Improving OpenCV videowritter performance in Jetson TX2

[DaneLLL]

Hi,
A topic might help:

cv2.VideoWriter[Gstreamer + Opencv] using Hardware Encoder with python code

Hi, Please try gst_out = "appsrc ! video/x-raw, format=BGR ! queue ! videoconvert ! video/x-raw,format=RGBA ! nvvidconv ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=test.mov " BGR is not supported by nvvidconv. Please use videoconvert to convert it to RGBA and then send to nvvidconv.

Not sure how cv2.VideoWriter() works, but looks like you can run the pipeline to levergage hardware encoding. Please give it a try.
