Failed to stream video about tobiiglassespycontroller

Hi @bwang514,
you are right, the code works only using IPv4 address.
I wasn't able to access any video streaming of the glasses with IPv6 address, even using VLC software.

What about your experience? Did you try to access the /live/scene using IPV6?

Hey @bwang514,
i experienced the same issue while trying to stream the scene camera video.
I solved it by adding port 8554 to the call, which is mentioned in the tobii developers guide.

cap = cv2.VideoCapture("rtsp://%s:8554/live/scene" % ipv4_address)

Hi @FranzAlbers,

this doesn't work for me. In your example, are you using IPv6 or IPv4 address ?
Please can you paste here the complete URI provided as argument to the VideoCapture?

[FranzAlbers]

I am using an IPv4 address and the Tobii Glasses are connected via Ethernet. I couldn't access the stream using IPv6 either. The complete line of code would be:

cap = cv2.VideoCapture("rtsp://192.168.0.121:8554/live/scene")

Without the port in the URI the connection is refused. The glasses are on 1.25.3-citronkola.

Hi @FranzAlbers,

thank you so much for your feedback. I run successfully the video streaming with LAN using IPv4!!
I will change the code and the documentation in the following releases, before closing the issue.

Just to clarify, IPv4 with LAN is feasible only if a DHCP server is present in the network. In your example, the "192.168.0.121" is the address that the glasses receives from the DHCP server present in your network.

@bwang514: Did you try setting a DHCP server in your network and adding the port in the URI as suggested by @FranzAlbers ?
