ffmpeg command failed
25 octobre 2015, par Asad kamranI am experimenting FFMPEG command to convert any video format to mp4.
Server admin execute the below command created by me and show me the errors :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpgThis is error :
[aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
codecs are not enabled, add ’-strict -2’ if you want to use it.how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.
my ffmpeg and server are as follow :

I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :New command :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpgAfter executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
