Question / Help Screen recording of Adobe AIR app on Windows desktop

[Simon Kendrew]

I have developed an Adobe AIR application for windows 7 desktop that runs at 60fps, full HD. The application does not use DirectX. I would like to record this app being used for promotional purposes, and have tried Camtasia and Action! Recorder (with software encoders), but neither of these achieve the required frame rate.

My PC configuration is:

• i7-3930K @ 3.20GHz
• 32GB RAM
• Windows 7 Pro 64-bit
• 2 x NVidia GT 440 graphics cards
• 500GB SSD

If I upgrade my Nvidia graphics card to one of the newer models, such as a Geforce GTX 970, I can make use of the NVENC technology that provides hardware video encoding of DirectX or the Windows desktop. OBS apparently supports the NVENC technology on the Nvidia cards, to provide improved video recording.

Does anyone have any experience of using OBS + NVENC to record Adobe AIR desktop applications (or non-DirectX), and can I expect to record a decent frame rate?

I think you are confusing capture method with encoding methods. OBS's accelerated capture method uses DX10 to speed up the capture using GPU mem from my understanding. NVENC is just a hardware encoder on the GPU, the alternative is

I'm assuming you've tried window capture with/without compatibility mode enabled? Do you have aero enabled? Aero needs to be enabled for proper game/window capture in windows 7

Thank you for the advice dping. I've now successfully recorded my Windows desktop app at the required frame rate and resolution. Much appreciated!

I used Game Capture mode.
