Buying a modern Smart TV from Xiaomi is often the first step to creating a full-fledged home theater without unnecessary costs. Owners of devices with the Android TV operating system or PatchWall proprietary shell strive to maximize the capabilities of the device by connecting external hard drives and flash drives with a media library. However, when faced with a playback error when trying to open a file from a computer or external media, users wonder about the compatibility of codecs.
It is important to understand that the TV hardware and Android TV software have their limitations, despite the stated versatility. Standard media player built into the system supports a wide range of popular formats, but can "choke" when faced with rare codecs or complex bitrate, which is why knowledge of technical nuances and the availability of alternative solutions for content playback is critical for comfortable use of the device.
In this article, we will discuss in detail which containers and codecs Xiaomi’s default technology supports, and we will also look at ways to circumvent restrictions with third-party software that will turn your TV into an omnivorous media center, and you will learn why one file opens instantly, and another requires conversion or installation of an additional application.
⚠️ Note: Xiaomi’s standard player may not display files with bitrates above 100 Mbps or a specific subtitle structure, even if the file format is declared to be supported. USB-porter.
Basic support for video formats in the Android TV system
The operating system that Xiaomi TVs run on is designed to work with the most common video compression standards, the de facto standard being H.264 (AVC), which provides high picture quality at a relatively small file size. Most videos downloaded from the Internet or recorded from digital TV use this codec, so they usually don’t have problems running them.
More modern models with 4K processors can decode H.265 (HEVC) format hardware, allowing ultra-high resolution video to be streamed without any jerks or delays, but support for 10-bit color or specific HDR profiles (such as Dolby Vision) can vary depending on the TV model and firmware version.
As for containers, MP4 is the mother language for the system. Files with this extension are opened almost always, since they contain a standard set of audio tracks and video streams that the system understands without additional manipulation. If your file has an mp4 extension, but does not play, the problem is most likely not in the container, but in the audio codec or damage to the file structure.
- 🎬 MP4 — The most versatile container that supports video, audio and subtitles in a single file.
- 🎬 MKV — A popular format for high quality films, often containing multiple audio tracks.
- 🎬 AVI — Aging but still common format that requires specific codecs.
- 🎬 TS / MTS — formats often used to record video from cameras and digital television.
⚠️ Note: When playing files MKV with “heavy” subtitles (e.g, PGS or graphics) a standard player may ignore them or show them incorrectly.
It’s worth noting that AV1 format support only appears in the newest Xiaomi TVs released in the last year or two.If you’re planning on watching 8K content or high-quality YouTube videos in the future, having this codec in the spec will be an important advantage, although there’s not much mass content in this format right now.
Audio codecs and sound problems
Often, users are faced with a situation where video is coming, but there is no sound. This is a classic sign of the lack of support for a specific audio codec built-in system. Xiaomi TVs, like most Android devices, are great at AAC and MP3 formats. These codecs are used in the vast majority of online services and video files.
This is complicated when it comes to multi-channel home theater sound. Dolby Digital (AC3) and DTS require royalties, so TV manufacturers don’t always turn it on out of the box. As a result, when you launch a movie with a quality sound, you may see an audio format error message or you may see no audio backup.
There are two ways to solve this problem: using an external audio receiver that will take over the decoding, or installing a third-party player.VLC for Android or Kodi have their own software decoders that allow you to bypass system limitations and play sound even in complex formats such as TrueHD or DTS-HD MA.
| Audio codec | Support system | Third-party player required | Quality. |
|---|---|---|---|
| AAC / MP3 | Complete. | No. | Standard. |
| AC3 (Dolby Digital) | Partial | Recommended | 5.1 Surround |
| DTS | No/Partial | Yes. | 5.1 / 7.1 Surround |
| FLAC | Yes. | No. | Lossless |
The FLAC format, which is popular with audiophiles, is worth noting: Xiaomi TVs usually play FLAC files via USB without any problems, but when transmitting over the network (DLNA), it can be difficult to display tags or album covers.
Working with photos and graphic files
In addition to video, Xiaomi TVs are often used as a digital photo frame, bringing family archives to the big screen, basic support for graphic formats is implemented quite widely here. The standard gallery owner easily opens JPEG and PNG files, which make up 99% of all user content.
The situation is ambiguous with the GIF format: a standard viewer can only display the first frame of the animation or refuse to open the file altogether. To view animated images, it is better to use a browser built into the TV or specialized applications from the Google Play Store that correctly handle the cyclic change of frames.
The HEIF (HEIC) format that modern iPhones use by default may not be supported by older Xiaomi TVs. If you want to stream photos from your iPhone directly via USB, the system may not see them, in which case it is recommended to pre-convert images to JPEG or use the screen broadcast function (Cast), where the conversion takes place on the fly by the smartphone.
Use of third-party media players
If the built-in tools can’t play your files, third-party apps come to the rescue. Installing an alternative player is the first action a Xiaomi TV owner must take once the device is turned on, which allows you to expand the list of supported formats to almost limitless.
The leader in this category is VLC for Android, a free, open source application that contains all the codecs you need inside it, and it's "omnivorous" and can play almost any file you throw on a flash drive, including those that the regular player drops out with an error.
Another powerful tool is Kodi, which is not just a player, but a multimedia platform that builds beautiful film libraries with covers and descriptions. Kodi is perfect for those who have a large collection of movies on an external hard drive. The application requires customization, but the result is worth it.
☑️ Selection and installation of the player
Also worth mentioning is the MX Player, which is famous for its user-friendly interface and excellent work with subtitles, which makes it easy to change the size, color and position of text on the screen, which is often necessary when watching movies with “separate” or separate subtitles.
Reproduction over the network: DLNA and SMB
Transferring files from computer to flash drive every time is inconvenient, so many users set up a local network. DLNA and SMB, allowing you to stream content directly from the PC or NAS-It's enough to have both devices on the same Wi-Fi network.
When using DLNA, the TV sees the shared folders of the computer as external sources of signal, you can go to Media or Sources and choose your computer, but this method has limitations: it does not always correctly display the folder structure and may not support some metadata files.
Protocol SMB (Samba is a more reliable and modern way, it provides a stable connection and allows you to work with the file network as a local one. VLC Or Kodi you can add network storage to SMB, lead IP-computer address and account details, after which you will have access to all files without restrictions.
Problems with SMB v1
It is important to consider the bandwidth of your Wi-Fi router. 4K-At 2.4 GHz, the bitrate may not be sufficient, leading to buffering and jerking images, even if the file format itself is supported by the TV.
Frequent problems and ways to solve them
One of the most common problems is the storage file system. Xiaomi's Android TVs are best friends with the FAT32 file system. However, it has a limitation: it doesn't support files larger than 4GB. If you're trying to run a high-quality movie that weighs 20GB, the system will simply not see it or will give you an error.
The NTFS file system standard for Windows supports files of any size, but the TV may require an additional driver or third-party player to work with it. Some Xiaomi models can read NTFS natively, but you can often not write to such flash drives from the TV. The exFAT format is the middle ground, supporting large files and running on most modern Android devices without problems.
Another problem is filename encoding. If your movie titles are written in Cyrillic and the USB drive file system is incorrectly encoded, instead of Russian letters, you'll see a set of characters like???????.mkv. So, this is done by renaming files on your computer or formatting the drive into a compatible file system with the correct encoding.
⚠️ Attention: Don't pull out USB-a drive during playback or indexing of files, which can cause file system damage and data loss. Use the "Safe Retrieval" menu in your TV settings.
If the video twitches or stutters, check the bitrate of the file. Even a powerful TV processor can not cope with streaming above 100-120 Mbps, especially if you use a complex compression codec, in which case only the file conversion on the computer or using a more powerful external player connected via HDMI will help.
Compatibility summary table
To quickly navigate the format compatibility with Xiaomi TVs, you can use the following table, which will help you quickly determine whether you should try to run a file with standard means or you should immediately resort to installing additional software.
| Format | Video codec | Audio codec | Status of support | Recommendation |
|---|---|---|---|---|
| MP4 | H.264 / H.265 | AAC | Native. | Run a standard player |
| MKV | H.264 / H.265 | AC3 / DTS | Partial | You need a VLC or Kodi for sound. |
| AVI | MPEG-4 / Xvid | MP3 | Native. | It works well, old codecs. |
| WebM | VP9 | Opus | Depends on the model. | Check on a specific model |
In conclusion, Xiaomi’s ecosystem provides flexible multimedia tools, knowing which formats the shaomi TV reads out of the box, and having a couple of proven player apps on hand, you can play almost any digital content available today on your screen.
