    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 :

    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

  • ffmpeg "Option preset not found."

    2 février 2015, par PiTheNumber

    I am trying to convert a .mpg to .flv with ffmpeg. On other servers I got it working but here with the ffmpeg clone (avconv) it just does not do it.

    Originally I was working with libfaac and preset fastfirstpass but thats not available in this build so I switched to the experimental acc and preset libx264-fast_firstpass :

    $ /usr/bin/ffmpeg -i /data/upload/videos/original/150128_Test_731_9d5b83.mpg

Option preset not found.

    What does the error in the last line mean ?

    I already made sure the preset libx264-fast_firstpass.avpreset exists in /usr/share/avconv/ and if I change it to invalid ffmpeg complains with Preset invalid specified for stream 0:0, but could not be opened., so the preset is correct.

    Google does provide two results for this error. This chatlog and it’s pastebin about live streaming with the solution to add -f flv and some russian page. Nothing helped.

    Any advice ?
