>>106033it does. where do you think its libraries (avcodec, avformat, etc) come from? every free tool has ffmpeg under the hood. it would be insane to write your own libraries with ffmpeg readily available.
>>106021Avidemux has amazing trim and crop tools, but only offers limited export (e.g. no webm, discards subtitles, etc) and is a little bit picky about input (prone to crashing with VP8, needs YUF colour space, etc).
for basic editing of x264 i'm using straight-up Avidemux. for anythig advanced i use Avidemux to scout the precise frames for trimming and the pixel values for cropping and then i write them manually into the ffmpeg filters.
here's a video showing off Avidemux i did for a tutorial thread i wrote about a year ago.
