Andreas Rheinhardt	a1a8815220	libavcodec: Reduce the size of some arrays This commit uses smaller types for some static const arrays to reduce their size in case the entries can be represented in the smaller type. The biggest savings came from inv_map_table in vp9.c.

Ganesh Ajjanagadde	7b11eead1b	avcodec/ac3: always use hardcoded tables The table in question is a 253 byte one. In fact, it turns out that dynamic generation of the table results in an increased binary size. Code compiled with GCC 5.2.0, x86-64 (size in bytes), before and after patch: old: 62321064 libavcodec/libavcodec.so.57 new: 62320536 libavcodec/libavcodec.so.57 Thus, it always make sense to statically allocate this. Tested with FATE with/without --enable-hardcoded-tables. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Ganesh Ajjanagadde	979572365f	avcodec/ac3enc: fix undefined negative left shift This should fix the undefined behavior reported in: https://trac.ffmpeg.org/ticket/4727. I can reproduce this at runtime: simply stick in an abort call in asym_quant to check if c < 0 and run FATE. I don't know ac3 so I can't confirm if negative coefficients are intentional, but at the moment they clearly are according to FATE. This resolves the undefined behavior. Tested with FATE.

Ganesh Ajjanagadde	7179add427	avcodec/ac3enc: use long long after switch to 64 bit bitrate Commit `7404f3bdb` switched bitrate to 64 bits. This triggers -Wabsolute-value on clang, e.g http://fate.ffmpeg.org/log.cgi?time=20150917122742&log=compile&slot=x86_64-darwin-clang-3.7-O3. Therefore, usage of abs is changed to llabs, which is available on all of the platforms. Unfortunately, LLONG_MAX is not always available, so INT64_MAX is used instead.

Anton Khirnov	2df0c32ea1	lavc: use a separate field for exporting audio encoder padding Currently, the amount of padding inserted at the beginning by some audio encoders, is exported through AVCodecContext.delay. However - the term 'delay' is heavily overloaded and can have multiple different meanings even in the case of audio encoding. - this field has entirely different meanings, depending on whether the codec context is used for encoding or decoding (and has yet another different meaning for video), preventing generic handling of the codec context. Therefore, add a new field -- AVCodecContext.initial_padding. It could conceivably be used for decoding as well at a later point.	10 years ago

Justin Ruggles	08a747afb9	eac3enc: use frame exponent strategy when applicable. This checks if the set of selected exponent strategies for all blocks in a channel are in the frame exponent strategy table, and if so, writes the table index instead of each strategy. This saves up to 7 bits per channel per frame, so the overall effect on quality is small.	14 years ago
Justin Ruggles	b5849f7709	ac3enc: merge AC3MDCTContext with AC3EncodeContext. Since both the fixed-point and floating-point encoders use the FFTContext, this no longer needs to be in a separate context. Also, when a short-transform context is added, the same MDCT window will be used.	14 years ago
