MuxerVideoSink Class Reference

Print sink that writes each frame it receives to a Muxer's video track via addVideoFrame(), determining a real isKeyFrame value instead of relying on that method's isKeyFrame=true default - via isH264KeyFrame() (Video.h) when the Muxer's video track is VideoFormat::H264, otherwise always true (correct for e.g. MJPEG, where every frame is independently decodable).

Detailed Description

Print sink that writes each frame it receives to a Muxer's video track via addVideoFrame(), determining a real isKeyFrame value instead of relying on that method's isKeyFrame=true default - via isH264KeyFrame() (Video.h) when the Muxer's video track is VideoFormat::H264, otherwise always true (correct for e.g. MJPEG, where every frame is independently decodable).

Meant as the setOutput() target for a VideoEncoder whose write() would otherwise stream straight to the Muxer's own generic, format-dispatching write() (which has no isKeyFrame parameter at all) - or for any other already-encoded-frame producer that only has a plain Print to write to.
