You should check ffmediaelement: https://github.com/unosquare/ffmediaelement
It is quite good, however not maintained anymore.. it is using ffmeg 4.x

And you should check your code with memory profiler. You should not allocate any object during the the play (after initialization of course)
And you should avoid copying the decoded frame's pixel data. (so decode directly to the required destination memory area)

I'm decoding several fullHD (or bigger) H.265 streams without any noticable cpu usage.

Closing it now, they are even example does it.

ok, sorry,

actually i have implemented everything already: demux, decoding, rendering are seperated into different thread.
but just the performance is not very good, it takes some extra CPU, so i wanna know some suggestions.

actually i guess i can't avoid to copy pixels from ffmpeg, because i need to upload the frame pixels decoded by ffmpeg to OpenGL, i used PBO to upload.
not sure if there are some ways out there to map ffmpeg frame pixels to OpenGL FBO/Texture directly in the back without dealing with CPU?
anyway thanks for your suggestion, i'll dig into this project to find how it renders.

I think the better you describe the problem and why you need solve one is a key - we might but cannot guess 100% here, as fairly cheap memory to memory copy is not would you can expect in real life as you talking about GPU, has nothing to do with this project rather than expectations.

ok,~ thanks anyway! 😉

@jcyuan https://github.com/SuRGeoNix/Flyleaf look this,DirectX instead of OpenGL ，I am also interested in opengl
