MythArchive stream selection failure

When using ProjectX to demux DVB-T recording, mythburn.py fails with following log.

Can you also add from mythburn.log the bits between renameProjectXFiles start ----------------- renameProjectXFiles end ------------------

So I can see which streams the script is finding.

Here is the log:

OK thanks. I can see what's going wrong but don't know why yet. I'm going to need some more of the output from projectx to figure this out. I'm interested in the parts around where it says something like

---> new File: 

or anything like

--> stream omitted

My guess is the private stream is being ignored and so no file is being created for that which is throwing the stream parsing off.

I've attached full mythburn.log and progress.log, hope these help.

[paulh]

(In [15510]) Pass the list of stream ids to projectx that we want. Speeds up the demux/cutting because projectx doesn't waste time fixing streams we are going to dump anyway.

Refs #4475.

[otto at kolsi dot fi]

The original stream selection problem is now fixed.

[paulh]

(In [15609]) Add option to add subtitles to DVD's created by MythArchive?.

There's a new 'Add Subtitles' setting that when turned on will cause the script to automaticaly add subtitles to the DVD for any files that have them.

Only DVB subtitles are currently supported and requires that you tell MythArchive? to use ProjectX as the cutter/demuxer.

It's only been very lightly tested with a few DVB-t recordings I had to hand so there are probably still issues to be fixed.

This commit also should fix #4475.

[J.Pilk@…]

I just installed ProjectX. On the first attempt to use it in Mytharchive (mythburn.py (0.1.20080325-1-fixes) from ATrpms), and using a cutlist, I got failure in ffmpeg while converting from mp2 to ac3.

In fact the stream files in the work folder are misidentified: stream.mv2 is the audio and stream0.mp2 is the video.
