Re: Youtube Download Slowing Down Causing Buffer possible CDN issue

Hello, Community.

 

A quick update, we are still in a pursuit of the resolution. Thank you all for your continued patience. 

 

@futurelgcy & @xuelide - May I ask you both to upload the 4K stream recording video as you have done earlier like in the Message 139 and Message 141

 

I look forward to the video uploads. 

 

Cheers,

RogersMoin

Hello, @futurelgcy.

 

Thank you for promptly uploading the videos. BTW, only the second link has the video while the first link is a tutorial. 

 

Community - We are looking for more examples. Please turn on "Stats for Nerds" on the 4K stream which may be buffering for you, capture the video and upload it. 

 

Cheers,

RogersMoin

Hello, @futurelgcy.

 

Thank you again for uploading many more videos. I'm looking for time stamp for those videos. The first three videos posted above, are those from today?

 

Cheers,

Re: Youtube Download Slowing Down Causing Buffer possible CDN issue

@futurelgcy@RogersMoin, personal opinion, there's something a little strange here.  According to the data in the uploaded video, your monitor is running in 1920 x 1080 resolution.  Your download video is running in 3840 x 2160 resolution, twice the current resolution of the monitor.  When I ran the video in 1920 x 1080 to match the monitor resolution on my old clunker pc that I use for email and web cruising, it runs without issue.  The minute that I switch to 3840 x 2160 download, I end up with the same situation.  That makes sense as the pc or video card has to downgrade the incoming video stream to the maximum monitor resolution.  I don't know where that conversion takes place, in the CPU or the video card, I suspect its the video card.  In that case, my card most likely wouldn't have anywhere near the horsepower to do that.  That might be the same for a vast number of video cards.  

 

So, my current view is that you would have to run that resolution on a monitor and video card that is capable of supporting 3840 x 2160.  Until you're there, you can't say that the problem is on the Rogers side.  

 

What resolution is your monitor and video card capable of running?  They would have to be set to run 3840 x 2160 prior to starting a video of that resolution.

Re: Youtube Download Slowing Down Causing Buffer possible CDN issue

@futurelgcy - I certainly understand your point that it's not working 99% of the time. However, we need the timestamp for the videos for investigation purpose. If you can record it now with Viewport set at 3840 x 2160 and upload the videos with the timestamp, it would be very much appreciated. 

 

@Datalink - The first 2 videos have the Viewport at 1920x1080 whereas the other four videos have the Viewport set at 3840 x 2160. 

 

Cheers,

RogersMoin

Re: Youtube Download Slowing Down Causing Buffer possible CDN issue

ah, ok, the last videos weren't posted earlier today when I had a look at this.  

 

@futurelgcy is 3840 x 2160 a native resolution for both the monitor and video card, or do you have to over-ride the supported resolution selections to access the 3840 x 2160 selection? 

 

Looking at the videos:

 

3840 x 2160 @ 60 have problems

3840 x 2160 @ 30 run fine

 

So, in addition to the resolution question above, whats the maximum native resolution for the monitor and video card, some lower resolution, or, 3840 x 2160 @ 30 or 3840 x 2160 @ 60?
