[vlc] VLC Stream to File issues

[rettw at rtwnetwork.com]

I have been researching an issue with VLC's stream out
capabilities.  I have noticed that other open-source
players seem to have issues with the TS or PS files that
VLC creates.

It seems that xine cannot play PS files created with vlc
at all while Mplayer can.  The xine team feels that the
issue is something in VLC, since they have not had issues
with xine playing PS files from a multitude of other
sources - I fact I have been using xine for 2 years and
haven't found a PS that it couldn't play, except for
VLC's.  The interesting thing is that PowerDVD and WMP
seem to play them ok.  I am continuing to work with the
xine team on this issue as well.

The other issue is with TS files.  When streaming a DVD
from VLS to VLC over a network, and then using VLC to
restream back to a TS - Both xine and mplayer play the TS
files ok, except  that there is no audio.  The really
interesting thing is that both xine and mplayer can now
receive the TS over the network from VLS via there own rtp
input plugins and play them with audio.  Both of these
programs use the same demuxer code for playing the TS
(whether encapsulated in UDP or a RAW TS file).  This
leads me to beleive that the stream out code to a TS file
produces a TS that is somehow fundamentally different that
the TS/udp that VLS sends over the network.

Another thing that points to an issue in the VLC stream
out code is this:  Mplayer can also dump the raw stream
that it receives from any source - very much like VLC's
stream out to a file. When using mplayer to receive a VLS
streamed DVD over the network and telling mplayer to dump
the stream to disk, both xine and Mplayer can play the
stream WITH audio fine, unlike the TS files that VLC
creates which there is no audio support.  Another
interesting thing is that VLC cannot play files created
with mplayer like above - the video is badly corrupted.

Gildas had mentioned something about support for MPEG
system headers - it doesn't appear that this addition has
helped the PS problem I had reported earlier.

I would really like to be able to interchange files
created by all of these projects, since all of them have

I would be more than happy to help troubleshoot this buy
providing sample files for comparison.

Thanks,
