Q: Safari doesn't play my 60fps videos uploaded on YouTube. Chrome does.

Since a couple of months I can't playback 720p 60fps videos in Safari (latest Version 9.1) on El Capitan (latest Version 10.11.4), but I believe this happened on Yosemite as well. I used to playback them with no problem some time ago.

 

As I open the video on YouTube, I'm seeing the first few frames of the video and then it stops because it lacks cached data – with the loading icon, buffering timelessly. If I switch down to 480p for example, it suddenly runs and buffers with no problem.

 

I'm uploading MOV files with ProRes codec, but MP4 files with .H264 act the same. No problems watching my videos on Chrome! Also no problems with same videos, but in 30 fps version.

 

Also I CAN watch other 720p 60fps videos on YouTube in Safari with no problem. What's more weird is that I cannot run 1080p 60fps smoothly anymore, but some time ago they worked well – not the same problem like with the buffering described above, but with video performance (they run about 3 fps) – maybe that has something in common?

 

I've got a MacBook Pro (15-inch, Mid 2010) – I know it's old, but it plays 60fps HD videos in Quicktime with no problem. Graphics card NVIDIA GeForce GT 330M 256 MB. I've got a known GPU factory flaw diagnosed at Apple retail store (but the Apple repair program doesn't cover my model) that causes sporadic spontaneous computer restarts. May that have something in common as well?

 

Any clue is more than welcome!

 

EDIT:

Don't know if it helps, but this is what I mainly get in the console:

25/05/16 20:37:24,968 WindowServer[187]: _CGXRemoveWindowFromWindowMovementGroup: window 0x2557 is not attached to window 0x2583

    Hi,


    "No problems watching my videos on Chrome"



     

    Update OS X to v10.11.5 and Safari 9.1.1 then see if the problem persists.

     

    Open the App Store then select Updates from the menu.

     

    Try a video after the updates are installed.

    Thank you for reminding me about the update. Unfortunately it didn't change the situation a bit.

     

    EDIT: If I tap on the progress bar, to change the time position of a video, I'm able to watch a few seconds, but the buffer stays very short and eventually the video stops due to the lack of data, so it looks like a problem with correct buffering.

    Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items.  Quit/reopen Safari and test. You can also try try Safari/Reset Safari. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then Library./Caches/com.apple.Safari/Cache.db and move it to the trash.

     

    Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

    Eric, thank you for your suggestions, but:

     

    Empty Caches – didn't help

    Safari/History/Show History and delete all history items – didn't help

    Safari/Reset Safari – no such option

    Library./Caches/com.apple.Safari/ – removed whole folder and it didn’t help

    turning off extensions – didn't help

     

    What I’m getting recently in the console when trying to play that YT video is:

    31/05/16 11:40:15,213 com.apple.WebKit.WebContent[5249]: HDDec_Thread_HWSliceDecoder_SampleID: CreateGPUInterface renderer 1040008

    31/05/16 11:40:15,218 com.apple.WebKit.WebContent[5249]: ava error: InitDriver call failed, call DeleteDriver ...

     

    I've found this in Safari error console:

    ReferenceError: Can't find variable: safari


    Blocked a frame with origin "https://www.youtube.com" from accessing a frame with origin "https://plus.google.com". Protocols, domains, and ports must match

     

    Googling which leads me to other people's problems with 60fps videos, but not many and not too similar.

    I have the same problem. Youtube 720p / 1080p 60fps just will not play in Safari - but plays fine in Firefox.

     

    I have a late 2013 Macbook Pro Retina with 8Gb RAM running 10.11.5 and Safari 9.1.1

     

    Anyone found a solution to this yet?

    I am having this exact same issue. Been pulling my hair out for the past two days trying to figure it out, but nothing fixes it. Chrome plays back the videos that Safari will not. This has to be a Safari issue.

    I'm having the exact same problem. Same messages in my error logs. It's something to do with Safari for sure, and YouTube, I suppose you could say. It's doing it on both of my Macs. None of the above solutions work. On occasion it works. Seems like with older 60fps videos it works.

    Does anyone know of any way to report this to YouTube, or Google? This is driving me crazy and makes no sense at all. Like I am sure some of you have noticed, older 60p videos seem to playback just fine. It is just when uploading a new one that it doesn't work. Just sits there and buffers... Hello, anyone out there listening???

    I have the same issue. I uploaded a 720/60fps video onto youtube and it won't play in Safari. Plays fine in Chrome and Firefox. Very annoying. I believe it's an encoding issue on youtube's end and not much can be done on your mac.

    I am sorry, but this is NOT a "solution". You cannot expect people with stable working machines to update to a completely different OS. Take me for an example. I am running Yosemite in a recording studio that uses Pro Tools that is seemingly only totally stable at 10.10.5 Not to mention the hundreds of plugins I have installed on my system that are most stable at 10.10.5 as well. I wouldn't dare jump to Sierra. Heck, I won't even go to El Capitan. Sorry, not a solution. The solution is for whomever the issue lies with, be it Apple or Google (YouTube) to fix it...

    I hope you are right and that this is an encoding thing on the YouTube side, because if it is a Safari thing then I might be in deep trouble. I am running 10.10.5 Yosemite, and I plan on staying here for a long time. Has anyone tried to reach out to YouTube? Is that even possible? I have looked and find no real way to contact them.
