[BUG] - No Audio in Home App

[renedivx]

Hello

if i start the Video Stream in Home App i dont have audio sound. If i start with mqtt audio recording i get a .avi file on raspberry where i can hear the audio. Also if i stream the rtsp stream directly with VLC i have audio.

My Dafang audio settings are: audio format: pcmu in rate 8000 out rate 8000 no filter volume max I try also other setiings, but nothing change.

my other problem is if i change in config audo to true, i dont get any livestream in the home app. if i delete "audio": true, complete in config, i also dint get the live steam. the live stream only works if i make "audio": to false. but than i never get audio sound.

i use a raspberry 3 with debian stretch.

i also look at homebridge ffmpeg plugin to find a solution, but nothing works for me.

here is my config

{ "platform": "Dafang", "mqtt": { "hostBroker": false, "port": 1883, "host": "192.168.22.104", "debug": true }, "cameras": [ { "cameraName": "terrasse", "cameraRTSPStreamUrl": "rtsp://192.168.22.69:8554/unicast", "mqttTopic": "haus/terrasse/#", "folder": "/home/pi/kamera/", "recordingDirectoryPathFormat": "DD-MM-YYYY", "recordingFilenameFormat": "DD-MM-YYYY-kk-mm-ss", "accessories": [ { "name": "Bewegungssensor", "type": "richMotionSensor", "threshold": 100000 }, { "name": "Auto Bewegung", "type": "autoMotionTrackingSwitch" }, { "name": "Nachtsichtsensor", "type": "nightVisionSensor", "threshold": 0 }, { "name": "Nachtsicht", "type": "nightVisionSwitch" }, { "name": "Auto Nachtsicht", "type": "autoNightVisionSwitch" }, { "name": "Links", "type": "moveCamera", "axis": "horizontal", "direction": "left" }, { "name": "Rechts", "type": "moveCamera", "axis": "horizontal", "direction": "right" }, { "name": "Hoch", "type": "moveCamera", "axis": "vertical", "direction": "up" }, { "name": "Runter", "type": "moveCamera", "axis": "vertical", "direction": "down" }, { "name": "Video aufnehmen", "type": "recordVideo" }, { "name": "Audio aufnehmen", "type": "recordAudio" }, { "name": "Bild aufnehmen", "type": "captureImage" }, { "name": "RPi Speicher", "type": "storageSensor" }, { "name": "Speicher bereinigen", "type": "clearStorage" }, { "name": "Stream zurücksetzen", "type": "resetFFMPEG" }, { "name": "Helligkeit", "type": "brightness" }, { "name": "Neustarten", "type": "restartSwitch" }, { "name": "Kalibrieren", "type": "recalibrateSwitch" } ], "videoConfig": { "source": "-rtsp_transport tcp -re -i rtsp://192.168.22.69:8554/unicast", "stillImageSource": "-i http://root:ismart12@192.168.22.69/cgi-bin/currentpic.cgi", "maxStreams": 2, "maxWidth": 1280, "maxHeight": 720, "maxFPS": 21, "maxBitrate": 299, "vcodec": "h264_omx", "audio": true, "packetSize": 188 } } ] },

sudo apt-get install pkg-config autoconf automake libtool libx264-dev

download and build fdk-aac

git clone https://github.com/mstorsjo/fdk-aac.git cd fdk-aac ./autogen.sh ./configure --prefix=/usr/local --enable-shared --enable-static make -j4 sudo make install sudo ldconfig cd ..

download and build ffmpeg

git clone https://github.com/FFmpeg/FFmpeg.git cd FFmpeg ./configure --prefix=/usr/local --arch=armel --target-os=linux --enable-omx-rpi --enable-nonfree --enable-gpl --enable-libfdk-aac --enable-mmal --enable-libx264 --enable-decoder=h264 --enable-network --enable-protocol=tcp --enable-demuxer=rtsp make -j4 sudo make install

Change Audio Type in dafang Settings to MP§ solve my Porblem. Now all is working.

For anyone coming across this, and trying to get audio working on MacOS with homebrew, you need to make sure that ffmpeg is compiled with fdk-aac beforehand, but the options have been removed from the ffmpeg install formula.

I followed this https://github.com/justinmayer/homebrew-tap along with these options:

brew install justinmayer/tap/ffmpeg --with-chromaprint --with-fdk-aac --with-librsvg --with-libsoxr --with-libssh --with-tesseract --with-libvidstab --with-opencore-amr --with-openh264 --with-openjpeg --with-openssl --with-rtmpdump --with-rubberband --with-webp --with-zeromq --with-zimg --with-srt --with-libvmaf

Then for the configuration...

On DAFANG: Video Size: 1280x720 Video Format: VBR Bitrate: 1200 Framerate: 30fps Audio Format: MP3 Sample Rate in/out: 16000/16000 Filter: no High pass: deselected AEC: deselected

In the config section for the dafang plugin in Homebridge:

"videoConfig": {
  "source": "-re -i rtsp://192.168.2.223:8554/unicast",
  "stillImageSource": "-i rtsp://192.168.2.223:8554/unicast -vframes 1 -r 1",
  "maxStreams": 2,
  "maxWidth": 1280,
  "maxHeight": 720,
  "maxFPS": 30,
  "audio": true
}
