Multiple video AdaptionSets with dash

Description

I am trying to create a dash manifest which includes multiple video AdaptationSets (specifically DASH, not webm_dash). However, it seems all output streams of AVMEDIA_TYPE_VIDEO are automatically grouped within a single AdaptationSet, and categorized as additional Representations within the dash manifest.

While webm_dash_manifest supports the adaptationSets parameter, reviewing dashenc.c, it does not seem there is currently a way to include multiple video AdaptationSets in a dash manifest.

Since Representations are intended to only differ in quality level (resolution / bitrate), and AdaptationSets are intended for different content, this is a limitation because there is no way to include multiple videos of different content (such as different camera angles) in a dash stream.

How to reproduce:

% ffmpeg -i in1.mov -i in2.mov -map 0:v -map 0:a -map 1:v -f dash dashtest/Manifest.mpd
