I use: 

avconv -i '/INPUT.MOV' -vcodec libx264 -vprofile baseline -acodec aac \
-strict experimental -r 24 -b 255k -ar 44100 -ab 59k 'OUTPUT.mp4'

The conversion is done correctly and smoothly plays PC / MAC, but the video does not play on mobile devices.

Does anyone have the same problem? How to solve it?

  • you may need to use -pix_fmt yuv420p [also ffmpeg git master?] – rogerdpack Apr 29 '14 at 15:42
  • I added the new parameter and both ffmpeg as aconv continues without displaying on mobile :( – user3584988 Apr 30 '14 at 06:54
  • well I'm not certain... http://stackoverflow.com/questions/21801240/ffmpeg-mobile-video-encoding-stutter or http://stackoverflow.com/questions/13560852/convert-mp4-to-maximum-mobile-supported-mp4-using-ffmpeg may help – rogerdpack Apr 30 '14 at 12:07
  • Mobile: Android and iOS have very particular screen size and audio settings. Add: -s 720x480 -aspect 1.77 Change: -ab 59k to -ab 56k and -b 255k to -b 800k (or higher) Put '-strict experimental' just before -acodec – Andrew Apr 30 '14 at 17:29
  • Hey Andrew, thanks for your response, but does not play. I use now: _avconv -i input.MOV -vcodec libx264 -vprofile baseline -acodec aac -strict experimental -s 720x480 -aspect 1.77 -r 24 -ar 44100 -b 800k -ab 56k output.mp4_ This is the command I use, you see something wrong?? – user3584988 May 02 '14 at 06:54

-strict experimental goes before -acodec.

In your script it is written after -acodec
