24 bit output? - MTCD Android Head Units Q&A

I have the PX6 Max 10 and I use Poweramp. My FLAC files are 24 bit (which Poweramp recognizes) but the ultimate output ends up being 16 bit. Can this unit output 24 bit? I can’t seem to find the proper setting.

Bets video performance and quality.

Diamond users! Frst I wanted to make a long research thread about the possibilities of video conversion and optimals formats. Instead I'm just gonna tell you which programs work and which video formats are best for my diamond 2 (freshly flashed!)
Use FormatFactory for conversion (google it, it's free!)
You can convert any filefrom any place (iso's and DVD's included) to any other format and setting you want. Good thing is that it's very user friendly and easy to use, and you can insert your own options. Convert any videofile by selecting it, use the options to set it's framarate, screensize and codec, and convert it.
Use Coreplayer 1.2.5 build 4506 (it's the only one that works on my diamond 2, and it's not free)
Or WMPlayer (comes with the phone, but less options and compatibility with file formats)
Here's some pointers on conversion settings without much quality loss.
-In FormatFactory use the "convert to mp4" option. Select any file you want (also from dvd, which gives you some neat options like inserting subtitles and choosing audio language). I've tested mp4 divx and mp4 xvid codecs, as well as AVI and WMV. The last two are bigger in size, and the AVI files run veeeery slow on your phone in coreplayer. WMPlayer doesn't support AVI. I haven't tried MPG conversion, because it is usualy larger in filesize, and the MP4 encoding worked a charm for me, good quality, 18 to 21 frames (human eye can see 21 tops) and small filesize.
-Under settings, you can do whatever you want, just be sure to change the screen size (you can type your desired size) to 800x480, which is widescreen for diamond 2 (largest)
Choose the Xvid Encoder (Divx lags more and is a bit larger. tested on 20 meg DVD rip files, divx came out 13,5 megs in size while Xvid came out 11,2 megs. for any type and size of video the difference in size after conversion is up to 20%!) The H.264 encoder sucks, because coreplayer won't be able to play it smoothly (almost not at all!).
-You can choose to alter the bitrate settings for either video or audio, but I suggest you shrink em down, since my tests resulted in no recognizable loss of quality for extremely different settings. I had a hi-res file with 1600 bitrate and 24 frames p/s, and a lo-res file running only 786 bitrate and 20 frames p/s. No noticeable difference for me, and the size and running of the file was way better than the higher one. My optimal settings thus are:
-800x480 (Resolution)
-786 (Bitrate)
-20 (frames per second)
For audio I didn't change anything, since it is already set quite low, except for the bitrate, which you could preferably set to 22050 if you want to save a small amount of megs on your storage for a full movie. but 44100 and 48000 are fine too, doesn't differ much in quality audio anyway.
Now all you have to to is press okay in the options screen, and "start" on the mainscreen where the videofile has now appeared, ready to be converted. you might wanna set an output directory for your videofile, but that speaks for itself....
Tell me what you think of the settings and program, and tell me if you found any other (better) settings for running video on diamond 2.
Good luck!

download SUPER !
it's really super
Converst superfast to any device...
then watch with CorePlayer !
I got about 30 hours ov video in superb quality on my phone for my little boy
you know the complete disney / pixar stack opf video's
I copnverted everything with SUPER
hello flexikon,
800x480 fits pretty strange on WMPlayer (i keep the phone on the side not straight up) tbh 480x272 fits better on the screen but looks worst - what would be a good resolution to use for WMPlayer ??
or should i select 16.9 convertion for 800x480 ??
thx
I've seen other discussions about this. It's probably the landscaping that screws up your resoltution. since i have no direct link to other topics and the google search for the forums is out, you gonna have to locate the topic yourself, but it's about mp4 encoding and it makes this thread pretty much useless, since better options are available through there....

Fast video playback - SD videos

Hey all;
So, I've had my Eee Pad for a few months now. Absolutely love it. One of the things that I'm aiming to do, is movie playback for road trips. Myself or my wife (whoever is passenger) can watch a movie, while streaming the audio through the car via Bluetooth (FordSync).
I had converted a couple of movies from HD MKVs (720p and 1080p) to MP4 for playback on my tablet using Handbrake and they played fine. Even HD (720p) music videos I've ripped from YouTube playback OK once converted, however any of my 420p (DVD) rips don't want to playback properly. The video is 2-4 times faster than it should be. I've Googled, and even done some searching on these forums, but the threads regarding fast video playback didn't apply to the Eee Pad.
I'm still on stock ROM, but updated to the latest one (3.1 I think it is). I've tried the built in video player, as well as a couple of others (current one installed is mVideoPlayer).
My Handbrake settings are as follows:
Picture
Keep Aspect Ratio
Anamorphic: None
Modulus: 16
Video Filters
All off
Video
Video Coded: H.264 (x264)
Framerate (FPS): Same as source
(Video)Quality
Avg Bitrate (kbps): 2200
Audio
Audio Coded: AAC (faac)
Mixdown: Stereo
Sample Rate: Auto
Bitrate: 160
DRC: 0.0
Advanced
Encoding
Reference Frames: 1
Maximum B-Frames: 0
Analysis
Motion Estimation Method: Uneven Multi-Hexagon
Subpixel ME & Mode Decision: 6: RD in I/P-frames
Motion Estimation Range: Default (16)
If the video has a 1080 resolution, I usually bring it down to 720 as it plays back better. If its an SD film, I leave the resolution/aspect ratio to whatever the video is encoded as.
Any help is greatly appreciated!!
Some things to try:
Go here build.handbrake.fr and download the latest SVN Handbrake GUI (Not CLI) and install it. It's possible that it is a bug in the latest official version that has been fixed.
Second, rather than using your own settings which may have inadvertently switched some switch - use the High Profile preset and encode this way. It should be automatic, but use Constant Quality = 20 instead of average bit rate as well. These are settings that are known working on mine and other devices.
Try that and report back.

How are you ripping the DVDs? If you're just re-converting the .VOB files, that might be the cause depending on if Handbrake can properly read the d2v info embed in VOB files and properly inverse-telecine the DVDs. This will explain why seems to play 2x faster as the timecode is not read properly by handbrake.

I did 4 movies, one I ripped myself, the other 3 I've had for years which I downloaded. Aside from some granyness in the videos now (I'm going to re-try with the 2-pass encode) they played perfectly. Thank you!!

Once I ripped the movie using AnyDVD, I'd throw it in to Handbrake and use the HighProfile setting. I'd set the aspect ratio to be the same as that of the movie, 2-pass encode with a turbo first pass, set the audio to be the 5.1 track as passthrough, no chapters, and the rest of the settings as the default for the profile. The original ripped videos play fine on my PC, and even the re-encoded ones played fine as well.

[Q] Walkman app HR?

I just added an album in flac format on my z3. and if i look in walkman there is a HR behind the album and behind some songs. What does this mean? I thought it stands for high ress audio or something.
Yes it does. AFAIK it means either the bit rate is above 16 or the sampling rate is above 48kHz.
rwesten,
It means the file you're playing is not only a FLAC, but a Hi-Res FLAC. It's like this:
You got your lossy files......mp3s, AACs, which are at the lower end of music quality (but take up the least space b/c they're the most compressed). Then you got CD-Quality files and Hi-Res tracks, usually in the FLAC format (or related like ALAC). Lower quality FLAC tracks are CD-Quality. They are better than mp3s, but not AS good as Hi-Res FLACS. They are rated at 16-bit/44.1KHz (sometimes 24-bit, but not often). THEN you got your Hi-Res FLAC tracks. Like the CD-Quality FLACs, Hi-Res FLACs are lossless, which means NO data is lost or taken out (think blu-ray vs DVD). These are rated at 24-bit/96KHz, though they are definitely known to go as high as 192KHz (and in some very rare cases, up to the 300-400KHz category).
All the FLAC files are compressed, but somehow they still retain all the original music data information. They do have uncompressed lossless files like WAV files, but they take up more room, so I think FLACs are better b/c they take up less room (compressed) but still have the same sound quality (lossless). If you are a TV guy, then think of mp3s as 480p, CD-Quality FLACs as 720p, Hi-Res FLACs as 24-bit/96KHz as 1080p, and like 24-bit/192KHz+ as 4K. lol The Z3's built-in DAC (digital audio converter) can play Hi-Res but only up to 24-bit/96KHz, which is still amazing and better than most other phones. If you want higher, you can buy a separate DAC and hook it up b/t the phone and your headphones or speakers. My thinking is down the road, the DACs will get better, so you can wait and buy them later, or get them now. Maybe they will get cheaper over time, so maybe just stick with 24/96 for now.
"HR" DOES in fact mean Hi-Res. It means you're playing the highest quality of music that's available today. I just started getting into all that recently and have learned a lot in only 4-5 weeks (as you can see above). lol Some say it's all BS, but I've compared songs I have on mp3 to Hi-Res FLACs like 24-bit/96KHz, and I definitely DO notice a difference. Hi-Res doesn't sound so "closed in"........ you can hear each instrument distinctly where on the mp3 version it sounds like more condensed, or like you're listening through a small hole in the wall. lol I compared my mp3 of "Babe I'm Gonna Leave You" by Led Zeppelin and then the Hi-Res FLAC version I got from www.hdtracks.com, and yeah, the HR version sounded bigger, better, more clearer, louder at the same volume....... I could hear little guitar fills much more clearly on the FLAC version too. So if you want more, go there. Not many options right now, but that's a great one with an ever growing library. Or to Pono Music (Neil Young's push for Hi-Res), though you can only look up what they have for now. The music will be available for download in the next couple months I read somewhere.
Hope that helped!

[Q] Choppy Bluetooth Streaming...

Hi guys,
I am new to this blog. Basically I am working as a Infotainment system tester over Bluetooth profile. I am encountering lots of choppy music while Bluetooth music streaming on infotainment systems via android devices. While taking Bluetooth traces via Frontline BPA 600 sniffer, I am able to get A2DP profile with SBC frames where Bitpool is 35 and Bit rate is 327 for all the frames however just CRC changes with its after check values. Can you please suggest me where exactly the problem can lie, i mean like what parameters can be changed, Bitrate, or Bit pool or buffer, while decoding the music packets?

Getting USB Audio Support for external DACs

Hi -
I know that Android these days has relatively decent USB audio support, when connecting an external DAC.
On the Google Pixel I'm connecting a Fiio Q1 external DAC and sometimes it skips in songs, as if it's a scratched CD, when playing through Spotify. I know there is an app (USB Audio Player Pro) which will provide proper support for playing audio through an external DAC, but only if you use that app as the player. So will not work when streaming from services such as Spotify.
I believe this is mainly due to sample rate conversion, which apparently Android does by default, instead of matching the actual sample rate (e.g. 44.1 KHz CD quality will get upsampled to 48 KHz, an unnecessary step).
Is there a way to get better support, perhaps through modding the stock ROM, or installing a custom ROM? Is this a kernel issue? Or a ROM issue?
Thanks.
飞奥?
About the Android sample rate conversion I think there's no solution for now, just let Google do their job.
By the way, I'm using HTC type-c to 3.5 jack cable, it has a DAC, works fine here, no "scratches".
