loader

void* AVQSVDeviceContext::loader

The mfxLoader handle used for mfxSession creation.

This field is only available for oneVPL user. For non-oneVPL user, this field must be set to NULL.

Filled by the user before calling av_hwdevice_ctx_init() and should be cast to mfxLoader handle. Deallocating the AVHWDeviceContext will always release this interface.
