  • Make blurred background faster with ffmpeg

    26 septembre 2022, par Peter Czask

    I have a vertical videos which I'll like to make them horizontal 1920x1080 with blurred background.

    


    I do it with this command :

    


    ffmpeg -i input.mp4 -vf 'split[original][copy];[copy]scale=ih*16/9:-1,crop=h=iw*9/16,gblur=sigma=20[blurred];[blurred][original]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2'  output.mp4 


    


    which that code I'm satisfied with the result, except that it takes very very long time to produce it. Is there any way to speed it up ? I noticed that the blurred part on the background uses half of the overlay video (non blurred), I'll like to blurry just with the edge (or 10 pixels) of the non blurred video (if this makes the encoding faster)...

    


  • avformat_write_header() changes my stream's time_base

    12 avril 2023, par greken

    I have a high framerate camera which can capture >2000 fps. My plan was to assign actual capture timestamps with µs resolution to the frames and encode with H.264 in a matroska file.

    


    So I set the time_base of both the AVStream and the AVCodecContext to {1, 1'000'000}. But after calling avformat_write_header(avFormatContext, nullptr) I notice that the stream's time_base is {1, 1'000}. Now, since my framerate is double this resolution, I get identical consecutive timestamps and half my frames get lost when I extract them from the video file.

    


    Does anyone have an idea why this is happening and what I can do about it ? Preferably in a way that preserves the correct timestamps.
