[FFmpeg-devel] [PATCH v2] avcodec/startcode: Avoid unaligned accesses

Up until now, ff_startcode_find_candidate_c() simply casts an uint8_t* to uint64_t*/uint32_t* to read 64/32 bits at a time in case HAVE_FAST_UNALIGNED is true. Yet this ignores the alignment requirement of these types as well as effective type rules of the C standard. This commit therefore

Recently libFLAC gained the ability (first released in FLAC 1.4.0) to create FLAC files containing 32-bit int PCM samples. To keep complexity reasonable, the choice was made to limit residuals to 32-bit integers, which the encoder must make sure of. In case the encoder cannot find any predictor of
