Mkv Video loads in the preview but doesnt play

[invinciblegod]

So my problem is that my video file doesn't play with a message that says play audio data only. This would seem to indicate that the video codec is not supported. However, what confuses me is that it was able to generate animated previews in the selections screen. How is this possible and is there a way for the decoder hardware to force it to decode? Also, software playback would not work since the phone is not powerful enough. I would even be happy if the video plyer drops frames but keeps in sync with the audio. The video file uses the AVC codec. File information below. Any help would be appreciated.

Like I said, software solutions don't work because they are too slow and don't drop frames to keep up with audio or subtitiles (as in they play at half speed).

I find BS player works pretty solid for me.

It doesn't work because your video is Hi10P , hardware decoder can't handle that , and software decoder doesn't have power to decode HD Hi10P.

Recode to normal h264/x264 , or download. Even international version with quadcore cpu drops frames.

If you dont know what Hi10P is , google it.

Ok this worked because it drops frames properly so that it syncs with audio. Thanks for the suggestion and I will use this for now. It works better than Rockplayer, mx player, and VLC beta since all of them try to render every frame with decreased speed instead of dropping frames.

Unfortunately, this is still not ideal because it still has to drop frames. Unless the default video player generates previews using software and then plays back in hardware, the animated preview should show that the hardware decoding works with this file. Don't know why it doesn't though.

Oh thanks for the explanation. Wonder why the previews work though.
