PROB: A limited amount of cameras can be shown on Intel Graphics Accelerator hardware
The information applies to:
- LuxRiot 1.1.18 and more recent
Symptoms
LuxRiot is only capable of showing limited about of cameras (exact number may vary depending on several factors, including video resolution and pixel format), the rest of the cameras may show an error message, especially “… Is there a required codec properly installed? …“.
Description
The problem is caused by probable incompatibility between Intel Graphics Accelerator hardware driver and DirectX 9 subsystem. DirectX 9 Video Mixing Renderer 9 is a default method of presenting video in LuxRiot starting LuxRiot 1.1.18 and a limited number of its instances start successfully with undescriptive failure reasons for the rest of instances that fail to start.
Intel Graphics Accelerator is an integrated video subsystem on a number of Intel motherboards, including Intel D915 GEV series.
Solution
To resolve the problem, configure LuxRiot to use Video Mixing Renderer 7 (shipped with DirectX 7 and more recent versions). Choose Tools item in main menu, Options menu item and set DirectX options as shown below:
Intel Graphics Accelerator running with Video Mixing Renderer 7 do not cause the problem. You may need to restart LuxRiot DVR Client for the changes to have effect.
