The implementation of the switch_ratio command was hacky and called mpcodecs_config_vo() to reconfigure the filter/VO chain from under an existing decoder. This call no longer worked properly with vd_ffmpeg after that started using mpcodec_config_vo2(). Add new video decoder control command VDCTRL_RESET_ASPECT and use this to tell vd_ffmpeg to reinitialize the output chain properly.
