntonX to take a look or maybe ask supercurio on kernel implementation...
I also tried installing LGCamera from the market, which supposingly has an audio gain control, but it fails to launch and I had to uninstall it.

Nice improvement

After voodoo digital recording, video and audio are repacked and converted to the device analog sampling rates, that this tweak changes (but also unsyncs)...
So if you have the time and effort, I'd appreciate if you share your experience with us all.

Very Bad audio quality in video recording

Hello guys First of all it's my first post in the nexus 5 group (i've did a pre-search) and i contact you with this problem
Last night i went out with friends at a pool party and used my nexus 5 for recording some videos from the stage. The music wasn't to loud, just like normal club music, in open space. Today when i took a look on the video i got scared...the sound quality is insanely BAD !. It's like the phone is set to +100 gain in the microphone... I tried normalizing audio in premier pro but with no chance. So i ask you guys, do you know any solution on how i can repair the problem. The best audio quality i had in recording videos in club (audio especially) was with my Nokia E51 that had the best mics i can find one a phone...
so here is a comparison:
In club music (closed space) shot with my Htc One S (no dual mic or things like that) -> https://www.facebook.com/photo.php?v=487777791348118&set=vb.100003477036350&type=3&theater
in club music (closed space) shot with my Nokia E51 (a 5-6 years phone that still records audio crispy clear for a phone ! - don't look at video quality) -> https://www.facebook.com/photo.php?v=247706518688581&set=vb.100003477036350&type=3&theater
last night with my nexus 5 ->https://www.dropbox.com/s/3vtisokit5ontwl/VID_20140727_032412.mp4
All the link are so you guys can see that exact problem that i have. I want to repair it, if it is possible in the stock rom (with a app) or if i need to install a custom rom, what is the best rom that resolves my problem and has best performance .
Thank you in advance !

I have exactly the same problem. Tried recording at a couple of indoor parties(so a little louder than your situation. Couldn't recognize any music when playing the video's afterwards. Terrible quality
Sent from my Nexus 5 using XDA Premium 4 mobile app

Partial fix - i think
Ok so last night i got an app from play store called microphone that has a setting on the mic called mic gain. it was set to +32 dB....overgain ! so i set it to 0 and did some recording in the house with my audio system on a high volume and afterwards put the phone next to the speaker and seem that it records decent . but i think it is a problem related to software settings... will keep you updated on what i found

Sounds awesome. Thanks for your effords
Sent from my Nexus 5 using XDA Premium 4 mobile app

Problem solved?
I can't post links so if anyone wanna fix this or just post the links from my post that would be great, thank you.
So I've found a solution, or at least a temporary one
Get the camera app called Lgcamera. In this app you can manually set your audio settings.
Set it to AAC and set the stereo option to On (this did it for me atleast).

I made a little video about it since I couldn't find this solution before, hope it helps!

Please help spread the video on forums where this issue is discussed so more people (and perhaps even Google?) can record without that awful noise reduction/cancellation! If enough people complain then they will probably (hopefully) implement these settings in the "Google Camera" app!

Thanks for the video! This is the video.

BE CAREFULL though with LGCamera, because I found that no matter what you choose in settings, fullHD (1024p) videos are ALWAYS recorded with 15 frames per second only (vs 30 as normal), making the videos look very choppy. So I deinstalled LGCamera again. Otherwise great app.
But I found a good substitute, it called Open Camera, link to the (free) app and also a possible video mic fix (reduces mic gain).

Hmm, strange. I do not have that problem. I record with 30FPS without any problems. Maybe something is wrong in the settings? Have you tried changing the video format around? The app is not that great but it does the job for now, atleast for me.
Edit:
I noticed that the front camera is not that great in Lgcamera, but the back I have no problems with. I recorded a video on my instagram if anyone wanna check it out. I'm still changing the bit values around hoping it will sound even better.
Speakers are "semi-loud" and i recommend watching the video in your phone or atleast lowering the bass if you're watching it with "real speakers".

Here are my settings for this particular video:
Back camera
1920x1080
H.264
Vid Bitrate 17mbit
Vid framerate 30
AAC
44100 Samplerate
128000 Bitrate (unsure of what value is best here)
Stereo OFF

Ok thanks, I might give it another try... Open Camera works well for me, though.
Did you check the actual framerate of your resulting video with a tool like mediainfo or VLC Player codec Info?
Nice guitar work btw

Open Camera works too, but I still get the audio artifacts when recording with a backing track. I get those in LG too, just not as much. Lg is in no way perfect, but the sample and bit rate allows a bit more customization if you ask me.
I'll upload one with OC when I get home! And thanks
By the way, what settings did you use in Open Camera? Or did you just lower the gain?

higher bitrate = better quality/higher filesize :good:

HUUUGE discovery today!
Update your LG-camera, go to settings and set audio to "voice communication" = headset. You can now record with your headset, see my instagram @Callemusicman for results!
It completely removes the noise cancellation!!

Isn't there any other solution? Because if i use, for example, Instagram, the sound is still very bad... so this LG app isn't usefull for recording with Instagram or other apps...
