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
Michael Niedermayer	00bbc09309	Store range coder state transition table. Use a better table, 2% compression gain for foreman Originally committed as revision 22763 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
Michael Niedermayer	ef768b0c32	Disallow VLC coding with more than 8 bits as there are several bugs in that code that could lead to broken files. AC coding is unaffected. Originally committed as revision 22638 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5d7bc46c2d	Throw out last experimental warning that was printed for colorspaces with more than 8 bits per component. This does no good except scaring users away. Originally committed as revision 22633 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	0e22d68834	Remove the word "experimental" Originally committed as revision 22629 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	15 years ago
Lars Täuber	7c6208d4c0	Use "FFmpeg video codec #1" instead of "FFmpeg codec #1" as codec long name. patch by Lars Täuber, lars.taeuber gmx net Originally committed as revision 19749 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	f83c57735e	indent Originally committed as revision 18679 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	68f8d33bec	Support >8bit per component YUV in FFV1. decoding becomes slower, encoding becomes faster, with gcc on duron. some inlining overrides like av_flatten are added to keep inlining similar to before. Originally committed as revision 18674 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	217d34e307	Force speed irrelevant calls to get/put_symbol() to be noinline. We need to change decode_line to always_inline because gcc decided not to inline it anymore once we force some calls to get/put_symbol() to be non inlined and this decision of gcc would lead to a 10% overall speed loss. 100k smaller object file, no speed change Originally committed as revision 18673 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	3788e661f1	Optimize sign handling in get_symbol(). Originally committed as revision 18672 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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
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
Aurelien Jacobs	199436b952	moves mid_pred() into mathops.h (with arch specific code split by directory) Originally committed as revision 16681 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
