Some flac muxers write truncated metadata picture size if the picture
data do not fit in 24 bits. Detect this by truncting the size found inside
the picture block and if it matches the block size use it and read rest
of picture data.
This workaround is only for flac files and not ogg files with fl
Hi David,
Not a full review, but a minor point that popped in mind.
It is common to pad serially numbered files with 0. E.g. if you have <1000
files, the 9th file will be named file009.txt.
Is this case handled by the expansion? Or is it assumed that the text file
numbers are not zero-padded?
