Getting the most out of QtMultimediaKit on mobile

on YouTube ↗47m

" summary

Shows concrete techniques for mobile Qt multimedia: use QtMultimediaKit APIs (QMediaPlayer, QAudioOutput) and pre-load sources to cut startup latency; on Symbian setBufferSize is unsupported so native buffer is 4k (~up to 250 ms) and low latency requires throttling via a custom QIODevice and bytesAvailable (examples reduce to 32 ms / 16 ms). Controls streaming APs via Capability Bearer + setNetworkConfigurations. Demonstrates monitoring 32 MB graphics memory (C7 hit ~25 MB), switching camera to video mode, and real-time GLSL effects using ShaderEffectItem and video-as-texture for Q3D (works better on MeeGo/Harmattan).
