  • How can select only two audio streams in a video and feed it to the ebur128 filter wiithin ffmpeg ?

    18 avril 2017, par Edwin

    I want to use FFmpeg to analyze the loudness of an MXF video file.
    I have an MXF file with 8 mono audio streams. I only want to feed the first two streams through the ebur128 filter. But I can’t find a way to do that. The FFmpeg documentation is not clear to me, as I am fairly new to FFmpeg.

    I tried several things :

    ffmpeg -i source.mxf -nostats -filter_complex ebur128=dualmono=true:panlaw=-3.01dB -f null -

    I am sure it’s just that I don’t have the filtering syntax right. But hey... I’m a newbie...

    ffmpeg -i myVideo.mxf -nostats -filter_complex [0:a:0][0:a:1]amerge; ebur128=dualmono=true:panlaw=-3.01 -f null -

    And this is the resulting console output :

  • How to convert large sequence of static gifs to video ?

    29 mars 2018, par Quinn

    I am trying to convert a large amount of static gifs(not animated) into video, but am completely lost on how to proceed.

    Specifications :

    QTY : 7,500 - 10,000 static .gif images

    File Size : 11kb ea.

    Image Dimensions : 580x580px

    File Naming : I_20000880002-20000880626.gif, I_20000880626-20000882042.gif, I_20000882042-20000891054.gif, etc...

    I have tried many different things, but none of them have worked. First, I tried Adobe Media Encoder. That failed, it couldn’t handle 10k files. I tried ffmpeg, which didn’t really work. The code I used is as follows :

    ffmpeg -r 60 -f image2 -s 580x580 -i pic%04d.png -vcodec libx264 -crf 25  -pix_fmt yuv420p test.mp4

    This didn’t work because it was trying to import .png files. I then changed the .png extension to .gif in the code. So :

    ffmpeg -r 60 -f image2 -s 580x580 -i pic%04d.gif -vcodec libx264 -crf 25  -pix_fmt yuv420p test.mp4

    I’m not an expert in ffmpeg by any means, so the code I executed might not have the proper syntax, at least in regards to -i pic%04d.gif. I suppose I could convert the .gifs into .pngs, then run the original code, but I’m not totally sure how to do that with ffmpeg.

    If anyone has any tips, they would be most appreciated. Also, I am using Windows 10 but I do have the linux subsystem installed. Thanks.
