The reason I would like it to avoid recompression is to make sure the machine have enough resources to do its job. At the moment my test laptop uses 40% CPU on a quarter of the intended resolution, and it was said that liquidsoap would probably not be able to go beyon 500x500, while we would really like to work at 720x432 for the Internet stream and a lot higher for the broadcast stream. > The resolution and framerate settings that you've seen > (frame.video.width/height/rate) are global parameters determining > liquidsoap's internal (raw) video streaming format.

Sure, I can imagine a lot of cases where it would be hard to guess the value, but for the simple and I suspect common case, it would be fairly simple to get values from the first input file. When liquidsoap is asked to work as a pass-throught processor, it is very surprising to see that the resolution, framerate and bandwidth have changed in the output. > This part might be more or less difficult depending on your precise > needs and the guarantees on that XML file: is it possible that one > files hasn't ended when another starts? what do you want to do in > that case? Yes, this is possible, and in this case the playing file should be interrupted and the other file started. If someone try to schedule a 40 minute program in a 30 minute slot, the next program will not be pushed back and the incorrectly scheduled program will only get their allocated 30 minute slot.
