VOXL2 stream video through /dev/video0
-
Hello, I'm somewhat new to video streaming, networking, and Linux development. I'm working on a VOXL2 running voxl-suite 1.3.4~beta3. In addition, I have an M0173 breakout connected with two M0166 tracking and two M0161 Hires cameras. My current project will only use one of the Hires cameras. I've been able to successfully stream the Hires cam over RTSP using voxl-streamer as a sanity check.
However, my project involves third-party (whom I'm able to contact) software onboard that uses ffmpeg to encode and compress video from /dev/video0 and write it to UDP:127.0.0.1:9976. Is it possible for me to direct the Hires camera to video0 for the software to use? From what I've read, the camera can't be accessed directly via video0 (hence the use of voxl-camera-server). Are there any workarounds here?

@jcai No, but you could look at voxl-streamer. VOXL 2 does all of the encoding for you already, you do not need ffmpeg
-
@Moderator Am I able to specify the IP and port that the stream from voxl-streamer is sent to? Since the third-party software encodes and writes to UDP:127.0.0.1:9976, I'm wondering if it's possible to direct voxl-streamer straight there instead
-
@jcai You can use the
-poption to specify a different port number. The127.0.0.1address is just the home IP address. -
@Eric-Katzfey There might be something about networking that I'm not understanding here.
voxl-streamer by default streams RTSP to <IP>:8900, so for me I can see the stream by going to rtsp://192.168.1.222:8900/live
Just changing the port to 9976 doesn't equate to udp @ 127.0.0.1:9976, does it? -
@jcai It should then be rtsp://192.168.1.222:9976/live. Ah, but you don't want that
livepart on the end?
