Comment (by Mattias Wadman):
{{{-err_detect +crccheck}}} does not seem to make any difference in output
or logging.
Yes I understand ffmpeg primary tries to workaround and fix issues but in
this case I don't think the file is broken, at least {{{flac -t
flac_junk_frame_issue2.flac}}} does not find any errors.
Add optional samples md5 verification would both detect broken files and
implementation bugs. As a note ffmpeg:s flac encoder/muxer has support for
calculating and writing samples md5.
