Anton Khirnov	7203bb6a59	lavc/dv.h: move encoder/decoder-specific code to a new header dv.h is also used by libavformat, so avoid exposing encoder/decoder code to it.	2 years ago
Anton Khirnov	828ec6ef43	lavc/dvenc: stop using DVVideoContext Move the parts of it used by the encoder into a new DVEncContext and remove DVVideoContext.	2 years ago
Anton Khirnov	69bad628ec	lavc/dv: do not pass DVVideoContext to dv_calculate_mb_xy() Pass the two variables needed from it directly. This is done in preparation to splitting DVVideoContext.	2 years ago
Anton Khirnov	91c51dac6d	lavc/dv: do not pass DVVideoContext to ff_dv_init_dynamic_tables() It only needs work_chunks from it, so pass that directly. This is done in preparation to splitting DVVideoContext.	2 years ago
Anton Khirnov	d1ba5d883e	lavc/dv: remove ff_dvvideo_init() The function contains only two assignments, setting DVVideoContext.avctx and AVCodecContext.chroma_sample_location. However, the decoder does not use the former, and the encoder should not be setting the latter. Therefore move the first assignment to dvenc and the second to dvdec. Make the encoder warn if the user-signalled chroma sample location does not match the supported one, and return an error on higher compliance levels.	2 years ago
Andreas Rheinhardt	597dc96736	avcodec/dvdec: Constify slice threads' ptr to main context Modifying the main context from a slice thread is (usually) a data race, so it must not happen. So only use a pointer to const to access the main context. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	3524e82a08	avcodec/dv: Remove unnecessary header Forgotten in `6d484671ec`. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	6d484671ec	avcodec/dv: Don't initialize RL VLC for encoder Said RL VLC is only used by the decoder, ergo don't initialize it for the encoder and move the whole code and the RL VLC table itself to dvdec.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Baptiste Coudurier	a1403032c8	avcodec/dvenc: support encoding dvcprohd	5 years ago
Baptiste Coudurier	004ebd4b37	avcodec/dvdec: correctly decode bottom mb row in 1080i field mode	5 years ago
Michael Niedermayer	fea7bc9e7b	avcodec/dvenc: Support adjusting the quantizer deadzone Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Diego Biurrun	2ec9fa5ec6	idct: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago
Diego Biurrun	de452e5037	pixblockdsp: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "stride" everywhere.	8 years ago
Diego Biurrun	b7f98659f2	Remove unnecessary get_bits.h #includes	9 years ago
Vittorio Giovara	cab63a8b59	dv: Mark internal frame reference as const Silence a warning due to frame assignment in dvenc. All uses of the reference in dvdec are read only, except the ones in the main decoding function, so use the frame pointer directly there.	9 years ago
Christophe Gisquet	4fa772acbb	dv: increase VLC reading bits to 10 This also requires a bump in the table size of bit patterns to 1664. From 356 to 348 cycles. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
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
Gabriel Dume	ee0ebd3c14	dv: K&R formatting cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	10 years ago
Michael Niedermayer	305f72aee7	avcodec: Change get_pixels() to ptrdiff_t linesize Found-by: ubitux Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Diego Biurrun	2d60444331	dsputil: Split motion estimation compare bits off into their own context	11 years ago
Anton Khirnov	f6ee61fb05	lavc: export DV profile API used by muxer/demuxer as public	11 years ago
Anton Khirnov	650dee63c8	dv: get rid of global non-const tables Instead, store them in the context and compute on each parameter change.	11 years ago
Anton Khirnov	d4f1188d1a	dv: use AVFrame API properly	11 years ago
Diego Biurrun	3cbe112653	dv: Split DV data table declarations into their own header This is necessary to avoid target config settings bleeding into the host compilation process with hardcoded tables and the DV VLC tables no longer present as static tables in a header file.	11 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Diego Biurrun	520c1ec699	dv: Split profile handling code into a separate file.	13 years ago

Anton Khirnov	242c73a0fd	lavc: use avpriv_ prefix for some dv symbols used in lavf. Specifically, ff_dv_frame_profile and ff_dv_codec_profile.	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
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
Reimar Döffinger	10249a5f31	Split VLC-related tables out of dvdata.h to make it easier to add support for hard-coding tables. Originally committed as revision 22620 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
