Comment 2 for bug 1636135

Have you tried playing any of these videos in mediaplayer-app? How about the inline dash video player in the video scope? Any different results there?

You are correct in that we can only play one video at a time at the moment due to how things are wired up with hardware video acceleration. I'm not sure if more than one is possible with hardware acceleration. Would need to investigate this further. This might be a good case for software decoding, but we currently don't have that path working at the moment via GStreamer. It only ever tries to use hardware video codecs for all video playback.
