Also known as itag or format codes and way back they could be specified with the fmt parameter (e.g. &fmt=22). Depending on the age and/or popularity of the video, not all formats will be available.

Graphical User Interfaces

For the last few weeks I spend some time coding, writing and cleaning up my notes from almost a year since I published nuklear.

Basically this is a possible implementation for a graphical user interface builder backend with support for an immediate mode style API. So it provides a way to define non-mutating UI state, an immediate mode style API for dynamic UI components (lists,trees,...) and a combination of both.

The core implementation is ~800 LOC without any kind of default widgets or extensions. At first this seems quite counter intuitive. However since the inherent design allows for lots of different ways to define any widget like buttons it does not make sense to provide a specific default implementation. The way this code was architectured furthermore removes the need for style/skinning configurations used in Nuklear since widget painting is just calling a small

1. Copy m3u8 link

2. Run command

echo "Enter m3u8 link:";read link;echo "Enter output filename:";read filename;ffmpeg -i "$link" -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 $filename.mp4

Experimenting with pitch detection and spectral estimators

See the question and discussion on StackOverflow: How to get the fundamental frequency using Harmonic Product Spectrum?.

We’re trying to estimate the fundamental frequency of a voiced A4 note (440 Hz). (See the question for link to audio clip.)

Harmonic product spectrum

Result: full data, 0 to 2 KHz

Spotify has heaps of genres but there not surfaced in the UI. Here's 1383 (perhaps all) of them.
