GeneralUtils.deleteFileUtil(strAudioFolderPath + "vk.log");
PowerManager powerManager = (PowerManager) this.getSystemService(Activity.POWER_SERVICE);
PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "VK_LOCK");
wakeLock.acquire();
LoadJNI vk = new LoadJNI();
try {
try {
vk.run(GeneralUtils.utilConvertToComplex(s), strAudioFolderPath, MainActivity.this);
Log.e("Checking water marker", ">>>>>>>>>>>>>>>");
} catch (Throwable e) {
} finally {
if (wakeLock.isHeld())
wakeLock.release();

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

Raspberry Pi Camera feedback freezes when moving NEMA 17 stepper motor with A4988 stepper motor driver [closed]
31 août 2023, par Broteen DasI 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 ?
