# FFmpeg VAD Streaming
|
|
|
|
Streaming inference from arbitrary source (FFmpeg input) to DeepSpeech, using VAD (voice activity detection). A fairly simple example demonstrating the DeepSpeech streaming API in Node.js.
|
|
|
|
This example was successfully tested with a mobile phone streaming a live feed to a RTMP server (nginx-rtmp), which then could be used by this script for near real time speech recognition.
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
npm install
|
|
```
|
|
|
|
Moreover FFmpeg must be installed:
|
|
|
|
```bash
|
|
sudo apt-get install ffmpeg
|
|
```
|
|
|
|
## Usage
|
|
|
|
Here is an example for a local audio file:
|
|
```bash
|
|
node ./index.js --audio <AUDIO_FILE> --model $HOME/models/output_graph.pbmm --alphabet $HOME/models/alphabet.txt
|
|
```
|
|
|
|
Here is an example for a remote RTMP-Stream:
|
|
```bash
|
|
node ./index.js --audio rtmp://<IP>:1935/live/teststream --model $HOME/models/output_graph.pbmm --alphabet $HOME/models/alphabet.txt
|
|
```
