The above says:
You have two options for multimedia player in Tizen application.
■Use HTML5 tag. It doesn’t support DRMs and streaming engines like DASH, HAS, HLS and SmoothStreaming.
■Use avplay API or Samsung TV product API. It supports DRMs and streaming engines like DASH, HAS, HLS and SmoothStreaming.
Is this true? They say it's a private SDK, is that why I can't see any references to it online? And do we need the private sdk to stream HLS at all, or is it only for fancy player stuff?
HTML5 video tag does not supports HLS on Tizen platform.
You need to use AVPlay API to play streaming or DRM content.
Try to test AVPlay (Video Play) Sample in your emulator.
