can anybody confirm that mp4-files with more than 1 audio stream work on the gallery app player?

so when i want to play this mp4-video with the mediaplayer integrated in the gallery app. it is indexed but it wont play. when clicking the video the screen becomes black and a second later goes back to the "ready to play" position. repeatable forever.. nothing happens.

i will give information about the file, maybe somebody sees where the problem is...

1 video stream, 2 audio streams

type: video

  • codec: H264 - MPEG-4 AVC (part10) (avc1)
  • resolution: 720x576
  • fps: 25
  • format: Planar 4:2:0 YUV

type: audio

  • codec: MPEG AAC Audio (mp4a)
  • channel: stereo
  • sample rate: 44100 Hz

type: audio

  • codec: MPEG AAC Audio (mp4a)
  • channel: stereo
  • sample rate: 44100 Hz
  • bits/sample: 16
  • bitrate: 1411 kB/s

edit: in search of similarites with other non-working files i found another one with the exact same encoding. edit: i found that all my working mp4-files only have 1 audio stream

well, thats what vlc tells me. and vlc plays it without any problem. got any idea what i could do to further investigate? i had other mp4-videos in the past that didnt work... i could look more file and look for similarities....

@vasavr i just checked the info of some working files i use and some of them have the same codec identifiers and the same (weird) bitrate - but are working.

i found a difference though... all working files only have 1 audio stream!

I can confirm. Encoded a test file with AVC video and two AAC audio tracks and playback refuses to start when I press play.
