[Live-devel] SIGABRT: SingleStep(): select() fails: Bad file descriptor

[Conchi Abasolo]

Hello Ross,

We are having critical problems with versions 30.09.2013 and 01.10.2013
over TCP. We use the live555ProxyServer example to connect to a camera
stream using the following  command

live555ProxyServer -V -t rtsp://
root:camera86 at 192.168.0.86/axis-media/media.amp


Once the backend connection is established, we try to connet to the stream
using a rtsp client, but after the SETUP command the live555ProxyServer
crashes. It happens always and we cannot even see a single frame.

Here you have a little extract of the gdb log (and attached the complete
log):

ProxyRTSPClient["rtsp://192.168.0.86/axis-media/media.amp/"]::continueAfterSETUP():
head codec: H264; numSubsessions 2

        queue:  H264    PCMU

Sending request: SETUP
rtsp://192.168.0.86/axis-media/media.amp/trackID=2 RTSP/1.0

CSeq: 4

User-Agent: ProxyRTSPClient (LIVE555 Streaming Media v2013.10.01)

Transport: RTP/AVP/TCP;unicast;interleaved=2-3

We think maybe the changes introduced in 2013.09.27 version that close some
TCP sockets are causing some instabilities.


Many thanks

Conchi
