  • Writing subtitles on a video on different time frames

    22 mars 2023, par sarveshsta

    I am trying to write subtitles on a video. The problem is , with cv2(opencv-python), I am unable to write text on different time frames , lets say for first two seconds I want "Hello", and for another 3 seconds the video will show "this is the introduction" and so on.

    


    My question is, how can I achieve this with opencv-python. The thing why I want to use cv2 only is it creates an object for that video and do not create a new file, and that is important for my project.

    


    If you guys have any idea how we can write subtitles on a video without creating another file, please do let me know.

    


    I also tried ffmpeg it worked absolutely fine for me and I used a .srt file for that, but again it was creating a new file and same happened with moviepy library so in any case if you could show me a way how can we overwrite the file in ffmpeg or moviepy, it would be very helpful.

    


    THANKS.

    


  • Subtitles added to MKV with ffmpeg doesn't show

    15 avril 2023, par Efraín

    I've a weird problem, that I don't seem to understand what's happening. Basically, I've an MKV with 2 subtitle tracks, and I want to add a new one, so after searching a little, I worked this command

    


    ffmpeg -i "file v.mkv" -i "file s.ass" -c copy -map 0 -map 1 -metadata:s:s:2 language=eng -metadata:s:s:2 handler_name=English -metadata:s:s:2 title=English-dl output.mkv


    


    But when I opened output.mkv, and selected the 3rd sub track, It doesn't show the subtitles. I used MKVExtract to extract the track, and it correctly is the same .ass file that I merged, so I don't know why they don't show.

    


    I used this other command as example to make the previous one

    


    ffmpeg -i "file v.mkv" -i "file s.ass" -c copy -map 0 -dn -map "-0:s" -map "-0:d" -map "1:0" "-metadata:s:s:0" "language=eng" "-metadata:s:s:0" "handler_name=English"  "-metadata:s:s:0" "title=English-dl" "output.mkv"


    


    And this one correctly show the subtitles, but it erase the 2 original tracks of the MKV(Which I don't want to happen). What is the difference here that makes the second one show the subtitles, but the first one don't ? Do I have to lose the original subs for this ?

    


  • I want to get subtitles of images with CLI

    30 avril 2018, par user3387068

    I have movie data that BD has riped, with subtitles inside.
    Just that subtitle is saved as an image.
    So I’d like to get that subtitle image with CLI.
    Is there a good tool ?

    I will also post movie information from ffmpeg.

    Stream #0:0: Audio: flac, 48000 Hz, stereo, s32 (24 bit) (default)
    
Stream #0:1: Subtitle: hdmv_pgs_subtitle (default)
    
Stream #0:2: Subtitle: hdmv_pgs_subtitle
