STM32N6 H264 Video Encoder - Region of Interest

Hi all, we have developed a video capture application and are field-testing this right now. In order to optimize perceptual quality, we are tuning the quality parameters to find a good trade-off.

I saw in the h263encapi.h some features mentioned that are interesting to our application but could not find out if the VENC hardware actually supports it, like

  • Region of interest
  • cyclic intra refresh
  •  Video stabilization (although I fear that memory bandwidth is a limit here)

I have read the Hantro Software Integration Guide in the github repository but that does not go into detail on what is available on the STM32N6.

It seems that there has been an earlier discussion in this topic mentioning an Internal ticket number: 209269

Could we have a feature map on what the IP block actually supports and the related software documentation?

Thanks a lot 
Simon
