I’ve installed XiboScreenTwo_v4R405.msi and got it working. But after some time, I noticed one oddity. I have multiple videos scheduled to this player, and the scheduling is exactly the same for screens one and two.
ScreenOne one works perfectly. ScreenTwo freezes the first two to three seconds of every single video in the scheduling. I’ve connected to this station using Anydesk, and even through Anydesk the freezing is noticeable, and always only on ScreenTwo. SreenOne does not freeze.
I’ve checked the task manager and there are no CPU nor memory spikes. The computer does not have a lot of RAM, but it’s not bootlenecked either (8GB RAM, plus 8GB swap). Disk is also not bootlenecked (a 240GB M2 drive).
Any ideas of what could be causing this?
My setup:
Xibo 4.0.5
Windows 11 with two HDMI screens
8GB RAM+8GB swap
240GB M2 drive
i5-12500T CPU
Thank you,
Roberto

Please describe in detail the issue you are experiencing, including any errors shown on the Player Status page or in the Logs section of the CMS.
Sorry to hear about the play back issue on your Xibo for Windows (XfW) player where in the video freezes in your second player. Please make sure that you have followed all the steps to install and setup the Multi Install - Windows Player in this guide.
Coud you please try to optimize the video you are using for your scheduled layouts using a 3rd party tool called HandBrake? To do so, you can download and follow the steps in this guide.
Unfortunately, it didn’t help. I reencoded two videos that where being shown in the second player, but the freeze in the start of the videos remains. Also, I’ve checked the installation guide, but no step seems to be missing in relation to what I did.
I have replicated the issue on my end and have reported this to our development team for further investigation. Thank you for reporting the issue and in the meantime, thank you for your patience while we are working on the fix for the issue. You may check Xibo Blog to view next releases to get updated when the issue is fixed.
Our developers have tested and investigated this issue for you and has advised that the freezing on the second player for 7 seconds is highly caused by the underlying hardware specification. We recommend that you test it on a PC with a more powerful specification in terms of RAM and CPU as not all hardware can decode two videos at the same time efficiently.
We’ve made video decoding as efficient as possible within the current architecture of the player application. We use a WPF control (MediaElement) for rendering video which generally works well for a single video.
Running Xibo on a second screen doesn’t involve anything more complicated than running a second instance of the application. That’s twice the work, no optimisation. Running an extended desktop across both screens inside a single application might be slightly more efficient, but I suspect not by much.
The most likely bottleneck in the hardware is the graphics card, as the player app will be trying to use hardware video decoding. Your graphics card may not be capable of doing two full screen videos at once. You could try reducing the resolution of both monitors.
Jerry is right, but I hope the additional context is useful.
As suggested, I’ve tried reducing the resolution, but that didn’t help. Probably the GPU. The computer we are using has a good CPU (i5-12500T), but with an onboard GPU. Not much I can do about it at the moment. Since it’s a hardware limitation, there isn’t much to be done.
