I think that's quite an edge case. You have both avconv and ffmpeg installed but you want to choose ffmpeg. Wouldn't uninstalling avconv be an option?

[dt1973]

I never installed it myself so it must be some sorta dependency.

[dt1973]

You're right, this is an edge case. That Runnable test case uses Ubuntu, and as with everything else in Ubuntu, installing ffmpeg is way harder than it has to be. And, somehow, it mysteriously manages to install avconv as well:

https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

Naturally, this is not a problem on OpenBSD where I actually host my app so I'm just going to close this one.

Thank you for your support.

@owahab how does paperclip-av-transcoder look for avconv? I removed /usr/bin/avconv as well as /usr/share/avconv but it still insists on using avconv:

[attenzione]

i don't know why (strange decision), but av gem tests for avprobe instead of avconv, so you need to remove avprobe and you can leave avconv as is in the system

[dt1973]

Indeed you're right. Thank you @attenzione!

[dt1973]

@owahab maybe you could make it look for avconv instead of avprobe?
