• Cant Record Stream Using MediaRecorder In Server ?

  13 avril 2022, par Riyad Zaigirdar

  First I am trying to make a Webrtc peer connection from the browser to the server using SFU model.

  


  Here is the post request which makes the webrtc peer connection from the browser to the server(SFU)

  


  app.post("/broadcast", async ({ body }, res) => {
  const peer = new webrtc.RTCPeerConnection({
    iceServers: [
      {
        urls: "stun:stun.stunprotocol.org",
      },
    ],
  });
  peer.ontrack = (e) => handleTrackEvent(e, peer); <-- Important
  const desc = new webrtc.RTCSessionDescription(body.sdp);
  await peer.setRemoteDescription(desc);
  const answer = await peer.createAnswer();
  await peer.setLocalDescription(answer);
  const payload = {
    sdp: peer.localDescription,
  };

  res.json(payload);
});


  


  In the handleTrackEvent function, I am getting the stream which I want to start record and save in the server's local storage.

  


  function handleTrackEvent(e, peer) {
  console.log(e.streams);
  senderStream = e.streams[0];
  var recorder = new MediaStreamRecorder(e.streams);
  recorder.recorderType = MediaRecorderWrapper;
  recorder.mimeType = "video/webm";
  recorder.ondataavailable = (blob) => {
    console.log(blob);
  };
  recorder.start(5 * 1000); <-- Error generator
}


  


  But when try to start the recording and get the blob in 5 sec intervals, it gives me "MediaRecorder Not Found" ...

  


  Passing following params over MediaRecorder API. { mimeType: 'video/webm' }
/Users/tecbackup/webrtc-peer/node_modules/msr/MediaStreamRecorder.js:672
            mediaRecorder = new MediaRecorder(mediaStream);
            ^

ReferenceError: MediaRecorder is not defined


  


  I am very new to webrtc, I need some suggestion to save the live stream from the browser to the server....In future, if find the blob, then I will save the blobs sequentially in a mp4 file in the server. Then, on runtime i start pressing ffmpeg in that mp4 file to get 240p, 360p, 720p ts files for hls streaming

  


• Compiling x264 on a Mac : "No working C compiler found" and "arm-linux-androideabi-gcc : command not found"

  29 novembre 2014, par Xavi Gil

  I am trying to compile the x264 library for Android, following this post.

  I have cloned the x264 project git clone git://git.videolan.org/x264.git and tried to compile with the following configuration :

  NDK=~/development/android-ndk-r10c    
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
  
  PLATFORM=$NDK/platforms/android-21/arch-arm
  
  
  
  ./configure \
  
  --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
  --sysroot=$PLATFORM \
  
  --host=arm-linux \
  
  --enable-pic \
  
  --enable-static \
  
  --disable-cli

  The problem is that I get a No working C compiler found. error.

  The conftest.log output :

  $ cat conftest.log 
  
  ./configure: line 153: arm-linux-androideabi-gcc: command not found

  But the arm-linux-androideabi-gcc is the toolchain’s bin folder !!

  Looking at this other question it looks like for some reason, even though the file exists, since it is a 64bit Mac, it won’t execute the arm-linux-androideabi-gcc file and will return this weird error and log.

  I am in a Mac OS X 10.10 and I have installed the XCode Command Line Tools :

  $ xcode-select -p
  
  /Applications/Xcode.app/Contents/Developer

  GCC version :

  $ gcc --version
  
  Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

  Can anyone tell me how to fix this please ?
