Thanks for clarifying. It's not really "caching", but ffmpeg will read the image, decode it in memory, and then won't think about it again. I guess what could work is writing the image as an MJPEG stream (or something similar) to a Linux pipe, which is then read by ffmpeg, but I have no idea how to get the timing for this right. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
