I tried the --debug option. Didn't see anything that was a problem.
Could mythtranscode be at fault? Perhaps it's an timing issue? In
the script, mythtranscode is forked off (and nuvexport does say it's
waiting for mythtranscode to set up the files. It states this twice
before continuing) and then ffmpeg starts and ends abruptly.
Anyone know what I can do?
Search the mailing list for the error and find about a billion
explanations of the issue.

but for good measure and repetition... you're likely missing
yuvdenoise, or are using a too-new unstable release of mjpegtools, in
which yuvdenoise is broken.
nope, it wasn't broken nor missing. But, I did upgrade to the newer
mjpegtools. Now it's broken (!)
I wasn't aware (obviously) that this was such a problem. I have no
problems with nuvexport on the backend, so I thought it was a remote
issue.
I'll keep searching. BTW: with the new mjpegtools, nuvexport bypasses
yuvdenoise because it's broken. Now, nuvexport says that "ffmpeg died
early"
Starting nuvexport in --debug to start ffmpeg individually i find that I
get the error:
"could not find codec parameters"*

There seems to be a couple of solutions to this problem in the archives.
But, the latest one started ffmpeg up successfully for me. Martin
posted this for xvid:
edit /usr/local/share/nuvexport/export/ffmpeg.pm
find the line "-f $videotype"
and add "-pix_fmt yuv420p"
the new ffmpeg requires this new switch.
beware though. if you have this problem, i have also had my mythtranscode
demon break and haven't gotten it fixed yet.
I don't know what this will do to a DVD export (his was an Xvid solution)
So far, it's transcoding. I'll let you know if it works or not.
