<div dir="ltr">I would like to use a X11 window. Problem is I cannot get EGL invoked when using GST_GL_PLATFORM=egl GST_GL_WINDOW=x11. I am verifying this by checking if "EGLImage" is provided as allocater->mem_type in the proposed BufferPool by glimagesink. The sink tries to see if "EGL_KHR_image_base" feature is present in the context created and if it is present, then only proposes EGLImage as a mem_type available. I am able to do this with wayland but not with X11. > > > Hello, > > > > I am trying to use a GstBufferPool proposed by glimagesink in a custom > > decoder plugin with EGLImage as memory type. > > Could you please suggest the windowing system that is to be used when > > creating a EGLContext? > > I could not get x11 window to initialize with EGL. > > If I set environment variables as: GST_GL_PLATFORM="egl" > > and GST_GL_WINDOW="x11" > > glimagesink tries to create a x11 display and window and skips EGL > > completely. > > > > With GST_GL_PLATFORM="egl" and GST_GL_WINDOW="" window creation fails > > and gstglwindow.c says "creating dummy window". > > (plugins-bad/gst-libs/gst/gl/gstglwindow.c#143) > > > > Is there a way to get around this? > > I am using gstreamer-bad-plugins 1.3.2 with Ubuntu 14.04. > > What kind of window do you want to create? > > If you choose > > GST_GL_PLATFORM=egl GST_GL_WINDOW=egl > you will get an offscreen EGL surface as window, and if you want it to > be rendered into something else you'll have to provide a window to the > sink. > > If you choose > > GST_GL_PLATFORM=egl GST_GL_WINDOW=x11 > you will get a X11 window and all the windowing is done via X11, which > also means that an X11 display is used.
