IMX8QXP video streaming causing VPU Decoder Error in decodebin

gravity_one — Wed, 13 Jan 2021 06:41:21 GMT

There are two board, Board1 for video multicast:

gst-launch-1.0 rtspsrc location=rtsp://10.8.8.104:8554/test latency=100 ! rtph264depay ! video/x-h264, stream-format=byte-stream ! rtph264pay ! udpsink multicast-iface="wave-data" host=ff02::1 port=1234

Board2 for video receiving:

gst-launch-1.0 -e udpsrc address=ff02::1 port=1234 ! application/x-rtp,payload=96 ! rtph264depay ! decodebin ! videoconvert ! autovideosink

And there is error on Board2:

[ 1339.312516] [VPU Decoder] firmware version is 1.5.6 [ 1340.099164] [VPU Decoder] ctx[0] amount inconsistent between input(24) and output(0)

Tried this on board2, still the same VPU Decoder error:

gst-launch-1.0 -e udpsrc address=ff02::1 port=1234 ! application/x-rtp,payload=96 ! rtpjitterbuffer latency=100 ! queue max-size-buffers=0 ! rtph264depay ! decodebin ! videoconvert ! autovideosink

BSP Version:

Hi grayli_wang

L4.14.98 is very old version and not more supported, recommended to try latest

Linux L5.4.70_2.3.0
https://source.codeaurora.org/external/imx/linux-imx/tree/?h=imx_5.4.70_2.3.0
