• FFmpeg videos not working on QuickPlayer (and therefore on OpenCV)

  7 mai 2018, par Gabrielle

  I know that there are several posts about FFMpeg not working on QuickPlayer (and OpenCV) and other players supporting only YUV planar color space, but NONE of the solutions I’ve found worked for me.

  I need it to run on OpenCV, but as far as I found, it will never run on OpenCV if it is not running on QuickPlayer, so, I think I might start fixing the QuickPlayer issue. The generated video is a screen record, and it works perfectly on VLC.

  Configurations used :

  MacOs High Sierra
  
  ffmpeg version 4.0 (installed with: --with-opus --with-libvpx )
  
  opencv version 3.4.1_4
  
  Homebrew 1.6.2 (used to install ffmpeg and opencv)

  Command used to record the video :

  ffmpeg -f avfoundation -video_size 1980x1140 -framerate 30 -i '1' 
  
  -vcodec libx264 -preset ultrafast -an -qp 0 -pix_fmt yuv444p video.mkv -y

  Note1 : I already tried to change -pix_fmt to yuv420p

  Note2 : I already tried to add -vf scale=640:-2,format=yuv420p

  Note3 : I already tried to re-install OpenCV --with-ffmpeg

  Note4 : I tried mkv, mp4, avi. I really don’t care about the extension, I just need it to work.

  Note5 : I need it to be a cross-plataform solution, as far as I read ffmpeg should work in all OS, but first I am trying to fix on mac and then I will check others...

  Any ideas ? Maybe a missing flag ? A missing library ?

  @Gyan suggested me to change the qp flag to a number higher than 0, I did it

  ffmpeg -f avfoundation -video_size 1980x1140 -framerate 30 -i '1' -vcodec libx264 -preset ultrafast -an -qp 2 -pix_fmt yuv444p video_test.mp4 -y

• FFMpeg Watermark Quality Very Bad

  22 janvier 2016, par John Cliven

  I’m trying to add a watermark to a video which works fine, the only issue is the quality is greatly degraded. It also reduces the resolution of the video, making it a smaller size than it originally was. I am using the following command :

  ffmpeg -i fade.mp4 -i watermark.png -filter_complex "scale=512:-2,overlay=(main_w-overlay_w)-2:(main_h-overlay_h)-2" -strict -2 final.mp4

  I have also tried the following to specify high quality, but it produces the same bad quality video :

  ffmpeg -i fade.mp4 -i watermark.png -filter_complex "scale=512:-2,overlay=(main_w-overlay_w)-2:(main_h-overlay_h)-2" -qscale 0 -strict -2 final.mp4

  Here is the output from ffmpeg :

  root@shell:~/videos# ffmpeg -i fade.mp4 -i watermark.png -filter_complex "scale=512:-2,overlay=(main_w-overlay_w)-2:(main_h-overlay_h)-2" -strict -2 final.mp4

• ffmpeg.wasm - How to do literally anything with a blob url

  24 novembre 2024, par SeriousLee

  I'm using the ffmpeg.wasm for the first time and I can't get anything working, beyond loading it. I have this function that does nothing in particular (I got it from the vite + react example in the docs, slightly modified) and all I want to do is pass it a blob URL like this blob:http://localhost:5173/c7a9ea7c-aa26-4f4f-9c80-11b8aef3e81f and run through the function and have it give me anything back. But instead, it hangs on the ffmpeg.exec command and never completes. And yes, I've determined that the input blob does work - it's an 8MB, 12-second long mp4 clip.

  


  Here's the function :

  


      const processOutputVideo = async (videoURL) => {
      const ffmpeg = ffmpegRef.current;

      await ffmpeg.writeFile("input.mp4", await fetchFile(videoURL));
      await ffmpeg.exec(["-i", "input.mp4", "output.mp4"]);

      const fileData = await ffmpeg.readFile("output.mp4");
      const blob = new Blob([fileData.buffer], { type: "video/mp4" });
      const blobUrl = URL.createObjectURL(blob);

      return blobUrl;
    };


  


  And here's the ffmpeg logs from my terminal.
