Tag Scheme

get_iplayer uses the AtomicParsley utility to add metadata tags to output files in MP4 and M4A format. The table below describes the scheme used to convert get_iplayer metadata into tags for downloaded programmes. The tag names were selected to match AtomicParsley parameter names. Each tag is mapped, where possible, to the corresponding get_iplayer substitution parameter, AtomicParsley arg, MP4 atom. The list of iTunes fields indicate where each tag will appear in the iTunes Get Info dialog. Conversion rules specific to particular fields are indicated in the footnotes. If you wish to experiment with variations, the conversion of get_iplayer metadata to tag values is encapsulated in the Tagger::tags_from_metadata subroutine.

The TV* and hdvideo tags are written to video files only. The iTunes podcast-related tags are written when a --tag-podcast option is specified. All other tags are written to all files.

Re-tagging files

Metadata tags can be added (or re-added) to existing files with the --tag-only option. Use --pid to identify the programme whose metadata is to be used and --tag-only-filename to identify the file to modify.

get_iplayer --pid=b08h31x5 --tag-only --tag-only-filename="Weather_for_the_Week_Ahead_-_2017-03-13_b08h31x5_original.mp4"

Notes

Obsolete AtomicParsley

Some Linux/BSD distros ship obsolete versions of AtomicParsley. Tagging will likely fail on large files (>4GB) if you are using AtomicParsley < 0.9.4, and there may be other problems. You may be able to install an alternate version of AtomicParsley - see manual installation. See the AtomicParsley Bitbucket repository for instructions on building your own up-to-date version. If you use Windows or macOS and follow the installation instructions, you will have an up-to-date build of AtomicParsley.

Content Encoding

The get_iplayer metadata is assumed to be encoded as UTF-8 and is then re-encoded as necessary for the different tagging applications. This doesn't always hold true, so substitution characters may sometimes appear in the tags, particularly lyrics or longDescription.
