[Bug]: Intel Arc 140V – No hardware HEVC decode (GPU usage = 0%)

### Which component impacted?

Video Processing

### Is it regression? Good in old configuration?

No, this issue exist a long time

### What happened?

I have an issue with hardware video decoding on Intel Arc A140V integrated graphics.
When playing HEVC (H.265) videos, the CPU usage goes very high (close to 100%) while the GPU video decode graph in Task Manager remains at 0%. It seems the hardware decoder is not being used.

### What's the usage scenario when you are seeing the problem?

Playback

### What impacted?

System details:

Intel 268V
GPU: Intel Arc 140V (integrated)

Driver version: 32.0.101.6881

OS: Windows 11 Pro build 26100.5074

Players tested: VLC, Windows Media Player

Same issue in all players (software decode only).

Steps to reproduce:

Play any HEVC (H.265) video (e.g. 1080p or 4K).

Open Task Manager → Performance → GPU → Video Decode.

GPU decode stays at 0%, CPU load becomes very high.

Expected result:
Video should be decoded by the GPU (hardware acceleration).

Actual result:
Only CPU decoding is happening.

Please check if hardware HEVC decode is properly supported on Arc A140V or if this is a driver issue.
