(Nor in avplay btw)
Wouldn't argue, but if with avplay I can at least see video and listen sound, with ffplay I only see freeze video and listen loop sound.
Just, my media player for Windows, which use libavcodec, is crashing when I try to playback this file, because of libswscale. So I tryed to check this file in ffplay, and see that problem not in my code, so I assumed its a ffmpeg bug.
Changing pixel format with avfilter enabled
Hm. Pixel format is changing when I try to play this file? (my media player doesn't use avfilter)
Sorry for my bad English.

Replying to Kraken:

Yes, that may be reason why swscale crashes for you. See ffplay.c with CONFIG_LIBAVFILTER set to 0, it gets a cached swscaler context for each frame because of possibly changing pixel format.
Changing pixel format with avfilter enabled is not supported yet in ffplay. (Nor in avplay btw)
