From 2506ad9f170ba3c21eed5dd884f51413adc51d37 Mon Sep 17 00:00:00 2001 From: Alexandre Colucci Date: Mon, 4 Apr 2011 15:08:50 +0200 Subject: [PATCH] Fix VC-1 playback with pulldown content The attached patch fixes the jerky playback of VC-1 content with pulldown. The pulldown flags were incorrectly set. They must be correct in order to display the frames with the correct timing as mentioned in the specifications: "SMPTE 421M: VC-1 Compressed Video Bitstream Format and Decoding Process". More precisely the following tables: Table 20: Progressive P picture layer bitstream for Advanced Profile Table 22: Progressive B picture layer bitstream for Advanced Profile Table 23: Progressive Skipped picture layer bitstream for Advanced Profile Table 82: Interlaced Frame I and BI picture layer bitstream for Advanced Profile Table 83: Interlaced Frame P picture layer bitstream for Advanced Profile Table 84: Interlaced Frame B picture layer bitstream for Advanced Profile Table 85: Picture Layer bitstream for Field 1 of Interlace Field Picture for Advanced Profile Signed-off-by: Michael Niedermayer --- libavcodec/vc1.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavcodec/vc1.c b/libavcodec/vc1.c index 1b77105f07..73f0cba042 100644 --- a/libavcodec/vc1.c +++ b/libavcodec/vc1.c @@ -859,7 +859,7 @@ int vc1_parse_frame_header_adv(VC1Context *v, GetBitContext* gb) v->rptfrm = get_bits(gb, 2); } else { v->tff = get_bits1(gb); - v->rptfrm = get_bits1(gb); + v->rff = get_bits1(gb); } } if(v->panscanflag) {
