- New library needed for mpegparse?
It now needs libz because I added a CRC32 check to the picture frames.
Doing 'make mpegparse' will work correctly.
Hi Geoff,
I just tried to use mpegfix with my DVB-t recordings in Germany
(Debian32, b2c2_flexcop_pci, Kernel 2.6.14)
It crashes here after
Yet another update.
Robin Gilks ran into an interesting problem of streams being
corrupted, which turned up to be another bug in replex when updating
GOP timestamps (basically there is a corner case where a GOP will be
falsely detected in the middle of an imageit has a probablility of

Yes. This is needed to find the PTS discrepencies. I tried to find a

After lots of help from Cory and Paul, here is a new version of mpeg2parse:

It now supports discontiuous PTS, though if an audio frame gets
dropped and the video frame is present, the result may be an A/V
desync. I haven't seen this happen yet though.

These aren't really a problem, though I'd certainly use -f on the

difference). All the above says is that the expected PTS doesn't
match what was actualy found (actual on the left, expected on the
right). A new frame is inserted

This doesn't make sense. Did you pipe the result to a log file or
less? There is no way it could stop printing at the middle of a line
(that I can think of), so the real ending point is

Even so, I'd certainly be interested to see this stream.
I messaged you off the list with an address where to download it. If
no I meant that you need to just let it run (dumpingto the screen).
you still have the same buffering going on. It is 23 minutes into the
program though, so it did get through quite a bit of it.
Ah yes... I'm being an idiot. Here's the *unbuffered* output up
to where it stops:

If you have the capability, sending me the tail of the original mpg

Geoffrey,
This sounds good, I will have a go this weekend (may have to be sunday)
with some uk dvb streams and let you know how i got on. I will also try
and get you an example stream with two audio tracks and subtitles for

Okay, here we go:

Follow the directions in README to build it.
The code has basically the same features as the last version I posted,

That's not needed, you can simply use the command line option on
mythtranscode mpeg2 to mpeg2.

Just as a status update, the new transcode work I'm doing is
progressing quite well.
I have incorporated replex into the code (mplex was giving me
fits),and switched to libmpeg2 for frame processing...This basically
involved yet another rewrite of the code.
I have spent a lot of time validating

Hello,
I am using the current svn of mythtv with dvb-t in the UK. When I
record shows I get a .mpg recording. I would like to transcode the
files from the .mpg to another .mpg file (basically using a cutlist not
too worried about space). I have tried using the mp4 compression and
this throws out
