GstVideoCodecFrame.outputBuffer

the output #GstBuffer. Implementations should set this either directly, or by using the gstvideo.video_decoder.VideoDecoder.allocateOutputFrame or gstvideo.video_decoder.VideoDecoder.allocateOutputBuffer methods. The buffer is owned by the frame and references to the frame instead of the buffer should be kept.

struct GstVideoCodecFrame
GstBuffer* outputBuffer;
