Struct gstreamer_video::video_codec_state::VideoCodecState[−][src]

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

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 [crate::VideoDecoder::set_output_state()] (XXX: @-reference does not belong to VideoCodecState!) or [crate::VideoEncoder::set_output_state()] (XXX: @-reference does not belong to VideoCodecState!) methods.
