Video site parsing scripts -------------------------- totem-pl-parser can "parse" pages from certain websites into a single video playback URL. This is particularly useful for websites which show a unique video on a web page, and use one-time URLs to prevent direct linking. This feature is implemented in a helper binary, which needs to be installed next to this README file, in totem-pl-parser's `libexec` directory, or in the directory pointed to by the `TOTEM_PL_PARSER_VIDEOSITE_SCRIPT` environment variable. totem-pl-parser used to ship such a script that used libquvi, but doesn't anymore. The first script (when sorted by lexicographic ordering) in the aforementioned directory will be used. The API to implement is straight-forward. For each URL that needs to be checked, the script will be called with the command-line arguments `--check --url` followed by the URL. The script should return the string `TRUE` if the script knows how to handle video pages from this site. This call should not making any network calls, and should be fast. If the video site is handled by the script, then the script can be called with `--url` followed by the URL. The script can return the strings `TOTEM_PL_PARSER_RESULT_ERROR` or `TOTEM_PL_PARSER_RESULT_UNHANDLED` to indicate an error (see the meaning of those values in the [totem-pl-parser API documentation](https://developer.gnome.org/totem-pl-parser/stable/TotemPlParser.html#TotemPlParserResult)), or a list of `<key>=<value>` pairs separated by newlines characters (`\n`) The keys are listed as [metadata fields](https://developer.gnome.org/totem-pl-parser/stable/TotemPlParser.html#TOTEM-PL-PARSER-FIELD-URI:CAPS) in the API documentation, such as: ``` url=https://www.videosite.com/unique-link-to.mp4 title=Unique Link to MP4 author=Well-known creator ``` Integrators should make sure that totem-pl-parser is shipped with at least one video site parser, in a separate package, such as a third-party parser that implements a compatible API as explained above. Do **NOT** ship third-party parsers in the same package as totem or totem-pl-parser itself.
