1.26.4 Error while decoding frame errors

[alon]

Hello,

Here is a URL to my live IP Cam stream (please remove any white spaces, i had to add those because otherwise this post is flagged as spam)
rtsp://ipcam . zapto . org / cam / realmonitor?channel=1&subtype=0&authbasic=YWRtaW46YWRtaW4=

I am not able to get ZM to process this RTSP H264 video stream (i see nothing in the preview window) although the stream works perfectly fine in VLC. In the debug logs I'm receiving a non-stop stream of "Error while decoding frame 0" messages.

Below is a snippet from the debug output as well as all the configs and details related to my setup.

I would appreciate any help i can get to resolve this issue and at the same time help strengthen ZM.

Cheers

Here are the technical details of the stream, platform and ZM setup:
IP Cam Brand & Model - Dahua IPC-HDW2100
Stream - H264, 704X480, 15fps, VBR, Quality 4, bitrate 640, I frame interval 30
OS - Ubuntu Lucid Lynx (10.04) running on MacBook1.1 (2006)
ZM - v1.24.2
ZM Monitor config - SourceType-Remote, RTP/RTSP

ZM - v1.24.2

At least - change version to 1.26

But in fact in zm i see only frame differences... may be this help to you

POK, thanks for responding. I am using 1.24.2 because it is the distribution that i was able to pull down for Ubuntu 10.04 (Lucid Lynx) which is older - i'm using older hardware (MacBook 1.1 from 2006).
perhaps i should try to build the latest zone minder release?

In case you haven't been following the news on github, zoneminder 1.26.5 was released today.
Most importantly, this release includes RTSP fixes that should resolve the decoding frame errors some of you are experiencing.

Please upgrade your systems and let us know your results.

@knnniggett - thanks, i'll check it out and report back!
