Reimar Döffinger	d780511b94	Reduce log level of "Extracting .. channel downmix" to AV_LOG_DEBUG, the message is pointless to ordinary users and is printed once per frame. Originally committed as revision 21486 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	0b882b4009	Fix crash in MLP decoder due to integer overflow. Probably only DoS, init_get_bits sets buffer to NULL, thus causing a NULL-dereference directly after. Originally committed as revision 21426 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	547fc46ca7	Remove pointless CONFIG_MLP_DECODER preprocessor check. The file is only ever compiled if the MLP decoder is enabled. Originally committed as revision 20968 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ramiro Polla	52ae1e869b	mlp: Indent. Originally committed as revision 20255 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ramiro Polla	7fd8806924	mlp: Only initialize VLC tables once. This caused a crash when multiple instances of the decoder were started at different times. Bug reported by Maxim Anisiutkin. Originally committed as revision 20254 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ramiro Polla	13bd2044d3	mlp: Simplify adressing of state and coeffs arrays for both filters by making the arrays sequential. Originally committed as revision 18841 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	e282272667	mlpdec: Fix possible writing out of array bounds introduced by being under-paranoid in r18651. Originally committed as revision 18763 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	e8d341ce19	mlpdec: Split sync word error and MLP sync word check. The previous code would print the wrong error message for MLP streams with TrueHD noise type. Originally committed as revision 18762 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	aff42ee0ff	mlpdec: Fix indentation that got mangled from copy&paste. Originally committed as revision 18761 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	bf4f19dc65	mlpdec: Move MLP's filter_channel() to dsputils. Originally committed as revision 18721 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	77b12f809b	mlpdec: Simplify filtering code by using only one counter variable. Originally committed as revision 18695 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	420df93037	mlpdec: Don't overallocate buffers. Now that max channels and primitive matrices are properly validated, there is no need to be paranoid that random data will be overwritten. As a bonus this makes matrix_coeff 16-byte aligned between matrices. Originally committed as revision 18651 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	309616b249	mlpdec: Validate num_primitive_matrices. Originally committed as revision 18650 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Ramiro Polla	5d9e4eaa6d	mlpdec: Check for {matrix,filter}_changed as soon as they are incremented. Originally committed as revision 18610 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

Ramiro Polla	0091d8a164	mlpdec: matrix_out_ch must not be greater than max_matrix_channel, and not max_channel. Originally committed as revision 18335 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Ramiro Polla	a44b9f9574	mlpdec: Simplify &foo[0] to foo and use index (which has just been initialized to MAX_BLOCKSIZE) instead of MAX_BLOCKSIZE, so both copies to/from state data look alike. Originally committed as revision 18233 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
