I am having an identical issue to this one: GRAY8 source with nvvidconv and nvv4l2h264enc produces video with wrong color format (washed out)
where my grayscale image is washed out when using hardware encoding for h264
However, the accepted answer did not work for me. I patched and recompiled nvvidconv as @DaneLLL suggested, but now my output is green instead of gray and still washed out.
Here is my pipeline:
appsrc ! nvvidconv ! nvv4l2h264enc ! video/x-h264,format=byte-stream ! h264parse ! rtspclientsink location=myserver
I’m feeding gstreamer with a grayscale mat from OpenCV, here is the video writer declaration:
writer = cv2.VideoWriter(pipeline, cv.2VideoWriter_fourcc(*'X264'), 30.0, (1920, 1080), False)
I would really like to leverage the hardware acceleration instead of using
videoconvert or converting the image to BGR with OpenCV, it is a waste of CPU cycles. Any advice would be appreciated.
