I am using streaming gst pipeline from video 0-7 running simulatenously , but after sometime my gstreamer pipeline crashes.
I am using ubuntu 20.04
gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! videorate max-rate=20 ! x264enc ! mpegtsmux ! tsparse ! rtpmp2tpay ! udpsink host=192.168.0.107 port=5000
the above is the pipeline i am using
Hi, it would be a good idea to test on something more recent, a lot have happen in nearly 5 years. One way forward is to use containers (flatpak, docker,etc) to avoid upgrading without a reason, though 20.04 is very old.
When you report a crash, you should share a crash backtrace, catched with gdb or reported by coredumpctl (systemd feature enable on recent OS). If by crash you instead mean a runtime error, you should share some logs of the error. You can increase gstreamer logging a little, with env GST_DEBUG=2 as a good starting point of the discussion.
Hi,
we want to run seven channels for streaming and apprently the pipeline had crashed, the pipeline is same as what i have given above with the video device varying from 0-6.
below is the log for coredumpctl which was caught by the kernel,

also please note that the same v4l2src when replaced with videotestsrc works fine without any issue and streams all the 7 channels together.
Please do help us solve this

Mind following the instructions on the last line of your log, then when gdb is connected, you will be able to produce a full backtrace with:
gdb> thread apply all bt
Again, make sure to test with recent version of GStreamer, as this crash may have been fixed a long time ago. There is little to no information in the current trace unfortunatly. It is also unclear which drivers is used behind the scene.
p.s. use tripple back tick to start/end a verbatime log. I’ve edited your post to make it readable.
SC0710 is Elgato PCI capture card ? Is that the reversed engineered driver ?
Yes it is a yuan tech 4 channel hdmi and 4 channel pal capture card driver
