Andreas Cadhalpun	564dd3f0f4	mpeg4videodec: silence ubsan warning s->ac_val[0][0] is of type 'int16_t [16]', but points into a larger buffer. Here it is used as base pointer to find the correct position in the larger buffer by adding 's->block_index[n] * 16' and thus as 'int16_t *'. This fixes clang's ubsan runtime error: index out of bounds for type 'int16_t [16]' Fixes: test_case.mp4 Found-by: Tyson Smith <twsmith@mozilla.com> Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	9 years ago

Anton Khirnov	2c6811397b	lavc: add profiles to AVCodecDescriptor The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.	9 years ago
Clément Bœsch	fb99ef0bd3	avcodec: use AV_OPT_TYPE_BOOL in a bunch of places	9 years ago

Ganesh Ajjanagadde	2cbaa078d1	avcodec: use HAVE_THREADS header guards to silence -Wunused-function When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions.

Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	10 years ago
