• ffmpeg rotate and resize

  23 août 2014, par user1321964

  I’m trying to resize a movie and to rotate it counter-clockwise using ffmpeg.
  I can achieve one or the other ok individually

  ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

  OR

  ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

  but if I try to do both, either-

  ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

  ffmpeg -i resize.MOV -vf "transpose=2" toutp.MOV

  OR

  ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

  ffmpeg -i rotate.MOV -s 406x720 toutp.MOV

  the final movie does not play, only audio, no video ; neither previewing in Finder, nor in Quicktime. More seriously once I have attempted to play it, I can’t then play any other movie whatsoever (only audio) - quicktime won’t quit, constantly need to force-quit it. The only way to then restore seems to be reboot OS-X

  This though does work -

  ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

  ffmpeg -i rotate.MOV -s 720x406 toutp.MOV

  but doesn’t do what I want - it stretches the movie in the wrong direction

  Any ideas ?

  I’ve tried adding sleep(5) after :

          exec($cmd, $out, $ret);

  to give the script time to move the moov atom to the front before uploading the local file to s3 and then deleting the local file, but it is not 100% reliable.

  Any ideas ?

• Why ffmpeg convert only the first frame of my animated gif ? [duplicate]

  23 novembre 2016, par Cyriltra

  This question already has an answer here :

  • convert animated gif to video on linux server while preserving frame rate
    
    2 answers
    

  My animated gif is around 37mo and last for around 10sec. I use the following command on debian to convert it to .mp4 :

  avconv -i test2_37m2.gif -pix_fmt yuv420p -vf \"scale=trunc(iw/2)*2:trunc(ih/2)*2\" test2_37m2_mp4.mp4 2>&1

  The result is a 14kb .mp4 which is just a static frame (the first one) of the gif. Why ?

  here is the output log of ffmpeg / avconv
