adding media_player_mpy to OpenSesame

Comments

  Update: i realised I was missing a 'plugins' folder in that directory. I added the media_player_mpy folder to the newly created plugins folder. And now I have the media player module! However...

  When I add the module to an experiment I get an error (pasted in full below) that seems to be a problem of the mediacoder.

  So I found where to download the mediacoder from githubg:

  https://github.com/open-cogsci/opensesame-plugin-media_player_mpy

  But where do I put this (and which files/folders do i need)?

  
  

  Full error message I mentioned above:

  Hi,

  Try installing the missing package(s). In the case of mediadecoder, https://pypi.org/project/mediadecoder/

  Hope this helps,

  many thanks for the reply @eduard

  I'm afraid i'm a novice with python. I can't tell which of those to download (source distribution, or one of the two Built Distribution options?).

  I went a head and downloaded Built Distribution for py3. It appears I need to use python to install this?

  Although I found this guide for installing (https://packaging.python.org/en/latest/tutorials/installing-packages/), but I've found it fairly impenetrable. Hoping installing this is not too difficult. My previous version of OpenSesame did not require this.

  Generally, you can use following procedure.

  1. Identify the missing package based on the error message (Usually the part "ModuleNotFoundError: No module named <MODULENAME>" gives it away
  2. Look online how this package is installed (that will give you a pip install like the one I linked above, in most cases)
  3. Install it directly in Opensesame, via the debug window (see here for guidance). If I am not mistaken, the syntax is simply !pip install MODULENAMEOptionally with a --user flag (in case you don't have root write permissions)

  I hope this helps!

  ok great, point 3 helped a lot as I had no idea this step was needed. I was actually already working on step 2 but was stuck, but have worked it out. :)
