Modern Xiaomi TVs running on the Android operating system TV Or PatchWall's own shell, which is a multimedia center with the greatest possibilities, but when you try to play a downloaded movie or music track through the Internet. USB-Users often face a situation where the file simply does not open.The built-in video player can give an error "Format is not supported" or play only sound without an image. Understanding which codecs and containers your TV can decode is critical to making it comfortable to use without having to dance with a diamond.
The main reason for the problems lies in the difference between the file container and the video stream inside it. The TV can read the.mkv extension, but does not have hardware support for a specific audio codec, such as DTS, which leads to no sound. In this article, we will discuss in detail the technical specifications of the Xiaomi Mi TV and Mi Box media engines, consider compatibility tables and offer software solutions for running files that the regular player cannot digest.
It’s worth noting that format support can vary slightly depending on the model’s year of release and the firmware version installed. Newer models like the Xiaomi TV P1 or Mi TV Q1 come with more powerful chipsets that can decode 4K video at 60 FPS using the HDR10+ standard. Older models can be limited to Full HD and basic H.264. So if your TV refuses to play a file that works well on a smartphone, it may be due to the hardware limitations of a particular year of release.
Hardware and software limitations of the media player
The fundamental support for formats on Xiaomi TVs is determined by two factors: the capabilities of the chipset (SoC) and the licenses of the operating system. The device processor contains special blocks - decoders that process the video stream hardware. If the file is compressed by an algorithm that physically can not read the chip, no software will help. Most often restrictions apply to old codecs like MPEG-2 or specific audio formats like DTS-HD, which the company may not have purchased licenses to reduce the cost of the device.
⚠️ Warning: Attempting to force a video with a bitrate above the processor’s hardware capabilities (for example, 100 Mbps on a budget model) will lead to constant slowdowns, sound dissynchronization and possible overheating of the device.
The software part, represented by the shell of Android TV, A standard video player can often read more formats than the interface shows, but is lazy to open files with certain extensions. USB-The drive plays an important role: TVs based on Android usually read without problems NTFS and FAT32, but may ignore the exFAT or ext4 without installing additional drivers or superuser rights.
Why is the file not playing, even though the format is on the list?
It is important to distinguish between container and codec support. The container is a "box" (e.g.,.mkv,.avi,.mp4), and the codec is a way of packing video and sound inside (e.g., H.265, VP9, AAC). The TV can successfully open the "box" but stumble on the content. For example, the.mkv container is supported by almost all models, but if the video is compressed into AV1 (new standard) and the 2018 TV chip, playback will not be possible.
Supported video and codec formats
The main formats that are guaranteed to work on most Xiaomi TVs are based on the standards used in YouTube and Netflix.This ensures compatibility with the main stream of content. The key compression standard today is HEVC (H.265), which allows you to stream high-resolution 4K video with a smaller file size compared to the old H.264. Virtually all Mi TV models released after 2019 have H.265 and VP9 hardware support.
- 🎬 MP4 (MPEG-4): The most versatile format supported on 100% of devices, usually with a codec H.264 audio AAC.
- 📦 MKV (Matroska: Popular high-quality movie container, supports multiple audio tracks and subtitles, requires a powerful processor to make the movie work. 4K.
- 📺 TS / M2TS: Formats often used in digital TV and Blu-ray discs are supported by most Xiaomi models.
- 🎞️ AVI: Aging format that can only be supported by basic resolution and codec Xvid/DivX.
Special attention should be paid to support for the HDR standard (High Dynamic Range). Xiaomi TVs with support for Dolby Vision and HDR10+ are able to correctly display colors and rage only if the video file contains the appropriate metadata. If you run an HDR file on your TV without support for this standard, colors may look faded or, conversely, unnaturally saturated. Check the specifications of your model can be found in the Settings → Device → Specifications.
When using the VP9 codec, which is often used in YouTube 4K videos, Xiaomi TVs show excellent results thanks to the optimization of Android TV. However, if you are trying to play video with the AV1 codec (used on YouTube for 8K and quality 4K), make sure that your model belongs to the 2021 lineup or later. Older chipsets simply do not have a physical decoding unit for this format, and the TV will not be able to programmatically emulate it due to a lack of power.
Audio formats and sound problems
The audio situation on Xiaomi TVs is often more complicated than video, due to Dolby Laboratories’ licensing policy and the company’s own business. DTS. Many budget and mid-range Xiaomi TVs don’t have a built-in format decoding license. DTS. As a result, when the film is launched DTS-The user sees the image with the sound, but hears silence or static noise.
There are several ways to solve the problem of no sound in files with an unsupported audio codec, and the easiest way is to convert the audio track on the computer into a format. AAC or AC3, A more difficult but convenient option is to use third-party software that can transmit a digital signal directly to a receiver or soundbar without passing the TV's internal decoder. S/PDIF or HDMI ARC.
| Audio format | Support for Xiaomi TV | Note |
|---|---|---|
| AAC | Complete. | Standard for MP4 and streaming. |
| AC3 (Dolby Digital) | Complete. | The main format for DVD and digital TV. |
| DTS | Partial/No | Depending on the model, it often requires external acoustics. |
| FLAC / WAV | Complete. | To play music without loss. |
⚠️ Note: If the sound is lost while playing the film, but the video is coming, do not rush to reset the settings. In 90% of cases, the problem is precisely the lack of a license for the audio codec. DTS in your particular television model.
For audiophiles that connect the TV to a home theater, it is important to configure the output of the audio in the Settings → Sound → Out menu. Select PCM mode if your acoustics do not decode multichannel formats, or Auto / Bitstream if you want the TV to transmit the original signal to the receiver for processing.
Reproduction of images and documents
Xiaomi TVs are often used as a digital photo frame or for viewing presentations. For static images, format support is almost complete. Standard JPEG and PNG formats open instantly. However, when working with high-resolution files (for example, panoramic photos from 20+ MP cameras), there can be delays when flicking, as the TV spends time zooming to 4K resolution.
Document support is more complicated. Android TVs can't open PDF, DOCX or XLS files with built-in tools. You need to install specialized applications from the Google Play store, such as Office Viewer or Google Docs. Without installing additional software, when you try to open a document from a flash drive, you will see a message that you can't play the file.
- 🖼️ JPEG / JPG: Basic format, supported without file size restrictions, but there may be problems with very large resolutions.
- 🎨 PNG: Supports transparency, ideal for logos and graphics, loads a little longer JPEG.
- 📄 GIF: Animated images can only be played as a static frame in a standard gallery, for animation you need a browser or application.
- 📷 RAW: Formats of raw data from cameras (.cr2,.nef) not natively supported, conversion is required.
If you plan to use a TV to show high-quality photos, it is recommended to pre-prepare a slideshow on your computer.This will save the TV processor from unnecessary load and ensure a smooth change of frames. It is also worth considering that Xiaomi TVs can display color profiles (sRGB, Adobe RGB), so the colors on the screen may differ from those you saw on the monitor calibrated for graphics.
💡
Use Movie or Standard mode when viewing photos to avoid excessive color saturation, which is often found in Bright mode by default.
Solving problems with incompatible files
What to do if your favorite movie is.mkv with codec DTS The most effective and popular solution is installing a third-party video player. In the Google Play store on Xiaomi TV, powerful applications are available that have their own built-in codecs and do not depend on the system limitations of Android. TV. The leaders in this niche are VLC for Android and Nova Video Player.
These apps can programmatically decode almost any video stream that doesn't pull a standard player, and they can automatically upload subtitles, create movie libraries with posters and descriptions, and support SMB and DLNA network protocols to play files from a computer without using a flash drive, and installing such a player solves 99 percent of format problems.
☑️ Installation of a third-party player
Alternatively, you can cast a video from your smartphone or tablet to your TV, and you can run a file on your phone that contains all the codecs, and you can display it on your Xiaomi Mi TV through Chromecast built-in or Mi Play. In this case, the TV acts as a monitor, taking a decoded video stream over Wi-Fi. This is especially true for formats that the TV does not support hardware, but can display through broadcast.
File system configuration USB-storage
Even if the video format is supported, the TV may not see the flash drive itself. This is a common problem with large-volume drives (over 64 GB) that are formatted into the NTFS or exFAT file system. Although Android TV claims to support NTFS, the implementation of drivers in different versions of Xiaomi firmware can work unstable. The TV can see folders but not open files, or not respond to the connection at all.
For maximum compatibility, formatting is recommended. USB-file-system FAT32, If you plan to store files smaller than 4 GB. FAT32 It can be read by any device without exception, but it's a format that's limited to the size of a single file. 4K, frequent-weight 20-50 GB, FAT32 It's not good. Then use it. NTFS, But make sure the TV recognizes the drive. If you don't, try reconnecting the drive to another one. USB-port, preferably blue (USB 3.0), if available.
⚠️ Note: When formatting the flash drive in FAT32 All data will be deleted. Make sure to back up your files on your computer before you do this. For movies over 4GB, use the same file. NTFS.
It is also worth mentioning about nutrition. USB-If you connect an external hard drive (HDD), It might be running out of current from one port of the TV, in which case the disc might be clicking, and the TV would be writing «USB-The device is not recognized. The solution is to use USB-a self-powered hub or Y-cable that takes current from two ports at the same time.
💡
The perfect bundle for watching movies on Xiaomi TV: NTFS flash drive + VLC video player + files in the MKV container with AAC audio. This guarantees compatibility by 99%.
