[FFmpeg-cvslog] ffplay: flush codec buffers before freeing filters

[Marton Balint]

ffmpeg | branch: master | Marton Balint <cus at passwd.hu> | Thu May 24 23:22:59 2012 +0200| [c2e8691c07ca52de7b6b00ba8f2b30c56fd786d7] | committer: Marton Balint

ffplay: flush codec buffers before freeing filters

We do this to ensure that input_get_buffer is not called from a
frame_worker_thread of a multithreaded decoder when we already freed the
filters.

Fixes occasional segfaults on video stream change.
