webrtcrecorder no record file but only: [warn] [streamrecorder.cpp(118)] Dropping initial mono samples #217

Closed demobin8 closed 6 years ago

demobin8 commented 6 years ago

webrtcrecorder sample

  1. build webrtcrecorder sample with webrtc and ffmpeg following: libsourcey doc, successed
  2. settup https enviroment following: #131 , successed
  3. modify source code, record only audio(course my pc do not have a camera), successed

modify src/webrtc/samples/webrtcrecorder/config.h

...
#define OUTPUT_FORMAT av::Format("AAC", "aac", av::AudioCodec("AAC", "libfdk_aac", 2, 44100, 64000, "s16"));
...

modify src/webrtc/samples/webrtcrecorder/signaler.cpp

...
    //auto videoTracks = stream->GetVideoTracks();
    //if (!videoTracks.empty())
    //    _recorder->setVideoTrack(videoTracks[0]);
...

recompile webrtcrecorder modify src/webrtc/samples/webrtcrecorder/client/assets/symple.player.webrtc.js

...
        // The `MediaStreamConstraints` object to pass to `getUserMedia`
        this.userMediaConstraints = player.options.userMediaConstraints || { 
            audio: true, 
            video: false
        }
...

restart server with node app everything looks fine but i cant stop the recording by click stop button except close the browser, and i cann't find any record file, the webrtcrecorder show this message:
