Note

For OpenFEC, it’s highly recommended to use our fork or manually apply patches from it. The fork is automatically used when using --build-3rdparty=openfec option. It contains several critical fixes that are not available in the upstream.

Note

libuv versions before 1.5.0 may have problems on 64-bit ARMs.

Note

SpeexDSP (libspeexdsp) below 1.2rc3 was part of Speex (libspeex) package.
