Michael Niedermayer	728214992e	vc1dec: Remove interlaced warning Also add a note about the feature in the changelog. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	28243b0d35	vc1dec: Redesign the intensity compensation Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	b0696e947f	vc1: Reindent INIT_LUT(), align backslashes Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	6ce2c3106d	vc1: Make INIT_LUT() self contained Move the local variables it uses into the macro, enclosing them in a do {} while (0) scope. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Michael Niedermayer	05f4c05061	vc1dec: remove interlaced warning While not yet bugfree, the warning is IMHO no longer appropriate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	782ebd6118	vc1dec: redesign the intensity compensation The existing implementation had little to do with VC1. This could be implemented by adjusting the reference frames ithemselfs but that would make frame multi-threading difficult. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Mashiat Sarker Shakkhar	5d2be71b9e	vc1: Use codec ID from AVCodecContext while parsing frame header This fixes a segfault with samples that I have (both of them MPEG-TS). Looks like avctx->codec is not being set during parsing. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	35a35d49d2	Double motion vector range for HPEL interlaced picture in proper place The existing code is not in the right place and it should cover both interlaced frame and field pictures. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago

Reimar Döffinger	0f95270afe	VC1: Fix skiploopfilter=all. It is currently only handled in the parser code for WMV/ASF style header, but not the one used in the bytestream format used when muxed into MPEG-TS as on e.g. BluRay. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Diego Biurrun	3c715383ea	vc1: Move init code shared between decoder and parser to common code file. This fixes standalone compilation of the VC-1 parser.	13 years ago

Hendrik Leppkes	feaa40020b	vc1: always read the bfraction element for interlaced fields Previously, it would not be read if refdist_flag was not set, however according to the spec and the reference decoder, it should always be read. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Hendrik Leppkes	7662a532fb	vc1: don't read the interpfrm and bfraction elements for interlaced frames This matches the spec as well as the reference decoder, and fixes a bug with interlaced frame decoding. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago

Michael Niedermayer	4fd5e7639b	vc1: Fix pic_header_flag=0 (SA10143.vc1) Bug introduced in: commit `4509be3d2f` Author: Michael Niedermayer <michaelni@gmx.at> Date: Tue Oct 11 11:56:42 2011 +0200 vc1: reset interlaced variables, prevent another bunch of crashes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Kostya Shishkov	42feaf4070	vc1: explicitly zero interlaced mode coding variables for progressive mode Both v->fcm and v->field_mode are used in common code, now they won't be reset for progressive frame after interlaced one causing writing past the frame end for example. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Michael Niedermayer	7b5c03064d	vc1: enable interlaced p fields again, they seem no longer to crash with out of array writes Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	a538e0f9a0	vc1: loose one line difference to qatar. This should make no functional difference. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alberto Delmás	d2f119a1f2	VC1: Support dynamic dimension changes Fixes SA00072, SA00073, SA10150, SA10151, Issue2076 Improves SA10153 Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
John Stebbins	0d802ac54e	vc1: fix VC-1 Pulldown handling. Pulldown flags are being set incorrectly and AVFrame->repeat_pict is not being set. Also, skipped frames exit header parsing too early and do not set pulldown flags appropriately. Ticks_per_frame needs to be set and time_base adjusted so player can extend frame duration by a field time. This fixes problems encountered when attempting to transcode HD-DVD EVOB files with HandBrake. Also makes these files play smoothly in avplay. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
