Thank you for the clarification. We’ve received the sample file and have already started working on resolving the issue.

Meanwhile, we would greatly appreciate your assistance in helping us cover all bases. Since you’ve mentioned encountering this issue with every video you’ve tested, could you kindly provide more details on the following:

  1. How have you set up CCExtractor?
  2. What specific errors are appearing in the other files?
  3. Could you share the specifications of the other files you are referring to?

Your input will be incredibly helpful as we work to resolve the issue effectively.
Thank you,
Tank0nf.

  1. Standard Linux compilation through Autoconf scripts
  2. Same error for all video files: No captions were found in input. Empty srt files are created
  3. tested with my jellyfin library: all mkv files with embedded srt subs

Maybe the sample I provided wasn't the best because I created it using this command:
ffmpeg -i movie.mkv -ss 00:00:00 -t 15 -c copy sample_video.mkv
but not captions are shown in the first 15 secs

Okay. That's weird. I created another sample, now in the middle of the movie and tested with ccextractor and it worked:

I can't understand how can it work with this 10 sec sample and not with the original video file. Maybe some metadata issue corrected by ffmpeg?

I created another sample, now in the middle of the movie and tested with ccextractor and it worked: ``` Opening file: sample_video.mkv File seems to be a Matroska/WebM container Analyzing data in Matroska mode Document type: matroska Timecode scale: 1000000 Muxing app: Lavf61.7.100 Writing app: Lavf61.7.100 Track entry: Track number: 1 UID: 6468560451154994440 Language: und Codec ID: V_MPEG4/ISO/AVC Type: video Track entry: Track number: 2 UID: 5573667526452854584 Language: per Codec ID: A_AAC Type: audio Track entry: Track number: 3 UID: 7313999796934396663 Language: eng Codec ID: S_TEXT/UTF8 Type: subtitle 0% | 00:00 Found large gap(73) in PTS!

Hey @jaum20 the issue has been fixed please try to update your CCExtractor and running as many MKV files you want :)

The main reason the small sample of video was working and not the whole MKV file was because their were some sections of the video presumably later on where their were issues with the IETF tags present, your contributions has helped us very much in improving CCExtractor and we would be glad to assist to solve any further issues that you might face, we greatly value your opinion and constructive criticism to help CCExtractor grow.
Thank you,
Tank0nf.
