Where can I find a list of all Media options in libVLC

Question

I used the command prompt command

vlc --longhelp

Which generates a long text file, but it's missing a bunch of options like

network-caching, or any caching.

Anyone have any insight into a complete list of options for the Media object in libvlc?

Answer 1

I know I am late to the party, but since it is 2024 ,and I stil needed this list and couldn't find it anywhere, I looked in all documentation and created this list bellow.

Hope it helps. Happy codding!

      --sout-udp-caching <integer> 
          Default caching value for outbound UDP streams. This value should be
          high values, you will need to raise caching values.
      --sout-rtp-caching <integer> 
          Default caching value for outbound RTP streams. This value should be
          caching at input.
      --file-caching <integer [0 .. 60000]>
