  • I have a series of images recorded by a webcam with unstable frame rate at about 22 fps. Did ffmpeg interpolate these image into other fps ? [closed]

    13 septembre 2020, par yangze68

    I have a series of images and its recorded timestamps. Their real fps is about 22 and it's unstable. If I use the FFmpeg to encode it into a 30fps video, do these really change the fps and interpolate image at an interval of 1/30 per second ? or Just arrange those images in the interval of 1/30 and decrease the total duration time ?

    


    my command :
ffmpeg -framerate 30 -i img%03d.png output.mp4

    


  • Get total duration of multiple video files ? [duplicate]

    16 novembre 2018, par Soyal7

    This question already has an answer here :

    I want to extract video duration metadata from every video file in a specified directory and then sum all and view the total time in desktop app.

    I need to extract data from as much as hundreds of videos overall. In Windows I can view the total duration for many files manually when selecting them in the explorer and going into details. For 1500 mp4 files it takes about 20 seconds to make the calculations and view the total time. It’s much faster then what I’m currently getting when iterating with FFprobe.

    for filename in dirFiles:
    
   print(subprocess.check_output(['ffprobe', '-i', filename, '-show_entries','format=duration', '-sexagesimal' ,'-v', 'quiet', '-of', 'csv=%s' % ("p=0")]))

    What is the faster way to do this ?

  • avformat/http: Add option to limit total reconnect delay

    22 avril 2024, par Derek Buitenhuis
    avformat/http: Add option to limit total reconnect delay

    The existing option only allows users to set the max delay for a
    
single attempt, rather than the total allowed delay, which is both
    
pretty unintitive, and only applicable when exponential backoff is
    
used.
    

    The default for this option is set to 256, which is just above the
    
effective total delay accomplished by the the existing
    
reconnect_delay_max default of 120.
