Debugging nuvexport in trunk

I'm trying to export from H264 (the local broadcast HD standard) to Xvid
that I know my underpowered Via Epia will handle.

I got a pretty meaningless error message saying that the output parameters
were incorrect. How do I debug this further?

Well, the error message itself might be useful.

Umm, not sure that will work. nuvexport wants a version of 0.5 and
above, and I'm not sure if this SVN version will qualify. Where is
this from anyways?

If it hadn't scrolled off the top of the xterm I'd have it!! I was looking
for debug options, which I can't find, or some sort of dry run option.

I've just started another session, all defaults, in a few hours when it
gets to the failure point I'll report the actual error.

You have chosen to export 1 episode:

1. Grand Designs:
The Contemporary Cedar Clad Home, Stirling (Sat Mar 20 07:30 PM)
1920x1088 H264 (16:9)
Theo and Elaine decide to settle by building a house sourced from all
over
the world.

* Separate multiple episodes with spaces, or ranges with '-'

c. Continue
n. Choose another show
q. Quit

Choose a function, or episode(s) to remove: c
Where would you like to export the files to? [.]
Enable Myth cutlist? [Yes]
Enable noise reduction (slower, but better results)? [No]
Enable deinterlacing? [Yes]
Crop broadcast overscan border (0-5%) ? [1.5]
Audio bitrate? [128]
Variable bitrate video? [Yes]
Multi-pass (slower, but better quality)? [Yes]
Video bitrate? [768]
Default resolution based on requested dimensions.
Width? [512]
Height? [288]

Now encoding: Grand Designs: The Contemporary Cedar Clad Home, Stirling
Encode started: Mon Mar 22 20:54:48 2010
First pass...
Waiting for mythtranscode to set up the fifos.

Thats the latest stable Gentoo version - media-video/ffmpeg-0.5_p20373 -
to give its full emerge name and version, so I guess that falls into the
0.5 and above category.

Here we go - I said they were pretty meaningless!!

ffmpeg had critical errors:

Error while opening encoder for output stream #0.1 - maybe incorrect
parameters such as bit_rate, rate, width or height

Cleaning up temp files.
Cleaning up child processes.

Ok. Could you please run nuvexport with --debug and let me know the
ffmpeg command line(s)?

Also which version of nuvexport do you run?

Ah - that's what I needed to know. The --help option is not very helpful!

> Also which version of nuvexport do you run?

$ nuvexport --version
Net::UPnP::QueryResponse is not installed!
nuvexport version: 0.5 0.20090726.svn
