A file you can play consist of a container, mp4 mov ts flv avi etc, think of it as a bottle This container contains a video and an audio stream, each of which are encoded with a codec. Video codecs are h264 h265 xvid mpeg2 Audio codecs as aac ac3 etc Further the container contains time codes and other things. mov and mp4 are containers which have a lot in common but are not the same. So with c:v copy a:a copy from mov to mp4 you ‘tell’ ffmpeg to put the video and the audio stream, unaltered, from one bottle into another form of a bottle. Not every container can hold all kinds of codecs. You have to google to find your way, what can and can’t be done. > > > > > On Wednesday, June 24, 2015 2:25 PM, Henk D.
