+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+The encoderDelay parameter has been replaced by two, nDelay and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.

+
+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):
