[vlc] Dump streamed data

[Philippe De Neve]

Hi,

I want to stream a file (I used MPEG-1 .m1v and MPEG-4 .mp4) from VLC to VLC
using UDP or RTP. This works fine. The player VLC shows the clip although
the first fraction of second the display is ugly (green) but fastly
recovers. No big problem so far.
When I now want to dump this video clip to an output file I can choose
between 'raw data' or not. When I do NOT use 'dump as raw data' a file is
contructed but it's smaller than the original file (1100219<->1055432
bytes). So some bytes where forgotten?The resulting file is unplayable so I
checked the file binary with ultraedit which showed me that some (about 300)
"ff" bytes and some other stuff where appended at the beginning of the file
.They do NOT exist in the originating file. There's probably a relation with
the fact VLC is displaying the first 5 frames (or so) green.

Now I tried to dump the file as "raw data" which results in ....nothing. No
file gets created and no data gets dumped?
This dumping capability is important for me (I want to measure quality
afterwards). Can anybody tell me if this is a bug or am I doing something
very wrong?
