How to play live streams with a single, static key frame?

I am looking for assistance with getting our self-built encoder to stream cleanly to wowza. We are trying to stream a video from a source provider that only provides a single, static key frame (blank image), rather than constantly updating it. When we attempt to broadcast the stream through wowza, we have to send the key frame about every two seconds or else it will freeze up, and when we do so, the blank image causes the screen to flash blank, ruining the stream quality. Does anyone know if there is a way to send wowza the key frame information in a way that it will NOT attempt to display the image in this way? The stream that just has the keyframe info once at the start plays fine in ffmpeg.
