[mythtv-users] Updated: pdatranscode

[Jeff volckaert]

Here's an updated pdatranscode script.  It uses xvid instead of mpeg4.
 The old one had a slight audio sync problem.

Here's a copy of my installation instructions:
> I created a simple script to transcode recordings for a PDA (Dell Axim
> X51V in my case).  The files get stored in the directory pda under my
> video directory.  I just copy the files I want onto a memory card and
> watch them using TCPMP.  An hour long show comes out to 105M or so
> (that's alot of shows on a $40 2G card).  They play wonderfully on the
> PDA.
>
> I created a second user job to run after Zach's removecommercial
> script from the Wiki.  I check only those shows I want a copy of for
> the PDA.
>
> Here's the commands I used to create the user job:
>
> mysql> use mythconverg;
> mysql> UPDATE settings SET data='/usr/local/bin/pdatranscode %DIR%
> %FILE% "%TITLE%" %STARTTIME%' WHERE value='UserJob2';
> UPDATE settings SET data='PDA Transcode' WHERE value='UserJobDesc2';
> mysql> UPDATE settings SET data='1' WHERE value='JobAllowUserJob2';
>
> Then I create a script call "pdatranscode" and put it in
> "/usr/local/bin".  I have two methods to transcode here.  The first
> one uses mythtranscode's low quality transcoder (number 29 on my
> system).  I have low quality set to 320x240 with a 300k bitrate.  An
> hour long show came out to 136M.  The second method uses mencoder.
> Mencoder produced a show 105M in size.  Uncomment whichever you prefer
> to use.
