[BUG] Crash when using x265 ST2084 encoding at latest version (2017.10.3.1)

[Selur]

But I'm facing another problem: MP4Box muxing chock

I've got error message of: "The given code is not a valid one: , using 'und' as 3-letter code"

Seems like I have to give a language code to my audio, 'cause it's empty at the current command code

starting 06_35_25_3310_09_muxing@09:11:52.763 - T:\InnoLux-4K-HDR-HEVC.mp4

Just arrived in Beijing, will try to look a it later.
To be sure please check if it works if you use:

"C:\PROGRA~1\Hybrid\MP4Box.exe" -par 1=1:1 -add "T:\06_35_25_3310_06.265"#video:fps=60 -brand hvc1 -add "T:\iId_1_aid_1_06_35_25_3310_02.aac"#audio:lang="und" -mpeg4 -itags name="InnoLux-2017-4K-HDR-色彩的溫度":comment="www.HD.Club.tw":tool="Hybrid 2017.10.05.1" -tmp "T:\" -new "T:\06_35_25_3310__09.mp4"

or

"C:\PROGRA~1\Hybrid\MP4Box.exe" -par 1=1:1 -add "T:\06_35_25_3310_06.265"#video:fps=60 -brand hvc1 -add "T:\iId_1_aid_1_06_35_25_3310_02.aac"#audio:lang="und" -mpeg4 -itags name="InnoLux-2017-4K-HDR-test":comment="www.HD.Club.tw":tool="Hybrid 2017.10.05.1" -tmp "T:\" -new "T:\06_35_25_3310__09.mp4"

Does one of those two command lines work (or both?).
