I was referred here after initially posting this issue on the Frigate hub. They provided help to get me to correct my ffmpeg input args to pass the RTSP stream from Nest-RTSP over UDP, but it seems there is an issue with go2rtc not recog...
input_thread_t *input = (input_thread_t *)obj; return input_ControlPushHelper( input, INPUT_CONTROL_SET_RATE, &newval ); } 让输入时钟受到速率的影响 输入时钟影响整个处理过程。为了使其受播放速度的影响,我们要查看src/input/clock.c文件。
