I agree.  I am in favor of the default behavior being manual play of
media.

For the record, uninstalling the gstreamer1.0-plugins-bad package
solves this issue in Ubuntu 16.04:

$ sudo apt-get remove gstreamer1.0-plugins-bad

I don't really know, that's a webkit bug, surf doesn't handle video
playback.

Yes, set MediaManualPlay to 1.
I think I'll push it as a default.

[dev] [surf] freeze with gstreamer error

[Albert Cardona]

In web pages such as twitter.com, the following gstreamer errors
occur. The second one freezes surf.

(WebKitWebProcess:31459): GStreamer-CRITICAL **:
Trying to dispose element webkitwebsrc0, but it is in PAUSED instead
of the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
This problem may also be caused by a refcounting bug in the
application or some element.

(WebKitWebProcess:31459): GStreamer-CRITICAL **:
gst_mini_object_unref: assertion 'mini_object->refcount > 0' failed


Is there any mitigating strategy different than running with the -s
flag to disable javascript to prevent video autoplay (a dreadful
feature on itself, would be nice to disable it)?

To note that running with -p to disable plugins does not seem to
prevent video from playing.

Thanks,

Albert
