  • ffmpeg generate overlay complex filter for audio with background image

    8 January 2016, by user1793606

    I am experimenting with ffmpeg and would like to generate overlay complex filter for audio with background image. The code normally works, except for when adding -filter_complex "[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]" -map "[v]" -map 0:a
    it crashes. I found the example code at https://trac.ffmpeg.org/wiki/Waveform Any help is appreciated.

    Command '['c:/ffmpeg/bin\\ffmpeg.exe', '-y', '-loop', '1', '-r', '1', '-i', 'temp\\bg.png', '-i', 'test.mp3', '-filter_complex', '[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]', '-map', '[v]', '-map', '0:a', '-c:v', 'libx264', '-preset', 'ultrafast', '-tune', 'stillimage', '-crf', '15', '-pix_fmt', 'yuv420p', '-strict', 'experimental', '-c:a', 'aac', '-b:a', '256k', '-shortest', '-threads', '0', 'done/test.mp4']'

    EDIT 1:

    I tested this with the new verson: ffmpeg -y -i input.mp3 -i background.png -filter_complex "[0:a]showwaves=s=1280x720:mode=line,format=yuv420p[v]" -map "[v]" -map 0:a -c:v libx264 -c:a copy output.mp4

    It generates an output file, but only the waveform, no background included. My end goal is to generate the waveform over the background.

  • PySceneDetect FFmpeg Not Available

    14 August 2023, by Dmitriy Pushkarev

    I already installed FFmpeg and this is available in terminal I can convert video and etc, but it's completely not available in PySceneDetect.

    


    pip installed FFmpeg-python and FFmpeg library and FFmpeg itself in system.

    


    PySceneDetect returns:

    


    ffmpeg could not be found on the system. Please install ffmpeg to enable video output support.


    


    I think trouble with path, but can't put path in PySceneDetect. I can use path to binary FFmpeg, only in ffmpeg-python library, like this and it's working

    


    This code working fine:

    


    Here i using only FFmpeg-python library

    


    stream = ffmpeg.input('vi0.mp4')
stream = ffmpeg.filter(stream, 'fps', fps=10, round='up')
stream = ffmpeg.output(stream, 'vi1.mp4')
ffmpeg.run(stream,cmd='./ffmpeg')


    


    But can't it to get work with PySceneDetect

    


    print(scenedetect.video_splitter.is_ffmpeg_available())


    


    return False

    


    split_video_ffmpeg(video_path, scene_list, show_progress=False)


    


    returns "ffmpeg could not be found on the system. Please install ffmpeg to enable video output support."

    


  • qt-faststart: Fix the signedness of variables keeping the ftello return values

    qt-faststart: Fix the signedness of variables keeping the ftello return values

    These variables are assigned the return values of ftello, which
    
returns an off_t, which is a signed type. On errors, ftello returns

    - 1, thus make sure this error return value can be stored properly.
