crashed when webrtcstreamer have a new connection #279
Description
first run the node app, and run webrtcstreamer, and webrtcstreamer will crashed after open http://localhost:4499.
I found the crashed point at webrtc/src/webpacketsource.cpp, do Start and SetCaptureFormat that will make crashed:
cricket::CaptureState VideoPacketSource::Start(const cricket::VideoFormat& format)
{
LDebug("Start")
// NOTE: The requested format must match the input format until
// we implememnt pixel format conversion and resizing inside
// this class.
RTC_CHECK(_captureFormat == format);
if (capture_state() == cricket::CS_RUNNING) {
LWarn("Start called when it's already started.")
return capture_state();
}
if (_source)
_source->attach(packetSlot(this, &VideoPacketSource::onVideoCaptured));
SetCaptureFormat(&format);
return cricket::CS_RUNNING;
}
this is strange, I don't known where's wrong, please help me.
