Constant Not Responding

I don't know what the deal is with Gameshow, but every time I've tried to use it, it goes from when I select my capture cared and webcam to "Not responding"...every time.  Why would I pay for the full version ($70), when the basic free version doesn't even work?  It'd be nice if they could actually make a working version having less bells & whistles than the paid version, but that's just a logic minded person's opinion.

     That would be a USB bus bandwidth issue.

    You cannot use two high bandwidth devices on the same USB bus, or you will see this issue. We even include a tool in the Window menu that allows you to isolate which devices are on which bus numbers, so you can swap them around for the best bandwidth spread.

     The paid version is $29, not $70. And it does work as long as you correctly spread out your high bandwidth USB video devices. If you plug two devices that need 50MBps throughput, for a total requirement of 100MBps, to a USB bus that can only provide 60MBps, well that has nothing to do with Gameshow.

     The free version does work, and it's only limitation is video quality.

  • Well, firstly, they're not on the same USB port ("USB bus" is redundant as  USB means Universal Serial Bus).  Secondly this would that imply using Gameshow is not plausible for 95% of laptops.  It also tends to start several "processes" though none will close then.  Give me a moment to get my specs from my device.

  • TL;DR - Please provide a screenshot of the USB Bus window tool. If they show as different buses, we can explore the video format tables for that device.

    If you want to be particular, then sure, USB Bus is redundant. Not everyone knows what USB stands for, or how they work though, and for a discussion like this, it is important to distinguish the difference between the port and the bus. I will try to be specific.

    I have never once owned, or seen, a laptop that mapped all of its USB ports to a single bus. That would be an incredibly poor design oversight. Unless of course it only has one or two USB ports... but those are usually mapped to a different bus than the internal webcam so it does not trigger the issue, unless you plug a webcam and capture card into that single USB bus, then yes, you will have problems. Not an appropriate device for the workflow at that point.

    Regardless, a Universal Serial Bus has a finite amount of bandwidth, regardless of how many ports are routed to that bus. 

    This is not a new or unique concept, it applies to anything and everything USB.

    • Each Universal Serial Bus can have one, or MANY more ports routed to it.
    • Regardless of how many ports are on that bus, you still have the same finite amount of bandwidth for that bus.
    • USB2.0 is rated for 480Mbps, or 60MBps.
    • USB3.0 goes up from there.

    At this point, its just a simple calculation. If I have 4 ports, split evenly over 2 USB2.0 buses, I know I have two 60MBps buses at my disposal. 

    If I am wanting to use two USB video devices, each requiring 35MBps, then plugging them both into a 60MBps bus means I will be short by 10MBps of bandwidth. You will drop video frames and trigger the warning. So, the correct action, would be to make sure each video device is on its own bus, leaving 25MBps left on each bus for lower bandwidth stuff like mice/keyboards/audio devices/ etc.

    Desktop motherboards usually have one bus per USB port tower on the back. They also usually provide multiple USB headers for front panel ports. Each header being it's own bus. The number of ports on that bus will vary depending on the case headers you plug into it. Maybe it is a 3.5inch tray that combines a card reader and two usb ports on that bus. It can vary.

     

    In order to mitigate the guessing game of which ports are tied to which bus, we have a tool that will identify what devices are on what bus. If you see that your two high bandwidth video devices are on the same bus number, then one of them should be swapped to another port until you can confirm they show on different bus numbers.

    ------------

    NOW, once it is confirmed that they are on different buses, with no other competing devices on that bus, we can look into it being a video format issue for the particular device you are using.

    There are a number of formats that can be used to acquire video from a USB device. They vary in quality and bandwidth usage. It is possible the device does not play well with one format or another, and we would need to make an exception for that particular device. This is very rare however.

    On this topic, there was a similar occurrence with the Windows 10 anniversary update was released. Windows removed MJPEG and as such, susceptible devices were then connecting with higher bandwidth methods. Windows 10 shortly released a fix that added MJPEG back.
