This will encode using libx265 which is beyond our control (and has
issues with Valgrind). This would only work if the codec were lossless;
but your command line isn't.

Anyway, you should instead just use any of our hevc samples and remux it
to flv and read the resulting file. There are lots of examples of how to
do this that also avoid keeping the intermediate file around.

The other two patches have the same issues.
