720p Playback lagged

Hey guys,
I'm using the MHL Adapter from BizLink and tried viewing a 720p movie with DTS Sound.
The playback lagged . I don't know why..
I used the Dice Player, because it's supporting DTS, also i'm using a 5m HDMI cable.
But why is the movie lagging? There are kinda microlags..
Resolution: 720p
Video Bitrate: 5586 kbps
Audio Stream: DTS 5.1
x264
Maybe the Player causes the problem, because another 720p movie was played well (Samsung stock player). btw: the phone was very hot after watching the above mentioned (DTS) movie.
Does anyone has some ideas?

Ya some 720p movies also lags for me in Dice player.Its better to convert DTS audio only to ac3 format,doesnt take too much time either to convert.

Guess it's the best way to do.
Just watched a 1080p movie, and the phone was only a bit warm (with samsung stock player), was AC3. Does anyone know a "good" converter from DTS to AC3?
i had to split the movie into 3 files, to be able to play the movie (4GB limitation).
Maybe Samsung will fix these two issues: DTS capability and EXT4....

Diceplayer prior to 1.2.0 have some video lag issue.
did you test the movie using diceplayer 1.3.0 ?

I was using the 1.3.0 version.
Watched 1080p without any lags, yesterday. Was using stock Player

As far as I know hardware-acceleration an Android will only be used when using the integrated media-framework.
While Samsung extended the stock media-framework to support more container and codecs (like AC3 for example) it doesn´t support DTS.
This means, anything you can not play with the Samsung mediaplayer will use pure software-decoding, which is slow and burns a lot of energy.

This is no surprise. With software-decoding, which obviously isn´t fast enough, at least one, but probably both of the Cortex-A9-cores will run at full speed the whole time.
The reason for dedicated decoding-hardware in the SoCs instead just using more powerful general purpose CPUs is the much better energy-efficiency.

Yes, i thought the same, because it was so warm.
I used the Rockplayer, with it you can activate Hardware acceleration, but i don't know if it works.
Thought other players could use the hardware acceleration.
From now on, i will convert the DTS to AC3, but first of, i will look for stock AC3

Rockplayer can use hardware-acceleration, but only using the Android-Framework, which means hardware-acceleration will only work for the same containers/codecs as with the stock mediaplayer.

As I said Players can use hardware-acceleration, but they have to do it using the media-framefork, which means no hardware-acceleration for containers/codecs which aren´t supported in the media-framework.
In theory you could develop a mediaplayer with your own media-framework, directly programming the SoC.
But the question is how much of use it would anyway, could the hardware assist decoding for codecs which aren´t already present in the media-framework? It certainly could be useful for unsupported containers, that contain codecs which are already supported.
But the biggest problem would be that your new media-framework will only work with the phone you developed it, nobody will make android-software for just one phone out there.
That´s somewhat of the curse of the Android-plattform. It has been developed for maximum compatibility between the different devices out there. This means lots of choices in devices to buy for us, and for software-developers many devices that can run their software. But it also means we are not getting device-specific-software from 3rd-party developers.
Hopefully the Android-Framework at some time will split up the media-framework into "modules" similar to a DirectShow Filtergraph, so mediaplayers could exchange this individual modules and still use hardware-acceleration in others (which come from the device-manufacturer)
This would allow for example the support of different containers without losing hardware-acceleration in the decoding-part (if the codec is already supported), as well as doing audio-decoding in software (which could be quite reasonably done with 2 Cortex-A9-CPUs) and still using the hardware for the video-part.

I never hadany lag on the stock. Even the 1080 ones

Diceplayer use SoC's HW Decoder. + SW decoder for Audio.
check this video
After Diceplayer came out, all of android device that supported by diceplayer
can play MKV(H.264/MPEG-4+DTS/AC3).
Even Nexus-S can play MKV+DTS+H.264 High profile with Diceplayer.

mal-formatted mkv file can cause some lag.
H.264 need 2-type of frame time - PTS/DTS.
but some of MKVs have wrong time stamp.
SGS2's HW Video decoder can not handle these files.

720p videos not working...

Hi! I have problems playing some videos, particularly 720p movies that I downloaded via torrent. The video format is .avi and i'm using a class 10, 8gb micro sd card. It says unable to play video when i try it on my GW. The video plays fine on my pc through VLC media player, but when I try playing the video using DivX player, an error pops out about audio codec... (forgot the exact error type name) So I assume that the problem is the audio format. Is there any app that can solve this problem? Thanks in advance!

Try MX Video Player. An AVI-File is just a container, so it can contain different video and audio-codecs which the Video player (whether PC or Smartphone) has to support.
greets
THE-E

I will try it as soon as I get home. Thanks! One more question about this app; what are the other codecs for? should I download and install them all for my GW? Sorry but i'm really clueless about video formats and stuff.

May I..??
No need to download any codecs...in my exp,..it's support any vid format.but in particular case,if u want using h/w(hardware) accelerator playing some vid playback and it says doesn't support,just download mx armv7 neon codec...but if u still in stock rom,no need to download that codecs..

Or try Mobo Player. I have positive experience with it.

Use software decoder

Okay, I downloaded mx vid player and the 720p video now plays with a sound but there's a problem; fps was quite low! the video doesn't play as smooth as the other videos that i have.

Nahh..no need to download that mx codecs if any 720p vid run...its just wasting ur space...
Buy a fullhd phone if u want a super-smooth fps..!xP..(kidding bro)
Try to switch between h/w decoding or s/w decoding when playback ur vid..tap on screen,u can see on right side there is small decoder option..tap it and choose between s/w or h/w....feel wich one suite u well..there's a small diff in fps on each decoder.

I don't think SGW supports 1080p videos. I personally haven't tried yet, but downloading 720p and playing them on my phone works perfectly fine for me, thus I haven't tried the highest resolution. But I don't think our phone supports it.

OK, tried this with Dice Player!!!!
Downloaded 1080p with TubeMate.....very good App, allows You Tube d/l, at all resolutions from 1920 x 1080 [Galaxy Tab, PC] to all other.
No workee!!!

I use Tubemate to download videos too! A very good app (though I'm having difficulties on playing videos from it).
Perhaps that's why Tubemate stated that the highest resolution video for mobile phones are only for high resolution devices. So perhaps SGW isn't one of them.

Erm... This problem goes down to the chipset. The MSM8255T was never designed to handle 1080p. Adreno 205 cannot handle encoding and decoding of 1080p video. This makes it totally impossible for hardware decoding. You can only do it by software decoding (Untick hardware decoding, I called it software decoding since I don't know what other term should I use). Yet, our processor is not powerful enough to do the software decoding. I tried with VPlayer, 1080p does play but with laggggggggggggging video, audio is fine though.
EXTRA: For your information, Samsung Exynos chipset used in Galaxy S/Nexus S (means the phone earlier than ours, perhaps also an older chipset than ours, never verified this though) with the SGX540 GPU is designed to handle 1080p en/decoding. I'm not sure whether it works in Galaxy S or Nexus S but it's possible since their hardware is designed for that.
I did the reading quite sometime ago because I found out P1000 (Old Galaxy Tab) can handle 1080p with similar chipset (as Galaxy S/Nexus S). Just to help out a little bit =)

@FutureGamerz: a very interesting explanation! You have my thanks for that.

Thanks for all your response guys, but it would be nice for some kind of trick to enable hardware decoding, some kind of force script to enable always hardware decoder.

Movies on ascend P6

I have a problem. I copied 2 movies on sd card and tried to watch them today. One was brrip of 1.40gb and one dvdrip of 1.40 gb. Both movies were frameing with the default player. With mx player the things improved only a little when i was using S/W decoder but it still wasn't near to being fluent. What's the problem with this device. I thought it plays even 1080p videos fluent. Can somebody help me with an advice?Maybe i did something wrong?

Certain codecs are missing from android, meaning that h/w can't be used to play them. 1080p is not that easy to play when there is no GPU supporting the CPU. *.mkv and *.mp4 files should play fine, since those both are usually h264.
http://developer.android.com/guide/appendix/media-formats.html

So this means .mkv and mp4 will play fluid till 1080p and files that are lower resolution than hd but are .avi will play jerky? No solution for these ones to play fluid? I tried with mx player (arm v7 neon) but almost the same.only a bit better.

The problem is they weren't even hd. this is the file name "Jack.Reacher.2012.BRRip.XviD.AC3.RoSubbed-playXD.avi" 1.46gb and i verified also its resolution which is 720x300 or something like that. That's why i am confused. Low resolution like this should play without a problem even if it does use software decoding right?

I use mine for playing movies and have not had any problems even with the avi. The only issue I have is when streaming anything that is 720 or over. The nexus 7 seems to be able to play anything I throw at it over the network when the P6 some times stutters.

Query regarding video playback

So i downloaded a 2160p (3840x1606) video and its not playing as it should. When i play it there is a lot of lag. I am using mxplayer.
I was hoping for it to play since it does record 4k videos. Can someone tell me if there is a way to Watch these videos properly on mzp at all?

There's a problem in the video not in the device.
Download another video and try.
(Don't DL it from the same site from where you have downloaded this video)

Did it. This one is 3840x2160. Same result in mxplayer and vlc.
Can someone else try it? Coz am pretty sure this device doesnt play the actual 4k. Coz the one it records doesnt really look like one.
