The BirdDog Flex 4K OUT is a small NDI to HDMI decoder. It takes a full-bandwidth NDI stream from the network and plays it out on an HDMI 2.0 port. So it often sits behind a confidence monitor, a projector or a screen in the foyer. Showcaller AI connects to the BirdDog Flex 4K OUT through the Bridge App on your show network. Then you change what it shows by voice or chat. The [BirdDog NDI converter integration](/integrations/birddog-ndi-converter/) page lists every Tool Function.

### Choose what the BirdDog Flex 4K OUT shows

First, Showcaller lists the NDI sources the decoder can see. Then it connects the decoder to a source by name, for example “the main program feed”. Because a switch changes the picture, Showcaller asks you to confirm it. After the switch, it reads the decode status to check the new source. It also tells you which source is connected right now. When a source is missing, Showcaller refreshes the list. These functions are in every plan.

### Decode settings, groups and audio

From the Pro plan, Showcaller reads and changes the decode settings. For example, BirdDog lists NDI audio on or off, the screensaver and tally mode. It also sets the decode transport, such as TCP, UDP or multicast. In addition, Showcaller sets the NDI group name, the discovery server and off-subnet sources. Then it sets the analog audio in and out gain and the analog output select. After a change, it reads back the group name, the discovery server and the audio settings. However, decode settings and transport are reported as the converter answered. With Enterprise, Showcaller resets the source list, restarts video or reboots the unit, after you confirm.

### Limits and end of life

The Flex 4K OUT is a decoder only. So Showcaller hides the encode settings for it. There is also no mode switch and no video output interface. BirdDog has announced the end of life of the Flex family. Still, BirdDog says support continues until an end-of-support date. For new decoders, BirdDog recommends the Play or Play Pro.
