  • Can I create a circular countdown indicator overlayed into a video with ffmpeg ?

    9 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.

    


    Thanks !

    


  • libavcodec/exr : simplify reorder_pixels

    libavcodec/exr : simplify reorder_pixels

    reorder_pixels is call by rle_uncompress and zip_uncompress
    
with size == uncompress_size
    

    uncompress_size is a multiple of 2 (because exr store data
    
in half, float, or uint32)

  • x264 rate control modes

    19 septembre 2013, par xkfz007

    Recently I am reading the x264 source codes. Mostly, I concern the RC part. And I am confused about the parameters —bitrate and —vbv-maxrate. When bitrate is set, the CBR mode is used in frame level. If you want to start the MB level RC, the parameters bitrate, vbv-maxrate and vbv-bufsize should be set. But I don't know the relationship between bitrate and vbv-maxrate. What is the criterion of the real encoding result when bitrate and vbv-maxrate are both set ?
    And what is the recommended value for bitrate ? Equals to vbv-maxrate ?
    Also what is the recommended value for vbv-bufsize ? Half of vbv-maxrate ?
    Please give me some advice.
