    avcodec/webp : add assert to ensure palette is not larger than 256

    it should not be possible to be larger as its stored as 8bit value
    
but we would be overwriting a stack buffer if it is ...

  • ffmpeg : thumbnail of frame, preserve aspect ratio, apply background / padding / fill colour

    16 octobre 2014, par Pistos

    I already have found out how to scale the thumbnail to stay within specified bounding dimensions while maintaining aspect ratio. For example, to get the frame shown at 6 seconds into the input.mp4 video file, and scale it to fit into 96x60 (16:10 aspect ratio) :

    ffmpeg -y -i input.mp4 -ss 6 -vframes 1 -vf scale="'if(gt(a,16/10),96,-1)':'if(gt(a,16/10),-1,60)'" output.png

    This is fine, it works.

    Next, I would like to do the same, but if the video’s aspect ratio is not exactly 16:10, then I would like to force the output image to have an aspect ratio of 16:10 by taking the above transformation, and filling or padding the space with white. That is, I want the output to be as if I took, say, a 96x48 image, and laid it over a 96x60 white background, resulting in white bars above and below the 96x48 image.

    Ideally, I do not want to resort to using another tool or library, such as ImageMagick. It would be best if ffmpeg could do this on its own.
