imx8: couldn't launch h264 gstreamer pipeline after killing gstreamer multiple times.

When one repeatedly launches gstreamer using h264 vpudec and then terminating it with killall it leads to situation where pipeline stops working. From log below it looks like that it doesn't properly free decoder and they run out. I couldn't replicate this behaviour by using gst-launch -e and properly termination it with ctrl-c sending EOS.


gst-launch-1.0: ../../source/h264high/h264hwd_asic.c:1009: H264RunAsic: Assertio

As side note how one builds h264 encoder? It could lead to easier example of videotestsrc ! encode h264 ! vpudec ! glimagesink

test scripts are


gst-launch-1.0 ...(rtsp h264 stream from camera) ! vpudec ! glimagesink


for ì in `seq 1 100`; do

sh test &

sleep 3

killall gst-launch-1.0
