![]() Depends on the precision, you might want to run the query multiple times a second. Either way it is, it already sounds a lot complicated and resource-consuming, in a worse case, some may even need to send a request through the internet for the playing progress. Usually to query the progress, you had to go through some kind of RPC, or running a tiny script. In contrary, it is almost never the case in real life. The second way, query the player for progress on a regular time interval, could indeed solve the problems mentioned above, but just in an ideal system where the query itself is as simple as reading a variable. Even worse some might just lack of such feature exposed to the public, rendering this way unusable in those cases. In the worst case, some lines might just be skipped over due to the long update interval. Some platforms may issue updates several times a second, but some may just send once a couple of seconds. The first way, relying on the player to send out progress update events, is not reliable because the update interval totally depends on the platform. Both ways are not ideal when it comes to the extreme cases where the user adjusts the player progress a lot, and the lyrics having a lot of lines in a short period of time. In short, there are 2 major ways of doing it: rely on the player to send out update events, or query the player for progress at a regular time interval. Common practicesīefore we go to LyricsX, let’s first take a look at how the majority of other open source software work on this. Here in this article, I’d share with you how LyricsX tracking the player progress in a unique and resource-saving way. It gets time-tagged lyrics files from local storage or internet, and then display the lyrics in sync with the player.Īs a crucial component of the development of Lyricova Jukebox, I have researched multiple implementations of real time lyrics display programs, and I found the mechanism behind LyricsX particularly interesting. > db.metadatas.get('swinsian').LyricsX is an open source software for macOS to download and display lyrics of current playing track on Music (previously iTunes), Spotify, Audirvana, Vox, Swinsian, or the Now Playing indicator in the OS. This all started trying to get a new-in-python-3.11 method out of string.Template, and now I'm so far down the rabbit hole I can no longer see the sun.Īnyone have any ideas? > db.metadatas.get('swinsian') I messed around with the path just to see if I could get anywhere, but the app seems clear on working vs broken paths.į-SA knows the the database info too, there's just something Wrong and I'm out of steam. I did come across this question which seems related, except my sqlite connection is defined with an absolute, not relative path. ![]() I've been reading through the release notes for Flask-SQLAlchemy 3.0 and I have yet to find anything that suggests the source of the problem. All the same code works fine in the main not-yet-upgraded code environment. The error: : (sqlite3.OperationalError) no such table: playlist Since upgrading to 3.0.3, Flask-SQLAlchemy gives an error whenever I try and query any of the databases in SQLALCHEMY_BINDS, but the main database is working fine. I've got a Flask app with multiple SQLALCHEMY_BINDS. ![]()
