  • CPU spike when transitioning from a still image

    21 avril 2016, par lagnat

    After streaming a still image (with x264) for a long period of time, the transition to live video makes the CPU spike to 100% for a period of time proportionally equal to how long the still image was streaming. More specifically, transitioning after a minute will result in a CPU spike lasting about 15 seconds. Transitioning after 30 minutes will result in that spike lasting closer to 3 minutes.

    Does this symptom make any sense and is there anything I can do about it ?

  • Insert picture into an mp4 video, probably using ffmpeg

    16 février 2019, par vivanov

    I need to insert an image into a video of mp4 format. The image has smaller dimensions than the video, will appear after the video starts, say, after a minute and a half at certain x, y coordinates of the video frame, will stay on (full opacity) for some time and then will disappear before the video finishes.

    It would also be good if the image "fades in" / "fades out" when appearing / disappearing from the video.

    I would like to do that using the latest ffmpeg 4.1.1, although I am also open in using other opensource programs that run under linux if it would be achieved easier.

    I have the ffmpeg build with --enable-gpl --enable-libx264 --enable-libvpx if this may help.

    Thank you for your help !
