Why don't we just click to play everything?
Yes, we should do that. At least as an option, exposed in Preferences:
something like
[ ] Never auto-play video or audio
or
[ ] Always show a Click to Play control for media
I'd suggest it belongs in Preferences / Content, right along with "Block
pop-up windows". Auto-playing videos (or audio) can be every bit as
irritating as popups.
To quote from a long-time Firefox user's recent blog posting[1]:
# Give me a 'Play' button, and let me decide when (or whether) to click
# it. If you can configure Firefox - or allow me to configure it - so
# that it will never on any site, ever, no not even then or there, play
# a video without waiting for me to click on a button clearly labelled
# with a right-pointing arrow head of some sort... that would be a
# victory.

Sending this because piman@ thought it was a good idea.
*Contact Emails:*
gr...@chromium.org, tommy...@chromium.org
*Spec:*
A specific portion of this design doc:
https://docs.google.com/document/d/1GQ-B3gWyWYX1cXf_B8mTK2ELSVwHqT-5bAERZqPliCo/edit#heading=h.bea8i8zdwtn7
*Summary:*
Plugin Power Saver "pauses" plugins deemed to be peripheral (small,
cross-origin). This feature is to allow web authors to specify a poster
image to be used in the "paused" state.
Usage:
<object data="http://b.tommycli.com/flash.swf";
type="application/x-shockwave-flash" width="400" height="100">
<param name="poster" value="snapshot1.png" />
</object>
*Motivation:*
Without a poster image, Chrome tries to automatically extract an
"interesting" keyframe during a short preroll.
- Plugin start can be deferred if there's a pre-provided poster image.
Better performance for users.
- If Chrome tries to extract a keyframe by analyzing frames, it could
choose mediocre frame to use.
- Keyframe extraction process itself takes up CPU time.
*Link to Intent to Implement:*
I implemented this before I was aware of this process. I sorry. It's behind
a content setting though, so no users will experience it unless they
explicitly opt in.
*Demo link:*
Use Chrome Canary. See http://a.tommycli.com/small_only_poster.html
See here for a video:
https://drive.google.com/open?id=0B-Use9bxumRNZE5Ub2VGYTk0c1E
*Compatibility Risk:*
I think it's minimal. The param tag is already supported. The 'poster'
parameter continues to be passed to the plugin, it's just re-used for a
different purpose. We could call it webkit-poster or something if you guys
are worried, but I'd prefer not to. If we take the feature away, the
browser will just ignore that parameter, and it shouldn't break anything.
*Ongoing technical constraints:*
None that I'm aware of.
*Will this feature be on all platforms?*
Windows, Mac, Linux, ChromeOS. Only the platforms with plugins.
*OWP Tracking bug*
None. Happy to make one if you guys want.
Link to entry on the feature dashboard <http://www.chromestatus.com/>
Also none, but happy to create also if you guys want.
