Hi,

  • quant-i/p/b-frames
    qp range is 0 - 51. Please set in this range.

  • SliceIntraRefreshInterval
    iframeinterval is to set interval of IDR frames, and SliceIntraRefreshInterval is to set interval of I frames. generally we set IDR frame interval > I frame inteval. Such as iframeinterval=30 SliceIntraRefreshInterval=15

  • slice-header-spacing
    This is to set how many macroblocks are put in one encoded slice. There is same properties in jetson_multimedia_api sample and please refer to
    How does slice mode video encoding work for Jetson? - #14 by DaneLLL
    So the range depends on the resolution.
