GI.GstVideo.Structs.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 setFormat vmethods.

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

Arguments

:: (HasCallStack, MonadIO m)

=> VideoCodecState

state: a VideoCodecState

-> m VideoCodecState

Returns: buf

Increases the refcount of the given state by one.

videoCodecStateUnref

Arguments

:: (HasCallStack, MonadIO m)

=> VideoCodecState

state: a VideoCodecState

-> m ()

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