Help converting RTSP stream on AVI202Z [SOLVED]

Posted: Thu Apr 10, 2008 2:30 pm

Hi all, i'm now trying another different model, an Avtech AVI202Z.

It supports MPEG4/MJPEG RTSP streaming, so i'm trying to convert the RTSP stream to rawvideo to use it with Zoneminder.

I'm trying to decode the RSTP stream with ffmpeg without success.

I can succesfully view the RTSP stream with MPlayer on Windows, and also i can succesfully decode the RTSP stream with MPlayer on Linux (don't mind the X11 error). See output:

Hi guys,
i solved the problem using openRTSP + ffmpeg + vloopback + vpipe.

I piped them all and here is the command:

Code: Select all

/usr/src/live/testProgs/openRTSP -c -d 60 -t -v -u admin admin rtsp://192.168.1.221/live/mjpeg | ffmpeg -f mjpeg -i - -f rawvideo -pix_fmt rgb24 - | ./vpipe -f rgb -i 0
The openRTSP gets the rtp stream, using TCP connection (with UDP i had problems), reconnecting every 60 seconds.
It pipes the output to ffmpeg, that converts the mjpeg to rawvideo/rgb.
It pipes then all to vpipe, so i can catch the final output from Zoneminder from the /dev/video1 device.

Plese refer to this post to setup the vloopback and vpipe tools: http://www.zoneminder.com/forums/viewtopic.php?t=10766.

I hope this will be of help to anyone trying to use RDSP with ZoneMinder.

Good luck,
aNt1X

Thanks for this. Native RTSP support is progressing in ZM and should be in the next maor release.

i have been trying to openrtsp + ffmpeg + vloopback + vpipe for 3 days and hold no success yet.
everything "looks" like it's working, but i still get no video feed on the loopback device. if i try to cat /dev/video1 it just stays there and shows nothing (on real capture cards, i see alot of gibberish on the screen when doing the same)

im running ubuntu 7.10

anyone else tested this / had this problem?

i'm using it successfully on Ubuntu 7.10.

is vloopback module modprobed successfully? i had to modprobe the videodev module too, if i remember correctly, before insomodding vloopback.

are the permissions ok on video1 and video0 devices ?

are you sure ffmpeg is working? i had to recompile it from svn repository to make sure i had the latest version. i had problems using the ffmpeg version included in ubuntu 7.10 with an older ipcam.

first of all try to use a file as output for ffmpeg: if ffmpeg is working ok using a file as an output, then it should pipe correctly to vpipe.

if ffmpeg is not ok, then you should check various ffmpeg and openrtsp parameters.

regards,
