We are currently evaluating a new project and its feasibility on Jetson NX.
What we want to achieve is encoding 2 video streams Monochrome 2k (2464 x 2056 pixels) @ 60 FPS using the Xavier NX, using XImea cameras (PCI-express). We would prefer to have either VP or HEVC h265 encoding.
We want to achieve lossless compression on those streams.
Is it possible to achieve such performances using this platform?
As Ximea cameras can use PCIExpress DMA to forward captures frames, is it possible for nvenc to read frames without any copy for encoding? AFAIK, the memory switch fabric seems to be able to handle this use case.
If frames provided by the camera need debayering or monochrome conversion, is this can be handled by NVENC?
On Jetpack 4.6(r32.6.1), we support YUV444 lossless encoding in h265. And is able to achieve two-instance 2464x2056p60 encoding on Xavier. You may consider to use Xavier if 2464x2056p60 is a hard requirement.
On Xavier NX, two-instance 2464x2056p30 encoding looks fine.
