Netflix videos not playing/recording in real time?

[zekeblue]

Wanting to know if this is normal. When downloading/recording a Netflix video, it plays jerky and takes approximately 2x as long as the length of the video. It doesn't matter if I play at normal speed or 1.5x. The resulting file plays fine once done though. The QDrmCef,exe file is using ~65-75% of a Core i7 CPU on Win 10 x64.

Thanks........Pete

Hi,

DRM Downloader also encode the video to MP4 file when playing back the movie, I suggest that you get a NVIDIA GTX 10 series card to use the GPU to encode the file.

It's using 20% CPU only when playing back the video in 2x speed and also playing back smooth. Using i7-6700, GTX 1050 Card.

And also please confirm that the driver is installed for your intel HD card. (You can also send me the info from the free tool CPU-Z, we will check it)

Thanks!

Are you suggesting that what I am experiencing is normal for most mainstream PCs, or at least PCs without a discrete graphics card? To other users..... are you experiencing this?

do you have your computer connected to WIFI or are you using Ethernet cable ??
might try signing in to Netflix, select your profile, select account, under profile, select playback settings ,
under data usage, select High, select save, and retry Netflix again to see if the video quality settings improve.

Thanks for chiming in.

Wifi, but bandwidth use is pretty low. Nowhere near the wifi's capacity. Playback settings in Netflix are already on High. It is the processing of the video within my computer that seems to be the bottleneck. 70% CPU use. From your response, it sounds like this should not be the case.

especially if you anything other than windows defender.

I'm using Defender plus Malwarebytes. I can give it a try disabling. I'll be back!

Edit: No difference. Are you running with integrated graphics and having a smoother experience? I wish a few others could confirm or deny the problem. If it is expected, I'll have to live with it. If not, I'll troubleshoot in earnest. Thanks.

what web browser are you using to watch Netflix on ??
if not already, you might want to use Firefox.

Hmm. I'm using the one built into DRM Downloader. Firefox is my regular browser. I didn't realize you could do the downloading while playing in a different browser. I'll try it.

Edit: Can't see a way to download in DRM if playing in Firefox. Did I misunderstand you or am I missing something?

Hi,

I confirmed that it's the bug of DRM Video Downloader, the Intel GPU is not used when encoding the files.

Please wait the version and it will be fixed.

Thanks!

Hey, thanks! That was quick troubleshooting behind the scenes. I can stop worrying about it now.

Tried 3.0.0.3. Doesn't look like this fix is included yet. 1x, 1.5x or high speed download switch make no difference in download speed. Video is still playing jerky and CPU still at ~70%, but at least it is recording the video in approx the same time as its length instead of twice as long!

does your ISP have some sort of speed / download cap going on ??
might try connecting to Ethernet cable and see if you get the same download speeds

Thanks, but since Wilson says it is a bug in the program, I will look to my system only if I'm told it has already been fixed. No ISP speed caps. Getting >25Mbps on my laptop with wifi. CPU is the bottleneck.
