Problems video playing in some android devices (version 4+) but not in others
5 juin 2014, par anquegifollowing the settings for video in android developers, http://developer.android.com/guide/appendix/media-formats.html I encoded a video using ffmpeg like this :
ffmpeg -i gravityTrailer.mp4 -y -f mp4 -vcodec libx264 -profile:v baseline -acodec aac -strict -2 -profile:a aac_low -b:v 500k -ar 44100 -b:a 128k -ac 2 -r 30 -s 480x360 output_hq.mp4which corresponds on sd highquality in table 2 from android developers (link above).
Then i put this video in a server and use the class android.media.MediaPlayer to reproduce it from that URL like this
https://cloudapp.somedomain.com/bmftvideos/output_hq.mp4
The problem is that the video is played on android version 4+
you can see the video on :
LG G2,
Sony xperia Syou cannot see the video on :
Samsung galaxy S4,
BQ (spanish) aquaris 4.5And I don not know why
this is the ffmpeg output :
