Christophe Gisquet	05da586fef	dv: move inverse weight tables to decoder The encoder has its own tables and does not access the idct_factor member of the DVVideoContext structure. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	6fe02d25ee	dv: fix weight table for 2x4x8 transform The coefficients must be in the appropriate zigzag scan order. Also fix their values at the same time, as they were pretty wrong. Fixes ticket #2970. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	1086f09da3	dv: more precise weight table for 8x8 It is derived from the actual equations of the specs. In particular, it is closer to the inverse of what the encoder uses. fate tests accordingly updated. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	80b29c2d0c	dv: use smaller type for weight tables Reviewed-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Anton Khirnov	a839dbb94e	dvenc: print allowed profiles if the video doesn't conform to any of them.	13 years ago
Reimar Döffinger	31ff2cb266	DV: detect another case of broken DV files. See trac issue #217. Only the dsf field seems to be used to distinguish between PAL and NTSC. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	feda266db5	DV: check coded_width/height instead of width/height. This makes the workaround also work with lowres. Fixes issue #633. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Michael Niedermayer	2560d3b648	dv: Fix streamcopy input. Fixes Ticket1042 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Reimar Döffinger	8fbf825ecc	DV: Use profile[1] detection hack only for stype 0. The two samples both have stype 0. Without this extra check, the code breaks 4:2:2 dvsd (stype 4), since that has the same resolution. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Michael Niedermayer	63d2cfd142	dvdec: Fix dvsd profile[1] detection. Fixes Ticket159 If someone knows of a cleaner way to detect this, patch is welcome. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Niobos	e2f0214a0b	Fix a yuv420p sample that was incorrectly detected as yuv411p (576i50 25Mbps 4:1:1 special case was wrong). Fixes issue2211 Patch by Niobos, niobos dest-unreach be Originally committed as revision 25269 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Baptiste Coudurier	348a3237cc	In dv decoder, use the expected aspect ratio logic, like other decoders do, following width/height = par/dar. Originally committed as revision 25231 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Charles Yates	10a693b568	fix sar for dvcpro hd, patch by Charles Yates, charles dot yates at gmail dot com Originally committed as revision 20291 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	c76911bd65	Split parts of dvdata.h into dvdata.c, this ensures that things like work_chunks_* and dv_idct_factor_* variables appear only once in the binary instead of 3 times. Saves 3264 bytes in .rodata and 312416 bytes in .bss on x86_64. Originally committed as revision 20246 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
