create_window

int AVMediaCodecDeviceContext::create_window

Disabled by default.

It can be enabled by setting this flag directly, or by setting AVDictionary of av_hwdevice_ctx_create(), with "create_window" as key. The second method is useful for ffmpeg cmdline, e.g., we can enable it via: -init_hw_device mediacodec=mediacodec,create_window=1
