[vlc] Howto "dump raw input"

[Peter Daum]

I am struggling to get vlc to just dump the raw input data stream to a
file, something that seems to be directly supported by vlc, but I just
can't get it to work. Using vlc 0.8.6 from Debian lenny, it sometimes
works via the "Wizard", but not via the "Stream/Save" button. I also
compiled the latest version (1.0.6) with mostly the same result. So
either I fundamentally misunderstand something or this options just
doesn't work. Here's what I do:

- Choose some input, e.g. with the menu option "Media|Convert/Save".
- Click on the "Convert/Save" Button
- enter a destination file
- ignore the "Profile" option and instead
- mark the "Dump raw input" checkbox
- and finally click on "Start"

Unfortunately, instead of dumping the data to file, vlc always _plays_
the input without creating any file. It doesn't make any difference,
whether the "display the output" option is checked. Transcoding the
input data seems to work as expected (same procedure, "Dump raw input"
unchecked and some profile chosen (actually there always is a profile
chosen ...)

I also tried the following command line, that seems to be equivalent:
vlc <input stream> :demux=dump :demuxdump-file=/some/file
with the same result.

I'd really appreciate if somebody could enlighten me what's going wrong ...
