H.264/H.265 Level implementation (High Framerate)

I am not a developer (per se) and I don’t own a Jetson Toolkit, but Nvidia customer service did not know the answer to my question and they told me to post it on here. I hope I am in the right place.

Does the H.264 compression tool as implemented on the JTX1 include level 5.2 of the H.264/265 spec that has a provision for 178 fps video?

Thanks in advance…

Hi Dan,
What is the resolution in your case? Is it 4k 178fps? Level5.2 is not supported in latest release r24.2.1, but please share your usecase more clearly for our reference.

We could go as low as SD, but 720P is desired and, of course, more resolution is better. We are planning to use a USB Basler camera that has a number of resolutions and framerates available.

Hi Dan,
On TX1, the spec is 4Kp30. It is close to Level5.1 per https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels

The case 720p178fps should also run well.

Thank you. Can I specify custom resolutions, like 1080X1080? What is the hardware that performs H.264/265 encoding/decoding?

Hi Dan,
For TX1, the spec is 4kp30. It should be good for 1080x1080p30. Please refer to document for running encoding/decoding:
