I'm facing an issue with my gstreamer pipeline application on a iMX6Q based board. When I start to record the video input into a file, after a randomly duration, the pipeline freezes a few seconds on the main display before to play again. This phenomenon can occur several times for the same pipeline. The recorded video contain as many "jumps" as freezes that occur.
I have the same issue with a gst-launch build pipeline :
gst-launch-1.0 imxv4l2videosrc ! imxvideoconvert_ipu ! tee name=t t. ! queue ! imxipuvideosink t. ! queue ! vpuenc_h264 bitrate=20000 quant=0 ! matroskamux ! filesink async=true location=/home/root/exam/noname.mp4
I have tried with imxvpuenc_h264 with same result.
So I have tried to add DEBUG outputs and add an timeoverlay to catch timestamp, so the issue has occured at 14, 24, and 44.077 second and below the associated log file : enter gst log
Here is another output that occurs only once but I've never catched it again, but I have noticed that a each "freed block" occurence, the pipeline unfreezes...

I hope that someone could help me. Have a nice day.
EDIT 1 : On the bus, there is no message related to state changed when freeze happens, neither other message...
