## Bugs
|
||||
|
||||
This project is a result of bodging and therefore has tons of bugs which need to be ironed out
|
||||
|
||||
## To-Do
|
||||
|
||||
[ ] Move away from using os.system calls, and use Python modules instead ( Looking at you, Sox and aubio)
|
||||
[ ] Clean the Code
|
||||
[ ] Add Artwork Generator
|
||||
[ ] Add Video Generator
|
||||
[] Move away from using os.system calls, and use Python modules instead ( Looking at you, Sox and aubio)
|
||||
[] Clean the Code
|
||||
[] Add Artwork Generator
|
||||
[x] VHS Picture Styler ( Added in v1.5 )
|
||||
[] Add Video Generator
|
||||
[] Add Custom Date to VHS Styler
|
||||
|
||||
## Credits
|
||||
|
||||
@WJLiddy His repo `Macintech` forms the base code for the music generator
|
||||
|
||||
@felipecustodio Using his repo `virtualdreamsbot` YouTube DL code ( Hopefully I will be able to integrate this project as a Telegram Bot)
|
||||
|
||||
@Ragex04 His repo `VHS_BingImages` forms the base code for the VHS Image Styler
