e-works open codeckpack is the open source collection of codecs used to extend e-works platform functionalities.

The codecpack can be used by:
-
e-works phone/gateway as endpoint codecs.
These codecs can be used in addition to the closed source video codecs provided with the videoconferencing platform. Codecs have to be compiled as Microsoft Windows DLLs. The videoconferencing platform provides settings to specify the location of additional codecs (see videoconferencing platform documentation).
Following codecs are enabled:h264
-
e-works autore for recompressing a recorded videoconference.
ffmpeg library is used to perform recompression of recorded video conferences, so it has to be compiled with support to desired codecs.
Recompression performed by autore is configured through a set of configuration files, describing containers, audio and video codecs, conversion presets (see videoconferencing platform documentation).
In this release the following ffmpeg codec are enabled: mpeg4, h263, h263p, flv1, libfaac, libmp3lame, libx264,libxvid, wmv2, wmav2, pcm_s16le
and the following ffmpeg muxers: asf, avi, flv, mp4, mov, mp3, adts(aac container)
