The following video file was was recorded in mainland China, using Joker-tv with the DTMB television standard. When I watch it, I'm seeing what looks like subtitles / captions. Can CCExtractor see them? I was not able to get it to work. I did not try OCR, which may be what is required.

@Liontooth @cfsmp3

The subtitles in the given video file can be extracted using hardsubx parameter.

./ccextractor 2018-01-09_2033_CN_CCTV1_新闻1+1.mpg -hardsubx -ocrlang chi_sim

To display them in the video player one requires compatible fonts but they are indeed being extracted and below is an image showing the same.

There are errors in the output due to inaccuracies of the OCR but they are out of the scope of this issue and is a separate GSoC project.

Assigned to @Abhinav95 which in turn will assign it to the GSoC student(s) he sees fit.
