This is a refinement of 654bfb04 Avoid nullptr arithmetic in VP8BitReaderSetBuffer and removes an unneeded/redundant check in 2 of the 3 calls to this function: * VP8InitBitReader: `start` is guaranteed to be non-NULL * CopyParts0Data: `start` is allocated and checked In `DoRemap()` `last_start` will be NULL before the partitions are parsed. This is the only call that was missing a check. The offsetting of a NULL pointer in `VP8BitReaderSetBuffer` was harmless in this case as the bitreader will not be used meaningfully until there is enough data to begin decoding partition 0. In that case the bitreader will be initialized by `ParsePartitions()` and updated by `DoRemap()` when more data is available. Bug: 393104377 Change-Id: Ib44bc35e00e5129c592d742a2469420cd3d0e858

WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools 'cwebp' and 'dwebp' to compress and decompress images respectively.
See https://developers.google.com/speed/webp for details on the image format.
