Windows Chrome and Processing Latency

[sanalpencere]

I am not hundred percent sure this issue is related to jmuxer. I appreciate any guidance you might offer.

We're using jmuxer for live streaming. Our streaming machines have two types of encoders. One of them is Nvidia, another one is OpenH264.

The problem is with Chrome on Windows. I think that processing takes a long time and it causes latency. But the weird part is if I close hardware acceleration from Chrome settings. There is no problem. Also If I use OpenH264 encoder, there is no problem too. Also If I force Windows to use the Nvidia graphics card for Chrome, There is no problem too.

Let me give you our encoder settings too:

NVIDIA

• Bitrate: Between 4Mbit - 16Mbit (It is optimal)
• Profile: Main
• Preset: LowLatencyHighPerformance
• RC Mode: VariableBitrate
• FPS: 30
• IdrPeriod: 10
• QP: 20
• Target Quality: 20

OpenH264

• Bitrate: Between 4Mbit - 16Mbit (It is optimal)
• Profile: Baseline
• Usage Type: SCREEN_CONTENT_REAL_TIME
• IdrPeriod: 10

It seems to be a similar issue #84
Also, there is a difference in profile. Can you try with baseline profile when you use NVIDIA to be sure if it is related to the problem?

Of course, I will try it again. I remember I tried with Baseline profile and got the same problem. I will try it again to be hundred percent sure.

The most annoying thing is also when I close hardware-accelerated decode from chrome flags. The problem is gone.
