Bug ID: 745964
Summary: decoding failure for h264 over rtsp
Classification: Platform
Product: GStreamer
Version: 0.10.x
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: don't know
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: jspurny at seznam.cz
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
Linux Debian 7.4, 64bit, gstreamer 0.10.36
I have a program on remote server which reads stream from many cameras and it
worked just fine until now - we added 4 new cameras (new model) and gstreamer
pipeline for that camera model works fine for a few minutes (2-30) and then it
suddenly stops and starts consuming 100% CPU. Other camera's (different models)
pipelines are fine.
I'm able to reproduce it from commandline using this pipeline (executed on the
server):
$ GST_DEBUG=3 gst-launch rtspsrc location=rtsp://XX:YY ! decodebin ! fakesink
The stream is h264, 352x288, ~12fps
It's very unpredictable and when I try to reproduce it, it never does the same
thing twice. But here is list of all clues that I was able to get:
1) it never happens immediately. On some cameras, it happens sooner
(2-5minutes), on others it take days to manifest
2) in log there is allways this message:
ffmpeg :0:: decode_slice_header error
3) after this error message, it looks fine for 2-3 minutes, and then the
stream stops and gst-launch process starts consuming 100% CPU (it was ~1%
before)
I was not able to reproduce this problem on my desktop using the same
gst-launch pipeline (I'm able to acces the cameras via VPN). On my dektop I
have debian 6, 64bit, gstreamer 0.10.30 - but with manually rebuilded
gst-plugin-ffmpeg using it's own copy of ffmpeg.
Here are some examples from the logs before the problem starts (I do not post
one log, as it is allways different) which I think may be relevant:
