unknown type name 'AMFContext1'

[Zeranoe]

AMFContext1 is not defined in amfenc.h, but is references in amfenc.c.

When attemtping to build with AMF support I get:

src/libavcodec/amfenc.c:216:5: error: unknown type name 'AMFContext1'; did you mean 'AMFContext'?

You need AMF 1.4.9 or newer, it includes those new structures. Should update the configure requirements.

[Zeranoe]

Closed, as updating to the git version of AMF resolved the issue.
