  • Split video with ffmpeg segment option is missing frame

    9 février 2024, par Dan

    I’m trying to get the ffmpeg “segment” option to split my video into segments at the Iframes. I'm using ffmpeg V6.1.1.

    


    First I added time stamps to each frame of my video so that when it plays, I can see exactly which frame is being displayed. I used this command :

    


    ffmpeg -i In.mp4 -vf "drawtext=fontfile='C :\Windows\Fonts\Arial.ttf' : text='%frame_num :~ %pts':fontsize=200 : r=25 : x=(w-tw)/2 : y=h-(2*lh) : fontcolor=white : box=1 : boxcolor=0x00000099" -y Out.mp4

    


    Then I used ffprobe to confirm that the video is 30 FPS and the Iframes are as follows :

    


    0.000000
4.933333
10.000000
11.533333
18.866667
24.966667

    


    Based on these Iframe times, I’d expect the following segments :

    


    





    


    


    


    


    


    


    



    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    


    Start Frame Start Time End Frame End Time
    0 0 147 4.900000
    148 4.933333 299 9.966667
    300 10.000000 345 11.500000
    346 11.533333 565 18.833334
    566 18.866667 748 24.933334
    749 24.966667 867 28.906667

    


    


    When I use ffmpeg to split the video into segments with the following command, I get six files as expected :

    


    ffmpeg -i Out.mp4 -f segment -c copy -reset_timestamps 1 -map 0 "Out %d.mp4"

    


    When I play the segments, they are all correct except the first segment file (Out 0.mp4). It seems to be missing the last frame. It contains frames 0 to 146 (4.866667 sec) but should also include frame 147 (4.9 sec). All the other segment files are as expected.

    


    I’ve tried this on several different mp4 videos and they all are missing the last frame on the first segments.

    


    Any idea why my first segment files is missing the last frame of the segment ?

    


    Could this be an ffmpeg bug ?

    


    Thanks for the help !
Dan

  • FFmpeg : Audio is sped up after compressing AVI video [closed]

    21 août 2023, par Karen S

    I have an AVI video and I want to reduce the file size. When I run the FFmpeg command below, the resulting audio in the video is sped up, and the last bit of the video has no audio.

    


    The FFmpeg command

    


    ffmpeg -i "in.avi" -vcodec libx264 -acodec copy -crf 26 -vf "scale=-1:'min(720,ih)', yadif=1" out.avi

    Since the audio stream is being copied I don't understand why the resulting audio sounds sped up. The video looks fine, it's just the audio that is the issue.

    


    I've tried other options too, such as converting the audio to aac or mp3 and the resulting audio still sounds sped up and high pitched.

    


    Does anyone know why the audio isn't simply being copied the way it sounds in the original AVI video and do you have any suggestions for how to fix the issue ?

    


  • FFmpeg : Audio is sped up after compressing AVI video [closed]

    21 août 2023, par Karen S

    I have an AVI video and I want to reduce the file size. When I run the FFmpeg command below, the resulting audio in the video is sped up, and the last bit of the video has no audio.

    


    The FFmpeg command

    


    ffmpeg -i "in.avi" -vcodec libx264 -acodec copy -crf 26 -vf "scale=-1:'min(720,ih)', yadif=1" out.avi


    


    The output messages
