Assume I (lossless) re-package a video file with original container A into another video container B (e.g. AVI or MKV or MP4)
with an ffmpeg container like
ffmpeg -i myvideo.<sourceextension> -vcodec copy -acodec copy myvideo.<newextension>
Does ffmpeg AUTOMATICALLY recognizes the target container type from the extension of the target file name?
If yes: Why do I sometimes see sample commands with an additional flag like
ffmpeg -i .... -f AVI ....
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!
