ffmpeg "Option preset not found."
2 février 2015, par PiTheNumberI 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
avconv version 9.16-6:9.16-0ubuntu0.14.04.1, Copyright (c) 2000-2014 the Libav developers

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 ?
