• Error : Output format mp4 is not available

  12 avril 2024, par alpaca pwaa

  I'm using fluent-ffmpeg in my nextjs application, I'm trying to process the video and specified a format to stream on my s3 bucket but it keeps on failing. My terminal keeps on throwing "Error : Error : Output format mp4 is not available". I already verify my ffmpeg format "ffmpeg -format" and confirm that it supports encoding and decoding mp4 files. I've already tried solutions from other forums but it's not working for me.

• Video Manipulation with ffmpeg : Troubleshooting Conversion Issues

  26 janvier 2024, par Barno

  I want to manipulate my video using ffmpeg. I retrieve the stream from S3 with the following function :

  


  async function getImageBufferFromS3(imageUrl) {
    const { bucketName, objectKey } = extractS3InfoFromUrl(imageUrl);
    const s3Client = configureS3Client();

    const getObjectCommand = new GetObjectCommand({
        Bucket: bucketName,
        Key: objectKey
    });

    const data = await s3Client.send(getObjectCommand);
    const imageBuffer = await streamToBuffer(data.Body);
    return imageBuffer;
}

async function streamToBuffer(stream) {
    return new Promise((resolve, reject) => {
        const chunks = [];
        stream.on('data', (chunk) => chunks.push(chunk));
        stream.on('error', reject);
        stream.on('end', () => resolve(Buffer.concat(chunks)));
    });
}


  


  Now, I want to use ffmpeg to add text to it. First, I'd like to obtain the "clean" video :

  


  module.exports.createVideoWithTextAndBackground = async (videoBuffer, customText = null) => {
  try {
    if (!customText) {
      return videoBuffer;
    }
    
    const fontPath = __dirname + '/../public/fonts/Satoshi-Medium.ttf';

    try {
      return await new Promise((resolve, reject) => {
        const input = new stream.PassThrough();
        input.end(videoBuffer);

        const output = new stream.Writable();
        const chunks = [];

        output._write = (chunk, encoding, next) => {
          chunks.push(chunk);
          next();
        };

        output.on('finish', () => {
          const resultBuffer = Buffer.concat(chunks);
          resolve(resultBuffer);
        });

        output.on('error', (err) => {
          reject(err);
        });

        ffmpeg()
          .input(input)
          .inputFormat('mp4')
          .toFormat('mp4')
          .pipe(output);
      });
    } catch (error) {
      console.error(error);
      throw error;
    }

  } catch (error) {
    console.error(error);
    throw error;
  }
};


  


  However, I encountered the following error :

  


  Error: ffmpeg exited with code 183: frame=    0 fps=0.0 q=0.0 Lsize=       0kB time=N/A bitrate=N/A speed=N/A


  


  Conversion failed !

  


  I don't face any issues when I don't use ffmpeg. I even tried ffmpeg -i to create a video with text using my console, confirming that ffmpeg works on my computer.
