I am using
cmd: /usr/bin/ccextractor -nobom --service all[ISO88591] -nofc -ts -12 -s 180 /home/dn/ramesh/191505_20201123020000.ts

its generating caption like

-rw------- 1 root root 205930 Nov 23 11:23 191505_20201123020000_1.srt
-rw------- 1 root root 0 Nov 23 11:04 191505_20201123020000_2.srt
-rw------- 1 root root 132090 Nov 23 11:04 191505_20201123020000.p1.svc01.srt
-rw------- 1 root root 76040 Nov 23 11:04 191505_20201123020000.p1.svc03.srt

why 191505_20201123020000_2.srt is empty, its should generate 608-cc3 caption.

@pree-T @cfsmp3 I actually wanted to go for it as well by getting the file to reproduce the issue first of all, is it alright if I try to work on it as well ? Or should I leave it ?

You can work on it as well, but given that @Rameishkumar123 still didn't provide a video link it might be very hard to reproduce it.

Hi! I’ve understood the issue.

Summary of the problem:

When extracting captions, an empty file is generated for CC3 (608 channel 3), even if there are no captions present on that channel.

Plan to solve:

I’d like to first confirm whether the input file actually contains any CC3 captions.
    Could you please provide a sample file (or a link to it) so I can check if CC3 is really empty?
If I confirm that CC3 is empty, I will update the code to prevent generating an output file for channels with no captions.
    The idea is: only create/write the file if there are actually captions found for that channel.

Implementation (planned):

Before generating/saving the subtitle file, add a check like:

if (captions_found_on_channel) {
    save_caption_file_for_channel();
}

This would ensure that empty files are not created for channels with no captions.

Let me know if you can share a sample file, or if you have any additional requirements. I’ll start working on this!
