we use the following url to push stream in gst rstp.

v4l2src device=/dev/video0 ! tee name=raw raw. ! queue ! nvvidconv ! omxh264enc ! video/x-h264,stream-format=byte-stream,alignment=au ! fpsdisplaysink video-sink=fakesink signal-fps-measurements=true text-overlay=false --gst-debug=fpsdisplaysink:6 raw. ! queue ! nvvidconv ! omxh264enc ! rtph264pay mtu=1400 name=pay0 pt=96

The program reports an error and crashes. The message is as follows：
Stream ready at rtsp://0.0.0.0:8554/video
Framerate set to : 30 at NvxVideoEncoderSetParameterNvMMLiteOpen : Block : BlockType = 8

Event_BlockError from 0BlockHevcEnc : Error code - 4

We still have this problem when we use another url.
v4l2src device=’/dev/video%d’ ! ‘video/x-raw, format=(string)YUYV, width=(int)1280, height=(int)720, pixel-aspect-ratio=(fraction)1/1, framerate=(fraction)10/1’ ! nvvidconv ! nvv4l2h264enc ! rtph264pay mtu=1400 name=pay0 pt=96

Please help to answer.
The hardware platform used is Xavier, and the system version is 32.3.1.The previous TX2 did not encounter this problem

Hi,
You may try with test-launch. Please refer to

The test command is as follows：
./test-launch ‘videotestsrc ! nvvidconv ! nvv4l2h264enc ! h264parse ! queue ! rtph264pay name=pay0 pt=96 audiotestsrc ! voaacenc ! queue ! rtpmp4apay pt=97 name=pay1’

The error message is as follows

Continuing the discussion from Error encoding with omxh264enc or nvv4l2h264enc in gstreamer:

./test-launch ‘videotestsrc ! nvvidconv ! nvv4l2h264enc ! h264parse ! queue ! rtph264pay name=pay0 pt=96 audiotestsrc ! voaacenc ! queue ! rtpmp4apay pt=97 name=pay1’

Hi,
Please clean the cache and tray agin.

nvidia@nvidia-desktop:~$ rm .cache/gstreamer-1.0/registry.aarch64.bin

If cleaning cache does not help, suggest you re-flash through SDKManager.
We have verified it on r32.3.1 and r32.4.2. Don’t observe this issue.
