EGL Surface Creation on Wayland Weston

[spear_kor]

Dear All,

I am having the following error: 

"EGL: Warning: No default display support on wayland" and gst error message "Debug deails: ../../../../git/gst-libs/gst/gl/gstglbasefilter.c(490): gst_gl_base_filter_find_gl_context (): /GstPipeline:rtsp_gst_pipeline/GstGLUploadElement:glupload
Error: Failed to initialize egl: EGL_BAD_DISPLAY"

I am initializing:

  this->eglDisplay = eglGetCurrentDisplay ();

  this->eglSurface = eglGetCurrentSurface (0);

  this->eglContext = eglGetCurrentContext ();

  eglMakeCurrent(this->eglDisplay, this->eglSurface, this->eglSurface, this->eglContext);

and then;

  GstGLContext *context;

  GstGLDisplayEGL *display;

  display = gst_gl_display_egl_new();

  context = gst_gl_context_new_wrapped(GST_GL_DISPLAY(display), (guintptr) this->eglContext , GST_GL_PLATFORM_EGL, GST_GL_API_GLES2);

  gst_object_unref (display);

Any suggestions how to solve EGL error?

Dear Bio_TICFSL,

Compositor is Weston using Wayland protocol. Actually there was a different error, when I apply the commands you mentioned above, I started to get the error I mentioned. Seems like the problem is with my code.

I will also check the pdf.

Thanks

Hello spear_kor,

Which compositor you use? check that for the display it created & export like below.

export WAYLAND_DISPLAY=wayland-0 // Compositor created display

export XDG_RUNTIME_DIR=/tmp // can be some temporary dir

Try to use the

export DISPLAY:=0.0

Try to use "i.MX_Linux_User's_Guide.pdf" from Linux doc package for some details.
