  hw_base_encode : refactor picture allocation/freeing
  This commit cleans up and refactors the mess of private state upon
  
  private state that used to be.
  Now, FFHWBaseEncodePicture is fully initialized upon call-time,
  
  and, most importantly, this lets APIs which require initialization
  
  data for frames (VkImageViews) to initialize this for both the
  
  input image, and the reconstruction (DPB) image.

• Understanding User Flow : Eight Practical Examples for Better UX

  4 octobre 2024, par Daniel Crough — Analytics Tips, UX

  Imagine trying to cook a complex dish without a recipe. You might have all the ingredients, but without a clear sequence of steps, you’re likely to end up with a mess rather than a masterpiece. Similarly, designing a website without understanding user flow is a recipe for confusion and lost conversions.

  User flows—the paths visitors take through your site—are the recipes for digital success. They provide a clear sequence of steps that guide users towards their goals, whether that’s making a purchase, signing up for a newsletter, or finding information. By understanding and optimising these flows, you can create a website that’s not just functional, but delightfully intuitive.

  In this article, we’ll explore seven practical user flow examples and show you how to apply these insights using web analytics tools. Whether you’re new to user experience (UX) design or a seasoned professional, you’ll find valuable takeaways to enhance your digital strategy.

• mpv player with SFTP does not work in bash script [closed]

  19 mars 2024, par Pickles888

  I am making a bash script to make it easier to stream from my media server at home.

  


  In the bash script, it asks whether you want to list or search, and then uses mpv to stream the file. For some reason it says the file does not exist. When I try this in the terminal it works, but running the script gives this error :

  


  [ffmpeg] libssh: Error opening sftp file: SFTP server: No such file
Failed to open sftp://[username:password]@[ip.of.server]/[directory/to/file]


  


  My script :

  


  #!/bin/bash

pass="[password]"

if [ $(nmcli | grep -c [home-network]) -gt 0 ]; then
    ip="[private.ip]"
else
    ip="[public.ip]"

  Anything put in brackets is to not share my personal info (except for arrays, if statements etc)

  


  Also this seems to have only changed while I was making the script. In the beginning, it was working great, but at one point it randomly stopped working.

  


  I have a feeling its some kind of quote mess up or something stupid like that. I have tried to edit it and fix it to the best of my abilities but nothing I did fixed it.

  


  I also think it could have to do with it being run in the bash environment as I normally use zsh. However I tested it in my shell by running /bin/bash and executing the command and it worked.

  


  Also the option chooser was not made by me.
