Thanks David for the response …
Here is additional comments for your reference,
“Tegra TX2 can encode 4K60fps H265 while Tegra TX1 did only 30fps. Now the encoder is fully accelerated by hardware, on TX1 the encoding was hybrid.”
To test that, you could use 4K@60hz video clip as source for video encoder and see the output.
Following gstreamer pipeline commands will showcase 60FPS video encode using videotestsrc as input,
(details under https://developer.nvidia.com/embedded/dlc/l4t-accerated-gstreamer-guide-27-1)
gst-launch-1.0 videotestsrc num-buffers=300 ! “video/x-raw, width=(int)3840, height=(int)2160, format=(string)I420, framerate=(fraction)60/1” ! omxh264enc ! qtmux ! filesink location=test.mp4 -v -e
Hope this helps …
