[mythtv-users] ANNOUNCE: pdatranscode.pl

[Peter Watkins]

OK, I decided to go ahead and build this for fun.

The main advantages, as I see them, are
 - that it makes it easier to change the output filename
 - it allows you to set a maximum length for each part of the output
   filename
 - that it takes more command line arguments, so the same script could
   be used for more than one user job, e.g. you could encode news shows
   with a "one-per-weekday" scheme like "Nightly_News-Monday.avi" and
   encode episodic shows with a different naming scheme

The full script is here:

Below is the usage output.

Jeff, thanks very much for your work. Playing recordings on my PDA is
something I've wanted to do for quite a while, and your script &
instructions were just what I needed.

Usage: ./pdatranscode.pl --file nameOfRecordingFile [options]
  OR (for compatibility with the 'pdatranscode' shell script from Jeff
Volckaert)
       ./pdatranscode.pl %DIR% %FILE% "%TITLE%" %STARTTIME%
Configuration options:
       --description "description value"
               --dir "dir value" [default: "/video/recordings"]
              --file "file value"
   --filename-format "filename-format value" [default:
"{title:20}-{month}-{day}-{subtitle:20}-{hour}{minute}.avi"]
           --pda-dir "pda-dir value" [default: "/video/recordings/pda"]
             --scale "scale value" [default: "320:240"]
          --subtitle "subtitle value"
             --title "title value"
        --transcoder "transcoder value" [default: "lavc"]

Any configuration variable can be used in the transcoded file by
specifying it in curly braces, for example "{title}-{starttime}.avi"
will produce file names like
"The_Daily_Show_With_Jon_Stewart-20061122215900.avi". Spaces will
be changed to underscore characters, and most characters other than
alphanumeric ASCII will be discarded.

There are a number of special strings that can be used in curly braces:
  year      -- year ("2006") from the start time
  month     -- month ("11") from the start time
  day       -- day ("22") from the start time
  weekday   -- day of week ("Thursday") from the start time
  hour      -- hour ("21") from the start time
  minute    -- minute ("59") from the start time
  second    -- second ("00") from the start time
  basename  -- base recording filename, e.g. "1012_20061122215900"

Also, you can specify a maximum field length by adding a colon and
maximum character count, e.g.
"{title:20}-{month}-{day}-{subtitle:20}-{hour}{minute}.avi"
produces filenames like
"Masterpiece_Theatre-11-19-Prime_Suspect_VII_Th-2100.avi".
