[Q] Can Nexus S play smoothly 720p video? - Nexus S Q&A, Help & Troubleshooting

There are plenty of posts on the net discussing whether Nexus S is able to record 720p however nobody is talking about whether Nexus S actually _can_ play 720p And when I tried it, it didn't went well.
I downloaded some 720p trailer (mov format), transcoded it using Handbrake to mp4 (I used some iPod/iPhone profile, I just set the resulution and quality to be preserved) and I copied both of them to my Nexus S.
Default video player can play only the mp4 file and the picture is very choppy. MoboPlayer can play both of them, but the mov file only in "soft decoding" mode. Funny is that the mov file is _much_ smoother than the mp4 file, it's not perfect but it looks almost as good as on my pc.
What am I doing wrong? I thought there should be some kind of hw acceleration for mp4 files...
Later I downloaded some 720p trailer directly in mp4 and it played well and very smooth. But the bitrate was just about 2500 kbps whereas the bitrate of the mp4 I was talking about before was about 6500 kbps... which I guess is the reason why it played so choppy. So 6500 kbps is too much and my Nexus S just can't play video in that quality?
And the last thing, the mov file uses the same codec as mp4 file (h264) so why the default player can play only mp4 files?

Viewsonic 720p MKV File Lags While Playing

Hello Guys,
I have used both Vegant and Latest TNT 2.2 and both lag while I play 720P .mp4 encoded videos downloaded from youTube, I'd like to know if its a software or hardware limitation? Does anyone else have the same problem with 720 .mp4 files from youtube? Does it lag (as in audio and video lose sync - audio plays faster than video).
ive incoded some 1080p bluerays using handbrake normal preset H.264. container mp4 also had to do this with 1080p .mkv files couldn't even get them to play otherwise. after that they played great on my tablet
The Tegra 2 chipset cannot handle h264 encoded as high profile. Main profile works fine. I know this confuses some people, but grab the excellent "mediainfo" tool (http://mediainfo.sourceforge.net/en) and you can see how your file is encoded.
MP4 containers seem to work best, although I believe Rockplayer can play MKV's with hardware acceleration.

What software do you use to play 1080p mp4 movies?

I tried RockPlayer Lite and some other players in the market but none work.
Please help.
vitalplayer?
Try doubletwist. Plays mp4

It's not really just a question of what player - it's a question of what 1080p mp4 files too. Tegra 2 is extremely limited in what it will play back in a 1080p mp4 so how the mp4 is encoded matters as well. I think I read somewhere that it's baseline profile only...and that's with hardware acceleration. Software only, I'm guessing that no file of that size will play - it's too many pixels to push around.
And Rockplayer is my mp4 player of choice (to the extent I actually registered for it to get rid of the ads and the R). In hardware mode, it doesn't bat an eye at my 720p mp4s in main profile.

x2. If the 1080p video is encoded the right way, even the vanilla player will play it.
I've been using h263 1080p / 720p MP4's and they work well. Even some MKV's will work with the vanilla player, if encoded a certain way.

Any luck getting h264 1080p to play? Any specific software you recommend to convert files to appropriate encoding?
I've had success in the past doing it and watching 1080p .mov movie trailers but haven't done so since I've upgraded to TnTLite 5.0. I would recommend Handbrake for encoding and then playing with it. From using Mediainfo on them, I think they were Level 4.1 main profile with 2 reference frames, no Cabac.
I found this on fudzilla from google (I can provide a link if needed)
First of them is H.264 with sub standards Baseline Profile (B frames) — 1080p/20Mbps, Main Profile (B Frames, CAVLC) — 1080p, Main Profile (B Frames, CABAC, no weighted prediction) — 720p/6Mbps and High Profile (B Frames, CABAC, no weighted prediction).
Tegra 2 also supports High Profile (B Frames, CABAC, no weighted prediction), MPEG-4 (Simple, B frames and ASP Profiles) — 1080p/8Mbps, H.263 (Profile 0) — 720×576/4Mbps, DiVX (DiVX 4/5) — 1080p/8Mbps, XviD (XviD Home Theater) — 1080p/8Mbps, MPEG-2 (Main Profile @ Main Level) — 720×576/10Mbps, VP6 (simple and advanced profile) — 720p30/2Mbps, Sorenson (simple and advanced profile) — 720×576/4Mbps, JPEG up to 80 Mpixel per second.

Caveat - 1080p encoding is slow and the files are big. Unless you are doing 1080p encoding for some other purpose, I wouldn't do it just to play on the G-Tab. It really seems to be stretching the limits of the technology. I prefer to do a really good quality 720p encode instead. They look equally good on the G-Tab at a smaller file size - and on a 60" plasma I still can't tell that they're worse. I had floated my encode parameters for handbrake somewhere back in this section.
vitalplayer, vanilla player? What is better, what supports more formats and it is more convenient?

The only luck I've had with hardware accelerated video (the high-def stuff) is Rockplayer or vanilla player. Don't like the lack of file browsing you get with the vanilla player. You can get around that by using a file explorer to open your videos instead of the gallery.
I have a couple of mkvs that Rockplayer won't play (SD ones at that), so maybe an experiment is in order!

Playing 1080p MKVs over HDMI

How well does this operate on the sensation? How smooth is the playback of 1080p MKVs? Also, can I play this on rockplayer for example or diceplayer and connect it up to my TV and watch it over HDMI?
Thanks.
Really? No-one?

Well I'm not sure if you know this but there are currently no accessories for MHL that can be utilized in the Sensation. Therefore, it can't be connected to a TV yet which explains why nobody is answering your question. Wait for the MHL dongle to come out and I'm sure people will start saying something.
trying to play 720p mkv just on the phone and its dropping alot of frames.
Tried QQ player and rockplayer but still not enough power to decode the movie in software.
May have to convert the file to mp4 to allow the hardware acceleration!
will try over the weekend and let you know
As of yet, nothing can play MKV's properly I don't think even the SGS II can.

It can. I've just played a 720p MKV and it handled skipping, pausing etc like any other .avi file.
Sorry. Didn't read the title. OP was asking about 1080p. Not sure if I have any 1080p things to play.

I'll test this and get back to you later. I'm sure I've got a 1080p mkv somewhere on my PC.
I'm pretty sure the Sensation's software isn't optimized. I think when we see some custom ROMs (e.g. Android Revolution by mike1986) we may be able to play MKV's
I can play 720p and 1080p mp4 (h.264 High Profile at any bitrate + AAC) videos without any stuttering, using hardware acceleration.
MoboPlayer and DicePlayer can play 720p and 1080p MKV but with some little stuttering.

Just tried moboplayer with my 720p test MKV file and it does play alot better than rock player but still not at full speed.
This may be due to the bitrate of my MKV file though (5500kbps)
EDIT:
Tried the trial of diceplayer and it plays my 720p MKV file perfectly

Thanks a lot for testing that out, much appreciated. A lot more useful than the guesstimates made by others in this thread.
My Sensation was unable to play a 720P 60fps H.264 8 Mbit MP4 perfectly smoothly in the stock Movies application. Playback on the SGS2 was noticeably smoother, even from a USB key. I will try it with Diceplayer... VPlayer was even worse though.
EDIT: Seems to playback reasonably well in Diceplayer, and perhaps a little bit smoother in Rockplayer. This could all be placebo though!

your test file is mp4. so rock or stock or any other player works same way.
(using embedded media player module)
if you test MKV/H.264-High/DTS or Flac encoded files, you can find differences.
MKV is just a container for MPEG-4 in most cases. I don't see your point.

point is mkv container is not recognised by the sensation default video player, so although the video stream should be played back via hardware decoding it is not.
Most other players that do recognise .mkv files use software decoding, which is fine for AVI (DivX/XviD) or low bitrate h264 files, but at higher bitrates the frames start droping.
Diceplayer is good because after it splits the MKV audio/video streams it recognises that the h264 video stream can be decoded via hardware, this allows much higher bitrates to be played smoother and should consume less battery as the cpu is not thrashing its nuts off.
It may be that in a future software update MKV are supported by the default player, as it is on the SGS2
I wonder if Android Revolution HD or CyanogenMod could play 1080p MKV with Diceplayer or similar, on the Sensation. Would be utterly fantastic if they could!
I'd like to see playback on an OC'd sensation/gs2

[Q] Medium bit-rate HD h264 playback

Hey folks, I was trying to watch a video on my TF101 that I made with my Galaxy S II today, it's a 1920x1080 17Mbit/sec h264 video file. MX player won't play it in hardware. Any way to fix that?
Try Dice Player with the tegra plugin.
Freemake Video Convertor
Easiest converter I've used....take your 1080p file select 720p mkv or what ever other extension and press convert. Might look into the audio settings a bit more tho. (I haven't yet) but the audio comes out not as loud...
Then use MX video...with HW video and SW audio.
Also this might save you time if you try the converter...don't use the Android setting...didn't work for me...wasted 4 hours (slow laptop).
Swyped using my Pinky
I really didn't want to have to transcode the video.
Diceplayer didn't work, even with the plugin. It was a stuttery, frame dropping mess. At least in MX, it plays in super slow motion.
For me, BS Player seems to be the best for playing HD mkv files.
It's not an MKV file. It's h264 in an MP4 container recorded by my Galaxy S II phone.
Did you try playing it in S/W mode? I've had to use it for 1280x720 videos on my TF101 and Captivate with MX.

Argh, sorry. I really suck at multitasking.
I was just transfering a mkv file over to my Transformer when I wrote that comment. lol
What I meant to say was that BS Player seems best for me to play HD movies (with big file size).

[Q] Video Convert configurations

Guys I have HTC sensation,
Can any one tell me the configurations to convert the video to play on my phone..
like wise,
video size
bitrate
frame rate
aspect ratio
etc
video codec
I use imToo video converter..
I need HD video..
everytime i convert I see quality is gone worse..
Help././
Just use some more advanced media player, like MX Video Player. Streams mkv, mp4 and avi seamlessly over upnp - So ill guess it plays most others as well.
I'm using DicePlayer. It plays everything so far.
Either use MoboPlayer

Or convert your videos to be 960x540
