Anton Khirnov	0ed1eeb744	lavf/dv: use a more granular timebase for audio One that is fine enough to represent all DV audio sample rates. Audio packet durations are now sample-accurate. This largely undoes commit `76fbb0052d`. To avoid breaking the issue fixed by that commit, resync audio timestamps against video if they get more than one frame apart. The sample from issue #8762 still works correctly after this commit. Slightly changes the results of the lavf-dv seektest, due to the audio timebase being more granular.	2 years ago
Anton Khirnov	c7a852b638	lavf/dv: do not set video timebase more than once Current code will call avpriv_set_pts_info() for each video frame, possibly setting a different timebase if the stream framerate changes. This violates API conventions, as the timebase is supposed to stay constant after stream creation. Change the demuxer to set a single timebase that is fine enough to handle all supported DV framerates. The seek tests change slightly because the new timebase is more granular.	2 years ago
Anton Khirnov	f7b3fc4afe	lavc/dv: rename constants to follow our naming conventions CamelCase for enum tags, ALL_CAPS for enum values.	2 years ago
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	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.

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

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
