Modern Xiaomi TVs running on the Android operating system TV PatchWall, or its modifications, are marketed as universal multimedia centers, and users often purchase these devices in the hope of being able to play files from external media without converting. However, real practice shows that not all files are launched by standard means immediately after connection. USB-storage.
Container and codec compatibility is especially important when using high-resolution files such as 4K HDR or Dolby Vision. The standard video player preinstalled by the manufacturer has a limited set of built-in decoders. This means that even if the file has a popular extension, the internal structure of the data flow may not be readable for the regular software. Understanding these limitations avoids frustration when buying media content.
In this article, we will discuss in detail what video formats the TV supports, what the differences between the container and the codec are, and how to get around software constraints with third-party software. You will learn to distinguish between when the problem lies in the bit file and when in the absence of the necessary software decoder, this knowledge will save you time and nerves when organizing a home theater.
Differences between container and codec in Android TV
To understand the playback process properly, you need to clearly distinguish between container and codec. A container is a file shell that defines its extension, such as.mkv,.mp4 or.avi. Inside this shell can be a video stream, audio stream and subtitles. Xiaomi TV primarily reads the file extension to understand which program to open it.
The codec is an algorithm for compressing and encoding video data inside a container. It depends on the codec whether the TV processor can decode the image in real time. The most common are H.264 (AVC) and the more modern H.265 (HEVC) codecs. If the TV supports the MKV container but does not have the hardware support for the HEVC codec, the file will either not start or play with jerks.
Audio codecs are equally important, especially when connecting external acoustics. Formats like Dolby Digital Plus or DTS require a license and hardware capacity. In some Xiaomi models, there is a situation where video is great, but the sound is absent due to incompatibility of the audio stream, so when choosing files to view, you should pay attention to the full set of characteristics of the media file.
β οΈ Note: Availability of file with extension.mp4 does not guarantee its reproduction, since inside can be encoded video stream, which the TV processor is not able to process hardware.
Basic supported video and audio formats
Xiaomiβs regular media player has a basic set of supported formats that cover the needs of most streaming and conventional TV users. The main video container with which the system works most stable is MP4, which provides high compatibility with almost all models of TVs, from budget to flagship.
High-definition video is critically important to support the VP9 and AV1 codec (in newer models), which are used by YouTube and Netflix to stream content to 4K. Xiaomi TVs certified by Google are required to have hardware decoders for these formats, which ensure smooth playback without loading on the central processing unit of the system.
The list of supported containers also includes:
- πΉ MKV β The most popular format for storing high quality films with multiple tracks;
- π¬ AVI β outdated but still common format, often requiring conversion;
- πΊ TS/M2TS β formats used for recording digital television and Blu-ray discs;
- ποΈ MOV β format often found when shooting on Apple devices.
As for audio, basic support includes MP3, AAC, and AC3. However, for formats like DTS, there may be licensing restrictions in some regions of the firmware, in which case the sound may not be played in a standard player, requiring the installation of third-party software.

If the video is playing but there is no sound, try to switch the audio track in the player settings or change the audio output format in the TV settings on PCM.
MKV and HEVC playback problems (H.265)
The H.265 codec MKV format (HEVC) is the gold standard for storing movies in 4K, but it is the one that most often causes problems on Xiaomi TVs.The main difficulty is that decoding HEVC requires significant computational resources.If the TV processor does not have hardware acceleration for this codec, playback will be impossible.
In addition, MKV files often contain embedded subtitles in PGS or VobSub format. Xiaomi's regular player can ignore graphical subtitles, displaying only text SRTs. This creates a situation where the film is going but without translation, making viewing uncomfortable. In some cases, the system may refuse to open the file altogether if it cannot recognize the subtitle structure.
Files with a high bitrate (over 100 Mbps), characteristic of the original Blu-ray rips, can cause slowdowns even on high-power TVs if they are read from slow reading. USB-The storage device. USB 2.0, which is often found in budget models, is physically unable to transmit such a volume of data without delay.
β οΈ Note: When trying to reproduce heavy 4K HDR Make sure the file is using the port. USB 3.0 (usually blue) because USB 2.0 may not be able to handle the data stream.
Codec specifications for Xiaomi and Redmi TV models
Different generations of Xiaomi TVs are equipped with different chipsets, which directly affects the list of supported codecs. For example, models based on Amlogic processors often have more support for out-of-the-box formats compared to some MediaTek solutions in the budget segment.
For clarity, we give a table of formats depending on the generation of devices:
| Generation/Series | Max, permission. | Video codecs | Audio codecs | Features |
|---|---|---|---|---|
| Xiaomi Mi TV (1-2 gen) | 4K 60fps | H.264, H.265 (8 bit) | MP3, AAC, AC3 | No support for Dolby Vision |
| Xiaomi Mi TV P1 / Q1 | 4K 60fps | H.264, H.265 (10 bit), VP9 | Dolby Digital Plus | Support for HDR10+ |
| Xiaomi TV A Pro / F Pro | 4K 60fps | H.264, H.265, AV1 | DTS-HD, Dolby Atmos | Extended HDR support |
| Redmi Smart TV X | 4K 60fps | H.264, H.265 | MP3, AAC | Basic support, DTS possible |
As you can see from the table, newer models are getting support for the AV1 codec, which is becoming the standard for YouTube and other streaming platforms, which saves streaming traffic without losing quality. Older models may not be able to decode AV1 software, so when choosing a TV to stream in 4K, this is a good option to consider.

Using third-party video players to enhance compatibility
If a standard player canβt play your file, the most effective solution is to install a third-party app. Android TV allows you to install any compatible players from the Google Play Store. This bypasses the limitations of the standard software, since third-party applications often have their own built-in codecs.
One of the most popular solutions is VLC for Android, which is known for its ability to play almost any video and audio formats without having to install additional codecs. It takes over software decoding, allowing you to run files that a standard player doesn't even try to open.
Other worthy alternatives include:
- π MX Player β a powerful player with excellent support for subtitles and hardware acceleration;
- π¬ Nova Video Player β perfect for creating a beautiful media library with posters;
- π½οΈ Kodi β a multimedia platform for advanced users with support for plugins;
- π΅ Just (Video) Player is a lightweight player based on the mpv engine, working perfectly with heavy files.
When using third-party players, it is important to keep in mind performance. Software decoding heavy 4K files can load the processor, causing the device to heat up. Therefore, it is still preferable to use files in hardware-supported formats to view ultra-high bitrate content.
βοΈ Choice of video player
Configure audio and video output when incompatible
Often, the problem is solved not by replacing the file, but by setting the TV correctly. If you are faced with a lack of sound in DTS format, try changing the audio output settings. From the Settings β Sound β Digital Sound Output, choose PCM mode instead of Auto or Passthrough. This will force the TV to decode the sound itself, which often solves the problem of compatibility with external receivers.
For video, frame rate and dynamic range are important. In Settings β Display β Image, you can find HDR settings. If the movie looks faded or too contrasting, try switching HDR mode manually. Some files may not be correctly defined by the system, and manual adjustment improves color reproduction.
Also worth paying attention to USB playback settings. Some firmware has Settings β Device Preferences β Drives. Make sure that the formatting of the external drive is NTFS or exFAT file system, as the standard FAT32 file system does not support files larger than 4 GB, which is critical for high-quality video.
β οΈ Note: When switching the audio output to PCM surround 5.1/7.1 It can be lost and converted to stereo if the TV does not support multi-channel decoding. PCM.
