  • ffmpeg video overlay between not responding to timestamp

    21 novembre 2022, par PiotrK

    Just cant get ffmpeg to overlay png at the desinged time. I tried all the options and its always displaying in wrong times.

    


    import subprocess

subprocess.call([
    'ffmpeg',
    '-y',
    '-i', 'out_1.mp4',
    '-i', 'overlay.png',
    '-filter_complex', "[0:v][1:v]overlay=0:0:enable='between(t,0,0)",
    '-codec:a','copy',
    'out_2.mp4'
])


    


    When I change between(t,0,0) its display in second from 0 to 10. I need this to display in second from 0 to 1 of the video. The video total duration is 50 seconds.
Here is the screen recording to show my problem

  • ffmpeg encoding with VP8 producing bad looking video

    25 décembre 2017, par Radu

    I am working at a time lapse program that invokes ffmpeg via system() to encode a video from a sequence of JPGs. The user can chose a few options, including the compression codec.
    I am getting very good results when using libx264 and the mjpeg encoder. I am getting so and so results with VP9, and I am getting some horrible results with VP8.

    I am invoking ffmpeg like so : ffmpeg.exe -framerate 12 -i "./output/img_%05d.jpg" -dst_range 1 -color_range 2 -c:v libvpx -b:v 0 -threads 8 -speed 2 -crf 8 "./output/video.webm"

    I uploaded a sample to youtube : https://www.youtube.com/watch?v=eG2jxzR3Uxs (you can see the really bad frames after the 9 seconds mark.

    Any idea what I am doing wrong ?
