If there is input like DVB-T streams it can change aspect ratio

Haven't tested yet, but seems like a good idea. Are there other
parameters that would make sense to support reconfiguration for?
Can think of stuff like bitrate and the like, but there is no proper
interface to support changing them at runtime.

In realtime only aspect ratio was most common, but inputs can change
resolution and frame_rate, both could be also dynamicaly changed in encoder.
For example for resolution there is n MaxWidth & MaxHeight which could
differ from actual encoding width and height, but i think this is not
supported in current ffmpeg.
