attribute_deprecated int av_vsrc_buffer_add_video_buffer_ref	(	AVFilterContext *	buffer_src,
		AVFilterBufferRef *	picref,
		int	flags
	)

Add video buffer data in picref to buffer_src.

Parameters:

	buffer_src	pointer to a buffer source context
	flags	a combination of AV_VSRC_BUF_FLAG_* flags

Returns:

>= 0 in case of success, a negative AVERROR code in case of failure

Deprecated:

use av_buffersrc_add_ref() instead.

attribute_deprecated unsigned av_vsrc_buffer_get_nb_failed_requests

(

buffer_src

)

Get the number of failed requests.

A failed request is when the request_frame method is called while no frame is present in the buffer. The number is reset when a frame is added.

Deprecated:

use av_buffersrc_get_nb_failed_requests() instead.
