EGL is our main vehicle for interoperability with multimedia, camera and graphics APIs.
We provide function to export VPIEvent objects to be consumed by other APIs, as well as function to import images and sync objects from them.
#include <vpi/EGL.h>
Export a recorded VPI event to EGL sync object.
The resulting object can be used to allow a command queue belonging to an external API to wait on a recorded VPI event.
The exported EGLSync must be destroyed using eglDestroySyncKHR before the VPI event object is destroyed.
| event | [in] event that is being exported |
| eglDpy | [in] EGL display for which the sync object is being created. |
| eglSync | [out] Exported EGL sync handle |
#include <vpi/EGL.h>
Create an event object by wrapping around an EGL sync object created from another client API.
The created event can be used by vpiEventSync / vpiStreamWaitFor to synchronize VPI tasks with a command queue from an external API.
| eglSync | [in] EGL sync handle |
| event | [out] pointer to an event handle |
#include <vpi/EGL.h>
Create an image object by wrapping around an EGLImage.
The underlying image object does not own/claim the memory block.
| eglImage | [in] EGL image created from another client API |
| flags | [in] flags |
| img | [out] pointer to an image handle |
