Providing useful GStreamer Zero copy issue reports

Important details about your platform

When reporting a bug please provide the following informations:

• GPU hardware and driver (if Mesa, provide version as well)
• GStreamer version (gst-inspect-1.0 --version)
• List of upstream and downstream GStreamer plugin sets installed (example: gst-plugins-bad, gstreamer-imx, gstreamer-vaapi)
• If Yocto is used, full list of meta layers used, Yocto release codename

Does it work in gst-play-1.0?

Check if this runs smoothly and doesn't use too much CPU:

gst-play-1.0 --videosink glimagesink /path/to/video.mp4

In WebKit

GST_DEBUG="3,webkit*:6" GST_DEBUG_FILE=/tmp/gst.log GST_DEBUG_DUMP_DOT_DIR=/tmp <browser> "https://..."

<browser> being for instance cog -P wl. In /tmp/ you should then see a series of .dot files and a gst.log file. Compress all of them in a single archive and attach it to the bug-report.
