Replacing corrupt video frames with error-free frames
In addition to replacing missing video frames to ensure a consistent frame rate, with Wowza Streaming Engine 4.8.12, you can now also replace corrupt frames with error-free frames when using H.264 video and Beamr decoding. After enabling missing frame replacement and Beamr decoding, you can enable outputting only error-free frames with the EnforceStrictDecodeSuccess property in your Transcoder template.
