  Merge "Code cleanup."

• Capture video with pulse audio on a second camera with motioneye [closed]

  8 mai 2023, par Damien JALLON

  On a raspberrypi 4, bullseye os, motioneye service capture motion with camera on /dev/video0 and launch this script that capture video with pulse audio on a second camera on /dev/video2 :

  


  echo $USER >> /home/damien/motion_ffmpeg.log
cd /home/damien
source /home/damien/.profile
source /home/damien/.bashrc
file="/home/damien/Vidéos/motionEye/motionEye_$(date +%Y%m%d_%H%M%S).mp4" # Création d'un nom de fichier horodaté
/usr/bin/ffmpeg -f pulse -thread_queue_size 4096 -ac 1 -channel_layout mono -i default -f v4l2 -thread_queue_size 4096 -i /dev/video2 -t 00:00:03 -vcodec mpeg4 $file >> /home/damien/motion_ffmpeg.log  2>&1 < /dev/null & 


  


  The script work perfectly in standalone, in a terminal connected with the user "damien".
The log produce in standalone :

  The message "default : No such process" seems to mean that there is no connection with the pulse server.

  


  Why does ffmpeg not connect to pulse server when launched by motioneye ?

  


• Errors in compiling FFmpeg for windows10/aarch64 using Microsoft Visual Studio 2017 Preview edition

  29 octobre 2018, par Narsinga

  I am trying to compile FFmpeg (the Chromium version) for Windows10/Aarch64 configuration using Microsoft Visual Studio 2017 Preview community edition. I am running into errors in the assembly files as copied below (highlighted few errors). I believe FFmpeg is working for Linux/Aarch64 configuration (probably using GNU assembler) already in which case the same assembly code should also work for Microsoft ARM Macro Assembler as well. Please let me know if I am missing anything here and any pointers to help resolve the errors.
