What file formats support Xiaomi TVs: video, audio, images

Xiaomi TVs (Mi series) TV, Redmi TV, Xiaomi TV A and others) are positioned as universal multimedia centres, but not all file formats are reproduced correctly. If you plug in a flash drive or an external hard drive and the video doesn't work, the audio plays without sound, or the photos don't open, the problem is probably codecs or firmware limitations:

✅ Official formats that support all modern Xiaomi models TV (2018–2026 issue).

✅ Hidden Limits: Why Some.mkv or.flac Files Are Not Playable.

✅ How to get around restrictions without buying a new TV – from converting to alternative players.

✅ Compatibility table by model: from budget Redmi TV A55 before the flagship Xiaomi TV Q2 75".

Even if your TV is theoretically format-supporting (e.g, HEVC), This does not guarantee smooth reproduction. 4K HDR It depends on the iron platform (Amlogic or MediaTek processor) and the firmware version. MIUI TV.

1. Video formats: what Xiaomi is playing TV convertible

Xiaomi TVs are built on the basis of Android TV (or its lightweight version MIUI TV), That's why they support most of the popular containers:

• 📺 Containers:.mp4,.mkv,.ts,.avi,.mov,.flv,.webm,.3gp. But the files.m2ts (Blu-rays are often played without sound due to codec issues DTS-HD.

• 🚫 Not supported: VC-1 (It is used in some Blu-rays), MPEG-1, DivX 3.11 and video with variable bitrate (VBR) above 40 Mbps.

Most problems arise with.mkv files, where video is playing and no sound is being played, and the reason is that there is no decoding license. DTS The solution is to either convert the audio track to AAC/AC3, Or use an external player (more on below).

⚠️ Note: Xiaomi TVs on the Amlogic processor S905 (Like Mi. TV 4S 55") non-replicate 10-bit-bit HEVC higher-resolution 3840×2160 bitrate >50 Mbps: The file will either slow down or not open at all.

If your model is not in the table, check the format support experimentally:

Download the test files from [demo-ufa.ru](https://demo-ufa.ru)

Put the flash drive in port. USB 2.0 (not 3.0!)

Open the built-in File Manager

Try to play the files one by one.

Write down which formats do not work.

For Android models TV 9 and below (e.g. Mi) TV 4A) The Reproduction Problem Is Relevant VP9 Profile 2 (used on YouTube) 4K). The solution is to update the firmware or use Smart YouTube TV.

5. How to Reproduce Incompatible Formats

If your TV doesn’t support the format you want, there are a few ways to get around the restriction:

🔄 Method 1: File conversion

Use the programs:

• 🖥️ HandBrake (for video) - Convert to H.264/AAC bitrate 20 Mbit/s.
• 🎵 Audacity (for audio) - convert FLAC into WAV or MP3 320 kbps.
• 📷 Adobe Lightroom (for photo) - export RAW into JPEG.

When converting videos for Xiaomi TV Recommended settings in HandBrake:

Format: MP4 (M4V)


Video codec: H.264 (x264)




Quality: RF 18–22 (or bitrate 10–15 Mbps)




Audio codec: AAC (160–192 kbps)




Resolution: not higher than 3840×2160 (if source 4K)

📺 Method 2: External players

Install from Google Play:

• 🎬 VLC for Android TV — supportive DTS, TrueHD, 10-bit HEVC.
• 🎵 MX Player (with Custom Codec) – best for.mkv.
• 📂 Kodi – universal media center with support for network folders (SMB, NFS).

• 🔗 AirScreen – for mirroring the screen from the phone (Miracast).

To set up Plex:

1. Install Plex Media Server on your PC.
2. Add the files to the library.
3. On the TV install Plex for Android TV.
4. In the server settings, enable Transcoding and limit the bitrate to 12 Mbit/s.

💡

If the TV doesn’t play the file, try the external player first (VLC/Kodi), And then convert. Often the problem is not the format, but bitrate or codec.

6. Frequent problems and solutions

Even if the format is supported, there can be errors.

🔴 Problem: Video slows down or is jerking

Causes and solutions:
