Подробное описание

An API-specific header for AV_HWDEVICE_TYPE_VIDEOTOOLBOX.

This API currently does not support frame allocation, as the raw VideoToolbox API does allocation, and FFmpeg itself never has the need to allocate frames.

If the API user sets a custom pool, AVHWFramesContext.pool must return AVBufferRefs whose data pointer is a CVImageBufferRef or CVPixelBufferRef.

Currently AVHWDeviceContext.hwctx and AVHWFramesContext.hwctx are always NULL.
