[bug] mp4 video does not play [answered]
asked 2015-11-07 10:36:56 +0300
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
codec: MPEG AAC Audio (mp4a) bitrate: 1411 kB/s
Doesnt seem right.

i found a difference though... all working files only have 1 audio stream!
misc11 ( 2015-11-09 14:49:07 +0300 )editI can confirm. Encoded a test file with AVC video and two AAC audio tracks and playback refuses to start when I press play.
