  • Trouble trimming video by frame number with ffmpeg

    8 décembre 2023, par jgore200377

    I want to trim/split a video with ffmpeg using frames. The reason why is because I am using a Shot Transition Detection model which returns a probability of transition for every frame in the video.

    


    Using timestamps to cut the video has yielded bad results as the precision is not 100%.

    


    Ive tried this command which just outputs the entire video which is DEFINITELY not what I want

    


    ffmpeg -i video.mp4 -vf "trim=start_frame=100:end_frame=200,setpts=PTS-STARTPTS" -c:a copy output.mp4


    


    Ive also tried using python bindings with ffmpeg-python

    


    import ffmpeg

input_file = ffmpeg.input('video.mp4')
output_file = ffmpeg.output(input_file.trim(start_frame=1300, end_frame=1500), 'test_output.mp4')
ffmpeg.run(output_file)


    


    This doesnt work either and outputs a video with half of it being still with unpredictable length

    


    


    Ive visited some other sites but none seem to have this nailed down and it would be much appreciated if someone can answer how to use frames to trim/split a video with ffmpeg.

    


  • How to use input parameters in filter_() in ffmpeg-python ?

    17 avril 2018, par Linkyu

    I am using the ffmpeg-python wrapper.

    I want to use the crop filter to extract a cropped section of the video file ; I want the section’s size to be half the dimensions of the input.

    According to ffmpeg’s documentation, I can use the input parameters in_w and in_h like so :

    crop=1/2*in_w:1/2*in_h
    (or
    crop=w=1/2*in_w:h=1/2*in_h with named parameters)

    However, I struggle to find how to use them in ffmpeg-python. I figured I could pass them as standard arguments like so :
    filter_('crop', '1/2*in_w:1/2*in_h')
    but I seem to misunderstand how direct arguments work here because this does not work.

    Obviously, I can’t use keyword arguments either like so :

    filter_('crop', w=1/2*in_w, h=1/2*in_h)

    because they’re interpreted as undefined names.

  • aarch64 : vp9mc : Simplify the extmla macro parameters

    aarch64 : vp9mc : Simplify the extmla macro parameters

    Fold the field lengths into the macro.
    

    This makes the macro invocations much more readable, when the
    
lines are shorter.
    

    This also makes it easier to use only half the registers within
    
the macro.
