Ronald S. Bultje	b4bccf3e4e	wma: fix off-by-one in array bounds check. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	349b7977e4	wma: fix invalid buffer size assumptions causing random overreads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	9d3050d3e9	wma: don't return 0 on invalid packets. Return 0 means "please return the same data again", i.e. it causes an infinite loop. Instead, return an error. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	b5ec638343	cosmetics: indentation and spacing	14 years ago
Justin Ruggles	9d06d7bce3	Remove the add bias hack for the C version of DSPContext.float_to_int16_*().	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
Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Eli Friedman	c7310b7b2b	Silence warning "new qualifiers in middle of multi-level non-const cast are unsafe". Patch by Eli Friedman, eli d friedman a gmail Originally committed as revision 24080 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
Carl Eugen Hoyos	2cbc1ec676	Fix indentation after r22414. Originally committed as revision 22415 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	445a9deea6	Print error messages on errors. Originally committed as revision 20757 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	f78501b264	Fix apparent 10l typos introduced in r8627. These typos moved the exponent pointer too far ahead. Fixes issue1055. Originally committed as revision 20756 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	8b4a6d47b2	WMA: extend exponent range to 95 Hopefully this will be enough. Fixes issue 1565 (again). Originally committed as revision 20598 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	168f92ffaa	WMA: extend exponent table up to 75 Fixes issue 1565. Originally committed as revision 20593 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	0e71841b05	WMA: fix loop unrolling in decode_exp_vlc() The count can be a non-multiple of 4 after all. Originally committed as revision 20081 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	ff00b94e9d	WMA: use type punning and unroll loops in decode_exp_vlc() GCC does stupid things if these assignments are done using floats directly, so fill the runs using integer operations instead. Also unroll the loops since the length is always a multiple of 4. Originally committed as revision 20077 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c0d1463da7	WMA: use a table instead of pow() in decode_exp_vlc Originally committed as revision 20076 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	952e872198	Drop unused args from vector_fmul_add_add, simpify code, and rename The src3 and step arguments to vector_fmul_add_add() are always zero and one, respectively. This removes these arguments from the function, simplifies the code accordingly, and renames the function to better match the new operation. Originally committed as revision 20061 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	0a07e9d012	WMA: remove some unused variables Originally committed as revision 20030 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	6044538b37	WMA: use DSPContext.butterflies_float Originally committed as revision 19981 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Sascha Sommer	9970c61b4b	Introduce WMACoef typedef for decoded coefficients and change default type to float so that the run level decoding functionality can be shared with wmapro Originally committed as revision 19231 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Sascha Sommer	c0e9b2e84f	Move run level decode functionality to ff_wma_run_level_decode so that it can be reused for wmapro Originally committed as revision 19171 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Siarhei Siamashka	7d485f165f	Support for getting (i)MDCT output multiplied by a constant scaling factor. Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	110baa2e99	Remove unused variable from wma_decode_block() found by CSA. Originally committed as revision 18568 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
