Detailed Description

The following functions are required to be implemented for all decoders that advertise the VPX_CODEC_CAP_PUT_SLICE capability. Calling these functions for codecs that don't advertise this capability will result in an error code being returned, usually VPX_CODEC_ERROR

		void *	user_priv
	)

Register for notification of slice completion.

Registers a given function to be called when a decoded slice is available.

Parameters:

[in]	ctx	Pointer to this instance's context
[in]	cb	Pointer to the callback function
[in]	user_priv	User's private data

Return values:

	VPX_CODEC_OK	Callback successfully registered.
	VPX_CODEC_ERROR	Decoder context not initialized, or algorithm not capable of posting slice completion.
