I’m looking stringent bitrate options for omx-encoder (https://developer.download.nvidia.com/embedded/L4T/r32_Release_v1.0/Docs/Accelerated_GStreamer_User_Guide.pdf):
Stringent Bitrate must be enabled along with constant bit rate (control-rate=2), two-pass CBR being enabled, and virtual buffer size being set
What are the recommendations for the v4l-encoder?
Particularly interesting is the way to determine the virtual buffer size to achieve a constant output bitrate and how it can be related to such parameters as resolution, pixel format, codec, fps, gop size. Perhaps something else can be used to select this value?
