Description
GstEGLImage represents and holds an EGLImage handle.
A GstEGLImage can be created from a dmabuf with gst_egl_image_from_dmabuf()
or GstGLMemoryEGL provides a GstAllocator to allocate EGLImage's bound to
and OpenGL texture.
Functions
gst_egl_image_from_dmabuf ()
GstEGLImage * gst_egl_image_from_dmabuf (GstGLContext *context,gint dmabuf,GstVideoInfo *in_info,gint plane,gsize offset);
Parameters
context |
a GstGLContext (must be an EGL context) |
|
dmabuf |
the DMA-Buf file descriptor |
|
in_info |
the GstVideoInfo in |
|
plane |
the plane in |
|
offset |
the byte-offset in the data |
gst_egl_image_from_texture ()
GstEGLImage * gst_egl_image_from_texture (GstGLContext *context,GstGLMemory *gl_mem,guintptr *attribs);
Parameters
context |
a GstGLContext (must be an EGL context) |
|
gl_mem |

gst_egl_image_new_wrapped ()
GstEGLImage * gst_egl_image_new_wrapped (GstGLContext *context,EGLImageKHR image,GstGLFormat format,gpointer user_data,GstEGLImageDestroyNotify user_data_destroy);
Parameters
context |
a GstGLContext (must be an EGL context) |
|
image |
the image to wrap |
|
format |

gst_egl_image_ref ()
GstEGLImage *
gst_egl_image_ref (GstEGLImage *image);
Increases the refcount of the given image by one.
gst_egl_image_unref ()
void
gst_egl_image_unref (GstEGLImage *image);
Decreases the refcount of the image. If the refcount reaches 0, the image with the associated metadata and memory will be freed.
