I have played also removed the three options target-duration, max-files and playlist-length (so defaults are used) and that made no difference. the playlist file is never created.
What am I missing?
Some additional news. I added multipartdemux before jpegdec and now I get a playlist file but when I goto view the video I only get 1 picture. I do see the content being updated now in the playlist file I see the ts files being created - but I still just got the one image.
