@Generated("io.github.jwharm.JavaGI")
public class VideoCodecState
extends ProxyInstance

Structure representing the state of an incoming or outgoing video stream for encoders and decoders.

Decoders and encoders will receive such a state through their respective setFormat vmethods.

Decoders and encoders can set the downstream state, by using the gst_video_decoder_set_output_state() or gst_video_encoder_set_output_state() methods.
