RTSP seeking implementation

[E-bola]

I have been using the new VLM feature of VLC and i simply love it
Although one thing is missing badly, you can not, so far, seek in the RTSP streams. Seeking or atleast a Fast forward function or similar is a MUST when streaming. I know MS win 2003 streaming solution supports it with their semi private RTSP solution, and pretty sure real and darwin streaming server supprots it too, so it should definately be possible.

Anyway thats my request: To be able to seek with a slider bar, as in normal palyback in vlc, when streaming in RTSP.

Somebodyt please implement it pretty please

say: pretty pretty please with a cherry on top

/me emulates a cherry

so far, vlc crashes when I try to seek within the demo videos provided with Darwin while Quicktime seems to have absolutely no problems.

So far, there's no client on linux able to seek within rtsp provided videos, it would be really great to have VLC supporting seek functionnalities, especially for thin clients and in corporate environment.

rtsp seek works fine here

I have been using vlm to serve rtsp-udp streams with vlc to vlc and seeking works. I use mpeg2 ps streams.

The dfeveloper who implmeneted seeking, did mention that not all containers was supported though, so maybe u can try some different ones to see if that gives u any success, please report back either way

Cheers E-bola

do you know where I can find more informations about the seek supported streams?

Thanks beforehand

Trial and error

Thanks but ... no...

I'm already doing that, if I ask on the forum, it's with the desesperate hope someone knows more about the subject. (are the vlc devs sometimes reading the forum?)

If someone can point me to a post, an article, a doc, a source file where I can have a look at what works and what doesn't, I'd be really gratefull.

This information has not been gathered so far.

However if I try the streams from Apple Events (hosted on QTSS), then seeking works for me. That's all I know.

http://stream.qtv.apple.com/events/sep/ ... 04_ref.mov
That one for instance

[ragoutoutou]

seems like http stream...

In fact, my problem is the following: the company I work for is about to deploy thin clients to replace ou Wintendows desktops... So far, the os choice is pending between a linux image or a xp embedded image. The problem is the company demands a video streaming framework... on the windows side, no problem, they have the mms+wmp system... on the linux side, we have nothing so far (i'm testing the fenice/dss/helix/vlc at the server side and the Cisco OSSVP/Helix Player/MPlayer/Nemesi at the client side).

Has anybody been able to find a solution of VLC seek problem. Am facing the same issue. Am using Darwing Server version 6.0.3 and VLC client version 1.1.3. Have tested the same server with Quicktime on Windows and Totem on Fedora and seeking works perfectly for both.

[Sébastien Escudier]

Seeking works for me with vlc client connecting to vlc server or live555 server.
Don't know about the others one.
Do you have logs of vlc when you send a seek request ?

Following is the output of vlc with -v switch:

please use -vv
there should be live555 rtsp communication.

The output log file was too large to post here. Have uploaded to following URL:

Any help here would be appreciated.

hi,

i have a similiar problem posted here: viewtopic.php?f=4&t=84108&start=0

have you found a working solution?!

please let me know, thx

[jahanzeb]

I have tested the seek issue with the Developer version of Wowza Media Server V2.1.2 and VLC 1.1.5. The seeking is working properly. But for Darwin streaming server haven't found a solution yet.
