Hardware-accelerated encoding, compression, frame rate, data rate #174

Open 3rd3 opened 2 years ago

3rd3 commented 2 years ago

I am wondering what kind of framerate I can expect with what kind of hardware at Full HD resolution (e.g. Lenovo Tiny vs Raspberry Pi) and with what kind of data rate.

Does Deskreen compress the video at all?

Is hardware-accelerated H.264 encoding planned/feasible?

VNC, RDP, Guacamole and NoVNC do not do compression, it seems:

On Fedora 40 Linux / Wayland / Gnome, when I run Chrome with google-chrome-stable --ignore-gpu-blocklist --enable-features=VaapiVideoDecoder,VaapiVideoEncoder,VaapiVideoDecodeLinuxGL,VaapiIgnoreDriverChecks,WebRTCPipeWireCapturer, when I share my screen, I see the GPU being used with intel_gpu_top. However, I haven't been able to reproduce this GPU usage with Deskreen.

I have tried using these arguments with Deskreen and additional ones: --enable-gpu-rasterization --enable-zero-copy --disable-software-rasterizer --enable-accelerated-2d-canvas --enable-native-gpu-memory-buffers --use-gl=desktop --enable-accelerated-video --enable-accelerated-video-decode

Any thoughts would be appreciated!
