Hi !

Here my configuration :
CentOS 4.4
VLC 0.9.0 snapshot 24/06/2007.
ffmpeg snapshot 25/06/2007
live555 01/07/2007
I'm working on a P4 3.00Ghz, 500MB physical memmory.

Openning a file locally works good.

I'm trying to open a RTSP stream (from a camera) via vlc. Everything going fine, the video shows up 3 secs, then freezze and error message :

Code: Select all

[00000265] ffmpeg decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

I've used that command

Code: Select all

./vlc rtsp://my_ip:1125/mpeg4/media.amp

and here is a more verbose launch

Code: Select all

[00000265] ffmpeg decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

And Hell, i can't figure out any solution.
I've tried to use --rtsp-caching, same problem.
I've search on the forum, no solutions.

I have no idea from where could come the problem.
If someone have a solution, i take it ^^ !
Thx for any answer !

I've found an alternative to my problem, i use vlc 0.8.6c.
I've build it with the same options than vlc0.9.0 and it works fine.
Really don't know from where comes the problem.
I'v compared the -vvv launch in both versions, and it was almost the same. So i fear that there is a problem with rtsp in 0.9.0.

But i have now an other problem.
I'm trying to connect on my cam with login/pass, so i've but searched on the wiki, forum, tied few solution, but no one works.

Code: Select all

./vlc rtsp://ip_to_cam/mpeg4/media.amp --rtsp-user my_user --rtsp-pwd my_pass
./vlc rtsp://user:pass@ip_to_cam/mpeg4/media.amp

Can someone give me a clue ?
Thx !

I've got exactly the same problem. 0.8.6a works great with transcoding my rtsp mpeg4 stream to wmv, in 0.9.0-svn I keep getting those "late picture skipped" errors.

I urgently need help...
