I will try saving like that, maybe that file can be then thrown to NvAPI Example and HW encode to H264, we will see
I tried, and as expected it’s starting to be laggy after a second - that too much for it, and even throwing that file to example to encode with H264 gives the wrong video.
I also tried to convert my frames to Bayer as shown here, and then save it to file with H264 encoding (that way of saving cause like 1 fps drop, I can deal with that) but after that when I tried to read that file (on my PC) I get error

Btw what about that:
I by chance saved once in MPEG-4 video format and 7400 kbps, and while I could not play that file with any program (Internal stream error) - but I could read it by OpenCV again and then save it correctly (seems like my first idea), but I don’t know how I have done that. Now when I try to do the same I’m only getting MPEG-4 (Simple Profile) which is not working
. I have done that on lower resolution (640x480) so I’m not even sure if that’s really would solve my problem.
Do you know how to do that again? At last, I could check if that would be ok as well in full resolution
