Hi there,
I’m getting a sporadic crash on the 20.02 release when using the camera pipeline with Wayland/EGL.
This is when using MESA 19.1.6 - and when using a gstreamer GL filter plugin in the pipeline.
I can reproduce this crash with the following pipeline, and the crash occurs within minutes.
gst-launch-1.0 -v v4l2src device=/dev/v4l/by-path/platform-1b0ac00.camss-video-index3 ! video/x-raw,width=1280,height=720,format=NV12 ! queue ! glupload ! glcolorconvert ! glcolorscale ! ‘video/x-raw(memory:GLMemory),width=400,height=400,format=RGBA’ ! gltransformation scale-x=2.0 ! gleffects_blur ! gltransformation ! glimagesink
When reverting to MESA 18.1.9, this problem goes away.
backtrace here and attached:
Got context from element ‘sink’: gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"(GstGLDisplayWayland)\ gldisplaywayland0";
