H264 codec ---------- Mediastreamer 2 uses Cisco's OpenH264 library as H264 codec. OpenH264 is an open source library but H264 is a coding format protected by a patent from MPEG-LA. That's why that bundle does not embed any OpenH264 library and so you will not able to use H264 out-the-box. Fortunatly, Cisco Systems Inc. distribute OpenH264 in its binary form that you can use in Mediastreamer without paying much royalties to MPEG-LA. However, that binary file as a restrictive licence. See http://www.openh264.org/BINARY_LICENSE.txt form more information. Installation procedure ---------------------- The Cisco's provided OpenH264 library is available at this address: http://ciscobinary.openh264.org/libopenh264-@OPENH264_VERSION@-osx64.dylib.bz2 for MacOS http://ciscobinary.openh264.org/openh264-@OPENH264_VERSION@-win32msvc.dll.bz2 for Windows (32 bit) Once you get the library, uncompress it into /lib/libopenh264.1.dylib On Windows, the library must be installed into \bin\openh264.dll
