After I could not make a reserve at a commercial karaoke with my friends, I made a party at home using a very simple Python/Kivy program to add URLs of karaoke videos from Youtube, download it, put in a playlist and play automatically in a TV connected do my notebook. I had time and energy to make it from a very small hobby project to a not-so-small-I-spend-too-much-time-on-this-help-me, resulting in this shit -- I mean, this beautifully constructed Python program.
If you don't want to download youtube videos, this program is not for you. You may just add your videos to a youtube playlist. But, if you want to save them in your PC, or use videos from other websites that do not support playlist (refer to youtube-dl repository to see a list of supported websites), this may be for you.
- Downloads video from Youtube (or any youtube-dl supported site), saves in a folder and puts in a playlist
- Uses VLC as player
- Simple csv database where the metadatas from videos are stored
- Integrated database search
This code was written in Python 3.6.4, using Kivy 1.10.0, in a Windows 10 64-bit machine. I can not guarantee that this program will work even in such configuration. Freely make the necessary adaptations to run in your machine if you want.
This software needs the following external Python modules:
- Kivy
- youtube-dl
- vlc
Because I don't know how to carry this imports around, you should download it manually. Make sure to have your Python installation in PATH in your Windows. Open the command prompt and type:
py -m pip install kivypy -m pip install youtube-dlpy -m pip install vlc
Change the global variable VLC_PATH to the folder where the vlc.exe is installed. Remember to use double backslashes (\\) if you are in Windows. Moreover, I recommend you to change the global variable WAIT_TO_NEXT_SONG to a value that fit your desires. Both variables are inside karaopy_guts.py.
Double-click on KaraoPy.py or via command prompt, cd to the installation folder and type py KaraoPy.py.
- Kivy
- No support for search using IME (eg. Japanese characters), due limitation of... Kivy. I discovered a not perfect workaround, but I have not implemented yet
- High CPU usage (~80% in my Core i5 2nd generation)
- High memory usage
- No support for different resolutions or pixels density besides my own screen
- Non-ocidental and non-CJK characters may will render as squares
- The current time on screen sometimes goes slightly fast or slightly slow, but you need to concentrate on it to realize
- Me
- Have I already said Kivy?
Yes. Every time the program executes, it checks the folder for new (or deleted) files and update the database accordingly.
Yes, read question above.
Open the karaoke_database.csv, located in the folder you have put your KaraoPy.py. The fields are separated by a (not commom) vertical bar (|). Change the respective title and artist field for each entry. If you need to write the metadata with vertical bar, put the contents of that field around double quotes ("This | is a example"). Do not change the others fields! Do not modify while the program is running!
Because Kivy. I searched a lot for a solution with no avail. If I use threads, then user interface become very, VERY laggy. I had to live with it.
Good question, I would like to know too. If you know how to solve, please, tell me.
Because it is Hue lang-I mean, Portuguese. You can change that messages if you want. Almost all the variables in code are self-explanatory (this_explain_why_I_use_a_lot_of_underscores).
Is it even a question?
Yes, send me a message.
Do I hate it? Ok... I'm not a professional coder, I just do it by hobby, but I think that while Kivy made this program happen, the documentation is not good (one of main features, the KvLang, is largely ignored by documentation. I learned a lot about the language through Google searching); the explanation of the API lacks a "how to use"; you just can't type IME on a Kivy text input field; you need workaround for Kivy to work with threads; there is no fallback font when glyphs are not found in used font (e.g. Arial does not have Japanese glyphs. Word uses a fallback font which have; Kivy display squares), etc. I survived, but I've lost an arm and a leg while transmutating Kivy into my software. On other side, I just love Python! Easy, beautiful, a lot of modules and great documentation.
Wait, your program looks like a media player. Why don't I use VLC directly, manually putting videos on playlist?
Yes, you can. But wouldn't be fun for me to write it!
Surely.
Besides the imports, fonts (Noto Sans, from Google), and small snippets from Python documentation and modified version of the hash method (based on imohash), everything else was made by me, including logos and buttons designs. I have not choose yet which license, so I retain full copyright, but surely you can read, download, modify (fork), redistribute, make a executable and have fun, in a non-commercial way, and giving credits to me (link to the repository page on GitHub and my name), and your modification (forking) or executable should have the same condition. And also the classic don't blame on me if your computer explodes. You use at your own risk!
