[vlc] Re: Using vlc to show video through another app

[Felix Mellmann]

You may save the incoming stream to a file and send it afterwards to VLC, so
you have a chance to see, if VLC accepts the stream which you get over the
serial link.
Is the stream which you send packed in a transport stream e.g. MPEG2-TS? I
wouldn't prefer to use an avi-container.

Felix
