What is this?

It's a parser for ffmpeg's ffmetadata format, which compresses multiline tags to HTML-formatted single lines for further manipulation.

How do I build it?

You need:

Clone this repository.

Then simply run tup init, then tup, and the executable FFMeta should be produced.

How do I use it?

You need ffmpeg, obviously.

Extract the FFMetadata from some media file with:

ffmpeg -i FILENAME -f ffmetadata tags.txt

Alternatively, use this ffmetadata file and save it as tags.txt:

;FFMETADATA1

Then, use the built binary to extract tags:

cat tags.txt | ./FFMeta --tag TITLE

Note that extracting tags currently has case sensitivity, so --tag TITLE is not the same as --tag title. Multiple tags can be specified simultaneously.

If a tag contains newlines, these will be replaced with <br /> tags, which should look correct when viewed as HTML. To modify how newlines are represented, see line 61 of src/parser.yy.
