why video is so lagging - Nexus S Q&A, Help & Troubleshooting

hi there,
I just try to put my iphone4 video clip to test my new nexus s.... it is so disappointed which the performance is so lagged.
Video encoded in:
Format: H.264 (1280*720)
Bitrate: 3000 Kbps
Audio: HE-AAC or Mp3 still the same
My player is: RockPlayer or Vplayer (both latest version)
Is there any tweak? or I need to re-encode other format?

same problem here. i think its a hardware limitation issue with nexus s.

the nexus s is missing graphics aceleration. wait for that update and it should be all better.

No audio in video mp4 video format

I am able to play this particular video file, but am not getting any audio. Is there a certain audio codec that I need to download?
File details: Video: MPEG4 Video (H264) 1264x528 23.98fps [Video]
Audio: AAC 48000Hz 6ch 4608Kbps [Audio]

It is because Galaxy S can't playback audio with 6 channels , i did not try this my self but that is what others observed.
Yes, I think it's limited to 5.1 channel audio encoded videos.
Also, that 4608kbps audio rate is awfully high.
Try using rockplayer and see if it works.
Was having a hard time w a video, wouldn't work in act1 nor the stock video player, worked great on rockplayer
Free on android market
Keep in mind Rockplayer is purely software player , it will not take advantage of phones Hardware acceleration , it will not play high resolution with good bitrate without dropping frames like crazy.
It would be better just to recode audio track.
I was just curious, because this was the same file that I had on my SD card that was in my BB Bold, which was able to play it???

[Q] Can Nexus S play smoothly 720p video?

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?

Full HW video decoder : BSPlayer is THE player!

Hi,
BSPlayer realease his software for Android.
Pro :
Real HW decoder for most formats (even 1080 files)
Gallery - like browing, including panorama
Video playlist
Timer to shutdown the player...
Cons
Doenst support Dock media's key (play/pause)
For seeking, you must use the slider, if not, it revert to begining
PS : I have mobo player and mx player, even files thoses to last cant play, BSplayer play them smooooooothly
You have to download also the ARMv7 plugin
Have a try, it's free (ads)

Posted aggain? Oh, well.
Still... Nothing can play 1080p :'( !!
Really disappointed !! Galaxy S II and Galaxy Note both can play 1080p but transformer doesn't...
It's supporting Videplayback over SMB. Sry Diceplacer but this is a must have for me.

I disagree. All of my movies are ripped straight from Blu-ray and are 1080p and play via MX player or Dice Player.
The best video player is stock. The smoothness cannot be beat by any 3rd party video player. I've tried MX and Dice and they are only as good or worse than the stock player. The only reason to use a 3rd party video app is if you want the extra UI features or if you are unwilling to transcode/remux MKV to MP4.
Anyone who tells you that DicePlayer/MX Video/BS Player can play any 720p MKV they throw at it is probably watching some pirated movie with crappy warez scene encode settings. I have quite a few 720p MKV/MP4 movies that are unwatchable using the stock player because they stutter so much. The revered DicePlayer is even worse than stock with these movies, and so is MX and BS.
Don't get your hopes up.

I am tired of hearing people imply that MX Video Player or DicePlayer are responsible for successful playback of their movies. If your files are MP4 (which can easily be converted from MKV using VidsOpt), they will play as good and usually better with the STOCK PLAYER.
Also, what encode settings did you use and what is the average bitrate of the movie? I doubt the encode is transparent. It'd be interesting to see a source>encode screenshot comparison.
it doesnt even start to play .mkv so its worthless. Sure would be nice to have a great mkv player.

Despite what your tired of hearing MX Player plays videos better than the stock player IMO but that's just me. That's what's nice about visiting the market is that you can find apps that are better and better than the last including stock for all facets of the tablet. Just like IMO ADWLauncher EX is better than the stock launcher. It's just the order of things and how they work. If you prefer stock player over all others than by all means. Everybody has what's good for them and you go with it.
I don't understand. First you say that the stock video player is the best;

You make no sense here.
The stock video player has terrible codec support. For a high-powered device like the TF101, I shouldn't have to transcode my files to a very specific format just to get the stock player to play them.
Personally, I use VLC. A pre-alpha version was released a couple of months back, and it's great. It plays every video file I've thrown at it and doesn't stutter at all.
Can you link the apk for the VLC you're using? I found a "noneon" build of it on this site, and the playback is absolutely horrendous. It is far, far worse than the stock player. Is this the same compile you are using? These are the specs of the video I used:

really? That's the same build I'm using and I'm finding it perfectly fine. Weird.
Thanks for the heads up on BS player. Indeed it is playing most of the 720p content off my server without issues, I say just above Dice Player and what makes it better than Dice is it is FREE. The interface is fugly like some highschool kid with crayons but who cares as long as the decoding engine works. For some reason MX player never plays anything off my network but plays local content good, strange.
Got rid of Dice, will probably delete Mobo player and rock as well, too many players . . . .

Don't sweat it, he's just trolling because it's better than what he's getting and he uses the stock player which is sub-par to MX or Dice players. So far I've seen what his settings are and mine are better so he feels he has to troll. Go home troll.

Your encode settings suck, that's why you aren't experiencing the issues that I am. I care about transparency, and you, for whatever reason, obviously do not. You could really tell you knew what you were doing when you called your 1080x800 encode 1080p. 1080p is at least 1920x800...you are missing several hundred lines of resolution. Please, post some source vs encode screenshots. You can do this with VLC Media Player by pressing Ctrl-Alt-S.

Evidently you don't have your game on when it comes to getting your settings correct since you seem to be having issues and I don't. You're trying to make your TF perform beyond it's specifications. As I said before those were my old settings and as I now use DVD Catalyst with higher bitrates that I have even higher quality videos as I did before. If you would stop hating for a moment and actually read the posts that people place maybe you would learn something.
Sometimes the best thing to do is go back to what works and make your way from there. HERE is a post that has a guide that should get you to making decent videos for the TF.
Good luck.
I know that I am pushing the limits of the TF, but this is so I can achieve transparency of my encode to the source. We are approaching this from two different directions. I am more concerned about transparency and you are more concerned about being within the TF's playback specs while sacrificing quality. If you would look at a source vs encode screenshot comparison you would see this. My point still stands that the stock player is better than MX/Dice/BS for transparent videos that push the TF's limits with high quality encode settings.
If you transcode, then you're already sacrificing quality. We're dealing with lossy formats here.
If you also have to hard-mux the subs, then loss of quality is just staggering.
More on topic, BSplayer introduced their own hardware decoding engine in newest release and it's now on par with DICE player (and noticeably ahead of stock player hardware decode and all other crap players that use it (MX, etc.). It also have better subtitle compatibility.
Sadly, seeking implementation is very bad (to put it kindly) and it still lacks subtitle correction due to framedrops, so that occasional framedrops will cause your subs drift out of sync.
hey, im trying bsplayer with some 720p files and works great. the only problem is that when doing hdmi tv out the subtitles show in the tablet but not in the tv. anyone having same issue?

i think it has something to do with overlay and last ota updates... dice player is doing the same. didnt have this problem before.

It happens when you use hardware decoding, if you turn it to software the subtitles show up but the video plays slow .. PM me if you find a solution please !
people should stop doing this. the stock player is fine when playing supported format. but what other ppl want is a player that play mkv files smoothly. till now, only dice player does it well, and I say this because tested it myself.
Newest BSPlayer is as good as DICE (builds from nov2011 and above). Test it out.

[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] Whats the best video format for a Flyer?

Hi all, I've got a Flyer 10.1 which has been upgraded to 3.2 Honeycomb. What is the best format to convert a movie to, is it MPEG or MP4? any help would be much appreciated!
Basically you are referring to the same format since .mpeg is MPEG-1 and .mp4 is MPEG-4. These are just different versions.
I think there isn't much of difference in which one you use.
Put any format, like mikpel said over me
But for watching the movies try to use the MX player... for the PRO version, just google it
If you get some lags on the video, switch to S/W and its gonna work better but just if the video gets lagy
There is a difference as an mp4 can be in various codecs such as h264 or xvid whereas a standard mpeg video cannot.
Most common mp4 formats use xvid or h264 video codec with mp3 or aac audio.
Flyer supports mp4 in h263, h264, divx and xvid codecs with mp3 aac or wma audio.
Best for quality yet smaller filesize is h264 video with aac audio but an xvid avi mp4 with mp3 audio can be played on pretty much any thing and is similar in quality though produces slightly larger filesizes.
