I just installed the Jon Severinsson ffmpeg PPA, and I cant watch any video and get audio only, I get a need extra plugins needed install? and then packaged dependencies could no be resolved . Here are the screenshots, any help?
Jon Severinson's ffmpeg is NOT Ubuntu's ffmpeg!
Last year, some of the ffmpeg developers split off and started their own version ("fork") of ffmpeg, called libav. For various reasons, Ubuntu ended up choosing libav as the version to include in Ubuntu 12.04. See this question for more info.
Both ffmpeg and libav are actively developed, in parallel, right now. Jon's PPA contains the latest original ffmpeg packages, not the libav ones (which are in the official Ubuntu repository)
Both sets of packages have different, incompatible and confusing versioning schemes -- and this is a problem because they also share some of the same components, dependencies, etc. due to their shared heritage. libav 0.8.x is as "new" as ffmpeg 0.10.x!
Right now, Ubuntu applications are set to depend on the libav versions of software.
But when you install Jon's ffmpeg, Software Center/apt gets confused because the audio/video player needs dependencies, but different versions of those are already installed!
Bottom line: if you install Jon's ffmpeg, you have to be prepared to separately install or build from source your preferred audio/video players. ffmpeg and libav cannot co-exist on an Ubuntu installation at this time (unless you install one of them manually).
So, unless you need some particular feature only implemented by ffmpeg, stick to libav since it's the officially supported fork and is as new and actively developed as ffmpeg.
