SUMMARY


STEPS TO REPRODUCE
1. Run krdp on host AMD A10-7800 Kaveri (Radeon R7 GPU with working vaapi) 
2. Connect from krdc on client

OBSERVED RESULT
```
[h264_vaapi @ 0x7f821c37e700] Driver does not support some wanted packed
headers (wanted 0xd, found 0x1).
```
And blue screen on krdc from client, mouse cursor seems to move correctly
though.

EXPECTED RESULT
Should see the screen.

## SOFTWARE/OS VERSIONS

### Host
Operating System: Fedora Linux 40
KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2
Kernel Version: 6.9.12-200.fc40.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 4 × AMD A10-7800 Radeon R7, 12 Compute Cores 4C+8G
Memory: 6.7 GiB of RAM
Graphics Processor: AMD Radeon R7 Graphics

Note: I am using the 6.9.x kernel because vappi is broken on my GPU on the 6.10
kernels, its already logged on MESA.

Host VAAPI

```


### Client
Operating System: Fedora Linux 40
KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2
Kernel Version: 6.10.11-200.fc40.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i7-4710HQ CPU @ 2.50GHz
Memory: 15.4 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 4600

Note: running the client with an Nvidia GTX 850M doesn't change the result, so
it's a host side issue.
Also attempted with both krdc and remmina.
