zune-image VS Symphonia

Thanks to the zune-image library, serde-numpy is now supporting PNG and JPEG. Enabling faster io for neural net training loops and other image processing in python

It has been extensively tested on 600,000 real world images, as well as fuzzed in various ways, and is now ready for production use!

I might have misunderstood what you've written, but is there a reason you can't use https://github.com/etemesi254/zune-image as a JPEG decoder? It has minimal use of unsafe and is performant.

It uses SIMD for colorspace conversion and IDCT, the code can be found here and here.

You can see a Github Action that zune-inflate uses here, it's mostly self-explanatory.

I've just added a roundtrip fuzzer to the Rust translation of it so that we can start weeding out the bugs: https://github.com/etemesi254/zune-image/pull/13 Right now it finds some decoding failures in a few seconds.

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.
