  • How to create a circular countdown indicator overlayed into a video with ffmpeg ?

    18 novembre 2020, par Ben Holness

    I have a script that creates a video from multiple sources. At the start of the video there is a 5 second long pause where some information is displayed.

    


    I want to give a visual indicator of how long it is until the main video starts, with a circle in the top left corner. The circle would start completely transparent and slowly fill in grey round the circle as the video progresses. At 25% of the video, the top right quarter of the circle would be gray. At 50% the right half of the circle would be gray and so on.

    


    I am imagining something similar to this solution which is a progress bar, but I'm not sure if it's possible/how to make it a circular one.

    


  • Invalid radius value in BlurMask Ffmpeg

    15 avril 2022, par Vivek Thummar

    I'm using boxblur filter to blur specific area of video using cropping library, when i fire command sometimes it works well but sometimes it's showing me error.
Command and error are as below :

    


    ffmpeg -ss 00:00 -t 02:43 -i input.mp4 
-filter_complex crop=28:24:20:14,boxblur=25[fg];[0:v][fg]overlay=20:14,
-vcodec libx264 output.mp4


    


    This is throwing error - Invalid luma_param radius value 25, must be >= 0 and <= 12

    


    In this command crop=... can be vary according to user need and boxblur=25 is static.
So, if the error is related to boxblur then the question is why sometimes it works or if this was not the problem then what is the problem and solution ?

    


  • ffmpeg -acodec and -vcodec paramter inputs list

    5 mai 2014, par Sajith Dilshan Jamal

    Is there a list somewhere for ffmpeg which lists what the libraries we enter into the -acodec/ -vcodec parameters support ?

    eg : ffmpeg -vcodec x264 -acodec libmp3lame

    I would like a list showing which formats x264/libmp3lame support.

    Also is there a list that shows all possible inputs to the -vcodec & -acodec parameters.
