OSX Fullscreen capture with avfvideosrc not working

[Matt Barclay]

Hello,

I'm on a OS X 10.11.5 Mac book running Gstreamer 1.9.1.

Using avfvideosrc, I am only able to capture a portion of the screen.  Is it possible to capture the full screen?  Here is the command I'm using:

gst-launch-1.0 avfvideosrc capture-screen-cursor=true capture-screen=true ! video/x-raw,width=1440,height=900,format=UYVY,framerate=30/1 ! videoscale ! videoconvert ! video/x-raw,format=YV12 ! x264enc ! rtph264pay pt=96 ! udpsink host=10.42.0.1 port=5000

The resolution of the Mac is 2880x1800, but setting those in the pipeline doesn't work:

gst-launch-1.0 avfvideosrc capture-screen-cursor=true capture-screen=true ! video/x-raw,width=2880,height=1800,format=UYVY,framerate=30/1 ! videoscale ! videoconvert ! video/x-raw,format=YV12 ! x264enc ! rtph264pay pt=96 ! udpsink host=10.42.0.1 port=5000

Setting pipeline to PAUSED ...

Pipeline is live and does not need PREROLL ...

ERROR: from element /GstPipeline:pipeline0/GstAVFVideoSrc:avfvideosrc0: Internal data flow error.

Additional debug info:

gstbasesrc.c(2947): void gst_base_src_loop(GstPad *) (): /GstPipeline:pipeline0/GstAVFVideoSrc:avfvideosrc0:

streaming task paused, reason not-negotiated (-4)

ERROR: pipeline doesn't want to preroll.

Setting pipeline to PAUSED ...

Setting pipeline to READY ...

Setting pipeline to NULL ...

Freeing pipeline ...

What am I doing wrong?

Thanks,

Matt

1.9.1 is missing the following commit which would cause something like this:

https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/commit/?id=6de83e0515c334466f0e1649090c7421ea79881e
