  61c5e94 Use -1 consistently as invalid buffer idx
  update the initialization in swap_frame_buffers() to match.
  additionally :
  - remove some shadowed variables in the former and marked them volatile

• 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 ?
