  • How can I use ffmpeg to crop a part of a video by frames numbers including video and audio ?

    28 mars 2019, par Dubi Duboni

    I have a simple list :

    LReg.start = rise[i];
    
LReg.end = fall[i];
    
LR.Add(LReg);

    start and end are int’s in the end I have a List of the frames I want to extract from a video file. For example in index 0 of LR I have start 48 end 51
    In index 1 start 110 end 124

    So I want to loop over the List an save as a video file the part of a video file using ffmpeg according to the frame number start and end by jumping to this frames.
    Jump to frame 48 and create a video file out from frame 48 to 51 including 48 and 51. Then jump forward to the next group of frames 110 and 124 and so on.

    The problem is how to use ffmpeg to extract and save video files ?

  • FLutter : Read frames fom video, process it, put it to output video

    26 juin 2023, par RAITON

    I have video record and I need to process frames of this video, and for each frame/image write random integer on top left or right of image ( the random integer is only example I will replace this random int by my logic )

    


    something like :

    


    // 1. extract list of frames from video
// 2. process images/frames and add random integer in top left or right of image
// 3. Write output Video with new Frames contain the random integer 


    


    can someone help to have code example to resolve this by using ffmpeg package or any other package ?

    


    Thanks

    


  • trimming video using ffmpeg corrupts output video stream

    6 décembre 2022, par I Z

    I am using ffmpeg to cut up a long video into sections. Using this command :

    


    ffmpeg -i "long.mp4" -ss 00:38:25 -to 01:01:11 -c copy "section.mp4" 


    


    I extracted a couple of different consecutive sections and they are fine. But then I cut out another one and its video stream is bad : just a few static frames are shown. Removing -c copy did not help. What am I doing wrong ? TIA
