1167260 - support for rewinding HTML5 videos

Status: UNCONFIRMED

(Core :: Audio/Video: Playback, defect, P5)

Description

[Elmar Stellnberger]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150513174244

Steps to reproduce:

View http://www.elstel.org/html5video/Html5VideoScripting.html.de with three different browsers.


Actual results:

While the rewind function worked well with Safari and Qupzilla it does not work with Firefox, yet.


Expected results:

It would be very nice if Firefox supported scrolling back HTML5 videos via setting a negative playback speed by Javascript.

Browser Console says
  NS_ERROR_NOT_IMPLEMENTED:  Html5VideoScripting.html.de:163:0

which points to
  video.playbackRate = rate;

As far as I can see, I don't find many websites using negative playback speed. However, I could be wrong. Please share them with me if you find some or there are other use cases you need to use negative playback speed. Thanks.

Make it as P5 before we can better know the values user can get.
