x265 Encoding Issue with MP4Box

[Selur]

MP4 box crashed when the Signal PAR 1:1 was flagged

(strange thing is that the log doesn't contain any crash)
-> Can you please create another debug output (level 9) of the job processing?

Ps.: I attached more recent builds of x265 and MP4Box for you, please check whether these fix the issue for you.
