[FFmpeg-user] Replacing video segments with JPGs?

[Gilles]

Hello

I need to edit a video stream where some segments will be replaced
with JPGs.
This is a conference where the camcorder was shooting the speaker the
whole time, and I need to insert some JPGs from the PowerPoint
presentation. I don't know how this action is called in video-speak.

Can ffmpeg do this, eg. something like:

'at 1mn30 for 10 secondes, replace video with JPG
ffmpeg -i input.mpg -ss 01:30 -t10 -v:insert myfile.jpg output.mpg

Thank you.
