According to DJI's documentation, DJI Fly v1.16.0 and later requires a connected microphone to start RTMP livestreaming on the RC 2.
But what if I only want to transmit video without audio?
I'm trying to find a reliable workaround without buying or carrying a physical microphone.
Has anyone successfully tested any of these approaches?
- Using a USB-C audio adapter that registers as a microphone input without an actual microphone attached.
- Using a smartphone as a virtual USB or Bluetooth microphone.
- Emulating a USB Audio Class microphone that provides silent audio.
- Starting an RTMP stream with video only, without DJI Fly enforcing microphone detection.
My goal is simply to send the drone's RTMP video feed to my own receiving application.
I'm particularly interested in solutions that work on a stock DJI RC 2 without rooting or modifying the controller.
Has anyone found a working solution? If so, could you share the hardware, firmware version, and steps?
It would also be great if DJI could make audio optional for RTMP livestreaming.
