  22 décembre 2015, par user3653474

  I am converting video to .mp4 format, but when i convert video using ffmpeg using the following command :

  exec('D:\wamp\bin\ffmpeg.exe -y -i D:/wamp/www/upload_google_drive/output.flv -c:v libx264 -crf 19 -preset slow -c:a aac -strict experimental -b:a 192k -ac 2 D:/wamp/www/upload_google_drive/w3.mp4 2>&1',$output);

  in some of the devices it does not run. The message which appears is

  Cannot play this video.

  Please help to sort out my issue.

• ffmpeg : corrupt audio in usage of avfoundation

  3 janvier 2016, par Andy

  I am trying to record my desktop screen (MacBook Pro (Retina, 15-inch, Mid 2014), OSX 10.10.5) with audio. First, I have to find the devices for recording, video:1 and audio:0 in my case.

  User@User-MacBook-Pro:~/test$ ffmpeg -hide_banner -f avfoundation -list_devices true -i ""
  
  [AVFoundation input device @ 0x7ff19a422320] AVFoundation video devices:
  
  [AVFoundation input device @ 0x7ff19a422320] [0] FaceTime HD Camera
  
  [AVFoundation input device @ 0x7ff19a422320] [1] Capture screen 0
  
  [AVFoundation input device @ 0x7ff4b9c22320] [2] Capture screen 1
  
  [AVFoundation input device @ 0x7ff19a422320] AVFoundation audio devices:
  
  [AVFoundation input device @ 0x7ff19a422320] [0] Soundflower (2ch)
  
  [AVFoundation input device @ 0x7ff19a422320] [1] Built-in Microphone
  
  [AVFoundation input device @ 0x7ff19a422320] [2] Soundflower (64ch)
  
  : Input/output error

  Then I run to capture the screen :

  ffmpeg -f avfoundation -i "1:0" out_desktop.mkv

  and the audio of the output stutters terribly.
  But if I use the second external screen (which is connect via HDMI) :

  ffmpeg -f avfoundation -i "2:0" out_ext.mkv

  Then I have no audio problems.

  So, what could be the cause of this behaviour ? Somehow the video device "Capture screen 0" causes the audio stutter.

  Here are the full outputs of the two commands above, Screen 0 :

  EDIT

  The main differences between the two (lengthy) outputs above via

  wdiff -n output1 output2 |colordiff

  is the resolution ([-2880x1800,-] {+2560x1080,+}) and the resulting MB rate ([-(20340000000)-] {+(10880000000)+}). So, what could increase the performance of ffmpeg ?

• Prevent output in error log when ffmpeg job is initiated via PHP's shell_exec()

  19 janvier 2016, par Jake

  I’m getting the entire output of the ffmpeg command printed to my server’s error.log — but as far as I can tell, the jobs complete successfully with no error.

  Is there any way to suppress the output ? I have seen people append stuff like >/dev/null 2>/dev/null & to their command, however that forces the command to return immediately and the job runs in the background. Unfortunately, I need the job to run in the foreground, because I need to do stuff with the output once the job is done.

  Here’s the command I am running...

  shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');

  Here’s the output I am seeing...
