following calculations for max-picture-sizes value:
- For IPPPP mode, use ” max-picture-sizes
<3*target_bitrate_Kbps/fps, target_bitrate_Kbps/fps, 0>
For example: 90 Mb/s, 60 fps, use max-picture-sizes=<4500, 1500, 0>
- For I only mode, use ” max-picture-sizes
<target_bitrate_Kbps/fps, 0, 0>
For example: 90 Mb/s, 60 fps, use max-picture-sizes=<1500, 0, 0>
