Fix freeze/crash on seeking

When the parser was reset it did not forget about the last pts, which might cause metronom to freeze.
On flush the cached vo_frame_t was kept in case the previously decode produced a 1st field and the decoder was waiting for 2nd field now. As on flush all images are released after drawing this could point to a invalid vo_frame_t
