• Convert RTMP to RTP in iOS application for sending it to Kurento Media Server

  4 janvier 2019, par utkarsh agarwal

  Working on implementing Screen Sharing(Replay Kit) in iOS app using Kurento Media Server. I get CMSampleBuffer which follows RTMP protocol. But Kurento doesn’t support RTMP. It does support RTP. Is there a way to convert from RTMP to RTP. I read about ffmpeg but it seems to need to be implemented on server side which require a lot of change in current flow something like below
  [Browser] -> RTMP -> [Node_Media_Server(srs)] -> RTMP ->

  [FFmpeg] -> RtpEndpoint -> [Kurento] -> WebrtcEndpoint -> [Browser]

  Will this flow be efficient enough ?

  Is there a way to convert it from client side i.e iOS application ?

• How to send continuous stream of frames to server most efficiently

  27 avril 2019, par Duthopi

  I am trying to send frames from a local camera (raspberry pi camera, but could also be my laptop’s webcam) to a Google cloud instance, on which I am running AI processing of the frames.

  I am managing to send frames captured through opencv via http (i.e. tcp ??) and receiving them on a flask server. When the flask server is running locally I can get good fps (50+ fps for image size 640x480), however once I send the frames to a flask app on the google instance the fps drop drastically to 5fps.

  How I currently send frames :

  while True:
  
          frame = vs.read() #Separate thread, using cv2 to get the frame
  
  
  
          ret, jpeg = cv2.imencode('.jpg', frame)
  
          imgdata = jpeg.tobytes()
  
          response = requests.post(
  
              url='http://<ip address="address" of="of" google="google" instance="instance">:<port>',
  
              data= imgdata,
  
              headers={'content-type':'image/jpeg'},
  
              )
  
  </port></ip>

  I see two problems with this :
  1 - using tcp means I am slower than udp protocol, however udp is limited in byte size. Correct me if I am wrong, but it seems very complex to send truncated frames and put them back together on the server..
  2 - Even if I had udp working, there is no compression of frames, so I will never reach an efficient transfer

  I expect the answer to be something like using ffmpeg, but so far I only figured out how to stream frames on a local port with ffmpeg, I do not know if it is possible to send frames to a remote server.

  Any recommendations on the best way forward ?

• How to stream live from iphone camera to server using rtsp ?

  12 septembre 2014, par Vishal Gupta

  I am using AVCaptureSession to record a video and audio of user. I am getting real time video and audio streams independently. I am able to encode them using h264 encoder and aac encoder respectively. Now I am not getting how to multiplexing them both and make a stream ? How to send them to specific server url which is protected by userName and Password ? If it can be done using RTMP also then also it’s fine.

  I have taken a reference from here ! But I am not getting much out from this.

  Is there any RTSP library project which can help me ?

  I have been struggling in it from a long.

  Is there any solution to my problem ?

  Thanks in advance.
