  • (FFmpeg) VP9 Vaapi encoding to a .mp4 or .webm container from given official ffmpeg example

    13 mai 2021, par User800222

    I'm trying to implement vp9 hardware acceleration encoding process. I followed ffmpeg offical github's example (Here -> vaapi_encode.c).

    



    But given example only save a .yuv file to .h264 file, I would like to save the frames to either .mp4 or .webm container. And having the ability to control the quality, and etc.

    



    I'm not reading frames from a file, I'm collecting frames from a live feed. When having full 5 secs of frames from the live feed, encode those frames using vp9_vaapi to a 5 secs .mp4 file.

    



    I'm able to save all the 5 secs frames from my live feed to a .mp4 or .webm file, but they couldn't be played correctly (more precisely : keep loading, and I open).

    



    The result from the official site's example :

    



    enter image description here

    



    The cpu encoded vp9 .mp4 file result :

  • Mask dynamic logo using ffmpeg

    27 mars 2018, par Francesco De Pazzi

    I am trying to detect and hide a logo that dynamically positioned in a video.

    In this video the logo is positioned at the top and after a few minutes down etc.

    it’s possible to detect every time the logo when it changes place and hide it with ffmpeg ?

    I tried with delogo but I must tell the position x/y, so it is not possible in my case !

    Thank you very much !
