GstGLMemory

GstGLMemory is a #GstGLBaseMemory subclass providing support for the mapping of OpenGL textures.

#GstGLMemory is created or wrapped through gstgl.glbase_memory.GLBaseMemory.alloc with #GstGLVideoAllocationParams.

Data is uploaded or downloaded from the GPU as is necessary.

The #GstCaps that is used for #GstGLMemory based buffers should contain the GST_CAPS_FEATURE_MEMORY_GL_MEMORY as a #GstCapsFeatures and should contain a 'texture-target' field with one of the #GstGLTextureTarget values as a string, i.e. some combination of 'texture-target=(string){2D, rectangle, external-oes}'.

struct GstGLMemory {

GstGLBaseMemory mem;

uint texId;

GstVideoInfo info;
