rtpjpegdepay copy_into_unchecked error

[Álvaro López López]

Hi everyone,

I am developing an application involving streaming with some IP cameras which send MJPEG video through the GStreamer pipeline.
I have installed the following packages:

- gnonlin-0.10.17
- gst-ffmpeg-0.10.11
- gst-plugins-base-0.10.36
- gst-plugins-good-0.10.31
- gstreamer-0.10.36

I am connecting to the cameras using pipelines initialized with  gst_parse_launch such as:

rtspsrc ! queue ! rtpjpegdepay ! jpegdec ! xvimagesink
rtspsrc ! rtpjpegdepay ! jpegdec ! xvimagesink

rtspsrc ! queue ! rtpjpegdepay ! ffdec_mjpeg ! xvimagesink
rtspsrc ! rtpjpegdepay ! ffdec_mjpeg ! xvimagesink

rtspsrc ! rtpjpegdepay ! ffdec_mjpeg ! ffmpegcolorspace ! xvimagesink

Also, the latency of the rtspsrc is set to 0.

However, I am experiencing too many segmentation faults in the rtpjpegdepay component. This is the GDB backtrace:

Is there anything I could do? Or is it just an unresolved bug?

Thanks in advance,

Alvaro
