Hi,

On quadro rtx 4000, does nvv4l2decoder support decoding of h264file with YUV4:2:2 chroma subsampling?

Pipeline is:

gst-launch-1.0 filesrc location = Samples_yuv422.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvideoconvert ! nveglglessink

This pipeline simply halts at pre-rolliong without throwing any error

Could you please share the video if possible or how about the video codec format?

Hi,
As you can find in https://developer.nvidia.com/nvidia-video-codec-sdk, GPU hardware does not support YUV4:2:2 foramt.

Thanks!
