<div dir="ltr"><pre>Hello to all! I set up environment in Tizen IVI 3.0 M2 for my Intel e38xx based board with recomendations from <a href="http://www.intel.ru/content/www/ru/ru/intelligent-systems/bay-trail/tizen-ivi-m2-kernel-ltsi-linux-support-package-atom-e3800-gsg.html">http://www.intel.ru/content/www/ru/ru/intelligent-systems/bay-trail/tizen-ivi-m2-kernel-ltsi-linux-support-package-atom-e3800-gsg.html</a> (january 2015 revision). Video playing and camera streaming works through gst-launch-1.0 pipeline (displayed on wayland surface). I need help with some issues. First of all, then i tried to open the camera in webkit html app in <video> tag through GetUserMedia with all needs privellegies, i don't see the stream from camera, although the lamp on the camera is lit, which means it opened succesfully i think. Below a log, when i try to open camera from trough GetUserMedia: Jun 18 06:54:25 localhost wrt_launchpad_daemon[182]: launched Jun 18 06:54:26 localhost wrt_launchpad_daemon[182]: (WebProcess:259): GStreamer-WARNING **: 0.10-style raw video caps are being created.

May be this problem is in webkit browser, that displays html application, or Gstreamer didn't have some sink to attach video to webkit window? P.S. Versions of software, that i used: libdrm-2.4.45, mesa 9.2, libva-1.2.1, intel-driver-1.2.1, gstreamer 1.0 with base-good-bad-ugly plugins, gstreamer-vaapi-0.5.9. Thanks for any help, Best Regards, Maks.</pre></div>
