> Hi All,
> regularly, on different forums and mailing lists a requirement popups 
> for a feature to automatically failover switching between main input 
> and a
> secondary input in case of main input unavailability.
> The base motivation: let's say you have a unreliable live stream 
> source and you
> want to transcode its video and audio streams in realtime but you
> want to survive the ocasions when the source is unavailable. So use a
> secondary live source but the transition should occur seamlessly without
> breaking/re-starting the transcoding processs.
> Some days ago there was a discussion on devel-irc about this topic and 
> we concluded that this feature is not feasible inside ffmpeg without 
> "hacking", but a separate client app could do this.
> So I created this example app to handle two separate input sources and 
> switching realtime between them. I am not sure wheter it should be 
> inside the tools subdir.
> The detailed description is available in the header section of the 
> source file.
> I will appretiate your suggestions about it.
> Thank you in advance.
> best,
> Bela Bodecs
