◆ ff_mpv_alloc_pic_pool()

struct AVRefStructPool* ff_mpv_alloc_pic_pool ( int init_progress )

Allocate a pool of MPVPictures.

		MPVWorkPicture *	pic,
		ScratchpadContext *	sc,
		BufferPoolContext *	pools,
		int	mb_height
	)

Allocate an MPVPicture's accessories (but not the AVFrame's buffer itself) and set the MPVWorkPicture's fields.

◆ ff_mpv_pic_check_linesize()

int ff_mpv_pic_check_linesize	(	void *	logctx,

Check that the linesizes of an AVFrame are consistent with the requirements of mpegvideo.

FIXME: There should be no need for this function. mpegvideo should be made to work with changing linesizes.
