@Chad-Sweet @modaltb @Alex-Gardner 
I have streamed 2 HiRes (IMX 412) video at 3840x2160 using voxl-streamer on 2 different URLs "rtsp://169.254.4.1:8900/live" & "rtsp://169.254.4.1:8901/live".
Is it possible to stream 2 videos on same port say 8900 and just change /live1 and /live2 extension ?
e.g stream 1=> rtsp://169.254.4.1:8900/live1
      stream 2=> rtsp://169.254.4.1:8900/live2

@Vaibhav-Usapkar You would need to modify the voxl-streamer source code but should be fairly straightforward.

@Eric-Katzfey @Chad-Sweet @modaltb I tried to build the voxl-streamer code with some edits, However I am having some package locating errors encountered while building it as shown in below pic

 I tried to locate the packages as shown below, but unable to locate it

Could you suggest what could be done here.

@Vaibhav-Usapkar You need to do all that in the build docker, not in the host environment.

@Vaibhav-Usapkar https://gitlab.com/voxl-public/voxl-sdk/services/voxl-streamer/-/tree/dev#prerequisites has some instructions. I have a feeling they are not complete but should be good enough to get you going. Let us know if there are any obvious problems with the documentation.

@Eric-Katzfey  Yes I have followed the instructions on that link but still the same error persists

@Vaibhav-Usapkar Please run the command to install the build dependencies before trying the build. For example ```./install_build_deps.sh  qrb5165 stable```. The documentation left that step out so I'll update the documentation. Sorry for the confusion.

Hi @Eric-Katzfey, even after running "./install_build_deps.sh" command the issue persists. 
Do i need to change any paths or install these libraries what do you think ?

@Vaibhav-Usapkar Looks like there is something wrong with your emulator. How are you launching the docker? Are you using `voxl-docker -i qrb5165-emulator`?

## Reply by Vaibhav Usapkar · 2023-02-14 04:35:43 UTC (in reply to Eric Katzfey)

@Eric-Katzfey launching with the command 
>> voxl-docker -i voxl-emulator

@Vaibhav-Usapkar Yeah, that is the voxl emulator for VOXL. You need to launch the qrb5165-emulator for VOXL2.
