Hey. 

I'm testing a plugin and noticed that on different OS Kodi is expecting different buffer sizes. 
I'm only taking into account default configurations, without advancedsettings modifications. 
Looking into the code, but not so familiar with c++, so it's hard to trace buffer size setters. 
Talking about the one buffer size, which is expected when this message is thrown:

WARNING: CRenderManager::WaitForBuffer - timeout waiting for buffer

Can you give some advice where to look?

Am I correct there is no RPC/Python call to get current buffer setting?

Looks like it's Player related stuff, so currently i'm exploring VideoPlayer, but still can't find relevant place in the code. 
Have a feeling that media type of video is influencing as well.

The size of the render buffers depend on the decoder and renderer. The warning indicates that there is no free buffer. The main reason for this warning is that something blocks the main/render thread.
