Issue

Media upload and media import capabilities are expanded to support additional media formats with the Multi-Format Video Import (MFVI) add-on. If MFVI is installed, uploaded media will be transcoded to MP4 format. Decoding will require the appropriate codecs be present on the machine running Mediasite Transcoder. The transcoder will use codecs installed on the machine for decoding media including the H.264 codec installed by the Mediasite Transcoder.

  1. In Mediasite version 7.2 and later, Multi-Format Video Import is included with your license of Mediasite Video Platform. In earlier versions, it was offered as part of optional My Mediasite module.
  2. Multi-Format Video Import can only be installed on a machine running Mediasite Transcode. Multi-Format Video Import works in tandem with Mediasite Transcode to expand on importing additional media formats
  3. Multi-Format Video Import supports importing additional media formats into Mediasite via:
    1. Media Upload in My Mediasite
    2. Media Upload in Management Portal
    3. Media Import in Management Portal
    4. Media Upload call found in Mediasite API


Multi-Format Video Import uses FFmpeg to decode additional formats. FFmpeg is licensed under LGPLv2.1. In order to meet compliance with the licensing terms of LGPLv2.1, the Customer Care Portal includes a download link for the source code. Multi-Format Video Import by itself can be used to decode media files. However, some application needs to use the published interface to obtain the decoded bytes. Mediasite Transcoder is one such application that uses this interface to request decoded media from Multi-Format Video Import to take forward into the Mediasite eco-system.

Solution

Import of the following media formats is supported by Mediasite. Each file format has variants in terms of file extension as well as common video and audio codecs supported by the format.  Note that files without audio tracks are prohibited from being imported into Mediasite.

Note: If H.264 files are encoded using Flash Media Live Encoder (FMLE), the output files are fragmented. The output files must be flattened before they can be edited in a video editing tool such as Adobe® Premiere® Pro, or before they can be played back in Adobe® Media Player. Adobe provides a command-line flattening tool for this purpose; see http://www.adobe.com/go/learn_fmle_tools. MFVI supports decoding of flattened as well as fragmented files.

Adobe Connect generates Flash media files with VP6 video codec and Nellymoser audio codec.
