Dlna Client For Mac

Motivation

Looking for a simple DLNA server that I could just fire up in some directory, watch some files on my TV and then be done with it, I came up empty. There are some decent servers out there, like Serviio and friends, but none that fit my requirements. Also there wasn't really a decent enough and uncomplicated enough open source implementation that I could borrow. The Coherence python project seemed to be a good starting point, but was already to complex for what I was trying to achieve. Also, python dealing with Unicode paths on Windows pretty much sucks. Then there is Mono.UPnP, which didn't really work, and the Intel(?) Developer Tools for UPnP, which seemed kinda nice at first, but turned out to be coming straight out of over-engineering hell, in my humble opinion.

And so I decided to write my own server, borrowing some ideas from Coherence, reading some of the UPnP specs and reverse engineering the various protocols involved (yuck, SOAP :p) by watching my TV interact with Coherence and Serviio under Wireshark.

Answered February 12, 2017. VLC does do DLNA and UPnP on OS/X with the newest version 2.2.4 - you have to have your firewall and sharing setup properly. Personally, I use an AnyCast all the time to cast my mac out, and use Plex if I want to cast into OS/X from Windows or Linux. Universal Media Server is a DLNA-compliant UPnP Media Server Universal Media Server supports all major operating systems, with versions for Windows, Linux and Mac OS X. The program streams or transcodes many different media formats with little or no configuration. UMS is powered by MEncoder, FFmpeg, tsMuxeR, AviSynth, MediaInfo and more, which combine to offer support for a wide range of. MiniDLNA is not available for Mac but there are plenty of alternatives that runs on macOS with similar functionality. The most popular Mac alternative is Plex, which is free.If that doesn't suit you, our users have ranked 31 alternatives to MiniDLNA and 17 are available for Mac so hopefully you can find a. Playback is my favorite DLNA Server for MAC OS X, but I just found out that they closed business and are no longer supporting any of their software as of March 2014. I'm using Plex right now as the best of the two others that I've tried; Plex and XBMC (KODI). The Mac running Firestream then sets up a DLNA 'Server' (that's what Firestream is for) and the receiver in the hi-fi system acts as a DLNA 'Client'. Firestream on the Mac looks for the receiver and once it has found it the two parts of the DLNA system (server and client) allows the receiver to play the music from the Mac: Just switch the receiver into DLNA mode and all the music on the Mac suddently appears and is available to play!like magic.

And since I was at it and this is supposed to be an educational and 'fun' project, I decided to do what you shouldn't normally do: Re-invent the wheel by writing my own small http server implementation insead of using the framework one.

Basic use

• sdlna.exe / mono sdlna.exe
  Serve videos from current directory and subdirectories
• sdlna.exe -t image -t audio -v bytitle
  Serve images and audio files from the current directory and subdirectories, organizing files by title.
• sdlna.exe -c cache.sqlite dir1 dir2
  Serve videos from dir1 and dir2 (and subdirectories), storing meta data and thumbnails in the persistent cache store cache.sqlite.
• sdlna.exe --help
  Display usage help.
• SimpleDLNA.exe
  Or just use the WinForms GUI. (This probably won't work too well on non-Windows platforms ;)
• Your front-end here Feel free to contribute something that works better for your preferred platform.

Also, you'll want to have a working ffmpeg binary somewhere within your $PATH, so that video thumbnailing and information gathering works.

Features

• Zero-config DLNA Server without persistent state (optional cache)
• Written in C# (See FAQ)
• Thumbnailing support for images and videos - if ffmpeg is found in the search path -, using any stream as input.
• Meta data as provided by TagLib#
• Serving of any and all file-system addressable files, incl. some views (transformations)
• Should be relatively easy to code up additional media sources, like podcasts

Non-Features, maybe TODO

• Media transcoding
  • Although it should be easy enough to come up with something based on ffmpeg and the various freely available image libraries
• Full DLNA support - only browsing/playing supported at the moment
• Complete SSDP support. Because SSDP makes me cringe, I stopped after getting the basics working
• No Unit testing or test suite... Yeah, laziness is your enemy
• ...

Run requirements

• Some .Net 4 Client Profile compatible implementation to run the app
  • Tested on .Net 4 and Fedora17 + mono, OSX Lion + mono
• File system and networking :p
• Some DLNA renderer (e.g. TV) to actually display the served media.
  • Tested with: Samsung C-Series TV, Kinsky

External dependencies

The external dependencies are nuget managed and can be auto-restored (except for Sqlite maybe... Just reinstall it using nuget into the fsserver project).

Design

The thing wasn't formally designed, but more written as I went along. However, the individual components are only loosely coupled and interact through some real, generic interfaces that allow for extensibility.

Most of the IO is asynchronous, as per .Net Stream.BeginRead/.BeginWrite. No forking (D'OH), no explicit thread management.

The structure is as follows:

• server class library - The actual core that implements an SSDP and HTTP server
  • SSDPServer implementing the important bits of the SSDP-based multicast protocol as used by UPnP/DLNA
  • HttpServer and HttpClient - Custom, stripped down HTTP/1.0 implementation
  • Handlers - Request processing and response composition
  • Responses - Implementing an interface the HttpClient knows how to ship over the net.
  • Views - Transformations of media trees
  • Some interfaces, types, enums, etc. to bring things together
• fsserver class library - Serving stuff from a file sytem. To be 'mounted' by the server
  • Virtual folder/file trees the HTTPServer MediaMount will understand
• thumbs class library - Generating thumbnail pictures from arbriary stream sources
  • Image thumbnailer, using .Net System.Drawing
  • Video thumbnailer, using ffmpeg via async pipes and the .Net Process API
• sdlna CLI application - Bringing the various pieces together
• SimpleDLNA GUI application - Alternative to the CLI and with persistent configuration. This thing is especially rough, as im not an UX guy.
• util Various low-level utility stuff

Feel free to drop me pull requests. If you plan to implement something more than a few lines, then open the pull request early so that there aren't any nasty surprises later. Please try not to introduce too many new FXCop warnings. ;)

If you want to add something that will require some for of persistence incl. persistent configuration or API keys, etc., then open a pull request/issue especially early!

Mini FAQ

• Q: Does it work in my network/with my TV?
• A: At the moment, if you got a somewhat recent Samsung TV, then probably yes. Otherwise probably not. Why don't you just try?
• Q: This thing does not work with my setup?!
• A: Either provide me with the setup (i.e. buy me that TV) or whip out your debugger and Wireshark and read Contributing ;)
• Q: Are you planning to support Podcasts, RTMP streaming, insert name here?
• A: Maybe, but probably not. See Contributing
• Q: Why .Net and C#? I'm on Linux and/or Mac!
• A: Yeah, well... Other languages have their own set of problems. C# is reasonably portable, managed and garbage collected, statically typed and comes with a huge stdlib. And actually quite nice to use. If only it wasn't for Microsoft having invented this stuff and holding various patents...
  Maybe I'll get bored and rewrite this stuff in C++11 or as a Firefox add-on in JavaScript :p

Thanks

To Microsoft, the UPnP(-AV) folks and Samsung and DLNA gurus for designing such a set of specs and protocols, that includes HTTP-alike over multicast UDP sockets, SOAP and XML, dozens of poorly documented namespaces used in SOAP responses, the contentFeatures.dlna.org HTTP header and other fancy tech. Also a big kudos to software engineers for messing up even the most basic things like http header field names are usually case insensitive or the Reason-Phrase of http status lines is purely informal.

Changelog

VLC can easily access media from UPnP (Universal Plug and Play) as well as DLNA (Digital Living Network Alliance). The option is available in the View > Playlist section of the media player. UPnP and DLNA allow you to stream content over your local network. You can see televisions make use of this feature to access videos from your laptops and other devices supporting the standard. It's like sharing the media content that you have on your computer or phone to other devices without the need to copy and move files. All of them should be connected to the same network or Wi-Fi.

If you have VLC on your computer, you will be accessing the files available via UPnP as well as DLNA. There should be another device sharing media files using this standard or protocol. It's like a private network for audio and video files.

Dlna Client For Mac Catalina

Here's how you access media from UPnP or DLNA using VLC:

Mac Upnp Player

• Open up VLC Media Player.
• Go to View > Playlist [CTRL + L].
• On the left under Local Network, click on Universal Plug'n'Play.
• You'll see a list of files or streaming networks listed on the left.
• Browse through them and right click on them to Play, Stream or Add to Playlist.
• You will be playing media from your network in some time.

Mac Os Dlna

Note: It can take some time for VLC to discover and list all the folders and sub-folders from your UPnP and DLNA servers.
