Partial working in local network #1362

Closed mastersam92 closed 1 year ago

mastersam92 commented 1 year ago

About working in local network without any internet connection: Stream works good when streaming device( transmitter ) and display device( receiver ) both connected to one network BUT none of them ran on device that sharing network.

I.e: Device "1" - connected to local WiFi Device "2" - connected to local WiFi Device "3" - share local WiFi for device 1 and 2 without Internet access

If try to stream from device 1 to device 2 - working If try to stream from device 2 to device 1 - working If try to stream OR receive stream on device 3 - not working

While try to receive stream on device 3 on log all seems OK - peer connections, tracks, etc But instead of some pictures from stream camera - just white screen. But before connections preview is black, after - white and seems as ready to show something but pictures isn't come

Similarly happens if try to stream or receive stream in app but with WebView( and "native" webview's webrtc )

As I think, it may be related to local address device that sharing network. It often 127.0.0.1 for local processes instead of 192.168.x.x for example. But in case serious problems with network address there would be problems with peer connections to, wouldn't there ?

What may be wrong and which workaround may be for this case ?

Expected Behavior

Success transmit and receive streaming

Observed Behavior

Not success

Steps to reproduce the issue

Share WiFi from device without internet access Connect other device Try to stream WebRTC from one device and receive on second or vice-versa

Platform Information

Sounds like a limitation caused by how tethering decides to locally network devices. It might not be giving uninterrupted access to the devices network. Maybe even all sorts of port restrictions.

Possibly out of scope.

Tested on( used ports: 30003 - for https, 30000 - for http ): Few devices with different Android versions On few iPhones with 14 and 16 iOS versions On PC and apple's computers both with Chrome and apple - with Safari

And always one thing: Stream transmit and receive not working on device which share local WiFi network( i.e working as Access Point ). The same device with the same app/webpage, but connected to network that share other device - work perfectly

Is there any known restrictions for it ?

Described case is simple to reproduce even if you have one device + PC

8BallBomBom commented 1 year ago

In a general sense there isn't any restrictions on our end. Simply just a case of whether both ends can communicate with one another within the environment they are in. Different tethering options have all sorts of restrictions/configurations which might not be ideal. Not to mention they could also be enforcing their own local NAT which means routing might be all sorts of wonky.

Try outputting some logs, see what the candidates look like, compare addresses.

What ICE candidates does each device gather? Log them please.

Architecture: Streamer app + signaling server( SocketIO ) together on some device, receiver connecting via IP

Log of success case( stream from Android, watch stream on Chrome, PC. Working in WiFi network from iPhone AP without internet connection ):
