dmabuf problem when using v4l2h264dec #3519

Closed igormq closed 4 years ago

igormq commented 4 years ago

Hi,

I am having some weird problems on running the v4l2h264dec (Gstreamer 1.14.5) on RPI 4 (Raspbian Buster). First the following command runs successfully for over an hour:

gst-launch-1.0 rtspsrc location="rtsp://my/path" short-header=TRUE ! rtpjitterbuffer ! rtph264depay ! h264parse ! v4l2h264dec capture-io-mode=4 ! videoconvert ! videoscale ! videorate ! video/x-raw,framerate=5/1 ! v4l2h264enc capture-io-mode=4 output-io-mode=5 extra-controls="encode,h264_i_frame_period=10,video_bitrate_mode=0,h264_level=11" ! h264parse ! video/x-h264,format=avc,alignment=au

I have already investigated a little bit, and by enabling the debug mode on the bcm2835-codec, the following message appeared in dmesg after an hour running the command above:

vc_sm_cma_vchi_rx_ack: received response 65537, throw away...

Curiously, I got more than 2k+ vcsm-cma devices attached in dma_buf by running the following command when the gstreamer command above failed:

sudo cat /sys/kernel/debug/dma_buf/bufinfo | grep attached

Is it normal?

I did not see any CMA memory leak (by running cat /proc/meminfo |grep Cma) and by running lsmod | grep ^videobuf2_dma it looked ok (videobuf2_dma_contig 20480 46 bcm2835_codec)

Then, after restart the gstreamer pipeline above (using GST_DEBUG=5), I am getting the following "error":

because the v4l2h264dec was not able to flush everything:

0:01:09.617667940   441   0xf681a0 DEBUG         v4l2bufferpool gstv4l2bufferpool.c:960:gst_v4l2_buffer_pool_flush_start:<v4l2h264dec0:pool:sink> start flushing

Can you guys help me here?

Thanks in advance!
