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
Christophe Gisquet	eacf2e8eb3	dv: better split weight tables assignment This is a mostly cosmetical patch in preparation for the following. 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

Diego Biurrun	d4b63054d9	cosmetics: Drop unnecessary parentheses around return values.	13 years ago
Mans Rullgard	a1e98f198e	get_bits: remove A32 variant The A32 bitstream reader variant is only used on ARMv5 and for Prores due to the larger bit cache this decoder requires. In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only statistically significant difference between ALT and A32 is a 4% advantage for ALT in FLAC decoding. There is thus no (longer) any reason to keep the A32 reader from this point of view. This patch adds an option to the ALT reader increasing the bit cache to 32 bits as required by the Prores decoder. Benchmarking shows no significant change in speed on Intel i7. Again, the A32 reader fails to justify its existence. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	b6ae086682	dv: simplify bitstream splicing in dv_decode_ac() This is simpler and fixes some overflow checker warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	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>	13 years ago
