QoS policy istartSession qosPolicy. LATENCY (DRC) drops bitrate fast to protect frame time on bad networks; QUALITY (DFC) holds bitrate and tolerates extra delay; DEFAULT lets the server pick (SDK forces prefer-quality when server returns DEFAULT). Chroma format idownstreamVideoSettings.chromaFormat. YUV 4:4:4 keeps full color resolution — sharper text and desktop/UI edges; 4:2:0 (default) uses less bandwidth and is fine for games. Bit depth idownstreamVideoSettings.bitDepth. 10-bit reduces color banding in gradients (needs an HDR/10-bit-capable display path or the SDK clamps back to 8). 8-bit is the safe default. Keyboard layout istartSession keyboardLayout — the keyboard layout the streamed app assumes. Change it mid-stream with the session's setKeyboardLayout(). Enable microphone upstream iDeclares upstreamMedia MICROPHONE at session start — the SDK requests mic permission and streams audio to the app. Toggle live with the session's captureMic(). Browser will prompt for permission. SDK overrides (key=value…) iExtra configureInternalGdnClientSdkSettings() overrides, URL-encoded: key=value&key2=value2. Examples: bitrate=25 (Mbps), resolution=1280x720, fps=60, h265=1, av1=1, codeclist=H264,H265, hdr=1, sdr10=1, icetransportpolicy=relay, turn=host:3478, bitsperpixel=0.05, touch=1, gamepad=0, unadjustedmovement=1, cursor=none, alwayshidecursor=1, mode=dev, stutter=1, webrtcstats=1. Applied before client creation.
