There is a rather simple implementation of format change in lavfi: have on each input a boolean flag "can_deal_with_format_change". If a frame with a different format arrives on a filter that does not have the flag, just insert the scale/aresample filter on the link to force the format to be the same. It is not entirely optimal, but it is quite simple and does the work. And it could probably be implemented independently of my changes. But I do not want to spend time on it before finishing this, or it will never end. (Actually, I think we had something like that for buffersrc but it disappeared at some time. avconv also has some very strange code to handle format changes.) > At current rate your lavfi changes will never get in, which sucks. Which is why I would like to be authorized to ignore this kind of hiccups. Format change does not currently work, this particular case used to work only by chance. Can I break it and repair it later?
