[Libav-user] Getting "Increasing reorder buffer" warning

[krishnaks at iwavesystems.com]

I am using FFmpeg library for decoding H264 frames and display it on iPad.
iPad is able to display decoded messages. But the "increasing reorder
buffer" warning is coming continuously. After this I received memory
warning from iPad also.
