Description

I use FFmpegFrameGrabber to process images frame by frame and push the stream to the rtmp server, but the rtmp playback delay is too high. What can I do to reduce this delay? I think I can accept it within 5 seconds

Contributor guide

Research direction
Look into FFmpeg encoding parameters for low latency streaming, such as tuning zerolatency, reducing buffer sizes, adjusting GOP size, and using faster presets. Also check if FFmpegFrameGrabber exposes these settings.
