[vlc] Re: VLC MPEG2 streaming reception

Hi again,

Looking at the file I uploaded (axis-stream.dmp) using the above command, I
notice that the video is corrupted whichever player I use, ie the file
contains "bad" data.

I created a new stream dump using mplayer (mplayer -dumpvideo
sdp://my-file.sdp). The new file plays perfectly in mplayer and vlc. I have
uploaded this new file to the server with the name
"axis-es-windows-mplayer.mpg" (stream from the axis server saved using
mplayer on a windows platform).

The interesting thing here is that when I stream this new file using vlc
(vlc -vvv --extraintf logger axis-es-windows-mplayer.mpg --loop --sout
#rtp{dst=228.96.1.1,sdp=file://guide5.sdp} ), I can receive it fine using
mplayer (mplayer sdp://guide5.sdp) but if i try to receive it using vlc
(vlc -vvv --extraintf logger udp:@228.96.1.1) then I see video corruption.

[ Again, the command "vlc guide5.sdp" will not show the video (I still get
the "ps warning: garbage at input" messages) but this is a different issue.
]

I would much appreciate if you could take a look at the file to see if you
get the same behaviour as I do. I have tried streaming other types of file
(MPEG PES, AVI) and this works fine using the sdp file. It looks to be an
issue specific to elementary streams.

regs and thanx
Robert
