Official support for Xiaomi formats TV: What the manufacturer says
According to Xiaomi’s documentation, the brand’s TVs support the majority of popular video formats, but with reservations.
- 📺 Budget series (Redmi Smart) TV, Mi TV 4A/4S) — Basic support, resolution and codec restrictions.
- 💎 Mid-segment (Mi) TV 5/5X, Mi TV P1) — Expanded opportunities, including HDR10+ Dolby Vision and.
- 🚀 Flagships (Mi) TV Q1/Q2, Mi TV Master – Maximum compatibility, support AV1, 8K and advanced audio formats.
The official list of supported containers (file extensions) includes:
- 🎬 .mp4 (H.264/H.265), .mkv (Matroska), .mov (QuickTime)
- 📼.avi (DivX/Xvid),.ts/.m2ts (video-streaming)
- 🎵.flv,.wmv (limited support, artifacts possible)
But there is a caveat: the container itself (e.g.,.mkv) can contain video and audio in different codecs. Xiaomi TV will play the file only if both components (video) + sound compatible. For example,.mkv with video H.265 sound-and-sound DTS-HD It will not be played on Redmi Smart. TV, Because this model does not support DTS-HD.
⚠️ Attention: Firmware based on Android TV 9.0 and below (e.g. Mi) TV 4A 2018 not supported AV1 and VP9 Profile 2. Software update doesn't add this feature - hardware support required.
Video Codec Support: What Will Play Your Xiaomi? TV
The video codec determines how the video stream is compressed, and it affects not only compatibility, but also the load on the TV processor. Below is the support table for the main codecs depending on the model:

| H.265 (HEVC) | ✅ Do 4K@30fps | ✅ Do 4K@60fps | ✅ Do 8K@60fps | It requires hardware decoding. 4A Possible lags with high bitrate. |
| VP9 | ✅ Do 4K@30fps(Profile 0) | ✅ Do 4K@60fps(Profile 2) | ✅ Do 8K@30fps | VP9 Profile 2 (10-bit HDR) It does not work on budget models. |
| AV1 | ❌ No. | ⚠️ Partially (Mi only) TV 5X 2022+) | ✅ Full support | Requires Android TV 11+ and hardware acceleration. |
| MPEG-2 | ✅ Do 1080p | ✅ Do 4K | ✅ Do 4K | Used in DVD digitally. |
Xiaomi TVs based on Amlogic processors S905 (Like Mi. TV 4A 32) do not support hardware decoding VP9 and HEVC 10-bit. When you try to play this video, you will have a high download percentage. CPU and “retardation».
If your file is not played, check the codec using MediaInfo (free for the user) Windows/macOS). For example, the video in AV1 It will not work on the Redmi Smart. TV X50, But it'll be reproduced on Mi. TV Q2 75".
Audio formats: why there is no sound, but the video is
A common problem is that video plays but no sound, and that's because of an incompatible audio codec. TV Supports the following sound formats:
- 🔊 AAC — The basic format works on all models.
- 🎶 MP3, WMA — Compatible but without multi-channel sound support.
- 🎧 Dolby Digital (AC-3) — It is supported by all models except Redmi Smart. TV 32".
- 💥 DTS/DTS-HD — only on flagships (Mi) TV Q1/Q2 newer).
- 🚫 TrueHD, E-AC-3 (Dolby Digital Plus – no model supported.
If your.mkv file contains the sound coded in DTS-HD MA, And the TV is Mi. TV 4S, There will be no sound:
- Recode audio into AAC or AC-3 (Use FFmpeg or HandBrake).
- Connect an external sound system (such as a soundbar) with support DTS through HDMI ARC.
- Use a Plex or Kodi media player that transcodes sound on the fly.
⚠️ Attention: On Android TVs TV 9.0 when playing files with DTS through USB You may have an error, "Audio codec is not supported," even if the model is officially compatible, and then you may need to update your firmware or use it. DLNA.
Resolution and frame rate: what are the limitations of Xiaomi TV
Even if the codec is supported, the TV may not play video due to incompatible resolution or frame rate.
- 📏 Mi TV 4A/4S: maximum 3840×2160 (4K) upon 30 FPS. Primary 60 FPS Possible drop in staffing.
- 🖥️ Mi TV 5/5X: 4K@60fps for H.264/H.265, 1440p@120fps game console.
- 🎮 Mi TV Q1/Q2: 8K@30fps (only HDMI 2.1), 4K@120fps play-off.
Special attention should be paid to non-standard permits:
- Permission video 2560×1080 (21:9) will be cut or stretched.
- Files from 10-bit colour (e.g, HEVC 10-bit) They will not be reproduced on budget models.
- Variable frame rate video (VFR) It can be “slow down” on Android TV 9.0.
To check the permission and FPS Use the command in FFprobe (part of FFmpeg):
ffprobe -v error -select_streams v:0 -show_entries stream=width,height,r_frame_rate -of csv=s=x:p=0 input.mp4💡
If you're Xiaomi. TV reproduce 4K-YouTube video, check the settings HDMI: Go to Settings. → Display and sound → HDMI → Regime. HDMI Choose the improved (Enhanced).
How to Check File Compatibility Before Viewing
Before copying the video to a flash drive or running through DLNA, Check its compatibility. Here's the step-by-step instruction:

⚠️ Note: When reproducing through USB Avoid files larger than 4GB FAT32 (File system restriction: Use exFAT or break down video into parts.
Frequent problems and solutions
Even if the format is supported, there may be errors, and let's look at the typical cases and how to fix them:
- 🔄 Video slows or breaks: Reason: high bitrate or incompatible codec Solution: recode video with a bitrate of no more than 30 Mbit / s for 4K.
- 🔇 No sound, but video is coming: Reason: audio codec DTS-HD TrueHD: Solution: Convert sound to AAC Or connect an external receiver.
- 🖼️ Black screen when playing: Reason: Incompatible resolution (e.g., incompatible resolution, 10-bit HDR Solution: change the color profile to 8-bit or turn it off. HDR TV settings.
- 📵 File won't open with USB: Reason: File system NTFS Solution: format the flash drive in exFAT or check the file on another device.
If the problem persists, try resetting the media player settings:
- Go to Settings → Applications → Application Management.
- Find the Media Player (or Gallery) app.
- Select Warehouse. → Clear the data.
