Jerome Borsboom	f56a0b02cd	avcodec/vc1: fix out-of-bounds reference pixel replication Out-of-bounds reference pixel replication should take into account the frame coding mode of the reference frame(s), not the frame coding mode of the current frame. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>	7 years ago
Jerome Borsboom	362ce2db4b	avcodec/vc1: implement interlaced out-of-bounds reference pixel replication The existing implementation did out-of-bounds reference pixel replication for progressive reference frames. In interlaced reference frames both the even and odd line on the horizontal edges need to be replicated. Fixes #3262. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>	7 years ago
Jerome Borsboom	79f8074cc4	avcodec/vc1: store color-difference reference field type The loop filter for P interlace field pictures needs the reference field type. For luma, the reference field type was already available. Store the reference field type for color-difference as well. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>	7 years ago
