Standard version: Allows consumers to share media by enabling consumer electronics (CE) manufacturers to integrate Digital Media Server (DMS) and Mobile Digital Media Server (M-DMS) capabilities into their devices for non-DRM protected audio, video and photo media types to supported devices. It is available as a standalone server (end user installable) or an embedded server.
It should be noted that the EX2 Ultra is a different device than the single bay My Cloud (the general subject of this subforum). As such what works on a single bay My Cloud to fix certain Twonky issues may not apply to multi bay My Cloud models like the EX2 Ultra. As for Plex, the single bay/single drive My Cloud does not officially support running the Plex Media Server. It can serve as media storage library for a Plex Media Server running on another device. If Plex has to transcode the media (like MPEG2) for the client device to play it, it will fail as Transcoding is not supported on most of the My Cloud devices that support the Plex Media Server. The solution is to re-encode the media into a format that the client device can support (like MP4 or MKV for example).
See specific DLNA media device user manuals for instructions on connecting a DLNA device to your local area network so you can access content on the My Cloud device. Go to for a list of DLNA-certified devices and for further information.
Expand the Media Receiver section on that same page (indicated in the screen capture) where you can review the media receivers that Twonky thinks your DLNA clients are using. Its possible it has selected the wrong Media Receiver for your TV (or the problematic device). If mismatched, one can change the media reciver to more closely match the playback device.
Q. What is a Media Server?
A: A Media Server is a piece of software that looks for media files on a disk, or network, and creates a catalogue, or database, of the files it finds. The server uses the file type and metadata embedded in the file to create the database. Client applications can then interrogate this database, and request the server to send the file to them, or to a media renderer for playback. This combination of file store, database and server is often called a media library.
The Media Server on the MyCloud is called Twonky, and uses the DLNA and UPnP protocols to talk to client applications and renderers.
Q. Where should I put my media so Twonky finds it?
A: By default, when MyCloud starts Twonky (when you turn on Media Streaming), it tells it to look for all types of media (music, photos & videos) in all folders in the Public share. If you use the Twonky UI, and go to the Sharing page, you will see just one line:
You can change the folders and media types to suit your requirements, by using the Browse button to select the folder, and the drop-down menu to select file types. For instance, I use the following settings to serve media from my private Media share:
If you want allow people to see your media library within your local network, but not allow them to modify it, you can also create a private share, and put your media in it. Enable media serving on the private share, using SharesShare ProfileMedia Serving
Another common reason seems to be that, following a MyCloud restart or firmware upgrade, it comes back with the SharesPublicMedia Serving turned off. This seems to manifest itself as Twonky scanning the directories, and finding lots of media (viewed using the SettingsStatus page of the Twonky UI), but, when it finishes the scan, it seems to suddenly realise that Media Serving is turned off, and goes and deletes all the entries from its database, and the media counts fall back to zero, [or near zero]. The default state of the MyCloud is confused; Media Serving defaults to OFF:
Q. Can I stop Twonky searching in certain folders in my media storage folders?
A: Yes, you can do this by adding the name of the folder to the list of ignored directions, using the SettingsAdvancedIgnore Directories control in the Twonky UI. The list is simply a set of comma-separated strings.
If you need to make your music library available to visitors who cannot be trusted, create a private share and put all your media under that, then enable media serving on that share, and get Twonky to search for media in that private share. DLNA ignores access control, so DLNA clients will be able to see the media on your private share, but visitors will not have access to your private share via network file access.
[However, if you feel that secured access to the Twonky UI is necessary, then I would suggest that you disable the Twonky server using the SettingsMediaMedia Streaming control, then SSH login as root, and start Twonky using the command:
Q. Why does my media player not show the right track information?
A: A media server looks at the metadata stored in the file, as well as the path and filename. There can be all sorts of metadata tags within a file (Artist, Album Artist, Album, Track Title, Publish Date, Composer, etc, etc), and a media server will fetch these and provide some or all of them to media client applications.
I prefer to do it the easy way though. You have 2 mac addresses for the WD MyCloud. 1 under the device itself and another for the other devices where the twonky server sits as an unknown device on windows 8.1. Block the unknown device mac through the modem/router and when you double click on your WDMyCloud via windows explorer to access network shares, it will log you into the twonky GUI with a nice user friendly interface.
Interesting that I noticed this, too, last night with my DL2100. I have an app on my Kindle tablet called Avia, and it did not see my newest mp4 additions, although the WD My Cloud app had no problem. Rescan media did not help, but Rebuild the media DB did. Indicating to me that the Avia app reads the NAS differently than the My Cloud app, and Rebuild helped the Avia app get back in step! Weird.
rodmichael, That is one thing that I really like about Plex as it does all the encoding for your flawlessly. This is the main reaason why everyone in my household (7 people) all use Plex over any other media streaming method.
TwonkyMedia server (TMS) is DLNA-compliant[1] UPnP AV server software originally offered by TwonkyVision GmbH. TMS runs on Linux, macOS, Microsoft Windows, iOS, Android and QNX operating systems. TwonkyMedia server can be used to share and stream media to most UPnP AV or DLNA-compliant clients, in addition to non-UPnP devices through the HTML, RSS, and JSON supported front ends. After the PacketVideo acquisition of Berlin-based TwonkyVision GmbH by 17 October 2006,[2] Twonky was renamed PVConnect in November 2007,[3][4][5] but the name was changed back to TwonkyMedia server by 7 January 2010.[6][7][8] Corporate parent NTT DOCOMO sold PacketVideo NorthAmerica and Europe to Lynx Technology on 10 May 2015 and PacketVideo Japan exactly one year later on 10 May 2016 transferring the Twonky product line to Lynx, renaming TwonkyMedia Server to Twonky Server.[9][10][11]
I would really appreciate if Buffalo could care about this topic !!! It is really ugly if user must repair linkstation firmware in order to get a linkstation with working twonky media server!!
I have a QNAP NAS TS 209 SII running a Twonky media server (Version 6). I've password protected the web server where the Administration's page is exposed. I Have also a Twonky media server running at the port 9000 which uses its own web server and NOT the apache one.
I agree. My past experience with transcoding has been bad. I tried twonky in the past running under WinXP Quad core and the clients struggled to stream the movies because the server could not keep up...and these were only DVD VOB files..i.e. Standard Definition. So for me Trancoding is a non-flyer on my HP-N40L microserver which has low-spec AMD dual-cores. There's no way they can transcode HD on the fly AND stream simultaneously. May be the new s/w is a bit more efficient...may try it.
Please also keep in mind that above manual prepared for x86 architecture as my system runs on OMV 2.2.5 i386 due to lack of powerful hardware. So if need x64 architecture, please download media server and library file in first step accordingly.
Glad to hear, that's what I've found reading on the topic. A few screenshots from the twonky server interface. IP's blocked, but the twonky server sees the control 4 ea1 control via its mac and ip address. What else could I share that would be helpful?
Sorry, I can't offer anything. I do use a DLNA server (Serviio), but don't run it on a NAS. Odds are if the Twonky channel was removed from the Channel Store, then Twonky has decided to stop supporting it.
I have no idea if there's any other DLNA server product that can be run from a WDMyCloud NAS device. Serviio has versions for QNAP and Synology, but I have no idea if either might work on your device.
I am also having trouble with the Twonky app on a WD Ex2 with OS5. After installing the app from the WD app store and selecting my Roku device the app prompted me to install the Twonky channel on the Roku, the Roku responded and installed the channel, all my content in the shared folders I set up is available on the Twonky app via my computer but when I click on the Twonky Channel on my Roku I get the message: Channel not available: twonky is no longer available, you may want to remove the channel from the home screen.
The Twonky app itself is in fact no longer supported on the roku. You have to configure the app on the WdMycloud ex2. I can walk you through what I did. It is stable for now. Let me know. In the end you will be using the roku media server app to access your content from the ex2.
Do you have the Twonky app installed on your ex2 ? To do that go to your dashboard. Then to Apps. you see the Apps choice across the top. There are many apps to can install. Choose Twonky and install it. The next step is to configure Twonky. Once you have installed it it will appear on the left as installed. Click on the twonky server button then choose to configure. The configure choice is right above the run button. The choice will open the configure widow. Then go to shared folders on the left. Navigate over to create this .....Your home drive needs to be where you navigate.
