Hi guys!
I am using VLC media player 1.1.3 in WinXP sp3.
I am able to connect and view a video network stream (rtsp://...); it simply works!

Now I'd like to dump the network stream (as it is, without transcoding) to a file.
I can record it pressing the record button or shift+r keys, but I cannot dump it!!!
I have tried to start vlc this way:
vlc rtsp://blablabla --demux=dump --demuxdump-file=filename.avi
and then I pressed shift+d but nothing happens (and nothing appears in messages with max verbosity). Obviously no file is created.

1) what is the diffrence between recording (using record button or shift+r) and dumping to a file (using shift+d, when it works...)?

2) How do I set the name prefix format for recorded files (what is the command line option?). The default is vlc-record-[date-time]___[stream title].[extension], is it possible to change it?

3) when I record the stream, the recorded file "appears" in destination directory after several seconds (even if I refresh directory view)... why? Is it possible to have it immediately dumped on disk? (maybe I should set a buffer size?)

4) Maybe in future I will need to transcode the stream before recording/dumping it; is it possible to configure a "transcoding set" (codec, framerate, ...) (maybe with a command line option) to be applied to record button action? (I know yet how to use sout option)

Thanks very much in advance for any answer!!!

(VideolanClient is magic!!! )

1) umping happens at the demuxer stage, recording happens after that
2) not possible simply
3) because it waits for a nice time to start (I-frame)
4) you cannot. use the transcoding wizard.

Thanks!
