    I have 2 video which i want to add them together so i make a text file which contains the file names

    file No-fade_25fps.mp4
    file video.mp4

    then i start using this command

    ffmpeg -f concat -i ffmpeg-sound.txt -c copy final_output.mp4

    the problem is i got this from ffmpeg

    [mov,mp4,m4a,3gp,3g2,mj2 @ 05c3e940] Auto-inserting h264_mp4toannexb bitstream filter

    video:2157kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 4.486598%

    the result give me a video mp4 file with a long duration like 46:33:20 and it not work, and iam sure that both videos have same reslution.
    what i tried is to use this command to convert the video

    ffmpeg -y -i No-fade_25fps.mp4 -r 25 -s 1280x720 -c:v libx264 -b:v 3M -strict -2 -movflags faststart destination.mp4

    and when i concate them again it worked and give me result mp4 file which have a right duration and worked fine but without a sound, because the first video file i use is muted no sound in it and second one contains a sound.
    my question is how to concate those videos togther without this problem also what make the video have the problem of this long duration and when i convert them using the command line it worked ?
    first video info which is No-fade_25fps.mp4

  • FFMPEG Video Cropping slower [duplicate]

    23 juin 2016, par syed imty

    This question already has an answer here :

    I am trying to crop rectangular video into a square one using FFMPEG. The video conversion take too much time.

    For a video of 30 secs, it takes around 60-70secs to convert

    FFMPEG Command

    String commandStr =" -i "+videoPath+"  -vcodec libx264 -b:v 880k -vf crop=" + videoSize.height + ":"+ videoSize.height + ":" + cropStart +":0 -preset ultrafast -strict -2 " +compressedVideoPath;

    Need help to make it faster.

  • orangepi zero 2w, ubuntu, using a usb webcam ffmpeg to record videos, low FPS [closed]

    28 janvier, par Qingfu Shi

    I use a OrpangePi zero 2w, USB HIK 2K Cam, to record videos.
Ubuntu, ffmpeg installed,
the cmd

    


    ffmpeg -f v4l2 -video_size 1920x1080 -r 25 -input_format mjpeg -i /dev/video1 -vf "transpose=1" -c:v libx264 -preset fast -crf 23 output.mp4


    


    I want the fps to be at least 25, so it looks smooth, but I only got about 4.7 fps.
