Michael Niedermayer	2b8b7921c5	avcodec/vp3dsp: Fix multiple signed integer overflow: 46341 * 47523 cannot be represented in type 'int' Fixes: 664/clusterfuzz-testcase-4917047475568640 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Michael Niedermayer	8696f25444	avcodec/rv34: Simplify and factor get_slice_offset() code This also fixes several integer overflows by checking each value before use. Fixes: 662/clusterfuzz-testcase-4898131432964096 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/targets/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago

Carl Eugen Hoyos	560f5188c6	lavc/utils: Make second parameter to apply_param_change() const. Fixes a compilation warning: passing argument 2 of ‘apply_param_change’ discards ‘const’ qualifier from pointer target type	8 years ago
Rostislav Pehlivanov	f19442c069	opus_pvq: remove unneeded assert Since the PVQ search has been well fuzzed and is guaranteed to never break SUM(abs(y[])) == K, the assert is no longer needed. Also the assert only prevented coding the wrong vector index but didn't prevent crashes during searching for it, which made the assert rather informational than practical. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago
Rostislav Pehlivanov	22b8ada7b5	opus_pvq: improve PVQ search for low Ks Since the probelm mentioned only happened when the phase was negative (e.g. the sum had to be decreased), only discarding dimensions with a zero pulse in that case restored the search's previously low distortion at low Ks when the phase is never negative.
