{{{
;FFMETADATA1
key=value\\
key2=value
}}}
The backslash here is used to escape itself, not the following newline
character. Yet the ffmetadata demuxer will read a key with value
'value\\\nkey2=value'.
This behavior can also be observed by creating an ffmeta file with ffmpeg
and probing it with ffprobe.
{{{
# Double backslash for terminal escaping
$ ffmpeg -metadata key=value\\ any.ffmeta
...
Output #0, ffmetadata, to 'any.ffmeta':
Metadata:
key : value\
encoder : Lavf58.45.100
$ ffprobe any.ffmeta
...
Input #0, ffmetadata, from 's.ffmeta':
Metadata:
key : value\
: encoder=Lavf58.45.100
# The encoder metadata property is gone.
...
}}}
