* avcodec/mpegaudiodec: Eliminate many undefined operationsMichael Niedermayer2017-02-20
| | | | | | | | Fixes: 625/clusterfuzz-testcase-4574924406521856 Fixes: 626/clusterfuzz-testcase-4738718621499392 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* libavcodec/mpegaudio: change CONFIG_FLOAT to USE_FLOATMichael Niedermayer2013-12-03
| | | | | | | | The CONFIG_ name-space is set by configure, so its better to use a different prefix here. This also unifies the encoder & decoder define that is used Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Fix ff_mpa_synth_filter_fixed() prototype Rename costablegen.c ---> cos_tablegen.c. Collapse tableprint.c into tableprint.h. Simplify trig table rules Remove potentially unstable filenames from comments in generated files. Ignore generated tables and generated table generator programs.

| * mpegaudio: move some struct definitions from mpegaudio.hMans Rullgard2011-05-19
| | | | | | | | | | | | | | These structs are only used in mpegaudiodec.c, so move them there and remove no longer needed #include lines from mpegaudio.h. Signed-off-by: Mans Rullgard <mans@mansr.com>
| * Move some mpegaudio functions to new mpegaudiodsp subsystemMans Rullgard2011-05-19
| | | | | | | | | | | | | | | | This separation allows these functions to be used in a cleaner fashion from other codecs (e.g. qdm2) and simplifies creating optimised versions of them. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | | | | | | | | | This adds a _fixed suffix to the fixed-point versions of things with both float and fixed-point variants. This makes it more consistent with other dual-implementation things, e.g. fft. Signed-off-by: Mans Rullgard <mans@mansr.com>
