问题 I have a gstreamer pipeline which drops all of its data into an appsink: command = g_strdup_printf ("autoaudiosrc ! audio/x-raw-int, signed=true, endianness=1234, depth=%d, width=%d, channels=%d, rate=%d !" " appsink name=soundSink max_buffers=2 drop=true ", bitDepthIn, bitDepthIn, channelsIn, sampleRateIn); Which usually looks something like, autoaudiosrc ! audio/x-raw-int, signed=true, endianness=1234, depth=16, width=16, channels=1, rate=16000 ! appsink name=soundSink max_buffers=2 drop

问题 Is it possible to detect the codec used in an RTP stream by analyzing the RTP stream alone? I know about the payload type (PT) field in the RTP header -- that can be used to identify codecs that have statically assigned PT numbers. What about the other codecs that use the dynamic PT number range? Are there any heuristics to detect the type of the payload? I'm interested in all kinds of solutions, even if the detection works for one codec only. 回答1: Sure, you can sniff around the packet to see

问题 Xcode reporting SocketStream object is leaking after streams closing. Leak is reliably reproducible on iPhone, but not on Simulator or Mac. Streams are created with CFStreamCreatePairWithSocketToCFHost , then used, closed and released, leaving another SocketStream every time. I checked retain history in Instruments, and found out that every time read and write streams are closed SocketStream has retain count of 2. (my guess is these two retains are done in

问题 I am developing an app with SINCH Platform for VOIP feature. I am performing an app to app call . I am aware that if Callback URL of application Server is set on SINCH Dashboard then it will not trigger DICE (Disconnect Call Event callback) [refer here] event for App to App Call.

问题 I develop a VoIP app with CallKit. In the case that the user receives two incoming calls and he/she accepts one of them the other one will be closed. For example report both incoming calls: reportInComingCall uuid: 70D506FB-6A9D-4111-8828-35DB8F330A26 reportInComingCall uuid: 129A6D67-AC6A-480E-BCD7-ED14F7961CE5 When the user accepts one of them I get this actions from CallKit: perform action: CXEndCallAction uuid: 129A6D67-AC6A-480E-BCD7-ED14F7961CE5 perform action: CXAnswerCallAction uuid:

问题 I have created a VoIP app in iOS using the Sinch library. I am able to make calls successfully, but am having trouble creating the double-height in-call status bar. By this I mean, my call window appears, and on that window I have a button to leave the view and go somewhere else (WITHOUT hanging up the call) and I would like a green double height in-call status bar to be displayed so that I may tap it and return me to call view. When I send the app to the background, I see the double-height

问题 It happens many times that when call is started it doesn't connect and I can't figure out where it is getting stuck. When it happens the callkit ui is already started as I can see that green notification bar. How do I close callkit ui in this case when call hasn't been connected but callKit ui is running in the background? 回答1: If call has ended by the remote side prior to connecting, you need to report the ended call to CXProvider object. provider.reportCall(with: callUUID, endedAt: Date(),
