I am able to use the v4l2videodec plugin with MMAP, now I want to try the dmabuf export from v4l2 and import dmabuf buffers to glimagesink. I upgraded gst to 1.7.91 so that I have the dmabuf support in glimagesink. Mesa version is 11.1.2. I'm using the following pipeline: GST_GL_PLATFORM=egl GST_GL_API=gles2 gst-launch-1.0 $GSTDEBUG $GSTFILESRC ! qtdemux name=m m.video_0 ! h264parse ! v4l2video32dec capture-io-mode=dmabuf ! glimagesink I stalled on this error: eglimagememory gsteglimagememory.c:473:gst_egl_image_memory_from_dmabuf: eglCreateImage failed: EGL_BAD_MATCH which in Mesa is: libEGL debug: EGL user error 0x3009 (EGL_BAD_MATCH) in dri2_create_image_khr_texture Do someone know how the dmabuf import is tested when the support has been added to glimagesink? Or some pointers how to continue with debugging? Thanks for the answers. -- regards, Stan
