[mythtv-users] RTJPEG, MPEG4 and analog TV

[Kevin Bailey]

When I first tried making analog recordings (HD3000 on 0.20),
they wouldn't play correctly. As far as I could tell, they were
playing double-time. You could tell what was going on, but it
was painful.

I tried looking directly at one of the recorded files under
/var/mythtv but neither "file", nor any video player could
figure out what type of file it was.

Under Settings//Recording Profiles/V4L based/Default, I noticed
that the format was set to RTJPEG. I had never heard of this
format and so gave the alternative, MPEG4, a try. It worked.

The trouble is, this doesn't help for live TV. It captures a
second or so of data, plays it quickly, and then pauses for a
half-second.

Since MPEG4 is probably harder on the CPU to play (I have an AMD
3400+), and even harder to generate, and so I can play live TV,
I'd like to get this RTJPEG (if that's what the live TV process
is generating) working.

As I understand things, RTJPEG was the first supported format by
myth so I'm a little surprised that a more modern CPU can't
handle it.

I have the audio rate set to 48kHz everywhere I could find
and I have "sync to video" set under Settings/Playback.

Anyone with this kind of set-up had this problem and gotten
it to work ?
