• Why am I getting an error for stream #0.1 ?

  30 juillet 2014, par Rob Avery IV

  I’m converting videos using ffmpeg-php. Here is my code :

      // Set our source file
  
      $srcFile = $uploadFilm.".".$film_type;
  
      $destFile = $uploadFilm;
  
      $ffmpegPath = "ffmpeg";
  
  
  
      // Create our FFMPEG-PHP class
  
      $ffmpegObj = new ffmpeg_movie($srcFile);
  
  
  
      // Save our needed variables
  
      $srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
  
      $srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
  
      $srcFPS = $ffmpegObj->getFrameRate();
  
      if($ffmpegObj->hasAudio()){
  
          $srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
  
          $srcAR = $ffmpegObj->getAudioSampleRate();
  
      }else{
  
          $srcAB = 0;
  
          $srcAR = 0;
  
      }
  
  
  
      // Call our convert using exec()
  
      //$command = $ffmpegPath . " -i " . $srcFile . " -ar " . $srcAR . " -ab " . $srcAB . "k -f flv -s " . $srcWidth . "x" . $srcHeight . " " . $destFile;
  
      //$command = "whoami";
  
      $command = $ffmpegPath . ' -i ' .'"'. $srcFile . '" -ar ' . $srcAR . ' -ab ' . $srcAB . 'k -f flv -s ' . $srcWidth . 'x' . $srcHeight . ' "' . $destFile . '" 2>&1';
  
      $outputCommand = array();
  
      $status = 1;
  
      exec($command, $outputCommand, $status);

  The output gives out this error at the end :

  Error while opening encoder for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height

  I know that both $srcAB and $srcAR have values because this is the command this being ran :

  ffmpeg -i source -ar 48000 -ab 160k -f flv -s 1920x1080 destination

  Of course, after the command is executed, the "convert video" has a size 0, which means it didn’t convert it.

  What am I missing here ?

• configure : check $as first before using $gas as GNU as

  5 août 2014, par Janne Grunau

  configure : check $as first before using $gas as GNU as
  llvm’s integrated assembler supports the AArch64 asm on darwin since
  
  August 2014. So check $as first before using gas-preprocessor.pl via
  
  $gas. Makes the checks specific for that the architecture specific asm
  
  needs. PPC Altivec and AArch64 needs on ’:vararg’ for macro arguments.
  
  Arm needs in addition the ’.altmacro’ directive.

• make video from image file using ffmpeg

  4 août 2014, par Roylisto Putra Pradana

  i have 64 images sequence and i want to make a video using that images.

  you can download the images here

  i use ffmpeg in ubuntu.
  here’s my command

  ffmpeg -r 60 -f image2 -s 1360x768 -i "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/tmp/result%d.png" -vcodec libx264 -crf 20 "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/render/test.mp4"

  it works but only 39 images has generated to a video. My question is why ffmpeg not render all images in that folder into a video, what is my mistake and how to solve it ?
