ffmpeg -ss 519 -t 102 -i myinfile.avi myoutfile.avi -vcodec copy
gives me a file but "misses" the key frame at the beginning
i.e.
[mpeg4 @ 0000000001F99050] warning: first frame is no keyframe
As such the file when played is just all gobbledygook until it hits the first key frame.
Is there a way I can get ffmpeg to "go back" to the nearest key frame.
so if for example if it is 5 seconds previous to my required 519 seconds in just clip from there instead (automatically) ?
Help much appreciated.
