Noticed this today, here's a screenshot:

The player was back in it's proper position when I disabled this CSS rule:

.player-height {
  height: 480px;
}

support sites using <object> tag to play YouTube videos.
e.g: http://www.mobafire.com/league-of-legends/videos

SOL 1:

http://player.ooyala.com/player.js?embedCode= + (e.g: 5tZjhoMToQ_42jg_5j_ES7AqaAZXQTQ4)

then match
var mobile_player_url="http://player.ooyala.com/mobile_player.js?embedCodes= .* &device="

and get url and append html5 and open

and if possible, match:
"http://player.ooyala.com/syndication/stream_redirect? .* "

and replace '\u0026' by '&' and open this video URL

SOL2:

open DASH video: http://player.ooyala.com/player/ipad/ + + .m3u8

ViewTubePlus is a UserScript alternative to Html5-video-everywhere with support for various sites.
http://userscripts-mirror.org/scripts/show/159658
https://heliotropium.it/ViewTubePlus.user.js

e.g:
ytplayer.config json contraining args.url_encoded_fmt_stream_map

and flashvars

e.g:
www.youtube.com/embed?listType=playlist&list=PL<PLAYLIST_ID>
www.youtube.com/embed?listType=user_uploads&list=<USERNAME>
www.youtube.com/embed?listType=search&list=<QUERY>

Youtube has a feature that keeps track of videos you watch when logged in to google account. This is very useful as you can skip over videos you've already watched in playlist or add only unwatched videos from subscribed channel.

VLCTube adds new item by calling the URL below. This could be used but its missing awful lot of youtube parameters that are sent with normal requests.

Some web browsers come with HTML5 Video Everywhere pre-installed but it is not always possible to locate it in the "Add-ons" list. Abrowser (part of Trisquel GNU/Linux) is a good example.

This makes it hard to know which version of HTML5 Videos Everywhere that is being used, a work around could be to add "About HTML5 Video Everywhere" in the context menu for videos.

YouTube HTML5 Video Player has "About the HTML5 Player" in the context menu when you mouse hover over videos.

HTML5 Video Everywhere description: "Replace video player with Firefox native video player."

Pr0n sites status

GNUzilla IceCat 38.3.0 (based on Firefox ESR) and Abrowser 41.0.2 (based on Firefox) tested. Both packages (icecat and abrowser) was tested from Trisquel 7 which can be downloaded from trisquel.info.

Asorted table.

1: Sometimes context menu: Streams with old proprietary HTML5 video players that was used in various Pornhub websites long time ago. Example, tube8 player without context menu: http://www.keezmovies.com/video/alexa-jordan-and-nadia-nitro-share-a-hard-cock-5737262. Example, YouPorn player with context menu: http://www.keezmovies.com/video/danejones-young-slim-shaved-brunette-s-romantic-fuck-4865762
2: Example: http://www.peeperz.com/fap-along-harlot-girls-glasses/
3: Non-HTML5
4: View Page Info → Media, sort by Type, select Video to get the video resolution

Non-free software issue

GNU LibreJS block non-free JavaScrips for all videos on all websites, HTML5 compatible or not. The next step is to replace non-free JavaScripts with free JavaScripts to play the videos.

HTML5 Video Everywhere cannot play xvideos.com and xhamster.com like ViewTubePlus. Implementing ViewTubePlus in HTML5 Video Everywhere is a solution. ViewTubePlus is a UserScript alternative to Html5-video-everywhere with support for various porn sites. Official download link: https://heliotropium.it/ViewTubePlus.user.js

"HTML5" includes Javascript and often the Javascript code is nonfree; GNU LibreJS block non-free JavaScrips for all videos on all websites. We need to replace those JavaScripts with scripts that is distributed under free softwares licenses. EvoVid.com is an HTML5 video sharing site that supports (exclusively) Ogg Vorbis and WebM. The site also supports the HTML 5 "save as" feature so that people can download videos from the site. To learn how to validate your HTML5 read https://www.fsf.org/blogs/licensing/rel-jslicense.

Pornhub NETWORK have been advised to support Firefox native player for all Pornhub NETWORK sites.

A good starting point would be to show this message in the video screen on all sites: To watch the video you need to enable Javascript in your browser. Currently this is only seen in xhamster.com, when GNU LibreJS is enabled.

add HLS support to the video player

Hello!
I gave this a try, but videos seem to only up to 720p.
Which suggests to me that that resolutions that are served via Media Source extensions are missing.
Can these be added?
Though disabled by default after enabling media.mediasource.enabled these are playable with firefox even on the stable branch.

The subtitle halts at 0:59:58 in this movie: https://www.youtube.com/watch?v=4M9K5ccBadE

The text "Recently there have been so many bad incidents around this area that I can get no customers here." appear for the rest of the movie on the screen.

ViewTube (http://isebaro.com/viewtube/?ln=en) can be used to play HTML5 videos from domains including:

• YouTube
• VIMEO
• VEVO
• dailymotion
• metacafe
• break.com
• funnyordie.com
• and some other.

Example:

works: https://www.youtube.com/embed/KlE1ovbPK0o
nope: https://www.youtube-nocookie.com/embed/KlE1ovbPK0o

the latter just renders a completely black page.

add MPEG-DASH support to the video player (throw dash.js?)

I do not find any option to turn on subtitles in HTML5 Video Everywhere! 0.2.30.

I've played videos in https://www.youtube.com/results?search_query=subtitle+movie but no text are shown in them.

How do I enable subtitles in YouTube?

lejenome@36cb361

Is possible to add youtube subtitles support?

the comment section under youtube videos will not load with this addon enabled.

Workarounds until a proper solution is implemented:

• use ViewTube userscript as proposed by @andrewpros
• use YouToube All HTML5 addon as proposed by @UhuruNUru

I tested HTML5 Video Everywhere! 0.2.32 on https://www.youtube.com/watch?v=4M9K5ccBadE for example.

"en" is pre-selected in the "Subtitle" list from the context menu or right mouse click, but nothing happens. If I now select "none" and then select back to "en" again, then the subtitle appear in the movie

like https://www.youtube.com/user/LoLChampSeries

Sometimes, you want to disable the HTML5 player, perhaps because the original player has more features, and you want to see a specific thing. In that case, it would be good to have a "Disable for this video" feature to reload the page without replacing the video player. It would be best placed on the context menu or a player button.

Brightcove Experience is a video platform used by some news websites (eg. http://tv.ilfattoquotidiano.it/)

The plaform itself seems to support html5, unfortunately the video producers choose to use flash only to stream videos :\

In html of pages containing Brightcove videos there are some "meta", eg.:

<meta property="og:type" content="video" />
<meta property="og:video:width" content="380" />
<meta property="og:video:height" content="280" />
<meta property="og:video" content="http://c.brightcove.com/services/viewer/federated_f9/?isVid=1&isUI=1&playerID=2274739660001&autoStart=true&videoId=4194558956001" />
<meta property="og:video:secure_url" content="https://secure.brightcove.com/services/viewer/federated_f9/?isVid=1&isUI=1&playerID=2274739660001&autoStart=true&videoId=4194558956001&secureConnections=true" />
<meta property="og:video:type" content="application/x-shockwave-flash" />

The property "og:video" might be interesting:

http://c.brightcove.com/services/viewer/federated_f9/?isVid=1&isUI=1&playerID=2274739660001&autoStart=true&videoId=4194558956001

That is redirected to (maybe a load balancer?):

http://admin.brightcove.com/viewer/us20150326.1403/BrightcoveBootloader.swf?playerID=2274739660001&autoStart=true&isUI=1&isVid=1&videoId=4194558956001

Wich is redirected to:

http://admin.brightcove.com/viewer/us20150326.1403/federated/BrightcovePlayer.swf?playerID=2274739660001&autoStart=true&isUI=1&isVid=1&videoId=4194558956001

From there, some network sniffing and/or reverse engineering is needed to understand how the URL of the stream is obtained...

e.g: www.youtube.com/apiplayer?video_id=<VIDEO_ID>&version=3

Fellow hacker.

IceCat is the GNU version of the Mozilla Firefox browser. IceCat comes with HTML5 Video Everywhere! inbuilt, an alternative to Flash player addons. Recently your software was added to the FSF's Free Software Directory: https://directory.fsf.org/wiki/HTML5_Video_Everywhere!

But there are a little problem I hope you can help us with. https://github.com/lejenome/html5-video-everywhere/blob/master/README.md says: "YouTube signature decoder code (data/flashgot-YouTubeSwf.js, lib/flashgot-YouTube.js) was copied from the GPL licenced flashgot extension with some code removed and other added code under the same licence.".

data/flashgot-YouTubeSwf.js does not have any copyright or license information in the top of file and there is no copy of the GPL alongside this file. Additionally, I do not know if other files interact with the flashgot-YouTubeSwf.js file in such a way that they would consittute a single combined work under the terms of the GNU GPL. If so, then the program as a whole would need to licensed under the terms of the GPL. I fyou could please update the header files and the license notices that would be greatly appreciated.

Thank you in advance.

e.g:
metacafe.com/<CHANNEL_NAME>

http://www.abc.net.au/4corners/stories/2015/02/23/4183437.htm

Is anyone else able to replicate this? Just play the video and then pause it. If you spam the pause/play button, you'll get lots of concurrent audio playing.

Thank you for this extension.

Since YouTube starts to use HTML5 player for most videos on modern browsers by default (http://techcrunch.com/2015/01/27/youtube-goes-html5-flash-is-now-deader/) and I prefer the original YouTube HTML5 player, it would be good to provide a setting to disable the substitution on specific sites.

The Firefox add-on Media loop is described as a "Menu item to control [HTML5] audio/video loop" - https://addons.mozilla.org/en-US/firefox/addon/media-loop/. Media loop can be used to repeat HTML5 videos on any website, not just YouTube.

Can you to implement Media loop in HTML5 Videos Everywhere! and a Repeat button that uses it in Control. Refer to the red marked repeat icon located bottom right at the above modified screenshot?

HTML5 Video Everywhere is currently part of GNU IceCat, if we add the repeat button there is a great chance that other developers add the repeat button to their web players.

e.g:
vimeo.com/moogaloop.swf?clip_id=<VIDEO_ID>

Go to http://www.mobafire.com/league-of-legends/videos and play a video, it try to use flash player instead of html5 (i have shumway and try to use it).

It would be great if you can add support for Giant Bomb's video player.
Example: http://www.giantbomb.com/videos/quick-look-life-is-strange/2300-9890/

Thus saving me the trouble of getting the .mp4 link from the page source of each video.

Youtube HTML5 Video Player (https://addons.mozilla.org/en-US/firefox/addon/youtube-html5-video-player/) is named after the exact same title as YouTube's integrated Youtube HTML5 Video Player, this is confusing.

Please rename "Youtube HTML5 Video Player" to "Youtube HTML5 Video Player-libre" or something that makes the name unique.

Please, update FSF address in flashgot-YouTube.js .

Drivers can not get preferences until all code outside Events callbacks terminates including code inside Promises.

As result, Driver with defaults exporsts.when will not be able to access preferences because onReady() will not use the Event callback and Promises will not works. So, currently all Drivers need to move to exports.when = "start" and wrap the needed part of its code inside onReady() funct

e.g: this will affects getPreferredFmt() funct and all code needing access preferences

It doesn't seem to work on facebook, both in video page and on timeline. Anything else I should be doing for it to work? Tried disabling flash plugin and restarting to force it using the addon but no difference. In youtube it's working properly

Starting from Firefox ESR v38, JPM will replace CFX.

These items are found in YouTube HTML5 Video Player context menu.

• "Get debug info"
• "Report playback issue"

You will get more bug reports if you add them to the context menu of HTML5 Video Everywhere.

What is the difference between?:

• Youtube HTML5 Video Player - https://addons.mozilla.org/en-US/firefox/addon/youtube-html5-video-player/ - Home page refer to https://github.com/lejenome/html5-video-everywhere
• HTML5 Video Everywhere! - https://addons.mozilla.org/en-US/firefox/addon/html5-video-everywhere/

e.g: www.youtube.com/watch?v=<VIDEO_ID>&t=<TIME_VALUE>

e.g:
vimeo.com/couchmode/user<USER_ID>/videos/sort:<SORT_TYPE>/<VIDEO_ID>

Redirect Flash SWF file request (flash player inside <object> tag) to a custom SWF file that replaces its <object> and <embed> tags with an <iframe> with src set to the HTML5 embed version.

This will be useful on recent verions of Firefox with Shumway enabled and when a site uses an embed code from the streaming site that contains <object> or <embed> tag.

This Flash program should be generic, so could be used by all drivers (Facebook, Vimeo,..). And, it should read parameters from its URL query params.
It should be too light and support most of open source Flash implementations (Gnash, Shumway, Lightspark).

As title says.
This is a very annoying issue for me, as volume always starts at the highest.

• The volume isn't remembered as a default setting - not referring to the setting the volume from the settings.
