Description George Chriss 2015-07-18 22:47:12 UTC 
Web Content Accessibility Guidelines 2.0, Guideline 2.3 recommends "freezing the image momentarily if 3 flashes within one second are detected" to prevent potential seizures or adverse reactions to viewing media.
See: http://www.w3.org/WAI/WCAG20/quickref/#seizure

I'm fairly certain flashing-image-detection is unimplemented in any of the existing gstreamer plugins and this is particularly important when considering live-broadcasting applications.

Do you intend to work on this?
Comment 2 George Chriss 2015-07-18 23:26:37 UTC 
Out of necessity, yes.  I've live-streamed several conferences with simultaneous viewership counts in the mid-hundreds, some of which include desktop-based video streams which are more likely to induce seizures on account of rapid window switching.

At least one viewer (who was unaffected) was watching a live video stream in mid-flight.  Other viewers use smartphones which typically don't have rapid flashing as part of the UI -- the risk exposure is watching the live stream itself.

A high-profile incident:

I've read through GStreamer's technical documentation but I haven't developed a GStreamer plugin before.
