What video formats play Xiaomi TV: a full guide

Smart TV owners from the Chinese brand often wonder about the compatibility of multimedia files, especially when the built-in player refuses to run a downloaded movie, a situation where the device emits a โ€œFormat not supportedโ€ error or only plays sound without an image, is familiar to many users of the MIUI for TV ecosystem.

Understanding the difference between a container and a codec is key to successful content playback. Many users mistakenly believe that file extensions (such as.mkv or.avi) will guarantee its launch, but inside the container can be packed video stream that the TV processor cannot handle hardware. In this article, we will discuss in detail the technical nuances, supported codecs and ways to solve the problems with the playback of โ€œheavyโ€ files on Xiaomi Mi TV and Redmi Smart TV.

Differences between container and codec

The first thing you need to learn to work with a media library is the fundamental difference between a container format and a video codec. A container is a wrapper that stores video stream, audio tracks, subtitles and metadata. A Xiaomi TV can easily recognize the container itself, such as an MKV or MP4, but this does not mean that it will be able to decode the content. It is the internal codec that is responsible for compressing and decompressing images in real time.

Today's TVs are equipped with hardware decoders that take the bulk of the video processing workload. If the file is encoded in the popular H.264 (AVC) standard, almost any budget TV can play it. However, when you switch to more efficient new-generation codecs like HEVC (H.265) or AV1, the hardware demands increase. Older Mi TV Sticks or early versions of TVs may simply not have a physical module to break such streams, leading to jerks or a complete failure of launch.

โš ๏ธ Note: Availability of file with extension.mp4 It does not guarantee its playback, as an audio codec that is not supported by Android can be used inside. TV free-source.

Audio codecs are often the hidden cause of problems. Videos can go perfectly, but sound will be absent if the file uses the DTS or DTS-HD format. Licensing these codecs is paid, and Xiaomi, like many other Android device manufacturers, often does not include DTS support in the standard firmware, limiting itself to free AAC or AC3. This is an important nuance to keep in mind when choosing content sources.

List of supported video codecs

Xiaomiโ€™s TV hardware platform is based on chipsets from MediaTek or Amlogic, which have a well-defined set of supported video compression standards. The basic standard for all models is H.264. This codec provides good quality at a reasonable file size and is used in the vast majority of videos from the Internet and DVD-quality rips.

For owners. 4K-TVs are critically important to codec support H.265 (HEVC). It allows you to compress high-resolution video twice as efficiently as its predecessor. TV redmi TV reproduce H.265 with a bitrate of up to 100 Mbps and above, however, it is worth considering that support for 10-bit color and HDR Within this codec, it can vary depending on the specific processor model.

Below is a table of compatibility of the main video codecs with the Android TV operating system on Xiaomi devices:

CodecMaximum authorizationSupport for HDRStatus of support
H.264 (AVC)1080p / 4KNo/PartiallyComplete.
H.265 (HEVC)4K / 8KYes (HDR10)Full (on 4K models)
VP94KYes (HDR10)Complete (for YouTube)
AV14K / 8KYes.New models only (2021+)
MPEG-21080iNo.Limited.

Googleโ€™s VP9 codec is natively supported by all Android TVs and is used primarily for streaming YouTube in 4K. If you plan to watch YouTube in high resolution, VP9 Profile 2 support is a must, and Xiaomi TVs usually donโ€™t have that problem.

What is AV1 and do you need it?
Codec AV1 โ€” It is a new open standard for video compression that provides better quality with less bitrate compared to the previous one. H.265. It's becoming the standard for streaming services like Netflix, but for viewing local files from the Internet. USB-The support of the drive is not critically important yet, since content in this format is rare.> When it comes to containers, Xiaomi TVs show enviable flexibility. The standard Mi Video video player or Android system player has no problem opening files in shells MKV, MP4, AVI, MOV and TS. Problems begin when the container structure is disrupted or exotic thread multiplexing techniques are used, which is sometimes found in files downloaded from torrent trackers. As mentioned earlier, Google and TV manufacturersโ€™ licensing policies often exclude format support. DTS. If you are running a movie with an audio track DTS, You're more likely to see a black screen or a sound error message (AC3) Dolby Digital Plus (E-AC3) Supported by most models, providing surround sound through HDMI For a comfortable viewing, it is recommended to focus on the following bundles of container-audio: ๐ŸŽฌ MKV + AAC/AC3 โ€” perfect compatibility, working on 100% device. ๐ŸŽฌ MP4 + AAC โ€” Standard for content from the Internet, no problems. ๐ŸŽฌ AVI + MP3 โ€” Older format, may require more processor resources to decode. ๐ŸŽฌ MKV + DTS โ€” high risk of sound loss, transcoding or third-party player required. If you often encounter files where video is coming and there is no sound, check the file properties on your computer. Most likely, the DTS codec will be listed in the Audio column. In this case, it makes sense either to convert the file or use software solutions, which will be discussed below. Using third-party video players, the standard player preinstalled in the Android TV system often does not cope with complex files or incorrectly displays subtitles. The solution to this problem is installing third-party software. The Xiaomi Store provides powerful software for the Android Play Store, which provides access to the most powerful software tools for the Android VLC. This player can digest almost any video and audio formats, including those very problematic DTS tracks that the system ignores. VLC also has flexible subtitle settings and allows you to change the audio delay, which is useful when viewing files with desynchronization. Another great alternative is the MX Player player. It is famous for its hardware acceleration and easy navigation gestures. However, it is worth noting that the free version of the MX Player may also lack AC3 and DTS codecs due to licensing restrictions, but they can be added to the official codecs from the site settings. โ˜‘๏ธ Choosing a video player for Xiaomi TVCheck availability in Google Play Store Evaluate the user-friendliness of the interface from the remote Check support for subtitles Test run problem file: 0 / 4 Reproduction with USB-drives and over the network When connecting an external hard drive or flash drive to the port USB Xiaomi TV, it is important to consider not only the video format, but also the file system of the drive. TV Usually reads file systems without any problems. FAT32 and NTFS. However, the file system FAT32 has a limit on the size of a single file in 4 GB, which makes it unsuitable for high-quality film storage (4K HDR). For viewing heavy files, it is recommended to format the drive in NTFS Xiaomi TVs, as a rule, work correctly with the NTFS, Allows you to read large files. If you connect the disk, the TV offers to format it, make sure that it does not have important data, as everything will be deleted. Once connected, the path to the files is usually in the Media section or through the file manager. A more advanced way to organize a media library is the use of technology. DLNA protocol SMB. This allows you to stream the video directly from your computer or NAS-You need to share your movie folder on your PC, and you need to use a client app on your TV, for example, the same one. VLC X-plore file manager. โš ๏ธ Attention: When reproducing 4K-Video with a high bitrate (more than 80 Mbps) over Wi-Fi can occur slowdown. For stable operation, it is recommended to use an Ethernet cable connection or Wi-Fi at 5 GHz. USB-port also matters. On some models of TV ports USB 2.0 may not be able to handle the superheavy data stream 4K-In such cases, even a compatible codec can be played with jerks. You can check the specification of the ports in the instructions for a particular Mi model. TV. ๐Ÿ’กFile system NTFS It is the best choice for external drives with high-resolution movies, as it removes the 4 GB limit on file size. Solving playback and codec problems If you are faced with a situation where Xiaomi TV does not play video, the first step should be diagnostics. Try running the file on another device or through another player on the TV itself. Often, the problem is solved by a simple installation. VLC Or Kodi, which takes over the decoding, and in cases where the video slows down or twitches, try to lower the quality of the source or convert the file. The free HandBrake program is great for converting on a computer, and it allows you to transcode video into a compatible format. H.264 or H.265 You can choose the settings that are guaranteed to work on Xiaomi TVs, for example, you can select the profile "Fast". 1080p30ยป or 4K30ยป. It is also worth checking the image and sound settings. Sometimes enabling certain image enhancement modes (such as Motion Flow or noise cancellation) puts additional strain on the processor, which, combined with a heavy video file, leads to a drop. FPS. Try turning off all the "improvers" in the image menu and switching the sound mode to "Standard" or "Passthrough" if you use an external speaker system. Remember to update the TV firmware. MIUI for TV New versions of codecs and compatibility errors are often found. You can check for updates through the Settings menu. โ†’ On TV. โ†’ System update. Why can't the TV see the files on the flash drive? Most often it's in the file system, if the flash drive is formatted in exFAT or NTFS, TV does not read it, perhaps the drive has a volume of more than 2 TB (required) GPT Markup that the old TVs don't understand, or the file system is corrupted. FAT32 (For files up to 4GB, or check the disk for errors on a PC. Can you install codecs separately, like on a computer? Classically, like Windows (downloaded the K-Lite codec package and installed it), on Android TV It's not possible, but many players (VLC, MX Player) have built-in codec libraries or allow you to connect them as a separate plugin (for example, for the user to use the codecs. MX Player), which solves the problem of lack of support for formats system. Does Xiaomi support the format? MKV - Yeah, the format. MKV It's very well supported. It's built-in, it can display soft subtitles (SRT, ASS), If the subtitles don't show up or square, you'd better use a third-party player where you can manually select the font and encoding of the text. What is the maximum bitrate of video Xiaomi supports? TV? Officially, most models support decoding video with bitrate to 100-120 Mbps: Files with higher bitrates (such as original Blu-ray rips) may play unstablely, especially if they are on the Internet. USB-It's a low-speed drive. What do you do if you have video but no audio? It's a classic sign of not having an audio codec license? DTS. Solution: establish VLC Player (it often has its own codecs) or convert the audio track of a file to a AAC/AC3 on a computer before recording on a flash drive.
