How to reduce cpu usage of TotalCode Studio?

[Ganten]

I use the following ffmpeg command to convert the video:

Code:

ffmpeg -hwaccel qsv -c:v h264_qsv -i input.mp4 -c:v h264_qsv -b:v 5000k -c:a copy output.mp4

It just use 15% cpu and 60%-70% gpu to convert the video.

TotalCode Studio use nearly 100% cpu and the same percent gpu to convert the video even I use IQSV mode and DirectShow.

How to reduce cpu usage of TotalCode Studio?

Thanks for helping.

Hello Ganten,

First of all, I have to admit that TCS does not support IQSV hardware accelerated decoding, while FFMEPG can use HW decoder. Also, in the earlier versions of TCS we had an issue with a high CPU consumption during decoding process, but it’s fixed in the latest version. Which exact version are you using now?

It would be helpful if you can clarify more details, such as:
- which DirectShow decoder is it?
- which output preset was used for encoding?
- can you send us your input stream or a screen shot of the input stream parameters? 
- please run the transcoding process, and after that find and send us a log file, by default it is stored on your desktop (TotalCodeStudio.log).

You can upload files or screen shots by this link (size limit is 4GB).

Once we receive this information, we will investigate it and provide our recommendations.

Thank you.
