Hi I am new to ccextractor, but I'd like to understand it better. I'd like to help solve this issue, is it up for grabs? How can I go about it? I am working on an OSX machine.

@MatejMecka commented on GitHub (Oct 29, 2018):

I Commented out the line causing the error and the output is terrible.

The subtitle begins 10 seconds later and i miss a lot of subtitled commentary. Even with the 10 second delay the subtitles are never matched with the Commentators.

Also for some reason the last line in the subtitle block is repeated on the next beginning block.

You can also notice that the last part is cutout.

I've attached the .srt file below and I'll continue debugging to find the cause.

UPDATE: Apparently they are roll-up captions and i'm an idiot. And apparently this makes the subtitles in CEA-608(I might be saying dumb stuff, forgive me for my mistakes).

UPDATE 2: This happens in the First Track which is an AVC Track. Caption Blocks are being extracted all the time in user_data_registered_itu_t_t35 avc_functions.c Including where the error arrises too.

b8c1499111/src/lib_ccx/avc_functions.c (L503)

During Monitoring the local_cc_count variable I noticed that all the time it's 20 and then becomes 0 and exits. This Occurs Multiple times during the stream! cc_tmp_data[local_cc_count*3] is always 255 '\xff' and is affected by the local_cc_count when it goes to 0
