• "Cannot find ffmpeg" error when using 'audioconcat'

  2 janvier 2020, par Mosukoshide

  I would like to concatenate three ’.oga’ sound files using audioconcat, however whenever I try to do so, I am met with this error :

  Error: Error: Cannot find ffmpeg
  
      at /root/user/node_modules/fluent-ffmpeg/lib/processor.js:136:22
  
      at /root/user/node_modules/fluent-ffmpeg/lib/capabilities.js:123:9

  ffmpeg stderr: undefined

  I have already installed ffmpeg with the flags that were listed on the audioconcat npm page like this :

  npm i ffmpeg --enable-libass --enable-libmp3lame

  And the code I am trying to run looks like this :

                  audioconcat(audioFiles)
  
                  .concat(`main.oga`)
  
                  .on('start', function (command) {
  
                    console.log('ffmpeg process started:', command)
  
                  })
  
                  .on('error', function (err, stdout, stderr) {
  
                    console.error('Error:', err)
  
                    console.error('ffmpeg stderr:', stderr)
  
                  })
  
                  .on('end', function (output) {
  
                    console.error('Audio created in:', output)
  
                  })

  I’m not sure how to fix this problem...

• Running ffmpeg in PHP exec() encounter "libstdc++ not found" error

  5 octobre 2019, par mitra razmara

  When I run ffmpeg (3.4.6) in "terminal" (ubuntu 18.4), it works fine ; But when I run it through "PHP exec()" (PHP 7.3)

  exec('ffmpeg 2>&1', $output);
  
  foreach ($output as $key => $value) {
  
    echo $value.'<br />';
  
  }

  it gives me below output.

  If I run this

  exec('which ffmpeg 2>&1', $output);

  I get below output

• Error "EVP_DecryptFinal_ex:bad decrypt:crypto\evp\evp_enc.c:570" appears even after specifying -md5 sha256 in command line

  29 septembre 2019, par shantanu goel

  I have the following query. Could anyone please suggest me a solution.

  I’m working on decryption of .ts file for the first time. I have downloaded multiple .ts files from the source and have merged them but not able to decrypt the file. Even if it gets decrypted the size of the file is zero bytes.

  Command I’m using :

  aes-128-cbc -d -in D:\Test\joined_files.ts -out D:\Test\decrypt_I00100000.ts -iv 0 -K 313863756468736b63646b6a616b -md SHA256

  The error I’m getting :

  the hex string is too short, padding with zero bytes to the length
  the hex string is too short, padding with zero bytes to the length
  bad decrypt
  1132:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:crypto\evp\evp_enc.c:570 :
