Hi Catalina
FMV already supports streaming video formats, as you noted and Gordon discussed. I don't know if one is recommended over others but if you implement the capabilities noted below, we can seek further advice on the best protocol.
You're facing at least two challenges:
1) You’ll need some technology to stream your video into the internet (presuming you have a real time download - this may be an additional challenge – and note that the real time preview video on most drone controllers is very low resolution, not the same as the video saved to the drone SD card), and
2) insertion of geospatial metadata into the video stream. You've found the geoprocessing tool called the "Video Multiplexer" which works on Pro with a local video file, so you’d need a way to replicate that functionality in real time. Without the geospatial metadata, you can see your video in a window in FMV (ArcGIS with Image Analyst), but you won't have a footprint on the map or access to the FMV tools.
We have been considering this Esri, and it is good to hear feedback from users. We have two new capabilities under consideration, although not yet scheduled:
a) we are exploring the requirements to store, manage, and share video with a new server technology. When that is available, if you can get your (low resolution preview) drone video onto the network, this server would accomplish the multiplexing of the required metadata re: camera location, orientation, field of view etc. and stream the video for exploitation in ArcGIS Pro. You can see some information at https://esriurl.com/MediaServer
b) a separate capability is considered for Site Scan Flight (http://esriurl.com/SSEE) that could provide a solution to getting video onto the network for streaming. It would include at least minimal geospatial metadata regarding camera location and orientation, enabling some basic features regarding sensor and target location (not all features of FMV).
