In my many years of using FFmpeg as a library and as a tool I saw a lot of 
people who build FFmpeg 
on they own as I do. One, but not all reasons for a custom build is desire to 
debug whole application 
with one tool and on Windows many people still use Visual Studio so they make a 
build with VS, 
which is not available in places like zeranoe. 
Another reason is to make minimum feature set needed to their app.
At the same time for many real-time applications a software encoder is not an 
So these developers will appreciate default support for both GPUs. Everything 
related to 
game streaming (OBS), DVR, could gaming, wireless virtual reality etc. are use 
cases and real users behind.
Again we are talking about ease of access, not about impossibility.
I would like to see that people set few parameters and encoding would happen 
without additional going through hoops.

I also noticed that recently there is a lot of activity to add full Nvidia 
decoders  to FFmpeg (VC1, MPEG4, VP8, VP9 etc.). 
I am guessing this is to overcome DXVA or VAAPI shortcoming. What about AMD? We 
also have them.
