sreview-transcode - transcode the output of sreview-cut into production-quality media files
"sreview-transcode" performs the following actions: · Look up the talk with id TALKID in the database. · Create the preroll slide from the preroll template, after applying template changes to it · If a postroll template is defined, create the postroll slide using the same process as for the preroll slide. If no postroll template is defined, use the statically configured preroll · If an apology template is defined and the current talk has an apology note that is not zero length and not NULL, create the apology slide for this talk · Convert the preroll slide, postroll slide, and (if any) apology slide to a 5-second video with the same properties as the main raw video · For each of the configured profiles, do a two-pass transcode of the concatenated version of preroll, apology (if available), main, and postroll videos to a production video
"sreview-transcode" considers the following configuration values: dbistring The DBI string used to connect to the database pubdir The directory in which to find the output of "sreview-cut" outputdir The top-level directory in which to store production output data output_subdirs Array of fields on which to base subdirectories to be created under "outputdir". The fields can be one or more of: eventid The ID number of the event that this talk was recorded at event The name of the event that this talk was recorded at room The name of the room in which this talk was recorded date The date on which this talk occurred year The year in which this talk occurred workdir The location where any temporary files are stored. Defaults to "/tmp", but can be overridden if necessary. These temporary files are removed when "sreview-transcode" finishes. preroll_template The name of an SVG template to be used for the preroll (i.e., opening credits). Required. postroll_template The name of an SVG template to be used for the postroll (i.e., closing credits). Either this option or "postroll" is required. postroll The name of a PNG file to be used for the postroll (i.e., closing credits). Either this option or "postroll_template" is required. apology_template The name of an SVG template to be used for the apology slide (shown right after the opening credits if an apology was entered). Only required if at least one talk has an apology entered. input_profile A profile that generates videos which can be concatenated with input videos without re-transcoding anything. If not specified, uses the input video as a "profile". output_profiles An array of profile names to be produced (see above for the details). Defaults to "webm".
The transformation performed over the SVG files is a simple "sed"-like replacement of input tags in the template file. All data is XML-escaped first, however. The following tags can be set inside the SVG file: @SPEAKERS@ The names of the speakers, in this format: Firstname Lastname, Firstname Lastname and Firstname Lastname @ROOM@ The name of the room where the talk was held. @TITLE@ The title of the talk. @SUBTITLE@ The subtitle of the talk. @DATE@ The date on which the talk was held. @APOLOGY@ The apology note defined for this talk. If one of these fields has no data for the given talk, then the tag will be replaced by the empty string instead.
