  • ffmpeg failing to expand drawtext

    26 novembre 2015, par charlie80

    I am trying to overlay a seconds:milliseconds timestamp on my video, but I have been breaking my head over this for some hours without any result. If I write :

    ffmpeg -f lavfi -i testsrc=duration=5:size=800x600:rate=30 -vf drawtext="fontfile=C\\:/Windows/Fonts/arial.ttf:text='%{pts}': x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1" -preset ultrafast output.mp4

    the %{pts} does not get expanded, and only shows the literal text {pts} on the frame.

    Please note that I have read a ton of guides around the web (ffmpeg docs/guides/wikis, stackoverflow, blogs, etc.) on this timestamp overlay stuff, but none of the solutions/syntaxes work : it simply overlays the literal text.

    Some context :

    • using Windows 7x64 and TCC/LE
    • ffmpeg Zeranoe build version git-12a419d (2015-11-23)

    The full output log :

    [E:\]ffmpeg -f lavfi -i testsrc=duration=5:size=800x600:rate=30 -vf drawtext="fontfile=C\\:/Windows/Fonts/arial.ttf:text=%{pts}: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1" -preset ultrafast output.mp4

  • 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] [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 killed - not much information for troubleshooting

    26 juin 2022, par Daniel Shen

    can't find out what might be causing this killed. Any tips ? or what kind of logs might help to troubleshoot ? It just says 'KILLED'.

    


    This FFMPEG is installed in my AWS Linux (centos rhel fedora)
I am quite confident the file is OK as the ffmpeg runs ok on my local macos (but different ffmpeg installation from brew).
