Hi,

When enabling the "Use Hardware acceleration if possible" for video, I just get a black output - no output.

MM V 4.0.6
Windows 10 64
Intel core i7
Geforce 940MX with 461.72 driver (latest)
Intel Onboard (nvidia set to use Geforce card with Mad Mapper)

Any ideas appreciated. Thanks.

Hi,
If you go to Preferences / Engine, you will see if MadMapper is running on nVidia or Intel GPU. Can you tell me which GPU it's using ?
Anyway it doesn't mean that hardware decoding will be done on nVidia GPU.
You should first update your Intel & nVidia drivers and see if the problem gets solved. Most issues on windows are solved with GPU drivers update...
Another point: using hardware decoding is great on very small CPUs (I used it to get full HD playback on Intel Nuc / Intel ComputeStick or Azus Vivostick because CPU doesn't handle a single Full HD h264 movie). But on a decent CPU, it's better to keep CPU decoding. I can decode about 8 4k movies on my desktop before getting frame drops. If you need more than your PU can give, use HAP or HapQ codec: https://hap.video/ We have native support of this codec, it's really optimized: frames are zipped with a fast decoding library and store in a format that your graphics card can directly receive (so doing part of the decoding)
Cheers
