• Cannot link executable NDK ffmpeg - Android 7 Nougat

  11 janvier 2017, par Basit Ali

  I am using ffmpeg in my project and it was working fine until I tried it on Android 7.

  ProcessBuilder builder = new ProcessBuilder(ffmpegCommand);
  
  Map env = builder.environment();
  
  env.put("LD_LIBRARY_PATH", "/data/data/uk.org.humanfocus.hfi:$LD_LIBRARY_PATH");

  When I read the output it return me the following error :

  CANNOT LINK EXECUTABLE "/data/data/uk.org.humanfocus.hfi/ffmpeg": /data/data/uk.org.humanfocus.hfi/ffmpeg: has text relocations

  Used targeting api 23 as well as 22, still not working.
  Is it related to NDK Apps Linking ?
  How can I fix this ?

• Windows Batch File : for /F read only first line of mylist.txt and delete first line afterwards

  20 mai 2018, par J. J.

  I run a batch script :

  FOR /F "tokens=1" %%F IN (mylist.txt) do C:\VideoConverter\Applications\ffmpeg.exe ^
  
  -f image2 -loop 1 -framerate 0.1 -i "%%~F" -i "%~dpn1.mp3" -codec:v libx264 ^
  
  -s 1920x1080 -acodec copy -strict experimental -movflags faststart -t 00:10:10.00 ^
  
  -f mp4 "%~dpn1.mp4"

  In my folder are the following files :

  file001.mp3
  
  file002.mp3
  
  file003.mp3

  mylist.txt contains :

  pic001.jpg 
  
  pic002.jpg 
  
  pic003.jpg

  At the moment the script creates 3 videos with 3 different background images for every mp3 in the folder. This is wrong.

  I want to create only these three videos.

  video 1 = file001.mp3 + pic001.jpg (line1) 
  
  video 2 = file002.mp3 + pic002.jpg (line2)
  
  video 3 = file003.mp3 + pic003.jpg (line3)

  Can someone help me with the for /f command ? Thank you for your help.

• Can't upload huge video to google storage. I using "@ffmpeg-installer/ffmpeg" and @google-cloud/storage

  20 juillet 2022, par Dmytro Petskovych

  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 file.

  


  when I upload video, actually I upload six videos, one for each type resolution

  


  for example when I upload video with duration one hour it split on chunk and totally I get more three thousands 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);
