Since v38 has forced HTML5, I can not watch a single video now.  I have had this problem for a while and cant find the culprit.

Only way I can watch a vid is via Flash.  Furthermore, if someone were to embed a video from Youtube into a webpage in neowin, I would not be able to watch the vid, I would have to go to YouTube to watch that video... via the default flash player... but now, that isnt an option.

When I click on a video, I get the white-ish grey circles rotating, but it never stops, and the video never starts.  If I hover over the placemarker to advance somewhere in the video, I see the little thumbnail over the placemarker, but when I click Start - nothing happens.

I have disabled addons to see if that was causing it - no change.

 

I have switched to Chrome now, but would rather FF work correctly.

Anyone have any ideas ?

Thanks

I guess that's what happens when you want to run beta software! ;)

 

Expect issues and bugs.

It was the same with 36, and 37.

If you read my original post, you will see I mentioned it has been an issue for a while, but before I was able to select the default flash player.

 

Yep, it's YouTube's way of saying "What is wrong with you? Why are you watching Ariana Grande stuff?"  :laugh:

I was wondering if someone was going to comment on that - it was on my main page - I like the Jimmy Fallon stuff ;)

Have you tried an add-on like the one below to force videos to play with Flash Player?

 

https://addons.mozilla.org/en-US/firefox/addon/youtube-flash-video-player/

Yes I did - unfortunately no difference.

Here is a weird update....

I clicked on a video and instead of seeing the circles rotate then do nothing - I just sat there, and after about 10 seconds, the video started to play, then stops after 1-2 seconds with an error.

I click on the "about this error" and it says there is no information about the error.  I went to YouTube's TestTube site, and tried the new player - no difference.

I will try the tips mentioned here

Thank You

 

FWIW - I also loaded the new player (I think its supposed to be tweaked for 4K @ 60 fps, and HD stuff - it performed perfectly on chrome - I like the new look of it too, even if it is subtle.

OP - just throwing my 2c out there. I have the latest official build, v37, and have zero issues with Youtube. I even tried that Test Tube stuff you linked us to. It works great.

 

What i could try is v38 in a VM... i just think your computer might have another underlying issue that isnt related to FF directly.

It sounds like the "mediasource:" script is being blocked on your system. Do you have a script blocker like noscripts installed? If so you need to allow "mediasource:" and then on youtube I think it will be "googlevideo.com" will show up and that will also need to be allowed to run html5 video's on youtube.

I don't think that newest versions of Firefox have MSE enabled by default, even on Windows.

 

You can check if your browser supports MSE extensions here https://www.youtube.com/html5

 

Anyway, to manually enable this feature, you have to go to address:  about:config

 

find the key: media.mediasource.enabled

 

and set it from false to true.

 

That should fix your problems.

I use ublock, and disabled it and no difference

v37 & 38 are completely compt with MSE and I already hate that tweaked in about:config

Thank you though

 

Just tried v38b on a Windows 10 VM. No issues w/ the standard player or the 'new' player.

Thanks Jason - I appreciate you going through all that just to help me.

UPDATE:

OK, this is just weird - now it works!

I havent been able to get it to work for a week or 2, now - suddenly it works through the new player

However, I want to use my addon that automatically selects the highest res the video supports - and it isnt working.

But that is easy to fix with a different addon - the main thing is now I can continue to use FF

This is one of those times where you are totally confused as to why something stopped working, then started working again, but you dont care because it is working....  :D

^ What addon was that? I use YouTube Center (the developer version) to always select the highest quality: https://github.com/YePpHa/YouTubeCenter/wiki/Developer-Version

 

Have no issues on Firefox 38 the latest beta (9 I think). Not with the new player or the old one (all html5, for the 60fps support).

    • HONOR Robot Phone unveils first Cinematic Video at Shanghai International Film Festival

      By Steven P. · Posted

      HONOR Robot Phone unveils first Cinematic Video at Shanghai International Film Festival by Steven Parker Global AI device ecosystem company HONOR announced on June 13 that its revolutionary HONOR Robot Phone made its professional imaging debut at the 28th Shanghai International Film Festival (SIFF), demonstrating the result of its mobile videography capabilities for the first time. As the official mobile photography and videography partner of the 28th Shanghai International Film Festival, HONOR empowers this premier cinematic event with cutting-edge mobile imaging technology. Marking the global debut of the first cinematic video it captured, Robot Phone breaks down the boundaries between mobile imaging and professional filmmaking, ushering in a new paradigm for the deep integration of technology and cinematic art. In the video published on HONOR’s official channel (above), Robot Phone was used byELLEMEN to capture cinematic video portraits for the SIFF jury members. With its exceptional stability and cinema-grade imaging capabilities, the device redefines the art of portrait filmmaking, faithfully reproducing the rich tonal gradations and nuanced color transitions associated with film photography. The result is a new level of visual sophistication, creating high-end cinematic imagery that seamlessly blends atmosphere with narrative tension. The video released for the Robot Phone showcases the powerful stabilization capabilities of its built-in gimbal system, delivering exceptionally smooth handheld camera movement while preserving full image quality. By minimizing reliance on electronic image stabilization, the device effectively avoids the image cropping and quality loss typically associated with digital stabilization methods. Representing an innovative leap in form factor, the HONOR Robot Phone features the industry's smallest titanium alloy gimbal, delivering ultra-precision, extreme flexibility, and superior stability. Driven by high-performance motors, the gimbal rises dynamically, breaking free from the physical limitations of traditional camera modules. Combined with advanced AI algorithms that enable intelligent object tracking and various movements with stable shots, the device significantly simplifies video creation and reshapes both the equipment choices and creative habits of modern users. Notably, the Robot Phone will be the first product that features the results of HONOR's strategic technological partnership with ARRI, the world-renowned designer and manufacturer of professional camera technology for cinematic storytelling. From Cannes to Shanghai, the HONOR Robot Phone continues to lead the mobile imaging industry into an entirely new stage of development. Moving forward, HONOR will leverage cutting-edge AI and mobile imaging technologies to unlock new creative possibilities and extend cinematic standards for visual expression from the world of high-end filmmaking to the next generation of content creators.

      I'll wait for the root cause analysis. Looks like it's HP, Lenova, and certain configurations that are askew, hardly "all of windows." Time will tell.

      I had issues with my NVME, it was running really slow (like 2/3 mb bandwidth) ... had to reverted via System Restore and all is fine now.
