• FFMPEG image capture only executes partially on cron

  17 mai 2022, par C. Ardayfio

  I have the following shell script :

  


  DailyScript.sh

  


  #!/bin/sh
now="/Users/mydir/Downloads/LIDOPRO/Captures/$(date +'%Y_%m_%d_%I_%M_%p').jpg"
"/Users/mydir/Downloads/LIDOPRO/ffmpeg" -ss 0.5 -f avfoundation -framerate 30 -i "0" -frames:v 1 -t 1 "$now"


  


  It produces an image through my FaceTime camera when I run the script manually in shell, as follows :

  


  $ /Users/mydir/Downloads/LIDOPRO/DailyScript.sh


  


  And the output I get is the following

  Everything works perfectly fine and the image is output.

  


  So, I created a cron job to run the script automatically, as follows :

  


  * * * * * /Users/caineardayfio/Downloads/LIDOPRO/DailyScript.sh 2> /tmp/error.txt 1> /tmp/output.txt


  


  However, this cronjob does not actually work. No photo is produced and the script seems to execute, but only partially :

  output.txt is empty

  


  Does anyone know how to resolve this issue ? I'd like the image to be produced.

  


• FFmpeg 5 : How to add cover art to m4a file

  17 mai 2022, par dch09

  I've tried

  


  ffmpeg -i input.m4a -i image.jpg -map 0 -map 1 -c copy -disposition:v:1 attached_pic output.m4a 


  


  from this answer FFmpeg, how to embed cover art (image) to .m4a

  


  but that does not seem to work correctly, giving me output as below :

• lavc/riscv : depend on RVB and simplify accordingly

  lavc/riscv : depend on RVB and simplify accordingly
  There is no known (real) hardware with V and without the complete B
  
  extension. B was indeed required in the RISC-V application profile from
  
  2022, earlier than V. There should not be any relevant hardware in the
  
  future either.
  In practice, different R-V Vector optimisations in FFmpeg already depend on
  
  every constituent of the B extension anyhow, so it would not work well.
