Michael Niedermayer	5675a11f92	Add a seperate VLC table for progressive jpeg so we dont have to subtract 16 in the inner loop. Originally committed as revision 25545 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 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
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 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	ad9feac9fb	Avoid huge array for rgb ljpeg on the stack. Code tested with an ljpeg i had laying around. Originally committed as revision 20433 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	643fc8f107	Flip (M)JPEG frames encoded by Intel JPEG library. Fixes issues 1464 and 1468. Originally committed as revision 20312 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	643fd8a198	Add a got_picture flag to MJpegDecodeContext which indicates if its picture element is valid. Skip the code handling SOS and EOI if not, since it can not work without a valid AVPicture. This fixes a crash with mjpeg/smclockmjpeg.avi.1.0 from issue 1240 where the decoder returned an invalid AVPicture. Originally committed as revision 19342 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
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

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alexander Strange	8e5f465f4c	Increase alignment for DCT block arrays from 8 to 16 Patch by Alexander Strange ( astrange ithinksw com ) Originally committed as revision 12767 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
