Andreas Rheinhardt	30a5b66a7c	avcodec/g729dec: Mark decoders as init-threadsafe Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

Michael Niedermayer	336f9461df	avcodec/g729dec: Avoid using buf_size buf_size is not updated as buf is advanced so it is wrong after the first iteration Fixes: Timeout (160sec -> 27sec) Fixes: 18658/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_G729_fuzzer-5729784269373440 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Michael Niedermayer	576746b4e3	avcodec/g729dec: Factor block_size out This will be used in the next commit Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Michael Niedermayer	f64be9da4c	avcodec/g729dec: require buf_size to be non 0 The 0 case was added with the support for multiple packets. It appears unintended and causes extra complexity and out of array accesses (though within padding) No testcase Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Michael Niedermayer	d468da8d79	avcodec/g729dec: Check for KELVIN && 6k4 This combination would assume different block sizes throughout the code so its better to error out. Fixes: signed integer overflow: -1082385168 * 2 cannot be represented in type 'int' Fixes: 19110/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_ACELP_KELVIN_fuzzer-5643993950191616 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Michael Niedermayer	bf9c4a1275	avcodec/g729dec: Use 64bit and clip in scalar product The G729 reference decoder clips after each individual operation and keeps track if overflow occurred (in the fixed point implementation), this here is simpler and faster but not 1:1 the same what the reference does. Non fuzzed samples which trigger any such overflow are welcome, so the need and impact of different clipping solutions can be evaluated. Fixes: signed integer overflow: 1271483721 + 1073676289 cannot be represented in type 'int' Fixes: 18617/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_ACELP_KELVIN_fuzzer-5137705679978496 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
