• 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.

• How to run a python code via Django templates ?

  18 novembre 2018, par Iskender Berdiev

  I want to execute code below when the is submitted (project on Django) :

  from os import system, listdir, remove
  
  link = 'https://www.youtube.com/watch?v=ME9yO1KEVoo'
  
  
  
  def download(): ## Downloading a video from YouTube using youtube-dl
  
      system("youtube-dl -o download {}".format(link))
  
  
  
  def convert():  ## Converting downloaded video to mp3 format via ffmpeg.exe(same directory)
  
      listOfFiles = listdir('.')
  
      for i in listOfFiles:
  
          if i.startswith("download"):
  
              name = i
  
              system("ffmpeg -i {} download.mp3".format(name))
  
  
  
  def main():
  
      download()
  
      convert()
  
  
  
  main()

  I have tried to put this code into views.py :

  class download(TemplateView):
  
      def main(request):
  
          if request.method == 'POST':
  
              link = 'https://www.youtube.com/watch?v=ME9yO1KEVoo'
  
              system("youtube-dl -o download {}".format(link))
  
              listOfFiles = listdir('.')
  
              for i in listOfFiles:
  
                  if i.startswith("download"):
  
                      name = i
  
                      system("ffmpeg -i {} download.mp3".format(name))
  
          return redirect ('loader/wait.html')

  urls.py :

  path('wait/', views.download.as_view(), name='wait')

  and the html form which is submitted to run views.download.as_view() :

  <form action="{% url " method="POST">{% csrf_token %}
  
  <input type="submit" value="Yes" />
  
  </form>

• Trying to convert an RTSP stream to a HSL file, but get a "Failed to Open Segment" error

  1er juin 2021, par Alvydas Juodikis

  These are the linux commands I ran on ubuntu 20.04 to convert an rtsp stream to a HLS file. I was trying to then display it onto my html webserver to run a live video but I'm stuck at an error.

  


  ffmpeg -fflags nobuffer \&#xA; -rtsp_transport tcp \&#xA; -i <my rtsp="rtsp" url="url"> \&#xA; -vsync 0 \&#xA; -copyts \&#xA; -vcodec copy \&#xA; -movflags frag_keyframe&#x2B;empty_moov \&#xA; -an \&#xA; -hls_flags delete_segments&#x2B;append_list \&#xA; -f segment \&#xA; -segment_list_flags live \&#xA; -segment_time 0.5 \&#xA; -segment_list_size 1 \&#xA; -segment_format mpegts \&#xA; -segment_list Home/Desktop/fmpegsolution/index.m3u8 \&#xA; -segment_list_type m3u8 \&#xA; -segment_list_entry_prefix Home/Desktop/fmpegsolution/ \&#xA; Home/Desktop/fmpegsolution/%3d.ts&#xA;</my>

  


  I'm using an example from this link :
https://girishjoshi.io/post/ffmpeg-rtsp-to-hls/

  


  I try to generate my file into a directory located in my desktop called fmpegsolution (hence the output path Home/Desktop/fmpegsolution)

  


  The error :

  


  When running this on terminal, the error comes out to :
[segment @ 0x558c82e11ec0] Opening 'Home/Desktop/fmpegsolution/000.ts' for writing [segment @ 0x558c82e11ec0] Failed to open segment 'Home/Desktop/fmpegsolution/000.ts' Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

  


  My issue is related to the folder or directory but it definitely exists. I even tried creating a "%3d.ts" blank file (000.ts) but that had no effect. Could use some help. Thanks for your time.
