Is there some limitation about the number of streams to encode to H264 or H265 at the same time?
If I use a small resolution, can I increase the number of streams?
Thank you very much!

Dear @user77640,
Do you mean if two encoding operations performed in parallel on a single NVENC hardware engine?

Hi @SivaRamaKrishnaNV:
Yes, for example, I have 4 cameras, and I want to encode the streams from the cameras to H264 or H265 at the same time with NVENC hardware engine on Xavier.
1 I want to know how many streams does NVENC can support?
2 If I use a lower resolution, or lower fps, can NVENC support more streams?
3 It are two NVENC hardware engines, does Drive OS software support more than two h264 encode instance at the same time if I use lower resolution? How to do it?
Thank you very much.

Dear @user77640,
There is no limitation on numbers of streams that can be launched on a NVENC engine. We have tested up to 8 streams with out any issue.
