  • 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 @ 0x7ff4b9c22320] [2] Capture screen 1

[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 ?

  • FFMPEG crop video output is black screen, sound is good [on hold]

    11 janvier 2016, par Oum Alaa

    I cropped a video using ffmpeg command line, the output is black screen, the sound is clear and good :

    ffmpeg -i Original.mp4 -t 00:00:29 -vf "crop=634:300:0:60" Done.mp4

    ffmpeg version :
