Enable double rate deinterlacing in Wowza Transcoder

Double-rate deinterlacing uses the individual interlaced fields to create frames at twice the original frame rate of the video. The advantage is that for high motion video, such as sports, motion is more fluid. The disadvantage is that the quality of each frame can be a bit lower.

Note: This feature is in Wowza Streaming Engine™ media server software 4.0.6.02 and later.

To turn on double-rate deinterlacing in Wowza Transcoder, add the following parameter to the Decode/Video/Parameter section of your transcoder template:

<Parameter>
	<Name>deinterlaceDoubleRate</Name>
	<Value>1</Value>
	<Type>Long</Type>
</Parameter>

When enabled, you'll see the following log statement:

TranscoderWorkerVideoDecoder.init[streamname]: Double rate deinterlacing is enabled for this incoming stream.
