Agreed. On L4T this is provided by nvidia-l4t-kernel-headers, but on the HOS side there is no such equivalent yet. If this patch series moves forward, I will integrate the relevant bits in libnx and get rid of those headers. As for the hardware definitions (in the following patch), I think they should be put in nv-codec-headers. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
