Status: RESOLVED INVALID

(Core Graveyard :: Plug-ins, defect)

Description

[Souza Perez]

Attachment: error 1.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150402191859

Steps to reproduce:

I was trying to access one of the videos from http://mais.uol.com.br/ specifically http://mais.uol.com.br/view/dt38ct3datkc/15445313?types=A&.


Actual results:

The error message page of Uol Mais servers is that this video is not compatible with this computer or device.
Previously, it worked with the old Flash Player, although I prefer this new HTML5 version because so far not resulted me no crashes. Just this mere incompatibility that I hope you guys correct it asap with new Firefox versions. Google Chrome can view these videos perfectly, although always I preferred use Firefox.


Expected results:

Expected load any HTML5 videos without any error.

However, should not be restricted to the disposal to solve this problem, since I can't access to my favorite series and furthermore, I've constantly depended on the use of Firefox. Just take a look on the links below:

The sites require Flash Player. Disabling Flash Player in H.264-enabled Chromium results in the exact same error message for the first site, and a similar browser plug-in placeholder for the second site. So there's no HTML5 video on those sites: it's just that Chrome has Flash Player built-in. For Firefox, it has to be installed separately.

Contact the site owners and ask them to correct the error message. It should say Flash Player is required.

Contact the site owners and ask them to migrate to HTML5 video.

Oh, please, I'm sorry for my confusion. I just thought Firefox reached the same standards as Chrome, at least came pretty close.

Well, I guess I don't have much choice but to do that you recommended me then. Even though...

I think that developers might well do the same with Firefox supporting Flash Player in H.264 as you said, already built into the browser itself. Well, that's just my guess.

Anyways, in the end it seems that just everything is working like a charm. Thank you Gingerbread Man.

Work is progressing on project Shumway; once completed, it should allow playback of Flash content without Flash Player.
