    avformat: add option to parse/store ID3 PRIV tags in metadata. · 8a4cc0a2
    Richard Shaffer authored
    Enables getting access to ID3 PRIV tags from the command-line or metadata API
    when demuxing. The PRIV owner is stored as the metadata key prepended with
    "id3v2_priv.", and the data is stored as the metadata value. As PRIV tags may
    contain arbitrary data, non-printable characters, including NULL bytes, are
    escaped as \xXX.
    
    Similarly, any metadata tags that begin with "id3v2_priv." are inserted as ID3
    PRIV tags into the output (assuming the format supports ID3). \xXX sequences in
    the value are un-escaped to their byte value.
