The Transcoder in Wowza Streaming Engine™ media server software supports bi-directional frames (B-frames) when using the Beamr encoder implementation and the Main or High Profile. B-frame generation is turned on by default. The default value is 3, which instructs Transcoder to generate three B-frames between each P-frame.
To change the number of B-frames generated or to disable B-frames for a given <Encode> block, in your Transcoder template, add the following parameter to the Video/Parameters container in the <Encode> block. The Value property specifies the number of B-frames to generate between each P-frame. A value of 0 disables generation B-frames between P-frames.
