Hi,
This seems strange to me, at first I'll need you to answer a few questions:

• Which branch do you use?
• Is pthread installed on your computer?

Hi,thanks for your answering.

1. the branch which i used is hevc rext
   2.i'm running on Linux 64bit
   3.the pthread have been intsalled on my computer. when i used the 4K8bit stream,the performace of decoder with the param -f 1 -p 4 has been improved obviously. i felt strange!

I tried on my machine and I can't reproduce the issue with both hevc and hevc_sdl2.
The display using SDL2 ( in hevc_sdl2) tends to slow down the main thread execution especially when trying to display large image. That could be the cause of your issue especially if the fps is really low
Did you try disabling the display ? (-n option)
Can you attach both hevc execution logs and the config.h generated by cmake so I can see if anything went wrong?
