  • 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 :

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

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

  • 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.
