    lavc/movtextenc : add option to scale fontsize with height

    If the video dimensions are different than the ASS play_res then the
    
font sizes need to be adjusted to get the same apparent render size.

  • How can ffmpeg scale videos to the same size, preserving their aspect ratio ?

    4 avril 2020, par GreenTriangle

    (I have searched similar questions and haven't found anything that works the way I describe here.)

    &#xA;&#xA;

    I have a number of videos of varying sample and display aspect ratios(and different framerates and timebases). I want to concatenate them into one long video, like a playlist, which means re-encoding them. I want them to scale up or down to fit within the desired output size (768x432), preserving their aspect ratio by pillarboxing when necessary.

    &#xA;&#xA;

    I've tried -vf scale=768:432:force_original_aspect_ratio=decrease,pad=768:432:(ow-iw)/2:(oh-ih)/2, which produces a 768x432 16:9 video from a 16:9 input... but squishes it vertically and adds pillarboxing anyway. (The input is 720x480 with a 32:27 sample aspect ratio. Input of a 10:11 SAR, 4:3 DAR 704x480 video works.)

    avcodec/lagarith : Sanity check scale

    A value of 24 and above can collaps the range to 0 which would not work.
