NAME

       sreview-transcode - transcode the output of sreview-cut into production-quality media
       files

SYNOPSIS

       sreview-transcode TALKID

DESCRIPTION

       "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

CONFIGURATION

       "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".

SVG TRANSFORMATIONS

       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.
