[Live-devel] Live555 Proxyserver not working on Android (Nexus5)

[Indu Girish]

Hi Ross,

We are trying to integrate live555 into an android app which is intended to
run on consumer mobile handsets. Adding a route into those devices is
impossible from an app perspective.

We tried to implement an alternate logic ( for ourIPAddress()
GroupsockHelper.cpp) to obtain the IP address and tried. The proxystream
url changed to the obtained ip address instead of 0.0.0.0. But couldn't
connect to the stream.

We also tried to change the
SendingInterfaceAddr = INADDR_ANY;
ReceivingInterfaceAddr = INADDR_ANY;

part from INADDR_ANY to the IP address of the interface (including all the
permutations). Still it didn't work.

Even when the ip in the supplied url is 0.0.0.0 we can tell that the server
is listening for a connection. When we tried to telnet into IP of the
device and port 8554, connection is established and we did get "400 bad
request" reply from the server.

Do we have any other means to solve this issue by modifying the source code?



Thanks & Regards,
Indu
