  • How to change macroblock's size in H.264 ?

    12 juin 2021, par Euphoria Yang

    I am using ffmpeg api to implement this paper(Passthrough+ : Real-time Stereoscopic View Synthesis for Mobile Mixed Reality). In this paper, they use 8x8 macroblock to calculate motion vectors. However, most of macroblocks are encoded in 16x16 pixels by ffmpeg. How to force macroblock size to be 8x8 using ffmpeg api(or can be done by modifying libavcodec/libx264.c) ?

  • Choose correct font size for video output

    29 août 2020, par jsdbt

    I am building a simple video editor in react js. For backend, I am using ffmpeg (python)

    


    I need to set the heading font-size for a (say) 1920x1080 (16:9 aspect ratio) resolution video. In react js, the video dimensions are width :515px, height :289.688px. If I set font-size=20px, how do I ensure that the final video has 'right' (scaled up or down) font size.

    


    That is, in react js, 20px would occupy different space depending upon the width and height of video. But in ffmpeg, once I set the aspect ratio (16:9), fontsize=20px will always occupy same space.
Say, I want heading to occupy exactly one line, and fontsize=16px occupies exactly one line in the reactjs video. But same, 16px may not 'finally' occupy exactly one line in the rendered video.

    


    How should I set the font-size in reactjs, so that I get the correct font-size in video output ?
