Details

class GstVideo.VideoCodecState

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 GstVideo.VideoDecoder.set_output_state() or GstVideo.VideoEncoder.set_output_state() methods.

ref()

Returns:

buf

Return type:

GstVideo.VideoCodecState

Increases the refcount of the given state by one.

unref()

Decreases the refcount of the state. If the refcount reaches 0, the state will be freed.
