[FFmpeg-user] Does FFmpeg support AVC-Intra (and/or x264) with 10bit bitdepth? (yuv422p10le)

> Most likely your x264 was build using option --bit-depth=8. Have a look here http://video.stackexchange.com/questions/13164/encoding-422-in-10-bit-with-libx264 <http://video.stackexchange.com/questions/13164/encoding-422-in-10-bit-with-libx264>

hm why must be x264 compiled with 8 or 10bit and not both?
With other codecs this works without problems: ffvhuff, ffv1, DNxHD.
Why is x264 so special in the bitdepth/pixelformat? Can anyone explain 
this to me please?
Maybe is it possible to compile ffmpeg with 2 different libx264 codecs? 
one for 10 and one for 8bit?

like:
vcodec = libx264
vcodec = libx264_10
