Some time ago ffmpeg split into two forks under the name of ffmpeg and libav.

Debian is following the libav fork in it's distribution and in an upcoming upload the binary /usr/bin/ffmpeg will be replaced by /usr/bin/avconf.

As far as I know it is not necessary to switch immediately, but Winff should be upgraded to allow for either binary (from the Debian perspective, with a preference for avconf). I know you can set the location of the binary in the preferences, but I think that with the location set, Winff should be able to find the proper binary.

I think in the future also Windows and other distributions might be hit by this issue.

As a reference see Debian bug 654984: http://bugs.debian.org/654984

Hmm, not /usr/bin/avconf but avconv.

I have implemented the checks for the correct binary in my local checkout, but reading up [1], I see that there are some inconsistencies between avconv and ffmpeg. That issue is larger, because the preset file will need adjustment and especially the way we create the command line will have to change. The options that operate on the input file need to go BEFORE the input file "-i". I think we need a good brainstorm on how we are going to implement this in Winff.

Matt/Ian, do you want me to commit, or not now, as we need the other fixes as well.

Will follow up via mail.

So far, I don't think we have input file operations, so I this issue should be closed, as the checks for avconv are in place.
