• how to deal with live raw h264 stream to send over network

  3 novembre 2015, par jinhwan

  what I want to do is that send live camera stream which is encoded by h264 to gstreamer. I already have seen many example which send over network by using rtp and mpeg-ts. But problem is that all those examples assume that the input will be served by fixed file or live stream which is already transcoded in transport portocol like below.

  client :
  gst-launch-1.0 videotestsrc horizontal-speed=5 ! x264enc tune="zerolatency" threads=1 ! mpegtsmux ! tcpserversink host=192.168.0.211 port=8554

  server : gst-launch-1.0 tcpclientsrc port=8554 host=192.168.0.211 ! tsdemux ! h264parse ! avdec_h264 ! xvimagesink

  But, My camera offer the below interface (written in java, actually work on adnroid). The interface offer just live raw h264 blocks.

  mReceivedVideoDataCallBack=newDJIReceivedVideoDataCallBack(){
  
      @Override
  
      public void onResult(byte[] videoBuffer, int size)
  
      {
  
  }

  I can create tcp session to send those data block. But, how can i make those data which is not packed in transport protocol into format which is understable by gstreamer tcpclient ?
  Transcode the original stream in ts format in the camera side can be a solution. But i have no clue to do transcode from non-file and non-transport-format data. I have searched gstreamer and ffmpeg, But I could not derive a way to deal h264 block stream using the supported interface, unitl now.
  Or, Are there any way to make gstreamer to directly accept those simple raw h264 block ?

• C# - Streaming video from IP Camera with overlay to Facebook Live

  6 avril 2018, par Justin Li

  I am currently working on a project where I am trying to have a C# application connect to multiple IP Cameras where I will add an overlay and continue to forward that stream to an RTMP server like Facebook Live. I am currently using the Ozeki Camera SDK to work with my IP Cameras but I have looked into using AForge as well.

  I have everything set up to stream and overlay but I am having some trouble understanding how I can convert video and audio to be stream-able to the Facebook RTMP server. It seems I have to have an encoder for the video but after Googling, I am coming up short with methods of how to achieve this. I am hoping that someone has some experience in this field can give me a hand.

  Thanks in advance.
