  • Google Speech - Streaming Request Returns EOF Error

    16 octobre 2017, par Josh

    Using Go, I’m taking a RTMP stream, transcoding it to FLAC (using ffmpeg) and attempting to stream to Google’s Speech API to transcribe the audio. However, I keep getting EOF errors when sending the data. I can’t find any information on this error in the docs so I’m not exactly sure what’s causing it.

    I’m chunking the received data into 3s clips (length isn’t relevant as long as it’s less than the maximum length of a streaming recognition request).

    Here is the core of my code :

    func main() {
    

    
    done := make(chan os.Signal)
    
    received := make(chan []byte)
    

    
    go receive(received)
    
    go transcribe(received)
    

    
    signal.Notify(done, os.Interrupt, syscall.SIGTERM)
    

    
    select {
    
    case <-done:
    
        os.Exit(0)
    
    }
    
}
    

    
func receive(received chan<- []byte) {
    
    var b bytes.Buffer
    
    stdout := bufio.NewWriter(&b)
    

    
    cmd := exec.Command("ffmpeg", "-i", "rtmp://127.0.0.1:1935/live/key", "-f", "flac", "-ar", "16000", "-")
    
    cmd.Stdout = stdout
    

    
    if err := cmd.Start(); err != nil {
    
        log.Fatal(err)
    
    }
    

    
    duration, _ := time.ParseDuration("3s")
    
    ticker := time.NewTicker(duration)
    

    
    for {
    
        select {
    
        case <-ticker.C:
    
            stdout.Flush()
    
            log.Printf("Received %d bytes", b.Len())
    
            received <- b.Bytes()
    
            b.Reset()
    
        }
    
    }
    
}
    

    
func transcribe(received <-chan []byte) {
    
    ctx := context.TODO()
    

    
    client, err := speech.NewClient(ctx)
    
    if err != nil {
    
        log.Fatal(err)
    
    }
    

    
    stream, err := client.StreamingRecognize(ctx)
    
    if err != nil {
    
        log.Fatal(err)
    
    }
    

    
    // Send the initial configuration message.
    
    if err = stream.Send(&speechpb.StreamingRecognizeRequest{
    
        StreamingRequest: &speechpb.StreamingRecognizeRequest_StreamingConfig{
    
            StreamingConfig: &speechpb.StreamingRecognitionConfig{
    
                Config: &speechpb.RecognitionConfig{
    
                    Encoding:        speechpb.RecognitionConfig_FLAC,
    
                    LanguageCode:    "en-GB",
    
                    SampleRateHertz: 16000,
    
                },
    
            },
    
        },
    
    }); err != nil {
    
        log.Fatal(err)
    
    }
    

    
    for {
    
        select {
    
        case data := <-received:
    
            if len(data) > 0 {
    
                log.Printf("Sending %d bytes", len(data))
    
                if err := stream.Send(&speechpb.StreamingRecognizeRequest{
    
                    StreamingRequest: &speechpb.StreamingRecognizeRequest_AudioContent{
    
                        AudioContent: data,
    
                    },
    
                }); err != nil {
    
                    log.Printf("Could not send audio: %v", err)
    
                }
    
            }
    
        }
    
    }
    
}

    Running this code gives this output :

    2017/10/09 16:05:00 Received 191704 bytes
    
2017/10/09 16:05:00 Saving 191704 bytes

2017/10/09 16:05:09 Saving 191704 bytes
    
2017/10/09 16:05:09 Sending 191704 bytes
    
2017/10/09 16:05:09 Could not send audio: EOF

    Notice that not all of the Sends fail.

    Could anyone point me in the right direction here ? Is it something to do with the FLAC headers or something ? I also wonder if maybe resetting the buffer causes some of the data to be dropped (i.e. it’s a non-trivial operation that actually takes some time to complete) and it doesn’t like this missing information ?

    Any help would be really appreciated.

  • If I pass this code in Windows console it works, but when I emulate windows console in node.js code doesn't work, and returns unclear error

    22 décembre 2016, par Maxim Cherevatov

    I have code :

    cmd.get(
    
    'trimp3  ant.mp3 ant2.mp3 00:00 00:20',
    
    function(data){
    
        console.log('the node-cmd cloned dir contains these files :\n\n',data)
    
    }
    
);

    If pass this code in Windows console it works well !
    But, when i emulate windows console in node.js this code not work, and returns unclear mistake :

    [!!] ERROR:  "ffmpeg" �� ����� ����७��� ��� ���譥�

    To emulate the use node-cmd.

  • android ffmpeg halfninja av_open_input_file returns -2 (no such file or directory)

    20 janvier 2012, par cdavidyoung

    I have built ffmpeg for Android using the code and method described at

    https://github.com/halfninja/android-ffmpeg-x264

    using Ubuntu running in VirtualBox on windows. I then copied libvideokit.so into the Project\libs\armeabi folder of a Windows copy of the provided projects. From there I was able to run the ProjectTest from Eclipse on my Android device. I can see the ffmpeg code being executed but when it gets to the point of opening the input file it gives me the indicated error. I have noticed some discussion of this problem at

    FFMpeg on Android, undefined references to libavcodec functions, although it is listed on command line

    but the solutions have not helped since the file protocol is enabled in this build and I also tried putting "file :" in front of the filepath to no avail. For completeness I tried setting minimal_featureset=0 to enable all the defaults but this gives me the same error. Below is a snapshot of the logcat from Eclipse showing the output from Videokit with an extra call to LOGE to display the result from av_open_input_file. Any suggestions of things to try would be greatly appreciated.
