• avcodec/codec_internal : Add macro to set AVCodec.long_name

  29 août 2022, par Andreas Rheinhardt

  avcodec/codec_internal : Add macro to set AVCodec.long_name
  It reduces typing : Before this patch, there were 105 codecs
  
  whose long_name-definition exceeded the 80 char line length
  
  limit. Now there are only nine of them.

• avcodec/internal : Move ff_get_buffer() to decode.h

  24 août 2022, par Andreas Rheinhardt

  avcodec/internal : Move ff_get_buffer() to decode.h
  Only used by decoders (encoders have ff_encode_alloc_frame()).
  Also clean up the other headers a bit while removing now redundant
  
  internal.h inclusions.

• How to fix laggy ffmpeg screen and audio capture ?

  26 juillet 2022, par Wh0r00t

  I am using ffmpeg to capture the screen along with audio.

  


  The ffmpeg command that i tried is

  


  ffmpeg -y \
    -f x11grab \
    -framerate 60 \
    -s 1366x768 \
    -i :0.0 \
    -f alsa -i default -ac 2 \
    -r 30 \
    -c:v h264 -crf 0 -preset ultrafast -c:a vorbis -strict experimental  \
    "$HOME/Videos/$fname-$(date '+%y%m%d-%H%M-%S').mkv"

  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.
