Struct gstreamer_video::video_codec_state::VideoCodecState

pub struct VideoCodecState<'a, T: VideoCodecStateContext<'a>> { /* private fields */ }

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 set_format vmethods.

Decoders and encoders can set the downstream state, by using the VideoDecoderExtManual::set_output_state() or VideoEncoderExtManual::set_output_state() methods.
