[x265] using mp4 input files

[Michael Lackner]

ffmpeg is not the x265 command line. It's ffmpeg, using x265 as a library. When using x265
as a command line program directly, you would usually decode the input with ffmpeg, and
then pipe it to x265, likely as Y4M.

So, maybe like this:

$ ffmpeg -r 24 -i input.mp4 -f yuv4mpegpipe -pix_fmt yuv420p -r 24 - 2>/dev/null | x265 -
--y4m output.h265

When using only ffmpeg (linked against x265), the syntax would be something like this:

$ ffmpeg -i input.mp4 -c:v libx265 output.h265
