  • Video ; Zoom to different points with a single render (?)

    31 mai 2021, par RewossKy

    Based on 16 seconds, I want the codes to zoom to the top left for the first 4 seconds, to the bottom left for the next 4 seconds, to the top right for the next 4 seconds, and then to the bottom right for 4 seconds.

    


    Structurally, the codes are ready, but I need small details, I want to render them in one go (without rendering 4 times) and focus every 4 seconds elsewhere.

    


    If you can help me I would be very happy. I couldn't figure it out for days.

    


    'Top left
ffmpeg -y -i input.mp4 -vf "zoompan=z='if(lte(mod(time,16),4),2,1.05)':d=1:x=iw/3-(iw/zoom/2):y=ih/3-(ih/zoom/2):fps=29.97" output.mp4

  • libav / FFMPEG streaming in one encoding, saving as another

    25 février 2018, par user2333829

    I’m using libav on an embedded device. After some effort, I got a fragmented MPEG4 livestream going with it. I am very happy with this now.

    What I’d like to do now is have two outputs from the same input. The first output is what I currently have, which is a web-quality video (lossy @ video rate) being processed in a callback and streamed somewhere. The second output should be a lossless video saved to a file at a much higher framerate.

    I know I can produce the second output independently, but is there a clever way for libav to do these together ? Or do I just do them both independently ?

  • How to generate MPEG-DASH stream with ClearKey DRM using FFmpeg

    15 juillet 2020, par QFSW

    I want to create an MPEG-DASH stream with ClearKey DRM using FFmpeg.

    


    The stream generation is already complete and working (using the C API)

    


    How could I (using either C or the CLI) add ClearKey DRM to the stream ?

    


    Happy to hear answers for both VOD and live as a pointer to get started
