Does RTSP support moving forward?

[chemi]

Hi, I am experimenting with video streaming. I have VLC 1.0.3 and accessing via RTSP to a on-demand video (it has AVI extension). It works great but when I try to move forward (30 minutes forward for example), it tries something and then after a couple of seconds it stops and closes the movie.

Is it a restriction of RTSP protocol (reading http://es.wikipedia.org/wiki/RTSP I didn't find fwd command)? Is it a restriction of AVI format?

Thanks in advance,

Chemi.

The RTSP protocol should support it. But that depends on the server.

Ok. Does VLC 1.0.3 support forward with RTSP protocol? Just trying to figure out if I have a problem with my AVI files or it is a restriction of current version then.

Thanks,

Chemi.

[Rémi Denis-Courmont]

Sure.

Any help about how to investigate why it is not working for me?
I have tested with different files using following codecs: XviD/MP3 and DivX 5/MP3. It doesn't work with any.
BTW, the time line slider, doesn't progress with regular play.

I have VLC 1.0.3 streaming VOD via RTSP on a WinXP Box and VLC 1.0.3 playing it from network from a different WinXP box.

I don't know what else to test if VLC implements RTSP with forward/backward features. Any tip?

Thanks in advance,

Chemi.

P.S.: If I open those files locally from file system instead via network, forward/backward works fine. And the time line slider moves perfectly when playing.

I activated verbosity level 2 in Message window and this is the info I get when try to move forward (it seems it gets stuck buffering at 36%). Is there any setting I can use in the server to avoid this problem?
