* avcodec/put_bits: Make skip_put_bits() less dangerousAndreas Rheinhardt2020-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before c63c303a1f2b58677d480505ec93a90f77dd25b5 (the commit which introduced a typedef for the type of the buffer of a PutBitContext) skip_put_bits() was as follows: static inline void skip_put_bits(PutBitContext *s, int n) { s->bit_left -= n; s->buf_ptr -= 4 * (s->bit_left >> 5); s->bit_left &= 31; } If s->bit_left was negative after the first subtraction, then the next line will divide this by 32 with rounding towards -inf and multiply by four; the result will be negative, of course. The aforementioned commit changed this to: static inline void skip_put_bits(PutBitContext *s, int n) { s->bit_left -= n; s->buf_ptr -= sizeof(BitBuf) * ((unsigned)s->bit_left / BUF_BITS); s->bit_left &= (BUF_BITS - 1); } Casting s->bit_left to unsigned meant that the rounding is still towards -inf; yet the right side is now always positive (it transformed the arithmetic shift into a logical shift), so that s->buf_ptr will always be decremented (by about UINT_MAX / 8 unless n is huge) which leads to segfaults on further usage and is already undefined pointer arithmetic before that. This can be reproduced with the mpeg4 encoder with the AV_CODEC_FLAG2_NO_OUTPUT flag set. Furthermore, the earlier version as well as the new version share another bug: s->bit_left will be in the range of 0..(BUF_BITS - 1) afterwards, although the assumption throughout the other PutBitContext functions is that it is in the range of 1..BUF_BITS. This might lead to a shift by BUF_BITS in little-endian mode. This has been fixed, too. The new version is furthermore able to skip zero bits, too.

* avcodec/libx264: fix chroma quantizer offset usageTakio Yamaoka2020-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default for the chromaoffset field in AVCodecContext is zero, which until now always ended up overriding the AVOption-set value, thus leading to the AVOption not working. Additionally, the previous usage prevented the usage of negative values, while both the variable as well as x264's API would successfully handle such. Thus, the default value of the AVOption is changed to match the default of x264 (and what is currently the default for the AVCodecContext chromaoffset field), and the checks are changed to check for nonzero values. This way: 1. the library default is still utilized if the value is zero. 2. both negative and positive values are correctly passed to x264. For historical context, this was initially similarly implemented in 5764d38173661c29d954711dd5abfddf709e9ba4, and then b340bd8a58c32453172404a8e4240e3317e341da broke the value.

* avcodec/mpegaudiodec_template: Check CRCs for layer1 and layer2Michael Niedermayer2020-08-04
| | | | | | | | | | | This differs from the MPEG specification as the actual real world files do compute their CRC over variable areas and not the fixed ones listed in the specification. This is also the reason for the complexity of this code and the need to perform the CRC check for layer2 in the middle of layer2 decoding.
