    -framerate 60 \
    -s 1366x768 \
    -i :0.0 \
    -f alsa -i default -ac 2 \

  I am using the preset ultrafast because I read that it helps not to compress the video too much.
The output of the recorded test file using ffmpeg is as below.

  The recording works but there is a audio lag. If I record the same using simplescreenrecorder with the same settings like,

  


  audio backend - alsa

  


  source - default

  


  audio codec - vorbis

  


  video codec - h.264

  


  container - matroska

  


  preset - superfast

  It works perfectly without any lag whatsoever. The output of the recorded test file using simplescreenrecorder is as below.

  


   (+) Video --vid=1 (h264 1366x768)
 (+) Audio --aid=1 (vorbis 2ch 48000Hz)
AO: [pulse] 48000Hz stereo 2ch float
VO: [gpu] 1366x768 yuv420p
AV: 00:00:01 / 00:00:17 (7%) A-V:  0.000
[mkv] Discarding potentially broken or useless index.
AV: 00:00:08 / 00:00:17 (47%) A-V:  0.000

Exiting... (Quit)


  


  The only difference that I saw between these two recordings is VO: [gpu] 1366x768 yuv444p
VO: [gpu] 1366x768 yuv420p for ffmpeg and simplescreenrecorder receptively.
I do not know if this matters but is there something that I could tweak to make ffmpeg to capture the screen and audio without any lag.
Like answered here https://unix.stackexchange.com/questions/675436/ffmpeg-recording-slows-down-when-audio-inputs-are-added
I do open pavucontrol but its not much of a help.

  


  The reason that I going with ffmpeg is because I can kill the process using pid at a particular time using cronjobs.
These are my system information, in case if it helps

  Any help is much appreciated.

  


• How to suppress `ffmpeg` output logging when using H.265 codec in quiet mode

  5 avril 2022, par user223364

  When I run :-

  


  ffmpeg -v quiet -i "${INPUT}" -c:v libx265 -crf 23 "${OUTPUT}"


  


  I'm still getting output from the command even though the loglevel is set to silent (see the example of the output below)

  I'm using v5 of ffmpeg

  


  ffmpeg version 5.0-tessus  https://evermeet.cx/ffmpeg/  Copyright (c) 2000-2022 the FFmpeg developers
  built with Apple clang version 11.0.0 (clang-1100.0.33.17)


  


  How do I get ffmpeg to be really quiet ?
