Enable real CBR video for H265 encoders #109

Closed tipoman9 closed 1 year ago

Required information

Issue description

Seems like H265 encoding is always Variable Bit Rate, even when set to Constant Bit Rate. When changed to H264 CBR , it gives constant bitrate as expected. Such feature will be useful for FPV users , who require a video stream with a bitrate just below the limited radiolink bandwidth in order do get maximum possible quality.

CBR for H265 codec was added, please check if it works in new Majestic build and close the issue

I confirm it works, tested in gk7205v200 and hi3516ev300. On Ingenic T31 I had to set these params in the majestic.yaml to make it work as real CBR. video0: minqp: 10 maxqp: 45 initqp: 10
