Before creating the NDI Input in Zixi Broadcaster, you must configure at least one transcoding profile that meets the following requirements:
Disable Copy GOP from source - NDI sources can be transcoded using any of the available transcoding profiles, however it is NOT possible to enable the Copy GOP from source feature. Since all frames in the original NDI source are uncompressed, Zixi cannot know which frames were i-frames in the stream, so the GOP length should be configured in the GOP [frames] parameter of the transcoding profile.
No Keep Original - when configuring the stream, it is possible to remove the video or audio from the stream, however it is NOT possible to keep the original video or audio, as they are originally uncompressed.
No RAW Video/Audio - transcoding profiles with RAW Video and/or RAW Audio will be filtered out and will not appear in the Video profile/Audio Profile fields on the NDI Input screen.
No Keep Aspect Ratio - NDI inputs can be resized but not padded with black bars. Enabling the “Keep aspect ratio” checkbox in the transcoding profile will cause the transcoder to fail.
For detailed instructions on how to configure transcoding profiles, see Broadcaster Transcoder section.
