If your phone is full of movies, TV shows, or music and you're tired of copying everything to a USB drive or hard drive to watch it on TV, you'll want to know what DLNA is and how to get the most out of it. With the right apps, you can Turn your mobile phone into a DLNA server and send the content directly to your TV, laptop, tablet or any compatible device on your network, wirelessly and hassle-free.
The beauty of all this is that with a little configuration you can use both your Android and your iPhone as wireless media centerTake advantage of your Windows PC or even a Linux server with MiniDLNA to have a centralized library, and then play everything on your Smart TV without depending on USB drives, Chromecast or other extra gadgets.
What is DLNA and how does it actually work?
DLNA stands for Digital Living Network Alliance, a specification that defines how different home devices (mobile phones, computers, NAS, TVs, consoles…) can share and play multimedia content within the same local network. It relies on the UPnP (Universal Plug and Play) protocol, which is responsible for the automatic discovery of devices and services.
In a DLNA network there is always at least one device that acts as media server (where the content is stored: video, photos, music) and one or more clients or players (the TV, another mobile phone, a tablet, a game console, etc.). All of this works over the local network, either by Wi-Fi or Ethernet cableSo as long as all the devices are connected to the same router, they should be able to see each other.
When you connect two compatible devices using DLNA, the client is able to browse the server's media library and play files directly without needing to copy them. It's like accessing a smart shared folder that already organizes and presents movies, music, and photos in an orderly fashion for viewing on your TV or other device.
One of DLNA's strengths is that it tries to make everything as "plug and play" as possibleThe server advertises itself on the network using multicast/UPnP, and clients automatically detect what's available. However, each device must be compatible with DLNA/UPnP and the audio and video formats you want to play.
Advantages, limitations and optimization of DLNA streaming
Using DLNA at home has several clear advantages: it allows you to reuse devices as multimedia serversYou save time by avoiding copying files, you avoid filling up USB drives, and you simplify how you view content on different screens. Ideal, for example, for using your PC or mobile device as the "central library" and having your Smart TV simply play content.
However, there are also some significant disadvantages to consider. For one thing, the system is heavily dependent on the format compatibilityThe server and player must understand the same codecs (H.264, MP4, MP3, etc.). For example, if you have a video in HEVC/H.265 or an MKV with certain subtitles, your TV might not play it if the server doesn't transcode it.
Another important limitation is that DLNA only works on local networksIt's not designed for viewing content outside your home over the internet. Furthermore, the protocol itself doesn't implement authentication or encryption, meaning that on a shared or unsecured network, anyone could potentially access your media library if you leave it open.
Since streaming is now commonplace, many manufacturers and developers have been optimizing the DLNA experience. One of the keys is the efficient data compression, with codecs that greatly reduce the size while maintaining reasonable quality so that playback is smooth even with less-than-perfect Wi-Fi connections.
Also important is the prioritization of multimedia trafficOn some routers, you can prioritize this type of traffic to avoid interruptions and buffering, especially when multiple people are using the internet simultaneously. In addition, connection management has been improved to reduce connection times, recover from outages, and perform better on wireless networks.
New network technologies, such as Wi-Fi 5, 6 or 6E and better chipsets in routersThese improvements have helped make DLNA transmissions much more stable. Even so, for high-bitrate content (for example, very large 4K movies), continuing to use Ethernet cable at the server or TV can make a difference.
Common risks and problems with DLNA
In everyday use, it's quite common for a DLNA device not to appear in the Smart TV's list or for a mobile device not to see the PC's server. This type of failure is usually related to UPnP discovery problems and multicast trafficwhich is what DLNA uses to advertise and discover services within the home network.
If your TV doesn't recognize your PC or mobile device, you should check that all your devices are compatible. They are on the same IP subnet (for example, 192.168.1.x), indicating that the router isn't isolating Wi-Fi clients from each other and that multicast/UPnP traffic isn't blocked by the router or a firewall. Sometimes disabling the "AP isolation" option or checking the Windows firewall is sufficient.
Regarding reproduction, another classic is the format and codec incompatibilitiesDLNA "officially" recommends certain standards (H.264/AVC, MP4, MP3, etc.), but in practice many TVs have problems with containers like MKV with embedded subtitles, or with more modern codecs like HEVC/H.265 if the server only sends the file as is.
To mitigate this, many applications like Plex or VLC include real-time transcodingThey convert the video "on the fly" to a format the client understands. This consumes CPU on the server device, but in return, it saves you from having to manually recompress your entire collection or struggle with what each TV understands.
Constant interruptions and pauses during a movie are also very common when the network connection is slow. In these cases, it's advisable to check the Wi-Fi connection quality, network congestion, and router firmwareIf possible, connect the server via cable, and if the TV uses Wi-Fi, switch it to the 5 GHz or 6 GHz band to minimize interference.
Finally, don't forget that DLNA lacks native encryption and strong authenticationIn a closed home network, this is usually not a problem, but in shared networks (for example, apartments with multiple tenants), it's advisable to restrict the devices that can connect to the server, disable it when not in use, and consider using a VPN or network segmentation if you're concerned about privacy, or activate a near-total privacy mode on your mobile.
Turn your Android mobile into a native DLNA server
Many Android phones include a built-in feature for Set up a DLNA-compatible media serverAlthough it's usually quite hidden in the settings. This way, your smartphone becomes another resource on the local network, accessible from your TV, computer, or any other compatible device without having to install anything additional on them.
Generally, on Android, the process involves enabling a media server option in the connection settings. On many models, you need to go to “Connecting devices” or “Connected devices”Then go into something like "Connection Preferences" or "Media Sharing" and, within that, locate a menu called "Media Server", "DLNA Server" or similar.
Once inside that menu, you can activate an option like this: “Share content”This is what makes the phone start advertising itself on the network as a DLNA server. It usually also lets you choose what type of content you want to share (music, photos, videos) and in some cases filter by folders.
When you activate this feature, your phone will appear as a new media device in network browser Windows, many Smart TVs, and other apps or devices compatible with DLNA/UPnP. You can directly play photos, vacation videos, or your music without having to copy them anywhere, and everything will play in real time from your phone's memory.
In that same media server menu there is usually a section for access control This allows you to decide which devices on the network can connect, whether confirmation is required for each one, or whether access is always allowed. This is very useful for preventing content from being left wide open to any device that connects to the router.
Recommended DLNA apps for Android
In addition to the native function on many phones, there are several very powerful apps that allow you to Use your Android device as a server, client, or both.With them you can access a NAS, a PC or the cloud and send the content to the TV, or vice versa, share the content of your mobile with other devices on the network.
Kodi
Kodi is one of the best-known media centers on the scene. Although it became famous for its add-ons for watching online content, it can also act as a DLNA client and server within your home network. From the Android app, you can access content stored on other devices or share your own library.
The usual way is to install Kodi from Google Play To avoid modified or malware-infected versions. Once your video, music, or photo folders are configured, you can activate the UPnP/DLNA server options and allow other clients (TVs, other Kodi, VLC, etc.) to view and play that content.
Among the most interesting features of Kodi are its multiple add-ons, the ability to access content saved on other devices and its frequent updates, which fix bugs and add features to improve compatibility with formats and devices.
plex
Plex is another very popular solution for setting up a complete media server, whether on a PC, a NAS, or even directly on your mobile device. The Android app can Establish DLNA connections and stream content to Smart TV or other network devices, in addition to working with its own Plex client system.
Its greatest strength is its simple interface and how well it... organizes the multimedia libraryIt includes movies, series, cover art, synopses, seasons, etc. It also offers free streaming TV channels, so it's not just for playing local files, but also for watching online content.
To use Plex with your TV, simply install the app on your mobile device, log in, go to system settings, and activate the option. “Advertise as server”Then download Plex on your Smart TV, log in there, and you'll see everything on your phone on the screen, as long as both are on the same Wi-Fi network.
BubbleUPnP
BubbleUPnP is one of the most versatile Android apps when it comes to playing and streaming content via DLNA/UPnP. With it you can connect to virtually any DLNA server (PC, NAS, another mobile) and send photos, music or videos to a wide variety of players, including many Smart TVs and Chromecast devices.
The app not only plays files stored on your phone; it also allows access to Cloud services such as Google Drive, Dropbox, Google Photos, Box, or OneDriveas well as to music platforms like TIDAL or Qobuz, and send that content to other devices without downloading it first.
Among its strengths is the ability to send what you're seeing to Chromecast or compatible devicesIt acts as a local player and serves as a "bridge" between different UPnP/DLNA servers and clients, making it a kind of Swiss Army knife of home streaming.
LocalCast
LocalCast is a lightweight and very practical alternative for sending content from your mobile device to different devices. It allows connect to local DLNA computers and servers, as well as cloud servicesand at the same time send photos, videos and music to Chromecast and other compatible players.
One of its attractions is that it includes video customization options More advanced than other similar apps: you can zoom, rotate, pan the image or load external subtitles, which is great if you like to watch content in its original version or have separate subtitle files.
However, LocalCast does not act as the final player itself when it comes to TV, but rather You need a Chromecast-type device or similar. where to send the content. On your mobile device you can preview or play it, but the magic of "casting" is always done to another device.
Airscreen
AirScreen is an app focused on receiving content: it turns your Android device into a receiver compatible with different wireless protocolsThese include Miracast, AirPlay, Google Cast, and DLNA. Although the free version includes ads, it's a very complete option for "listening" to what other devices are sending.
Thanks to AirScreen you can, for example, mirror the screen of other devices or receive streams from applications like YouTube or browsersIt includes extra features such as screen recording and places special emphasis on protecting the privacy of data passing through the app, something that is increasingly valued.
MediaMonkey
MediaMonkey for Android is primarily focused on music, but it's also a great ally when you want synchronize and play large audio collections between different devices. It integrates seamlessly with MediaMonkey for Windows, with which it can sync wirelessly.
The application allows Stream music to UPnP and DLNA devicesAccess your entire music library and playlists from any compatible device on the same network and organize your songs like an advanced music manager. However, the free version has time limits for Wi-Fi streaming.
Among its advantages, the support for multi-zone playback and remote controlIn addition to fast synchronization across all your Android devices, if music is your priority and you want DLNA to function as a smart home music system, MediaMonkey covers virtually all your needs.
DLNA options for iPhone and iPad
On iOS the scope is somewhat more limited because Apple is more restrictive on certain network integrationsHowever, there are still very reliable apps for taking advantage of DLNA and playing content on your local network. Some of the solutions we've already seen on Android also have versions for iPhone or iPad.
VLC for iOS
VLC is the classic video player with the orange cone logo and is available for both computers and mobile devices. On iOS, it allows you to open not only locally stored files, but also... access DLNA and UPnP servers from your network to stream content from your iPhone or iPad.
One of its biggest advantages is that it supports a huge number of video and audio formatsincluding many features that native TV apps don't typically understand. Furthermore, it can connect to cloud resources and network streams, making it a fairly comprehensive playback center.
Video & TV Cast
Video & TV Cast is designed specifically for send content from iOS devices to other devices using protocols like DLNA and UPnP. With it, you can stream to TVs and various casting devices, and even use your iPhone as a small server accessible from other devices.
Their approach is quite specialized: it focuses on turn your mobile phone into a DLNA content source that other apps and devices can discover. It's compatible with servers and platforms like Plex, Kodi, or Serviio, making it another piece within a more complex multimedia ecosystem.
LocalCast for Chromecast on iOS
LocalCast also has an iOS version, and it maintains the same philosophy as on Android: it allows you to connect to any DLNA or UPnP server available on the network and play content on cast devices or in the app itself.
Again, you can send local files or play from the cloud, and it features Settings to modify the video presentation and subtitlesBeing multiplatform, it is especially useful if you have Android, iPhone and tablets of all kinds at home, since everyone can use the same app to manage streaming.
How to use DLNA on Windows as a server for your mobile phone and TV
If you have a Windows computer full of movies, TV shows, and music, you can use it as centralized DLNA server for the entire houseWindows 10 and Windows 11 include a built-in multimedia streaming feature which, when activated, turns the PC into a server accessible from mobile phones and TVs.
To configure it in Windows, you need to go to Control Panel, go to “Network and Internet” and then to “Network and Sharing Center”In the side panel, you'll find the option "Change advanced sharing settings." Within "All networks," you can enable "media streaming."
When you activate this feature, Windows starts to Advertise your media library as a DLNA serverIn Windows 11, the steps are very similar: access the Control Panel, go to "Network and Internet," enter the Network and Sharing Center, and there locate the "Media streaming options." From there, you choose which devices can view the content and what type of files are shared.
With this, any compatible Smart TV, as well as mobile phones with DLNA apps (Kodi, VLC, BubbleUPnP, LocalCast, etc.), should be able to View your PC as a server and access your music, video, and photo libraryIt's a very convenient way to avoid duplicating collections and to make the most of your computer's storage.
Setting up an advanced DLNA server on Linux with MiniDLNA
If you prefer a more technical and flexible solution, on Linux you can install MiniDLNA (often called minidlna or ReadyMedia), a lightweight server that fits very well with low-power equipment, home servers or even Raspberry Pi.
The basic installation on many Debian or Ubuntu-type distributions is done with a simple command apt-get or aptFor example: install the minidlna package from the official repositories. Once installed, all configuration is centered around the file /etc/minidlna.confwhere you define which folders will be shared and how the server will be advertised.
In that file you can specify, using several lines media_dirwhich paths contain audio, video, or images. For example, mark a folder as type “A” for audio, “V” for video, and “P” for photos. You can also customize the friendly server name that DLNA clients will see, as well as specifying where to store the database and the album art cache.
Other file options allow you to set the Log level, ad intervals, if you want strict adherence to the DLNA standardWhat filenames to use as album art, whether you want TiVo support, the HTTP port, the network interface, etc. There's even a parameter to define which container will be the root of the navigation tree (by folders, by music, by video, by photos...).
To manage MiniDLNA as a system service, a startup script in /etc/init.d which allows you to start, stop, restart and check the server status using standard commands such as serviceThis script can be registered at runlevels using tools like update-rc.d so that the service starts automatically with the system.
Normally, you will have to give script execution permissions (for example with chmod a+x /etc/init.d/minidlna) and then enable it with the corresponding command for your distribution. From there you can use commands like “start”, “stop”, “restart” or “status” to control the media server.
When you add new content to shared folders, it may be necessary force a reindexing of the databaseThis is done by running MiniDLNA with special parameters (for example, specifying the configuration file and the index rebuild option). After that, the new files will appear on the DLNA clients without any problems.
By combining native Android and iOS features, specialized apps like Kodi, Plex, BubbleUPnP, LocalCast, VLC, or MediaMonkey, and servers integrated into Windows or Linux with MiniDLNA, it's possible to set up a very complete home streaming system where Your mobile phone becomes a true DLNA server and the rest of the devices on the network simply play the content conveniently, quickly and without having to copy files from one place to another.
