  • Animation with gnuplot : only one cruve plotted in an animation whereas 2 expected

    26 mai 2022, par stefan

    I have the following script which is expected to produce the animations of 2 curves :

    


    #!/bin/bash

for i in {1..397}; do
gnuplot -p <<-EOFMarker
set terminal png;
set output "pic$i.png";
set title "power spectrum";
set xlabel "scale (k)";
set ylabel "P(k)";
set key top left;
set grid;
set ytics out nomirror;
set xtics out nomirror;
set logscale x;
set logscale y;
set format x "10^{%L}";
set yrange [0:30000];
plot "CAMB-1.3.5/matter_camb$i" u 1:2 w l;
replot "EFTCAMB_v3_beta/matter_eftcamb$i" u 1:2 w l;
EOFMarker
done

# Build movie with ffmpeg
ffmpeg -start_number 1 -i pic%d.png  movie.mpeg


    


    Every works fine excepted the fact that only one curve is plotted in animation (CAMB-1.3.5) :

    


    Here is an example of frame :

    


    enter image description here

    


    Why the "replot" command is not taken into account in the generated image ?

    


  • Raspberry Pi Camera feedback freezes when moving NEMA 17 stepper motor with A4988 stepper motor driver [closed]

    31 août 2023, par Broteen Das

    I have a Raspberry Pi with a camera module and a NEMA 17 stepper motor connected to it. When I run the command ffplay /dev/video0, the video runs perfectly. However, whilst the video is running, and I run a script that moves the Stepper motor with the A4988 stepper motor driver, the video feed freezes and needs to be restarted.

    


    At first I thought it was ffmpeg's fault, so I tried viewing the feed with OpenCV, but the same probelem persisted.

    


    I also thought that the CPU prioritization was causing the problem, but this one time, the entire Raspberry Pi froze. The Keyboard, mouse, keys, numlock key, everything was dead (the Numlock light on my keyboard was on, I tried toggling the NumLock, but it did not go off) and so I had to turn off and turn on again the power supply to reboot the Pi.

    


    How do I get rid of this issue ?

    


  • vulkan/common : Use u32vec2 buffer type instead of u64

    27 novembre 2024, par IndecisiveTurtle
    vulkan/common : Use u32vec2 buffer type instead of u64

    According to the GL_EXT_buffer_reference spec alignment
    
"must be a power of two and be greater than or equal to the largest scalar/component type in the block."
    

    This means by using u32vec2 we can drop the requirement alignment from 8 bytes to 4 bytes
    
and save a pack64 call in reverse8 (though I assume in most ISAs that compiles to nothing)
    

    Allows the vc2 vulkan encoder to function without setting PB_UNALIGNED
