As well as exif metadata for JPEG images Ogg metadata should be supported, however implementing this won't be as easy as exif for numerous reasons: * There's no standard libary for it, we could use File_Ogg (see http://pear.php.net/package/File_Ogg) but it's in beta state currently, alternetively we could parse the raw output from ogginfo(1) * We can't use img_type to determine that it's an Ogg file which should be parsed, we could fall back to anything with an .ogg extension
I tried mucking around with the Ogg::Vorbis::Header::PurePerl Perl module and it works very well, time to make Vorbis.php that parses the output of a custom perlscript.
Created attachment 507 [details] An Ogg tag reader using Ogg::Vorbis::Header::PurePerl; This is an Ogg Vorbis tag reader using Ogg::Vorbis::Header::PurePerl, I think the best way to support Ogg metadata currently is to use something like this, the php implementations seem to be really immature. We could just use STDIN and STDOUT to communicate with the program: $ ./ogginf jly.ogg Comments: title = Just Like You Imagined artist = Nine Inch Nails album = The Fragile - Left Disc tracknumber = 7 encodedby = Ari genre = Industrial date = 1999 Info: bitrate_upper = 0 framing_flag = 1 channels = 2 version = 0 blocksize_0 = 4096 blocksize_1 = 512 rate = 44100 length = 229 bitrate_nominal = 224963 bitrate_window = -1 bitrate_lower = 0 offset = 304
I think this is pretty much being done in the OggHandler extension...
OggHandler extension stores OGG metadata.
