mkvmerge: The JSON output generated by mkvmerge cound not be parsed (parser's error message)

Hello. Guten Tag.

If xxx.ts file(mpeg2 transport stream file) is opened, parser's error is displayed.

The error message itself is same as Issue #2327 (closed). (I have reported #2327 (closed) before).

I have uploaded "up2018-10-06[Chaos].zip" file via SFTP.

The zip file includes sample mpeg2-TS file(.ts) and screen shot file.

Could you check the files?

[Steps]

Open MKVToolNix GUI v27.0.0, 64bit.

Choose "Add source files" in multiplexer tab.

Choose the uploaded xxxx.ts file.

The following error message is displayed.

Please refer to the "20181006-ScreenShot.png" in uploaded zip file.
