  • 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
    
  -strict experimental -acodec aac -ab 128k -ar 44100 -vcodec libx264 -pass 1 
    
  -pre libx264-fast_firstpass -b 512k -s 360x204 
    
  -f flv /data/upload/videos/encoded/150129_Test_731_54f06a.flv

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 ?

  • 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 rotate and resize

    30 mai 2019, 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 ?
