Subject: [PATCH] libfdk-aacenc: Fix building with libfdk-aac v2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When flushing the encoder, we now need to provide non-null buffer
parameters for everything, even if they are unused.
The encoderDelay parameter has been replaced by two, nDelay and
nDelayCore.

MIME-Version: 1.0

libfdk-aac: Consistently use a proper version check macro for detecting features
The previous version checks checked explicitly for the version
where the version define was added to the installed headers,
making an "#ifdef AACDECODER_LIB_VL0" enough. Now that we have
a need for more diverse version checks than this, convert all checks
to such checks.

libfdk-aac: Don't use defined() in a #define
MSVC expands the preprocessor directives differently, making the
version check fail in the previous form.
Clang can warn about this with -Wexpansion-to-defined (not currently
enabled by default):
warning: macro expansion producing 'defined' has undefined behavior [-Wexpansion-to-defined]

zero rather than returning AVERROR_EOF.
