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	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	27f22f3383	all: Remove unnecessary libavcodec/internal.h inclusions 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
Andreas Rheinhardt	fbb9e0dbc8	avcodec/dv: Don't pretend VLC allocation can't fail It can and therefore we switch from a heap allocated VLC table to a VLC initialized via the mechanism for static VLCs, but without an actual static VLC. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 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
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

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

Carl Eugen Hoyos	6b87f0707d	Do not try to encode DVCPRO HD, it produces broken files.	13 years ago
Mans Rullgard	c75eca9d37	dvenc: do not call dsputil functions with stride not a multiple of 16 Allowing dsputil functions to assume the stride is a multiple of 16 even for smaller block sizes can simplify their implementation. This appears to be the only place this guarantee is not met. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	70d54392f5	lowres2 support. The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
