[FFmpeg-devel] [PATCH 05/15] libavformat/flacdec: Export samples md5 as metadata

[Tomas Härdin]

Could maybe use some kind of compile-time assert that
FLAC_STREAMINFO_SIZE == MD5_BYTE_SIZE + 18. I'm thinking putting in st-
>codecpar->extradata + st->codecpar->extradata_size - MD5_BYTE_SIZE for
the offset

----------------
Make it possible to verify sample checksum for FLAC files

Possible other solutions:
    • Make ffmpeg FLAC demuxer capable of optionally check sample
checksum. One tricky thing is that we currently have heuristics to not
trust the checksums based on other metadata (known broken transcoding
software)
