Projectx problems

[QuadraQ]

Hi all,

I'm trying to use Projectx to demux my mpeg2 file and I'm getting horrible amounts of errors and useless final m2v and ac3 files (way too small).

Here's the log (shortened a bit)

Any ideas? This is the first time I've run ProjectX so don't really know where to look.

Try the version of Projectx from here:
http://oozoon.de/main_en.html

On the right hand side is the link to the version you are using, and a modified version last of which was updated on 21 Feb 2009. Try the updated version and see if that helps.

You could also try PVAintrumento which is separate Demux tool. It can be found here:
http://www.offeryn.de/dv.htm

Download the latest version at the top right hand side, currently version V2.1.0.21
I have seen a similar effect to what you have listed, and I suspect its something to do with AC3 audio. Hopefully one of the two above options will be of help to you.

I'm afraid that this version of ProjectX didn't do it either. At lease not with the default options. The error messages were a little different, but the output was the same: file that are much too small with large portions of the video and audio simply gone.

Everyone seems to rave about how wonderful ProjectX is and it does indeed look like it's a nice program, but it doesn't seem to like my 1080i NTSC AC-3 source MPEG2 at all. (Originally created through Media Center, and the MPEG2 stream pulled from the dvr-ms file using DVRMSToolbox which calls ffmpeg to do the work.) Is there a good guide to ProjectX somewhere that would explain all (most) of the options? Thanks.

OK I'm giving this a try. Did a scan of the mpg file and it keeps saying this over and over:

Maximum GOP size exceeded at 00:12:53.011.

Could that be the source of my problem - the video has extra large GOPs?
