Are there any parameters that MUST be supplied with FFmpeg-native
arguments, or is it possible to send ALL x264 parameters through
x264opts? Example:

X264_OPTS=<args here>
ffmpeg -i in.mov -an -vcodec libx264 -x264opts $X264_OPTS -y out.mp4

For what it's worth, I would prefer this over having a combination of
FFmpeg args/x264opts.
