But I need to fix the source file permanently. In theory it should be possible to do it without transcoding. All the bits in the picture can stay exactly as they are. I assume it's just some labelling in the headers that needs to change so the picture is displayed correctly. I tried various ways to do this and failed completely.
So now I'm resigned to transcoding the entire video stream. But I still can't find a way to do it in VLC. I tried using a command like this.
Code: Select all
vlc myfile.mpg --aspect-ratio="16:9" :sout=#transcode{vcodec=mp2v,vb=4096,fps=25,height=576,width=720}:file{mux=ps,dst=vid020.mpg}
