![]() We pre-cache upcoming tracks (configurable up to 40) for the same reason.We cache current and next track to minimize buffering and speed up track skipping.We use the OPUS codec for the highest quality audio at low bitrates for fast startup on mobile.This sounds simplistic, but it informed a lot of decisions: For Plexamp v3, it came down to: play music fast, don’t stop. (Want to check it out for yourself? I highly recommend Expo, which is essentially a layer on top of React Native which makes the entire process from start to shipping much easier in many cases.) PhilosophyĪpplications should have a raison d’être. If this isn’t developer nirvana, I’m not sure what is. Thus, a single codebase can target 5 platforms (Android, iOS, macOS, Windows and Linux) with only tiny amounts of per-platform code. We also made use of react-native-web, which extends the portability to desktop through Electron. The TREBLE player has been shipping in our official applications for quite some time now, and we’ve been continuing to improve functionality, reliability and performance.Īs for the app itself, over the last year of nights and weekends, we’ve completely rewritten Plexamp using React Native, which is the most mature, productive and performant way to build cross-platform mobile apps for iOS and Android (sorry Flutter, although I think you’ve come a long way). It’s the future of audio playback across all Plex applications which can host it. We’ve also implemented a few effects plugins on top for spoken word audio: one for voice boosting, and the other for silence compression. It’s portable across almost all desktop and mobile platforms, and provides the features you might hope for: sample-accurate gapless playback, high quality resampling, Sweet Fades, soft transitions, pre-caching. Over the next two years, we worked to overcome both of those limitations.įirst, we set out to create a new audio player library we call TREBLE, built on top of a low-level commercial audio engine. The app itself was built in React, which is tied to the web. It incorporated an advanced player under the hood which provided features like gapless and crossfading and it drove a number of improvements to the Plex Media Server for music libraries, including advanced loudness analysis and library and artist radio.Īt its core, though, it suffered from a number of inadequacies which limited its potential: the player engine had portability and licensing issues beyond desktop platforms and didn’t have an easy way to add functionality (effects plugins, e.g.). The first version of Plexamp was a small, highly opinionated music player released for macOS, Windows and Linux. * We’ve benefited from all the work the amazing Expo team has done on the ecosystem, but since we started over a year ago (notably, before Expo launched web support ) and because we have a number of native components, we’re on what’s essentially the Bare workflow. We’ve just launched two apps written entirely in React Native with Expo: Plexamp (a beautiful Plex music player, available on five platforms) and Plex Dash (a Plex Media Server admin app on iOS and Android). □ from Plex Labs, a part of Plex which focuses on passion projects and R & D. ![]() He originally posted about both Plexamp and Plex Dash on the Plex Labs blog. We asked Elan Feingold to share a little more about Plexamp, one of two multi-platform applications he and his team launched last week. This is not a setup that applies to most users.Plexamp v3: the road to React Native bliss This includes those hosted in a data center as well as machines on a “local network” that have been put into the “DMZ” (the “de-militarized zone”) of the network router. Warning!: For security, we very strongly recommend that you do not allow any of these “additional” ports through the firewall or to be forwarded in your router, in cases specifically where your Plex Media Server is running on a machine with a public/WAN IP address. TCP: 32469 (access to the Plex DLNA Server).TCP: 8324 (controlling Plex for Roku via Plex Companion).UDP: 5353 (older Bonjour/Avahi network discovery).UDP: 1900 (access to the Plex DLNA Server).The following additional ports are also used within the local network for different services: TCP: 32400 (access to the Plex Media Server).The most important port to make sure your firewall allows is the main TCP port the Plex Media Server uses for communication: This is not discussing ports on a router. Note: This article is discussing ports in the local firewall of the computer running Plex Media Server.
