 I am getting a crash in avcodec on a particular wmv file. The file is
 123MB and I think likely any effort to make a cut will not produce the
 crash. This file will not play anywhere but ffmpeg attempts to play it.
 Mostly, I would like to be able to detect an indication that this is a bad
 file but not seeing how to do that at present since everything appears to
 open and initialize fine.

 ffplay will play it to point of crash. Same thing in my own app. Let me
 know how I should best proceed from here. Since the following indicates
 that decoding will likely fail, is there an error set that I can pick up
 and use ?
