Re: [mythtv-users] Anyone tried MPEG2 to MPEG2 transcoding?

2005-07-07 Thread Phill Edwards
 Hmmm, unless there's special code to handle MPEG2-MPEG2 transcoding,
 I'd guess that you'd end up with a Myth NuppelVideo container format
 file, with MPEG2 video and either raw or MP3 audio.  Probably *not*
 what you're looking for.

Actually, this sounds like what I AM looking for! I want a Myth file
with MPEG2  MP3 - I just want it to use up less space than the
default recording size that I get off DVB-T capture.

FYI, after issuing the mysql update I set up a MPEG2 -- MPEG2
transcode rule but they are all failing with an error according to the
job status screen. I will need to take a look at the log files to see
what the problem is.

Phill

resending message .. as got relay error from the mailing list.
sorry if it shows up as double message.


I used vlc to transcode MPEG2-TS (HD stream, 1920x1080, 5.1 DD AC3) to
MPEG2 (720x480, 2.0 stereo) when I was using media mvp.


thanks

Is it possible to do this as a user job ? you can use your own command line 
and set whatever options you want.

Does the Recording Profiles screen not provide a sufficient GUI for
this SQL statement? It should be somewhere under Setup - TV,
depending on your menu theme. Many other options are also available,
in addition to choice of video codec ...

No. I think you only get that if you're compiling from CVS and you
enable something somewhere in the code. I'm using ATRPMs and the only
formats you get to transcode to are MPEG4 or RTJPEG - that's why I
needed to enable MPEG2 via mysql.
