This is kind of 2 requests in one.
For one, it would be awesome if the tmod x264 version was selectable, as it has some extra parameters that I like to use to improve my encodes. This is the one I mean: https://github.com/jpsdr/x264/releases
Second, I love encoding at 10 bit for a bit more efficiency and better dark values for potential screenshots/regrades. I know there's no hardware acceleration, but could this be made possible somehow either way? A 10 bit version is included with the tmod version.
I believe the relevant branch for the code is t_mod_New
I have no idea how much work this would be, so I'm just throwing it out there for your consideration. At least a 10 bit variant would be very nice, even if its not tmod.
