Hello Devs,
I have been trying to run this gstreamer pipeline on BBAI-64. The pipeline works fine with avdec_h264 however, it doesn’t with v4l2h264dec
GST_DEBUG="v4l2*:8" gst-launch-1.0 rtspsrc location=rtsp://192.168.0.10:8554/st1 latency=1000 buffer-mode=none ! rtph264depay ! h264parse ! queue ! v4l2h264dec capture-io-mode=4 ! videoconvert ! fakevideosink
The same pipeline works fine with a file source
GST_DEBUG="v4l2*:8" gst-launch-1.0 filesrc location=video1_1280_768.h264 ! h264parse ! queue ! v4l2h264dec capture-io-mode=4 ! videoconvert ! video/x-raw,format=NV12 ! fakevideosink
I have tried different capture modes as well different latency. It gets stuck at Redistribute latency...

I am using TI-SDK 10.0 (Thanks to @jiance.zahng ). However, I had a similar problem with SDK 8.6 and 8.2 where v4l2h264dec was not able to allocate memory.
Please guide if you have any idea how this can be rolled.
Thank you
