karaoke | Karaoke built with Web Audio API | Audio Utils library

Detailed: I'm using python to make a small app that scrapes a top 100 song list and creates a spotify playlist from it. I'm bottlenecked by the fact that the spotify API only lets you search by one song at a time (to get its internal spotify ID).

Short: I tried multithreading with mixed results.

For reference, this is what search song does, not entirely relevant:

When doing automated work with ffmpeg/ffprobe, I tend to just select the first stream of video and ignore the rest. Today I bumped into a file where the first video stream has no frames, but the second one does.

Is there a way to reliably know which stream should be selected? I suppose I could look at the number of frames, but I see things like "profile=Main" vs "profile=Baseline", or "level=-99" vs "level=40" and I wonder if those, or some different key, are better indicators.

In the uploading file process, I want to manipulate the content in the memory without saving the file to the disk. For that purpose, I'm using FFmpeg with converting IFormFile into MemoryStream and further on I'm using FFmpeg to change the content and output the result into pipe again for further processing. This whole works fine with the exception that some files cannot be processed.

Again, I'm not dealing with direct files during the process but their memory stream representation.

When I examine 1st file details using ffprobe I'm getting

I'm trying to run a Subprocess in a FastApi route, but the execution results in NotImplementedError. I've read similar questions on the issue:

Why am I getting NotImplementedError with async and await on Windows?

Asyncio.create_subprocess_exec NotImplementedError - Fastapi Background Task

But it doesn't seem they have any viable solutions.

My FastApi route looks like this:

I am wanting to convert a H265 video to H264 with as little to no quality loss possible. However, when converting the output colors are off with most noticeably the reds become orange. In general the output video colors are duller/saturated/grayer.

I believe this question is relevant, so is it possible to add color_range, color_space, color_transfer and color_primaries flags to a file without reencoding the entire thing again?

I have to do a karaoke interface. I need to highlight a part of the text view from time to time. let's say 5 seconds. I have separated the lines by "\n". After 5 sec, I need to highlight the other sent of lines till it meets "\n".

I am attempting to create front-end SPA routing for a client, without a framework, using vanilla JavaScript. Ultimately, I want to click a link in a list element, update the iframe, and update the taskbar URL. However, I can't do any of that until I can use .querySelector() reliably. Below is a snippet with the HTML (which is fine as is) and the JS (which…isn't).

I'm trying to use .setSelfDeaf() in my code but I couldn't figure it out. Every way I tried ended up crashing the bot when executed.

Could someone help me to use it? I want is the bot the deafen itself every time it joins a voice channel.

Edit: added the error I am getting and the updated code upon request.

The error I am getting:

I have a problem with my code, i try to code a discord music bot but i always shows a error message in visual studio code. I tried multiple things but none of them worked. I use distube for the bot because its way more easier.
