[vlc] Re: VLC Stream to File issues

[Sigmund Augdal]

Not going to solve all these problems with my simple reply, just wanted to
point out that using VLC's stream output is not the same as dumping the
stream vlc gets. to dump the exact stream vlc gets use a command like this:
vlc udp/dump: --demuxdump-file=/my_dumped_files/from_vlc.ts
