+Currently, only VA-API is supported for encoding the digital intermediate, although Nageru might
support NVIDIA's NVENC at some point in the future. In particular, this means that Intel Quick
Sync Video (QSV), the hardware H.264 encoder present on all modern Intel
GPUs, is supported. QSV is more than fast enough to keep up with 720p60 in
further editing or transcoding without strong generational loss.) Thus, the
QSV stream is not intended for streaming to end users of the Internet; it will
need to be reencoded by some external means, or you can use Nageru's x264

By default, Nageru uses zerocopy from the GPU to the VA-API buffers in order to
reduce memory transfer bandwidth, but this depends on EGL support (as opposed to
the older GLX standard), and also that the GPU you are rendering to also
supports VA-API. NVIDIA's proprietary drivers do not support either. Unfortunately,

about it (Qt has already initialized using EGL), so on NVIDIA
systems, Nageru will exit with an error message asking you to set *--va-display*
