IJKPlayer was frozen after playing several minutes on bad network situation.

When the network is bad, the ijkplayer can play normally at first. After a few minutes it would be frozen, and through the hud info view, I can get such information:
tcp-spd: 0
fps:21/16 (the value also never change).
v-cache: 0 msec, 0 B, 0 packets (the value also never change).

But if I reinit a ijkplayer, it will be ok and works very well. I think maybe somewhere has a deadlock in the program.

Start by reproducing playback under a bad network and monitor the HUD info view, especially tcp-spd, fps, and v-cache. Trace the player state when those values stop changing; done means playback recovers without reinitializing IJKPlayer and the cache metrics resume.
