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

Typedef Documentation

typedef void(* vpx_codec_put_slice_cb_fn_t)(void *user_priv, const vpx_image_t *img, const vpx_image_rect_t *valid, const vpx_image_rect_t *update)

put slice callback prototype

This callback is invoked by the decoder to notify the application of the availability of partially decoded image data. The

Function Documentation

vpx_codec_err_t vpx_codec_register_put_slice_cb	(	vpx_codec_ctx_t *	ctx,
		vpx_codec_put_slice_cb_fn_t	cb,
		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.
