Transcoding MythTV for UPnP transport to a PS3

Posted by Travis Collins at August 3, 2008 10:22 PM

MythTV has a builtin UPnP server that can serve recorded shows to the PS3's UPnP client. However, the format that MythTV records may not be directly compatible with the PS3s video client.

I use the following user job in MythTV to transcode recorded videos to a format that is compatible for the PS3 over UPNP. My PCHDTV-5500 card captures audio in MPEG-PS and the PS3 will only play MPEG-TS formats (thus the requirement to transcode the video file).

Be sure to change the two instances of "/storage/mythtv" to your appropriate mythtv video directory.

mythcommflag -c %CHANID% -s %STARTTIME% --gencutlist; mythtranscode -c %CHANID% -s %STARTTIME% -p autodetect -m -e dvd --honorcutlist; mv /storage/mythtv/%FILE%.tmp /storage/mythtv/%FILE%; mythcommflag -c %CHANID% -s %STARTTIME% --rebuild --clearcutlist;

This is script performs the following steps:

converts the already created commercial list into a "cut list"

Requires that commercial flagging run before this user job

transcodes the captured video to a tmp file.

this step also cuts commercials

overwrites the original capture file with the new file

rebuilds the commercial flags so that a normal myth frontend doesn't skip the commercials that have been cut in the transcoding

Enter the script above as a "User Job" and enable that user job on any recordings (under advanced options in MythWeb) you'd like to be able to view on your PS3.

You specify -e dvd. I have some HD MPEG2 TS files that I converted w/ your command, and which then would not play properly w/ VLC. However, specifying -e ps lets me play them in VLC. I have not tried -e ps w/ a PS3 (as I don't have one). Try it out, if you would.

When you use the -e ps option, the PS3 fails to play audio.
