VLC command-line

Convert video files to mp4 video files.

Using common parameters

  • -I: dummy Does not show the VLC GUI
  • -vvv: Gives you verbose output
  • --sout: Specifies the options to use when encoding to MP4
  • vlc://quit: Quitter VLC after finish.

Examples:

Single file

vlc file --sout='#transcode{vcodec=mp1v, vb=1024, acodec=mpga, ab=128}:std{access=file, mux=mpeg1, dst=C:\file_name.mpg}' vlc://quit

vlc -I dummy -vvv MyVid.mod --sout="#transcode{vcodec=h264,vb=1024,acodec=mp4a,ab=128,channels=2,deinterlace}:standard{access=file,mux=ts,dst=MyVid.mp4}" vlc://quit

vlc -I dummy -vvv AVSEQ01.DAT --sout="#transcode{vcodec=h264,fps=16,acodec=mp4a,deinterlace}:std{access=file,mux=mp4,dst=AVSEQ01.mp4}" vlc://quit

Multiple files using powershell

foreach($f in Get-ChildItem . -Filter *.DAT) {vlc -I dummy -vvv $f --sout="#transcode{vcodec=h264,acodec=mp4a,deinterlace}:std{access=file,mux=mov,dst=$f.mp4}" vlc://quit}
  • .: The folder (.: the current folder), to get al the files in the current folder with the exetnsion DAT.
  • -Filter .DAT: .DAT is the extension of the files to convert to mp4.
