Hi everyone! First of all sorry for my English.
Like I posted on the Spanish forum (link) I wish to show an QR Code in the skin, when there are a music file playing, with the server's file url to give to the listener the possibility to download to her phone (connected at the same wifi). Is that possible? 
I wait for yours comments

Hi there!

If you're developing the channel, you could put the QR code as a track thumbnail. I can foresee a few issues with it though:

  1. You'll need to generate the code. There's probably some open source library available for it, but you'll have to bundle it with your channel as a shared library and because of it the channel will require elevated sandbox policy.
  2. There's no guarantee that the client will display the QR code in a readable form. Players may truncate thumbnails in order to adjust the view to screen dimensions and there's no way to control that from the channel. If the code is truncated, it'll not read. Also if the player applies any visual effects such as gloss or whatever, it may disrupt the reading as well.

Hi czukoski!
Thanks for your response. I wasn't saw the issue with the truncated thumbnail.
I will analyze the feasibility of this.
 
Thanks again.
