Hi I am unable to flip/rotate my videos in Pot Player. I get
Unable to perform the requested operation!
The possibilities that may cause this issue are:
- Native DXVA may be in use.
- Built-in Video Transform Filter may not be in use.
Preferences -> Filter Control -> Video Transform Filter Usage is set to 'Always Use (Recommended)'

These transforms work if I set DXVA2 Copy-Back to D3D9 or D3D11 but then video playback slows to 10 FPS. How do I fix this?

Try settings Preferences -> Video -> Video Renderer -> EVR Custom Present.
Still unable to transform
Flip Vertical works if set manually in Preferences -> Video -> Effects -> Flip Vertical and the video player is restarted
Setting Flip Horizontal manually the same way does nothing
I'm out of ideas. Flip Vertical and Flip Horizontal both work on my computer.
It's not just flipping. Everything under Video -> Video Effects produces that error message
Try changing the decoders from ffmpeb64.dll to Built-In Decoder. But with DXVA2 Copy-back set to "Do Not Use" you may be out of luck.
No luck no matter which decoder I use. DXVA Copy-back was working before, I don't know why it's running at half FPS for me now
Was looking to play a video in horizontal mirror and came into the same issue here.
For anyone coming across this thread with the same issue. I found a solution/work-around. In Preferences go to Filter Control in the side tab and into the Video Decoder settings. At the bottom of this section click on Built-in Video Codex/DXVA Settings (DirectX Video Acceleration, I didnt know what the acronym stood for) and look for DXVA2 Copy-Back. It is probably set to "Do not Use", I set this to D3D11: Auto. I can't claim to know exactly what this does besides enabling this renderless mode. But this allows the different Video Effects to work, including Flip Horizontal. I tried it with several videos of different type and resolution and haven't seen degradation in the playback by changing this setting.
