At the moment and especially in this case, VBR or Non-compliant MP3s
seem to complete successfully as far as Rivendell is concerned.
You either write in lots of extra checking (complicated) or you
transcode everything with external tools.
Maybe it would be possible to use mp3val and parse the output, if its
bad run it through ffmpeg to wav and then import; if its not bad just
import as normal? But then do you want to transcode twice without user
input or for the audio purists do you put the burden on them to provide
better files?
I think it would be less work to rely on external tools either way.

Um, so if there's a way to "fix" VBR or "improper" MP3 files before
importing them with rdimport, how come rdimport can't do that work for
us? Has anyone looked at the transcoding method inside
utils/rdimport/rdimport.cpp? Is it worth taking the time to improve
rdimport?

I've run into stuff like that too, usually it is an issue with the MP3
not necessarily meeting the standard format for mp3's, but being "close
enough" to play on most players. It can also be the vbr stuff as
suggested.
You could try running the mp3's through mp3val before importing and see
if it finds issues. To test, just try running mp3val on some copies of
the original files and see if it finds problems.
Otherwise - as suggested - it might be easiest to uncompress the files
before importing.
I built a Rivendell machine for WZBR AM 1410 a couple years ago when
that
station moved from Brockton to Boston, MA; it's been running flawlessly.
Last month, however, my client decided to lease the station 24/7 to a
third party, and had me move the machine to the transmitter site
where its
function would be to run a top-of-hour ID on top of programming that
would
be coming from the broker's new studio via Internet stream.
The broker's new studio isn't ready, so he's been feeding the station
from
somewhere in California. The stream has been dropping out a lot, so I
suggested he give me his audio files and I'd load them into the
Rivendell
machine and play them from the transmitter site until his studio is
ready.
His audio files are all MP3's, alas, but I rdimported them all last
night
and put them on the air about three hours ago.
At the end of each cut, I hear an electronic buzz for five to ten
seconds
just before the transition to the next cut. I don't know what's going
on,
but I'm guessing it has something to do with the transitions. I've tried
fiddling with the crossfade times and using "play" instead of "segue"
transitions, but nothing seems to answer.
Just now, I heard a clean transition, but it happened about four minutes
into a supposedly 17 minute cut. Looking at Edit Markers, the cut is in
fact only four minutes long; somehow Rivendell got bad information from
rdimport.
I believe a good many of these cuts are shorter than Rivendell thinks
they
are. Is there a way to fix this other than manually through Edit Markers?
