toydb VS Symphonia

This is great, but you might want to consider a different name. There's already a Rust project called ToyDB, and it's a distributed database with a Raft log, SQL, disk persistence, ACID transactions, etc. It's under active development (though the developer now works at Cockroach Labs), and has 5K stars on GitHub, so I think they have the right to the name.

Build something you’d like to learn about. Things I’ve considered replicating: A distributed database (see https://github.com/erikgrinaker/toydb), an interpreter (crafting interpreters is a good book), a Ray tracer (http://raytracerchallenge.com/), an RPC compiler and framework, a simpler neural network framework ( https://github.com/pjreddie/darknet)…

Hilariously, I was trying out ToyDB on the Lichee-RV recently. While it does compile and run the five-node example setup (and memory usage is surprisingly low, which is a plus considering the 0.5GB of RAM), performance is three orders of magnitude lower than on a desktop x86 PC. Some of that is due to just having a single core run 5 nodes, some is due to the lower clock speed and slower memory, and some is due to slower storage (SD card). I don't think that explains everything, so I may investigate that later.

Well I think if you could replicate this https://github.com/erikgrinaker/toydb anybody would hire you.

Symphonia for an amazing audio library

Are you trying to play audio from something like an internet radio station where the stream has an infinite length? The content length header is optional. It uses that to support seeking within the file. Symphonia, one of the underlying backends for Rodio, has an option to tell the decoder that the source is not seekable if the size of the file is not known. Unfortunately, Rodio currently hardcodes this setting to true https://github.com/RustAudio/rodio/blob/master/src/decoder/read_seek_source.rs#L19. I actually wrote this code a few years ago so I should know this, but I can't remember why exactly. I think there was no easy way to communicate this information to Rodio since the other backends don't have a setting like this. The other Rodio backends may handle this differently. There's a lot of great info in this discussion on the Symphonia repo about this use case which helped me with my implementation: https://github.com/pdeljanov/Symphonia/discussions/153

Everything I can find on the internet seems to be abandoned. Opus-rs, Magnum, Magnum Opus, ect. Symphonia has been working on it for over 2 years, with work still ongoing. Heck, even FFMPEG seems to not have full support yet!. Is there any library that I have overlooked that provides this functionality?

In other areas, miniz_oxide is faster than miniz, Symphonia is faster than ffmpeg on most codecs, the not-yet-announced zune-png beats both libpng and the more heavily optimized libspng, and the png crate is getting considerable improvements too and also beats libpng.

Symphonia is an audio decoder framework in 100% safe Rust supporting the most popular media formats (MP4/M4A, OGG, MKV/WebM, WAV) and audio codecs (AAC-LC, ADPCM, ALAC, FLAC, MP1/2/3, Vorbis, PCM).

The Music Player is based on Rodio, which is a high-performance audio playback library for Rust, and Symphonia, which is a Rust library for working with music metadata and audio decoding. This allows the Music Player to provide high-quality audio playback and management.

You can look at symphonia for a pure Rust solution.
