Either upload to incoming - see http://ffmpeg.org/download.html 
there is no size limit - or to any upload site like

No, please read what I have written (this would have been 
much easier if you had avoided top-posting):

I will use your (or a very similar) configure command to 
build FFmpeg and try to reproduce a decoding speed 
regression with the sample you upload on an Android 

Please note that I will (most likely) not test encoding 
with libx264, so if the reason for the regression are 
different versions of x264 that you use, you will have to 
ask on their mailing list (or use the same version).
