• 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

• Video recording solution for angular and spring boot app [closed]

  24 juin 2022, par Shinu Mathew

  I am trying to build an app with angular on the front end which should be able to record video using users webcam and send data to a spring boot backend microservice in parts. I have tried using client libraries like video-recordjs but I face a lot of issues when it comes to cross platform and devices. I am looking for a reliable solution which would help me to accomplish this and work well on all browsers and devices. Any suggestion or help would really be appreciated.
