Hi,
I have the following scenario :
v4l2src -> crop -> resize ->
---> process1 (with opencv)
---> rtsp server
In order to do the split, I'm using shmsink and shmsrc as follows:
preprocessing:
GST_DEBUG=1 gst-launch-1.0 v4l2src device=/dev/video0 !
video/x-raw,width=1920, height=1080,format=UYVY ! videocrop top=0 left=60
right=60 bottom=585 ! videoscale ! videorate !
video/x-raw,width=640,height=480,format=UYVY,framerate=15/1 ! shmsink
socket-path=/tmp/video-sock shm-size=10000000 wait-for-connection=false
sync=false
process1:
shmsrc socket-path=/tmp/video-sock is-live=true !
video/x-raw,width=640,height=480,format=UYVY,framerate=15/1 ! videoconvert !
appsink
RTSP server:
./test_launch "shmsrc socket-path=/tmp/video-sock is-live=true
do-timestamp=true name=video-sock ! video/x-raw,
format=UYVY,width=640,height=480,framerate=15/1 ! videoscale ! videorate !
videoconvert ! video/x-raw,width=640,height=480,format=I420,framerate=15/1 !
omxh264enc ! rtph264pay name=pay0 pt=96"
The pipeline seems to work, but every once in a while I get the following
error:
gst-launch-1.0: shmpipe.c:873: sp_shmbuf_dec: Assertion `had_client'
failed../gstreamer_preprocessing_pipeline_runner.sh: line 2: 69 Aborted
(core dumped) GST_DEBUG=1 gst-launch-1.0 v4l2src device=/dev/video0 !

video/x-raw,width=640,height=480,format=UYVY,framerate=15/1 ! shmsink
socket-path=/tmp/video-sock shm-size=10000000 wait-for-connection=false
sync=false
The platform is Tegra TX2.
Running Ubuntu 16.04 with Docker
Any thought why this happens?
Thanks
