[FFmpeg-cvslog] avplay: Don't try to scale timestamps if the tb isn't set

ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Fri Apr  6 13:51:34 2012 +0300| [951e715cebfaffced7f13c1525771ff917fe1d38] | committer: Martin Storsjö

avplay: Don't try to scale timestamps if the tb isn't set

If get_filtered_video_frame failed above, tb might not be
initialized at all, so don't scale using it.

This fixes cases where avplay could crash if aborting
avformat_find_stream_info with ctrl+c.
