Ok, thanks :)

The fix is in CVS, I'll be making the 1.1 release in the next couple of days.

Actually.. did the program abort straight after the failed ffmpeg? If so I can re-launch ffmpeg on failure with the new switch settings.

Gah! :D

Most people seem to be using SVN versions of ffmpeg so I think a good way to detect this would be by information obtained from a failure.

I don't suppose you have the log of the failure? If not I can generate one, it's no problem.

Don't you love open source? ;-)

Thanks for the report.

dvdspanky passes on the argument to --arate to the ffmpeg -ab flag. With older versions of ffmpeg the unit of the -ab flag was kbit/s. With newer versions, the unit is bit/s. Unfortunately if I invoke dvdspanky with "-arate 192k", it strips of the "k", thus invoking ffmpeg with "-ab 192", which is an invalid bit rate.

It might be possible to automatically check the version of ffmpeg in order to pass the flag correctly. Unfortunately ffmpeg doesn't have a version number. But it might be possible to first invoke "ffmpeg -h" and do a "grep" on the output:

the old version reports:

-ab bitrate set audio bitrate (in kbit/s)

while the new version reports:

-ab <int> E..A. set bitrate (in bits/s)

For the moment I'll try to modify dvdspanky.c locally to allow me to pass 192kbit/s as "-arate 192k" to dvdspanky (and thus as "-ab 192k" to ffmpeg).
