The Chinese manufacturer’s modern Smart TVs have long since ceased to be just screens for watching terrestrial TV, becoming powerful multimedia centers. Device owners often wonder what video formats their TV can decode to enjoy high-resolution content without converting files. The hardware platform used in most models of Xiaomi Mi TV and Xiaomi Mi Box is based on Amlogic or MediaTek processors, which have native support for a wide range of containers and codecs.
Understanding the technical limitations and capabilities of your model will help you avoid situations where a file is not opened or played without sound. In this article, we will discuss in detail the list of compatible extensions, the differences between containers and codecs, as well as methods for solving problems with incorrect reproduction of heavy loads. 4K-content.
The basis of compatibility is the Android TV operating system, which provides a basic set of drivers, but hardware acceleration plays a key role here, and it depends on the chipset whether the TV can smoothly play video with a bit rate above 100 Mbps or files encoded in the latest HEVC standard (H.265).
Hardware codecs and compression standards
The heart of any multimedia device is a chipset that takes on the task of decoding the video stream. Xiaomi TVs are equipped with modern SoCs capable of processing video at up to 8K resolution, although the mass segment is focused on 4K Ultra HD. It is important to distinguish between a container (file extension) and a codec (a way of compressing data inside a file), since the TV can read the container but do not have codec hardware support.
The most common compression standard at the moment is H.264 (AVC), It's supported by all models, without exception, but for quality viewing. 4K-Content from disks or local area networks is critical to codec support H.265 (HEVC). The decoding module in Xiaomi processors effectively copes with 10-bit color and HDR-metadata, which ensures correct color reproduction.

For professional content and HDR-Support for the standard is also important. HDR10 and HLG. Hardware decoders in current Mi lines TV P1 mi TV Q1 They are fully compatible with these formats, allowing you to unlock the potential of the matrix. AV1, which is beginning to gain popularity in streaming services, then its reproduction is possible only on the newest models with an updated hardware platform 2026-2026 year-end.

Use an HDMI 2.1 cable to transfer 4K HDR content from external devices to ensure sufficient channel bandwidth.
List of supported video containers
A container is a shell that stores video stream, audio tracks and subtitles. Android operating system TV On-board Xiaomi TVs, it provides native support for most popular formats. Users can run files directly from the TV. USB-drive or through a local network using an embedded player or third-party applications.
Among the most common formats that are guaranteed to work on Xiaomi Mi TV devices, the following can be distinguished:
- 🎬 MKV — The most popular high quality film storage container, supporting many audio tracks and subtitles.
- 🎬 MP4 — Universal format compatible with all devices, often used for recording and streaming.
- 🎬 AVI — The legacy format, which is still found in archives, requires codec verification inside the archives.
- 🎬 MOV — The format often used in Apple products is reproduced by regular means.
- 🎬 TS / M2TS — Transport flows characteristic of Blu-ray discs and satellite television.
Particular attention should be paid to the format MKV, Because it's where users most often store rips of torrent movies. Xiaomi TVs are great at navigating chapters inside. MKV-If the container is inside the container, MKV Use a rare or outdated audio codec, video sequence can go, and there will be no sound.
The WebM format, popular on the Internet, is also supported, but mainly through a browser or applications like YouTube. Third-party players are better for locally playing heavy WebM files, since the in-house gallery owner may not recognize the structure of the file.
Audio codecs and sound problems
Video without sound loses half its value, and it is the audio track that often becomes a stumbling block when playing files on Xiaomi TVs. While the video part is processed hardware, audio decoding can fall on software components of the system, which do not always include licensed codecs.
Basic sound formats like AAC, MP3 and PCM play without problems on any model.The situation is complicated when it comes to multi-channel audio for home theaters. Dolby Digital (AC3) and Dolby Digital Plus formats are supported hardware in most modern models, allowing you to output audio through optics or HDMI ARC to the receiver.
⚠️ Note: Lack of codec support DTS In some regions or models, Xiaomi is a software limitation, not a hardware one, but it is impossible to bypass it with regular means.
If you’re experiencing a lack of sound in a file where the video sequence is going well, it’s likely that the problem lies in the DTS or DTS-HD audio codec. In such cases, the TV may display a format error message or simply remain silent, due to licensing restrictions that Xiaomi has to comply with in different countries.
To solve the problem, you can use an external audio receiver that will take over the decoding, or broadcast the sound to the sound system via Bluetooth, if it supports the necessary codecs.
Using third-party players for enhanced compatibility
The regular media player preinstalled on Xiaomi Mi TV has basic functionality and relies on system codecs. For users who store the media library on hard drives or NAS, it is strongly recommended to install third-party applications from the Google Play store. These programs have their own decoding libraries and are not subject to the limitations of the operating system.
One of the best solutions is to install a VLC for Android player. This application is "omnivorous" and is able to play almost any format you can find on the Internet, including corrupted files and streams with non-standard bitrate.
Another powerful tool is the MX Player. Unlike VLC, it requires separate codec installation for some formats, but provides more flexible playback settings, including fine-tuning subtitles and audio tracks. For advanced users, a hardware acceleration mode is available that reduces the load on the processor.
☑️ Selection and configuration of the player
And you also have to look at home theater apps like Kodi or Nova Video Player, which not only play videos, but also create a beautiful library with posters and descriptions, pulling information from the Internet, and that turns the TV into a full-fledged media center.
Compatibility table for codecs and extensions
For a quick orientation in technical specifications, we will give a summary table, which reflects the degree of support for various formats on Xiaomi TVs with Android TV OS. The data is relevant for models released between 2020 and 2026.
| Format/Code | Support | Max, permission. | Note |
|---|---|---|---|
| H.264 (AVC) | Complete. | 4K @ 60fps | Basic Standard, Works Everywhere |
| H.265 (HEVC) | Complete. | 4K @ 60fps | Required for HDR and 4K content |
| VP9 | Complete. | 4K @ 60fps | Used on YouTube |
| AV1 | Partial | 4K @ 30fps | Only the new 2026+ models |
| MPEG-2 | Limited. | 1080p | For the old ones. DVD-rip-off |
The table shows that modern compression standards are well maintained, but with outdated formats, nuances can arise. For example, MPEG-2 can be played in jerks on budget models if the file has a high bitrate.
What to do if the video slows down?
Reproduction over a local area network (DLNA and SMB)
Watching video directly from a flash drive is a thing of the past, giving way to streaming over a local network. Xiaomi TVs work great with SMB and DLNA protocols, allowing accessing files on a computer or NAS without using physical media. This is especially true for high-volume files, where USB 2.0 speeds can be a bottleneck.
Network broadcasting requires that the TV and the file source are on the same subnet, and the built-in Media Player app can scan the network and find available resources, but for stable work with heavyweights. 4K-It is better to use specialized clients, such as VLC Or Kodi, which buffers the flow better.
When you set up SMB-It is important to use the protocol version of the server on the computer. SMB v2 or v3, Because support is outdated SMB v1 Android TV It can be restricted or disabled for security purposes, and it will provide maximum data transfer speed and stability of the connection.
💡
Using wired Ethernet instead of Wi-Fi significantly improves the stability of 4K video playback over a local network.
