  • Programmatically capture X11 region with ffmpeg in C/whatever

    26 février 2013, par zw0rk

    There is an input format option to ffmpeg — x11grab which allows one to capture specified region and output it to file/stream. I'm trying to do the same thing programmatically, but i haven't found any non-basic tutorials/reference for ffmpeg API.

    I wonder, how it is possible to open x11 region with avformat_input_file or something like this. Or should i do it with XCopyArea/etc ?

    (Any programming language will satisfy)

  • How to make words in ASS subtitles appear one at a time ?

    21 septembre 2022, par ThaDon

    I am trying to burn subtitles into a video such that they appear in a word-by-word fashion instead of all at once.

    



    What I mean by this is, a word will appear, then another word will appear next to it, and so on. Eventually the line will clear, then repeat.

    



    Example :

    



    A video shows a person speaking about chess. Subtitles at the bottom of the screen say “winning”. Moments later, the subtitles change to “winning a”, then “winning a piece”, later “winning a piece now” and so on. Each consecutive word instantly appears in whole, but each word only appears when the speaker says it.

    



    I thought I could create an Advanced Substation Alpha file where subtitles share the same end-time but differing start times, however FFMPEG doesn't seem to cope very well when rendering the file :

    The idea being that I'm would appear, then 1 second later a would show up next to it followed by subtitle a half second later
