Ok for last couple of days i've been trying to play movies on my x10. I've tried many players from the market and so far the results are:
Stock Player: Couldn't start/play any of the file.
Arc Media: Sorry, this video cannot be played.
Soul Movie: This video cannot be played! Please contact to the phone maker!
mVideoPlay: Sorry, this video cannot be played.
QQPlayer: Starts but wouldn't play anything (Force close when trying to go back)
MX Video Player: Starts well, loads subtitles and goes on for 5-10 mins with a little lag (which is fine for me) then starts to lag like hell and then video goes out of sync.
The video I'm trying to play is a BRrip, resolution is 1280x528 and is in mp4 format. (HD music video's I've downloaded from youtube seems to work fine with any player which is in same resolution) Some other movies in .avi format and lower resolution would play in some of that player but lags like hell.
NOTE: I've tried to set different settings of different player such as hardcoding and softcoding but they didn't work.
Any suggestion guys??
So only that BRrip doesn't play? You say youtube vids are ok...
Try Vplayer Pro, it works smoothly in my phone, so far i havent meet lags when playing any vids.

Ough..BRip in MP4..you mean in MP4 extention, isn't it..
Try to convert it to 720p resolution and change the Video Codec to Mpeg4 H264..
Can't play coz the resolution is not support by the player/phone..I guess..

No need of any conversion buddy, install mobo player from Market. Its free app. It actually plays anything u throw at it. Using it for over five months now. Plays even youtube .flv HD files flawlessly (Make sure the resolution is 720 or less). All the best...
Convert it to the same res as the x10, rather than letting the x10 do it on the fly. Your bound to get better results.
Try Mobo player. Plays any format and supports subtitles in .srt format. It would be nice to have option to change audio tracks in dual-audio files but at least works flawlessly.

Ok guys I tried mobo player it works, I mean it plays the file but it lags and gradually goes out of sync. This time the file was even in lower resolution. But convert seems to work fine. Now im gonna try different movies in different resolution and check which works and which not. Then I'll let u guys know. But in the mean time can u guys suggest me some good converter for x10? And the settings for those converter. I use Avs converter but its slow as hell.
Oh and guys I'm on cm7, just so u know.

MP4 is a simple format and can be easily played on our x10 on 720p(1280x576,1280x720)
MKV is used in Blu-rays now a days...
It can have many audios like a movie in 2 languages...
I play it in my x10 dual audio 720p...
The main thing is use doomkernel and overclock to 1228Mhz in interactive mode use MX video player.
Sorry if it sounds noobish but how do I use doomkernel and overclock in enteractive MODE?

I'll never understand why people want to watch 720p on a non-hd device. It's only eating up your resources.
Whether or not you can play videos depends on bitrate mostly but there are other reasons vids won't play. Just because 1 720p movie works doesn't mean they all will.

Hi everyone, is it possible to play 720p (1280×720) movie on X10 smoothly? If so then which program did you guys use to convert and which encode did you use? Because I did try both .mkv and MP4 H.264 encoded and it seems to be lag or super slo-mo alike. Really appreciate with any help from you.

Ya u could download the apk file called rockplayer.apk and install it and throw any file in your memory card and this app will play it smoothly
I did use Rockplayer to play but the result was somewhat unsatisfied. I got lag and slow motion video play

You could try yxplayer, but that's probably going to do the same thing...
So noone suffers the same prob as me? Everyone can play HD video smoothly. Can I ask which codec did you use? I used MP4 H.264 one
Sent from my X10i using XDA App
I have the same prob.
Lag on rock player playing 720.
Just like lag in phone overall
Can I ask why you need HD playback on a none HD display? You would not see any difference from a 720p file to a 854X480 file regardless.
The Ironman file I encoded to the proper size plays perfect and I cannot tell the difference from source (720p). Encoded MP4 H.264 with Videora.
I just tried, and in mp4 format, it lags significantly (like it plays between 7-19 fps), but I converted the same file to DivX, picture and sound quality looked exactly the same and it plays perfectly fine at full frame rate.
Well, probably the 2.1 update will bring something to play HD video, since the X10 will be able to record HD video. At lest it is logical.but who knows, maybe we ll record on our X10 the video and watch it on a hd tv. i hope i am wrong.

My thoughts exactly. Unless we're able to output and watch these files on our HDTV's, whats the point of needing to watch a 720p file on a 854x480 screen that isn't HD? Makes no sense to me...but to each their own.
I recall reading the update info on SE blogs that we will apart from HDrecording also get wireless video out, i'm guessing we'll need to buy some reciever for our tv's for it to work.

Personally I want to be able to play 720p video on my phone because that's what format the majority of my video is and I'd like to be able to play it without transcoding
That said, If I remember correctly the snapdragon has a hardware video decoder capable of playing 1080p @ 30 fps so it is probably a 1.6 related issue.
hi mate i just got the phone today its amazing for i have a question whats XDA App that u use for transfer the file i guese??
My guess is that these video players do not have access to the GPU for hardware acceleration, which would mean the CPU would have to do all the hard work (don't forget, playing HD video IS hard work for any mobile device). Whether that would be an Android 1.6 restriction, I don't know.
anybody looked at the bitrates of these videos?
a bitrate of 8,000 in comparison to a bitrate of let's say 1,000 would make a bit difference... am I wrong?
Also, if you are using the stock CLASS 2 memory card, then playing high bit-rate files will be problematic.
I know that you guys don't want to transcode, but 720p really kills battery.
I haven't tried on my new 16GB class 2 card, but with the 8GB that came with the phone I got smooth playback with 720HD with these settings:
MP4:
ffmpeg
1500kbps for video
48channels or whatever it is
160kbps sound
1280x720 pixels

Does x10i plays full HD videos?
If yes then is.there any specific video player to play it?
Sent from my X10i using XDA App
Yes ofcourse it does, only with 2fps
Haha is there anyway to play it properly? Smoothly?
Sent from my X10i using XDA App
Atleast with the 2.2.1 rom, it plays 1080p quite nicely. IF and ONLY IF, it can use hardware decoding, which requires the video to be in h264 or mpeg4 in mp4 container and even then, it's still some settings that needs to be set specificly and stuff but I dunno what those restrictions are exactly and from searching for several days, I have found noone that knows that. I've come to the point where basicly, I just try and see if a video works.. Sometimes it does, sometimes it dont. If not, reencode to mpeg4 using SUPER using "No change" as the aspect, and it works fine to play after that..
dude seriously why the hell do you want it to play full hd? your resultion is around
850 x 480
you really want to play a video with 1920x1080 ? if you got at least 10 gig of space on your sd card for one movie you can try it ... but be warned ... your watching a "high quality" video that gets shrunk so it can fit on your "tiny" screen ....
edit: just download Super (http://www.erightsoft.com/SUPER.html) and optimize it for your phone ... so you always have the perfect resolution (no scaling)
Yes it dose smoothly...use Vplayer....
Hi there, I been searching around regarding this HD Video playback issue but till now there are just like half half situation. Some people claimed their device can run smoothly for 720P video but some said can't, therefore I would like to ask about this question again.
I have tried out few HD trailer in 720p mp4 format, coded in h.264. My result was out of 10 720P video I tried, only 2-3 able to play smoothly in my x10i, the rest will either have video lagging or require soft-decoding which will cause in video lagging as well. In short, my x10i can't play 720P well.
I have another solution in hand which is converted them still into h.264 but in resolution of 854*480, and all of these converted video worked fine. Just wondering if most of the x10i user able to play 720P video smoothly or not since conversion requires some times... Also wish to know is it the real hardware constraints for x10i to play HD video or only my device having some processing problem...
Nevertheless thank you for your answer and opinion =)

I tried moboplayer, rockplayer, vplayer. They all won't able to play it smoothly, neither hard-decoding nor soft-decoding. Hmm your video size is 1280*720 or above? As far as I concerned 480P already consider as HD and my phone is able to play them well as well.
I understand there is no point playing HD on x10 screen, but all my video source are in HD format and I would like to figure out x10i capabilities in HD playing so it may save me some time doing video conversion

Okay so I didn't really think I would have this problem with this phone. I put a mkv video on my phone and I went to go watch it but it stutters I'm not sure how to explain it but it's really choppy. It doesn't complete freeze though. I was using this in the stock video player. This was because I wanted to try pop up play. So I was bummed that I couldn't use the stock player which is the only one that does pop up play. So I tried mx player but it also has the same problem playing back the video. Wth can the s3 not handle mkv videos? I didn't have this problem on my note. Does anybody else have this also? Is there a fix or something? The screen is beautiful but it's not smooth playback its too choppy.

Need more information. MKV is a container codec, not a video or audio codec. What is the video and audio codec, and is it using something like 10bit color?

I've seen that happen on Epic Touch with most mkv format videos.
Try RockPlayer.
Yeah I was also having problems with certain video files. A couple of .m4v's that I tried to put on my phone would crash the video app if I put in or pulled out my headphones while the video was playing. Seems to be isolated to particular file types/codecs.
what is the res of the video you are trying to watch. what is the actual video codec on it and are there subtitles?
You could try VLC for android:

Try something for me , connect phone to your PC thro USB , and then try playing video on your phone , report results ?
I'm not sure how to see what is the actual video and audio codec, how do i check it?
The video files are mkv 720p blu ray rips.
I tried connected my phone to my pc via usb and tried playing video like you said and i couldnt really see a difference.
I think we need to wait for the video player app developers to produce extensions that work with or provide true hardware acceleration for our new hardware, the best player I've found right now for the GS3 is BSplayer lite.
Ironically BSplayer gave me the worst performance on the GS2.
anyway try BSplayer lite on your GS3.
720p bluray rips will kill most portable devices they are MUCH higher bitrate than a standard 720p movie. you need to downsize them if you want to play them smothly
Try MXplayer with their ARM7 codec pack.

I also experienced problems with the 720p .mkv files I ripped my blurays to for portable use - but moreso with sound being out of sync with the video. I had the same problem with my GS2 when I upgraded to 4.0. I re-ripped my whole collection using the same compression rate into .mp4 and they all play flawlessly now. Anything I have that is .mkv simply doesn't play nice on both my GS2 and GS3 with 4.0.

MKV is not a codec...it's just a container format like AVI.
From my experiance/experimenting biggest culprit is always "stagefright" being enabled , screws up hardware decoding on many levels. On my ATT GS3 , it was enabled by default, i could not play my 720p 60fps music videos , i got "Blade Buddy" it lets you mess with some system settings easily (however i dont know witch setting specifically triggered it), after messing with it and doing soft reboot , my GS3 now performs as it should , can play even higher then 720p , latest one i tried was 1440x810 @ 60fps High profile H264 , all smooth and nice , [email protected] was to much though , all common <=30fps videos play problem free.
In Blade Buddy under Basic settings i toggled off "Compatibility Mode"
Under Advanced settings i toggled off stagefright , then hitting menu button clicking apply , and selecting soft reboot.
There must be something wrong with your setup or codecs or i dont know what because i have a NAS and i STREAM 720p blu-ray rips of about 5gbs a movie off my HDD attached to my router, i stream them and get 0 lag, even when i advance the movie, it takes 1/4 of a second to buffer and play the movie, and again i get 0 lag. i use BS player Lite
so its not the phone, trust me
I have played mkv videos and I have no problem ... the video format is hd 720 mp4
Sent from my SGH-T999 using xda app-developers app
So it seems that some people can play 720 blu ray rips just fine with no problem while others can't and need to change the format. I find this rather odd. I haven't tried streaming these videos but ill try and report back but I think it would be worse because if it can't handle playing from the device the added pressure of streaming would make it worse. Somebody mentioned audio being out of sync, I don't have that problem at all. And it's not like the video is severely laggy its like it plays but it stutters as it goes to the next frame its so hard to explain ill see if I can record it and show you guys.

for a 720p bluray rip/hd rip movie, i still run it through handbrake to get the file size down. i set res to 1280xtakewhatevericanget from the original source. output as mp4 in that case (still h.264). i tend to crank the audio up a bit too, since it helps on airplanes or whatever with movie dialogue.
i haven't really tried dragging over a full on 4+gb 720p blu ray rip .mkv file...then again mtp sucks ass, so i'll do anything i can to get file size down.

Fat32 maxes out with 2GB files.
it's not the mkv that's causing it's issue, it's what's inside the mkv that's causing the problems. not just codec but bitrate and other small things could matter. Also, if it's software and not hardware like the ipad, even if meets the criteria hardware wise, it can cause an issue.
720p mkv that need software decoding lag (doesn't play in default player). Mx player seems to stop for few frames then jump forward and then play normally. In Vplayer video slows for a bit then seem to go faster then normal and then slower - repeat.
This is bad...

Try VLC Media Player !!
I've found that default player is laggy for mkv movies at 1080p. I tried poweramp (which I think is one of the best players) and I couldn't get the video to show up.
Then, I tried the VLC beta app, and like on my desktop is the best player for mkv files. No lag at all on a 1080p movie. Btw on a 90 minutes movie battery only ~20%

Did , VLC vomited and stoped working after attempting to open.
But i did some digging and i learned that the issue is with 10 bit color coding. Hardware codec only works with 8 bit and so 10 bit needs to gets processed by software putting all load on cpu. Its easily confirmed by running 1080p 10bit that starts losing sound due to the load.
However 720p @10 doesn't lack much to be smooth so i think with oc it would go fine. But first i went searching for alternative to MX player.
Bs player got option to skip frames when behind and it smooths out video but audio goes out of sync after a while. After some more dead ends i found someone suggesting Archos player. And it works :victory: . I can't see any lag on my test sample anymore , another file also worked fine.
Guess im saved :]

Bs player got option to skip frames when behind and it smooths out video but audio goes out of sync after a while. After some more dead ends i found someone suggesting Archos player. And it works :victory: . I can't see any lag on my test sample anymore , another file also worked fine.
Guess im saved :]

I use BSPlayer on my Samsung S2 and I think it's the fastest out there. Can you try it?
EDIT: oops... you have already tried it...
Use bs player or the archos video player plus the free codec pack.
I found MX player struggled with some of the MKvs I had until I turned on hardware Decoding. Everything's been fine since then.
TBH it's a shame the Movies app doesn't have all the audio codecs or gestures as it's quite a nice interface and can see all my XBMC uPNP content.
