Showing gstreamer video on QT5 app window

Contributor I

Dear all,

I need a suggestion if you don't mind. Firstly, I want to state that I have no experience in graphics framework of Wayland, X11, etc. I am a fresh learner.

Currently, I am trying to show video using GStreamer and paint it with GLES2. 

My GStreamer pipeline is : 

  rtspsrc location=rtsp:// latency=150
 ! queue ! rtph264depay ! h264parse
 ! v4l2h264dec ! imxvideoconvert_g2d
 ! queue
 ! fakesink

Using handoff signals, I am trying to get the buffer and going to use it on openGL.

However, I cannot get the display and its context on wayland.

I am trying to adapt the idea on qglwtextureshare example of plugins-base-1.0,

Please, check the initializeGL() function. 

- How can we replace "(GstGLDisplay *) gst_gl_display_x11_new_with_display (QX11Info::display())" and "gst_gl_context_new_wrapped (display, (guintptr) glXGetCurrentContext (), GST_GL_PLATFORM_GLX, GST_GL_API_OPENGL);" for Wayland? How can we get display and context?

I would also appreciate any other suggestions.

Dear Bio_TICFSL,

Firstly, thanks for the reply.

I don't actually know what amp is. It is the link for streaming from rtsp server on Axis ip camera.

I have no problem with displaying video via gst-launch-1.0 or cpp implementation of pipeline gst-1.0 api to a sink such as autovideosink, waylandsink or glimagesink. My actual problem is interfering with video buffers, I want to draw things just before or after every decoded frame, on top of the texture which shows video frames.

Hello spear_kor,


What is that file media.amp?, for gstreamer you can add this pipeline

gst-launch-1.0 filesrc location=jellyfish-20-mbps-hd-h264.mkv ! video/x-matroska ! aiurdemux ! \
queue ! h264parse ! v4l2h264dec ! imxvideoconvert_g2d ! queue ! waylandsink

and everything seems to work at 1080p h264.

You can see the video decoder supported with gst-inspect-1.0
