• Using ffmpeg dshow option "HP Webcam Splitter" leaves a process running and the webcam light on

  7 septembre 2017, par Matt Mahony

  I am streaming from a webcam using a command line like (simplified) :

  ffmpeg.exe -f dshow -i video="HP Webcam Splitter" -c:v libx264 -an -f rtp rtp://localhost:50041

  When the "HP Webcam Splitter" option is used, it launches a "HPMediaSmartWebcam.exe" process. This is a process used to stream the webcam to more than one process. My problem is when ffmpeg closes, that executable is still running, and it leaves the webcam light on.

  I can manually kill the HPMediaSmartWebcam.exe process, but I’m hoping for a cleaner way to do this. Does ffmpeg have any idea another external process was launched ? Can ffmpeg detect that and close the new process ? Or is this a bug in the HPMediaSmartWebcam.exe program ?

• Can't upload folder with large amount of files to google storage. I using "@ffmpeg-installer/ffmpeg" and @google-cloud/storage

  20 juillet 2022, par Dmytro

  I upload file to google storage using "@ffmpeg-installer/ffmpeg" and @google-cloud/storage in my node.js App.
Step 1. file uploading to fs is in child processes - one process for each type of resolution (totaly six).
step 2. encription (converting to stream)
step 3. upload to google storage

  


  I use "Upload a directory to a bucket" in order to send the video from the client to the Google Cloud Storage bucket.

  


  This way is working fine only with small video.

  


  for example when I upload video with duration one hour it split on chunk and totally I get more three thousands files. But the problem occurs when there are more than 1500 files

  


  So actually i upload folder with large amount of files, but not all of this files are uploaded to cloud.

  


  maybe someone had the similar problem and helps fix it.

  


  


  


  const uploadFolder = async (bucketName, directoryPath, socketInstance) => {
    try {
      let dirCtr = 1;
      let itemCtr = 0;
      const fileList = [];

      const onComplete = async () => {
        const folderName = nanoid(46);

        await Promise.all(
          fileList.map(filePath => {
            const fileName = path.relative(directoryPath, filePath);
            const destination = `${ folderName }/${ fileName }`;

            return storage
              .bucket(bucketName)
              .upload(filePath, { destination })
              .then(
                uploadResp => ({ fileName: destination, status: uploadResp[0] }),
                err => ({ fileName: destination, response: err })
              );
          })
        );

        if (socketInstance) socketInstance.emit('uploadProgress', {
          message: `Added files to Google bucket`,
          last: false,
          part: false
        });

        return folderName;
      };

      const getFiles = async directory => {
        const items = await fs.readdir(directory);
        dirCtr--;
        itemCtr += items.length;
        for(const item of items) {
          const fullPath = path.join(directory, item);
          const stat = await fs.stat(fullPath);
          itemCtr--;
          if (stat.isFile()) {
            fileList.push(fullPath);
          } else if (stat.isDirectory()) {
            dirCtr++;
            await getFiles(fullPath);
          }
        }
      }

      await getFiles(directoryPath);

      return onComplete();
    } catch (e) {
      log.error(e.message);
      throw new Error('Can\'t store folder.');
    }
  };
