Flix Engine Documentation

8.0.17.2

Thank you for licensing the On2 Flix Engine SDK. This SDK provides a framework for embedding the acclaimed On2 Flix multimedia engine in your server-based applications. Flix Engine is able to transcode nearly any type of multimedia input to high-quality Adobe^® Flash Video (FLV and SWF) and other popular formats, including 3GPP, 3GPP2, MOV, and MP4.

Also available for Windows! Flix Engine for Windows provides full COM automation support for access from ASP/ASP.NET, C/C++/C#, ColdFusion, Delphi, Java (via JNI/COM Bridge), PHP, Python, Visual Basic/VB.NET, VBScript, and any other COM-enabled container application or programming language. On2 Flix Engine for Windows is available as a dynamically linked library (DLL).

New Codecs & Container Formats

Flix Engine 8.0.17.0 supports the html5 ready WebM container using VP8 and Vorbis.

Flix Engine 8.0.10.0 now supports MPEG-4 Part 10 standard, commonly known as H.264. Specifically, Flix Engine can now encode video using the H.264 codec and audio using AAC / AAC+, in addition to the already available encoders: On2 VP6 and H.263 video, and MP3 and AMR-NB audio.

Accordingly, Flix Engine is now able to produce the common MPEG-4 container formats, MP4, MOV and 3GPP2.

Another new capability of Flix Engine 8.0.10.0 is the VP6_S encoding profile, which is optimized for encoding higher resolution material destined for playback in low-resource environments, such as older PCs. The standard VP6 encoding profile (VP6_E) is the default. See FE2_VP6_PROFILE in the API reference.

Flash Player Support and AVC Licensing

Please note carefully that, at this writing, no Flash Player release supports MPEG-4 streams. We have added these new codecs and capabilities to Flix Engine in anticipation of our users' future needs, and to expand choice.

Also note that the distribution of AVC/H.264-encoded media is not royalty-free in many cases. Be sure to comply with the H.264 licensing terms available at http://www.mpegla.com and http://www.vialicensing.com.
