GI.GstVideo.Structs.VideoCodecState
Description
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
gst_video_decoder_set_output_state() or
gst_video_encoder_set_output_state() methods.
- newtype VideoCodecState = VideoCodecState (ForeignPtr VideoCodecState)

- data VideoCodecStateUnrefMethodInfo
- videoCodecStateUnref :: MonadIO m => VideoCodecState -> m ()
- videoCodecStateReadCaps :: VideoCodecState -> IO Caps
- videoCodecStateReadCodecData :: VideoCodecState -> IO Buffer
