Processor Capability Issue

[Sowmiya_S]

I am using core i5-10500TE (16gb ram) as a processor and Intel(R) UHD Graphics 630 for video processing. While i try to (video)screen capture at 4K@60fps using FFMPEG it is showing as buffer full error. When we executed FFMPEG command it encodes and save the live stream as MP4 format into the SSD. Using below FFMPEG command. But it always returned with buffer full error within 4 to 5 sec even we tried to save raw data to SSD as.YUV format that time also it showed the same error. It is showing the allowed max buffer size is 2147.6M like that. Below I have posted the FFMPEG command which I used

ffmpeg -y -f dshow -video_size 3840x2160 -framerate 60 -rtbufsize 2146.7M -i video="UPG761 HDMI, Video 01 Capture" -c:v libx264 -preset ultrafast -tune zerolatency -b:v 250M -minrate 250M -maxrate 250M -bufsize 250 4ktest1.mp4

This is Buffer Full Error we are facing.

Whether my processor has capable to run 4K@60fps kindly provide us with a solution

Hello @Sowmiya_S,

Thank you for contacting Intel Embedded Community.

Looking at the processor's specifications it supports 4k@60 Hz.

You may try looking in other communities, as you are using third-party tools.

I think you can try different configurations to begin with and then test what works and what doesn't, you can check with a lower resolution or another encoding, also, or the capture card.

I found this too, I hope it may be of help.
