• avcodec/mpegvideo : Deprecate mpeg_quant option for codecs != MPEG-4

  6 avril 2021, par Andreas Rheinhardt

  avcodec/mpegvideo : Deprecate mpeg_quant option for codecs != MPEG-4
  mpeg_quant may only be set for MPEG-4 and MPEG-2, yet for the latter
  
  it is no option as the code acts as if it were always set.
  
  So deprecate the option for all codecs for which it makes no sense.
  Furthermore, given that the code already errors out if the option is set
  
  for a codec that doesn't support it we can restrict the range of
  
  the option for all these codecs without breaking something. This means
  
  that the checks for whether mpeg_quant is set for these codecs can be
  
  removed as soon as AVCodecContext.mpeg_quant is removed.

• How to fix av_interleaved_write_frame() broken pipe error in php

  31 mars, par Adekunle Adeyeye

  I have an issue using ffmpeg to stream audio and parse to google cloud speech to text in PHP.

  


  It returns this output.
I have tried delaying some part of the script, that did not solve it.
I have also checked for similar questions. however, they are mostly in python and none of the solutions actually work for this.

  this is my PHP code

  


  require_once 'vendor/autoload.php';

    putenv('GOOGLE_APPLICATION_CREDENTIALS=' . __DIR__ . '/xxx-45512-be3eb805f1d7.json');

    $fp = popen($ffmpegCmd, "r");
    if (!$fp) {
        die("Failed to open FFmpeg stream.");
    }
    sleep(5);

    try {
        $client = new SpeechClient(['transport' => 'grpc', 'credentials' => json_decode(file_get_contents(getenv('GOOGLE_APPLICATION_CREDENTIALS')), true)]);
    } catch (Exception $e) {

            yield fread($fp, 4096);
        }
    }
    
    $responses = $client->streamingRecognize([
    'requests' => (function () use ($configRequest, $fp) {
            yield $configRequest; // Send initial config
            foreach (streamAudio($fp) as $audioChunk) {

        foreach ($response->getResults() as $result) {
            $transcript = $result->getAlternatives()[0]->getTranscript();
            // echo "Transcript: $transcript\n";
    
            // Insert into the database
            $stmt = $pdo->prepare("INSERT INTO transcriptions (transcript) VALUES (:transcript)");
            $stmt->execute(['transcript' => $transcript]);
        }
    }
    
    
    pclose($fp);
    $client->close();


  


  I'm not sure what the issue is at this time.

  


  UPDATE

  


  I've done some more debugging and i have gotten the error to clear and to stream actually starts.
However, I expect the audio to transcribe and update my database but instead I get this error when i close the stream

  


  

  


  this is my updated code

  


      $handle = popen($ffmpegCommand, "r");

    try {
        $client = new SpeechClient(['transport' => 'grpc', 'credentials' => json_decode(file_get_contents(getenv('GOOGLE_APPLICATION_CREDENTIALS')), true)]);
    } catch (Exception $e) {
        echo 'Error: ' . $e->getMessage(); 
        exit;
    }
    
    try {
    $recognitionConfig = (new RecognitionConfig())
        ->setAutoDecodingConfig(new AutoDetectDecodingConfig())
        ->setLanguageCodes(['en-US'], ['en-UK'])
        ->setModel('long');
    } catch (Exception $e) {
        echo 'Error: ' . $e->getMessage(); 
        exit;
    }
    
    try {
        $streamConfig = (new StreamingRecognitionConfig())
        ->setConfig($recognitionConfig);
    } catch (Exception $e) {
        echo 'Error: ' . $e->getMessage();
        exit;
    }
    try {
        $configRequest = (new StreamingRecognizeRequest())
        ->setRecognizer("projects/$projectId/locations/global/recognizers/_")
        ->setStreamingConfig($streamConfig);
    } catch (Exception $e) {
        echo 'Error: ' . $e->getMessage(); 
        exit;
    }
    
    $stream = $client->streamingRecognize();
    $stream->write($configRequest);
    
    mysqli_query($conn, "INSERT INTO transcriptions (transcript) VALUES ('bef')");
    
    while (!feof($handle)) {
        $chunk = fread($handle, 25600);
        // printf('chunk: ' . $chunk);
        if ($chunk !== false) {
            try {
                $request = (new StreamingRecognizeRequest())
                        ->setAudio($chunk);
                    $stream->write($request);
            } catch (Exception $e) {
                printf('Errorc: ' . $e->getMessage());
            }
        }
    }
    
    
    $insr = json_encode($stream);
    mysqli_query($conn, "INSERT INTO transcriptions (transcript) VALUES ('$insr')");
    
    foreach ($stream->read() as $response) {
        mysqli_query($conn, "INSERT INTO transcriptions (transcript) VALUES ('loop1')");
        foreach ($response->getResults() as $result) {
            mysqli_query($conn, "INSERT INTO transcriptions (transcript) VALUES ('loop2')");
            foreach ($result->getAlternatives() as $alternative) {
                $trans = $alternative->getTranscript();
                mysqli_query($conn, "INSERT INTO transcriptions (transcript) VALUES ('$trans')");
            }
        }
    }
    
    pclose($handle);
    $stream->close();
    $client->close();```
