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	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago

Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Carl Eugen Hoyos	0fd0ef7947	Add new decoder property max_lowres and do not init decoder if requested value is higher. Originally committed as revision 24098 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	5b9c11ff96	Fix indentation. Originally committed as revision 22721 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	c787cb339e	Add support for hard-coding the 256kB large dv_vlc_map table. Originally committed as revision 22622 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

Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9514a0841a	Align mb_bit_buffer and vs_bit_buffer as their alignment is checked by assert(). Originally committed as revision 21164 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Tomas Härdin	6d01a97c86	Fail earlier for unsupported resolutions or pixel formats when encoding dv. Patch by Tomas Härdin, tomas D hardin A codemill D se Originally committed as revision 20803 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	c47ca25e74	Make get_bits_left() available for use in libavcodec (was previously held private in dv.c for some reason). See "[PATCH] get_bits_left()" thread. Originally committed as revision 20490 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
Reimar Döffinger	8f1e203a56	Use context instead of NULL for logging. Originally committed as revision 20085 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	ebb651d5f2	Make sure that dv encoder initializes all encoded packet data. The specification does not say which value to use for unused parts, so fill all unused bytes with 0xff, which is consistent with what DV usually uses for reserved or unused parts. Originally committed as revision 20084 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	2ba8301769	Mark all pix_fmts and supported_framerates compound literals as const. Makes no difference for gcc but at least icc can put them in .rodata then. Originally committed as revision 19789 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	20e7c8ae0a	Remove some unnecessary alignment specifiers None of these arrays are used in ways requiring extra alignment. Originally committed as revision 19715 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

David Conrad	580a7465fb	Add a chroma_sample_location field to define positioning of chroma samples Originally committed as revision 18795 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	b275500706	Split bitstream.h, put the bitstream writer stuff in the new file put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
