GStreamer OpenGL ES Rendering #1

Closed rsavignon closed 4 years ago

rsavignon commented 4 years ago

Hi all, i don't know if this is the most appropriate repository, but i am facing a problem regarding showing video frames in a OpenGL ES window on the new dunfell branch. This was working on zeus branch, but i had to upgrade due qt version requirement.

Raspberry pi 3 Model b

gst-launch-1.0 videotestsrc ! glimagesink

When i execute the above test command i get a error message like this:

Setting pipeline to PAUSED ... 0:00:00.283948213 10169 0x1ffdb40 WARN glimagesink gstglimagesink.c:1010:_ensure_gl_setup:<sink> error: glGetString not defined or returned invalid value ERROR: Pipeline doesn't want to pause. Got context from element 'sink': gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayEGL\)\ gldisplayegl0"; ERROR: from element /GstPipeline:pipeline0/GstGLImageSinkBin:glimagesinkbin0/GstGLImageSink:sink: glGetString not defined or returned invalid value Additional debug info: ../gst-plugins-base-1.16.2/ext/gl/gstglimagesink.c(1010): _ensure_gl_setup (): /GstPipeline:pipeline0/GstGLImageSinkBin:glimagesinkbin0/GstGLImageSink:sink Setting pipeline to NULL ... Freeing pipeline ...

I certified myself that libbrcmGLESv2.so had the glGetString with the command : nm -gDC /usr/lib/libbrcmGLESv2.so

0000e080 T glGetShaderPrecisionFormat 0000d234 T glGetShaderSource 0000d0a0 T glGetShaderiv 00008810 T glGetString 000089bc T glGetTexEnvfv 0000890c T glGetTexEnviv

And set GL_VERSION environment variable to some value.

export GL_VERSION='2.1'

Thanks in advance.

Hi Rafael,

This is not the correct place to report a bug like this.

I am not a gstreamer user.

Best regards, Scott

Sorry Scott, i'm using jumpnow yocto meta layers to build rpi3 images. On the zeus branch the command was executed successful and a window popped up, but with dunfell branch it doesn't. By the way, congratulations for excellent work on yocto meta layers.
