Edison: WiFi stream input - USB output (video)

In short: I’m trying to make Edison do the reverse of APsync

Initially, I planned to only control the camera (Panasonic TZ110) via WiFi with Edison.
The camera has built-in WiFi to connect with its app on smartphones.
App interface:

Later, I found that this camera doesn’t output HDMI while recording video so another solution is to use the video from WiFi stream.

The difficult part is sending the video out from the Edison.
My transmitter (SkyZone TX-5D) only takes AV or HDMI but Edison has none of them.

My plan is to output the video via USB port and buy an AV converter but I have little knowledge in this subject.

Anyone willing to help?
If successful, it will work with all Panasonic cameras.
