Hi,

it seems that you are ingesting two (or more) tracks with the same flavor (e. 
g. presenter/presentation) and more than one of these tracks contain audio 
and/or video streams. Matterhorn needs *one* audio stream and *one* video 
stream per flavor only, and it doesn't know which one to choose.

Make sure to ingest tracks in a way where there are no two tracks with the same 
flavor and both of them containing audio and/or video.
