Video resize appears to be broken after 7.1 udpate

We have a small video view in our onboarding flow that is clickable to expand full screen. It was working perfect during dev with 7.0, but after the upgrade to 7.1, the video boundaries stay at 360x203, but the actual video looks like its playing full screen behind it. Essentially I only see a small portion of the entire 1080p HLS video playing. Additionally often when in the small window its highly distorted with green lines throughout. Anyone else have a smaller-than-fullscreen video acting up and have some ideas?

		<Video
		id="fifteenSecondIntro"
		width="360"
		height="203"
		translation="[875,50]" />

    Not sure about Scene Graph, but we had a similar issue. Firmware 7.1 makes video display resolution logic consistent across devices. Beforehand, it was actually inconsistent and matched the resolution of your _application_. So if you were in HD (720p) mode the coordinates and resolution of the video also corresponded to this. After the change, the coordinates and resolution match that of the _display_. So you'll need to translate the video coords, etc to display coords, etc.

    Sample code:


    app_display_size = GetDisplaySize()
    roku_display_size = CreateObject("roDeviceInfo").GetDisplaySize()
    x_factor = roku_display_size.w/app_display_size.w
    y_factor = roku_display_size.h/app_display_size.h
                                   
    dst_x = dimensions.X*x_factor
    dst_y = dimensions.Y*y_factor
    dst_w = dimensions.Width*x_factor
    dst_h = dimensions.Height*y_factor
     
    print "SetDest1 (" ; dimensions.X ; "," ; dimensions.Y ; "," ; dimensions.Width ; "," ; dimensions.Height ; ")"
    print "SetDest2 (" ; dst_x ; "," ; dst_y ; "," ; dst_w ; "," ; dst_h ; ")"
     
    m.VideoPlayer.SetDestinationRect(dst_x,dst_y,dst_w,dst_h)

    Looks like I only have access to the 'width' and 'height' of the video component in scene graph:

    width	float	0.0	Sets the width of the video play window in pixels. If set to 0.0 (the default), the video play window is set to the width of the entire display screen.
    height	float	0.0	Sets the height of the video play window in pixels. If set to 0.0 (the default), the video play window is set to the height of the entire display screen.


    Maybe theres a hidden api value for controlling the size of the video vs the 'play window' referenced above? At this point, recreating outside of scene graph isn't an option. I'd just replace it with an image, but this is a poor experience for our Roku users.

    From what I'm seeing, there is no way to make a video smaller than full screen using scene graph. This would break or prevent anyone from creating a PIP, which is what I was working on next 😞 😞

    Not true. You can create PIP with Scene Graph. You place the video tag in a custom component and then set the resolution on that. Our app has PIP (necessary actually) and we've been toying with Scene Graph for a while. If you put the video tag in a custom component, you can animate its size, opacity, etc.

    retrotom, are you using firmware 7.1? I have it set up this way and can manipulate the width and height, but that is only the window. The video itself is playing full screen.

    Yes, this is on 7.0 and 7.1. What device are you on? It'd take me a while to do a full inventory, but I can check 10+ roku hardware versions.

    It looks like this may be behavior due to a missing ui_resolutions from the manifest. I added:

    ui_resolutions=sd,hd,fhd


    and looks to be working now. I missed this somehow in the docs as required for scene graph applications, and that is certainly strange behavior when this is missing.
