[Libav-user] ‘avcodec_alloc_frame’ was not declared in this scope

[satya gowtham kudupudi]

After a long time I've decided to rebuild my application. So I've compiled
latest ffmpeg and installed. But now when I try to rebuild my application
against latest ffmpeg, I got the following build errors.

libavcodec_util.cpp:156:33: error: ‘avcodec_alloc_frame’ was not declared

Apparently libavcodec API got updated. What is the alternative
implementation for the above errors?
