Supported video formats on Xiaomi smartphones: full guide 2026

Xiaomi Android smartphones are famous for their versatility, but when it comes to video playback, users often face unexpected limitations: Did you download a high-bitrate.mkv movie and the player gives you an error? Or did the camera record a video in HEVC that doesn't open on the old device? The problem is not the "curve" of the firmware, but the technical limitations of the hardware and software.

In this article, we’ll break down all the video formats that Xiaomi officially supports (including the Redmi, POCO and Mi/Xiaomi 14 flagship series), learn which codecs work out of the box, how to get around the restrictions through third-party players, and why even the powerful Snapdragon 8 Gen 3 may not be able to handle video in AV1.

Official support for video formats in MIUI

MIUI firmware (even in the latest version of MIUI 15) is based on the standard Android Media Framework, but has its own nuances. By default, the system supports the following containers and codecs:

• 📦 Containers:.mp4,.m4v,.3gp,.3g2,.webm,.mkv (partially),.ts,.avi (with limitations).
• 🎞️ Video codecs: H.264 (AVC), H.265 (HEVC), MPEG-4, VP8, VP9 (Starting with Android 9).
• 🔊 Audio codecs in video: AAC, MP3, Vorbis, Opus (in.webm), AC-3 (Only in some models).

It’s important to understand that support for MKV and AVI on Xiaomi smartphones is often limited to hardware decoding. For example, a.mkv file with HEVC 10-bit video and DTS-HD sound can play with jerks or not open at all — even if the player shows it on the list, due to the lack of licenses for some codecs in stock firmware.

To check if your device supports a specific format, go to Settings → About Phone → MIUI version and compare it to the table below. or use the AIDA64 app (Multimedia → Codecs section).

Table of format compatibility by Xiaomi models

Below are the data for popular Xiaomi devices (relevant to MIUI 14/15 firmware based on Android 13/14). Note: support for AV1 and 10-bit HDR depends on the processor (for example, Snapdragon 8+ Gen 1 decodes AV1 software, and Dimensity 9000+ – hardware).

⚠️ Note: On devices with MediaTek Helio processors (e.g. Redmi) 9A or POCO M4 Pro) hardware decoding HEVC In such cases, the video is played using the CPU, which leads to overheating and rapid discharge of the battery.

💡

If your video isn’t playing, try converting it to H.264 with a bitrate of no more than 10 Mbps – this is guaranteed to work on any Xiaomi smartphone.

Why do some formats not work out of the box?

The reasons for the limitations lie in three key factors:

1. Hardware limitations: Qualcomm and MediaTek chips have different decoding units, for example, the Snapdragon 7xx does not support AV1 at the hardware level, and the Dimensity 1200 only partially.
2. License Restrictions: DTS, Dolby Vision, or AC-4 codecs require payment for licenses that Xiaomi does not always include in stock firmware.
3. MIUI restrictions: In some regions (e.g. Europe), codecs for MKV with multichannel sound have been removed from firmware due to patent disputes.

For example, if you downloaded a movie in an MKV with a DTS-HD MA 7.1 soundtrack, the Mi Video stock player will either play the video without sound or it will give you an error, the decision is to use the MX Player with additional codecs or convert the audio to AAC.

Another common case is VP9 Profile 2 (10/12-bit HDR) video, which can be played with artifacts on Adreno 6xx devices (e.g., Snapdragon 732G in POCO X3), and is solved by transcoding to H.265 10-bit.

How to reproduce incompatible formats?

If your video doesn’t open in a stock player, there are three reliable ways to do this:

1. Install the player with support for additional codecs

• 🎬 MX Player (with Custom Codec package) DTS/AC3).
• 📺 VLC (supportive AV1, but without hardware acceleration).
• 🖥️ Kodi (for advanced users, supports external subtitles).

⚠️ Attention: B MX Player after installing Custom Codec go to Settings → decoder → Custom codec and select SW+ (programmatic + Otherwise, the sound may not be available.

2 Convert the video to a compatible format

Use HandBrake (PC) or Video Converter (Android) with settings:

• 📌 Format: MP4 or MKV (if necessary H.265).
• 📌 Video codec: H.264 (for maximum compatibility) or H.265 (save space).
• 📌 Audio codec: AAC (universally) or Opus (for.webm).
• 📌 Bitrate: no higher than 15 Mbps for 1080p and 30 Mbps for 4K.

Make sure the container format is MP4 or MKV

Check the video codec (H.264/H.265)

Replace audio with AAC or Opus

Reduce bitrate to 10-15 Mbps for 1080p

Disable DTS/Dolby if the player does not support

-->

3.Use streaming (DLNA/UPnP)

If the video is on a PC or NAS, set up streaming via:

• 🖥️ Plex (transcodes on the fly for compatibility).
• 📡 BubbleUPnP (for local area network).
• 🌐 Jellyfin (Free Alternative to Plex).

✅ Key conclusion: 90% of cases are sufficient to install MX Player with Custom Codec. Conversion is only required for unique formats (e.g. ProRes or ProRes). AV1 12-bit).

💡

Mi Video does not support DTS or Dolby TrueHD – use MX Player or VLC.

Frequent problems and solutions

Even if the format is officially supported, there may be errors.

1.The video is played without sound

Reason: audio codec is not supported (e.g. DTS or E-AC-3).

• 🔇 Recode sound into AAC via FFmpeg:
• 🔇 V MX Player selects decoder SW (software-only).

2.The video slows down or jerks off.

Causes and solutions:

• 🐢 High bitrate: lower to 10-15 Mbps for 1080p.
• 🔥 CPU overheating: Close background applications or use a cooling stand.
• 📉 10-bit HDR on a weak chip: convert to 8-bit SDR.

3. Black screen when playing

Most commonly found with HEVC 10-bit files on Mali-G57 devices (e.g. Redmi Note 11).

• 🖼️ transcoded into H.264 or HEVC 8-bit.
• 🖼️ V VLC enable hardware acceleration in the settings.

💡 Useful tip: If YouTube videos are not played, download them in.webm format with codec VP9 — It is better optimized for mobile than H.264.

How to check format support on your Xiaomi?

To find out exactly what codecs your device supports, follow the following steps:

1. Install the AIDA64 app from Google Play.
2. Go to the Multimedia section. → Codecs.
3. Check the lines: H.265 decoder is HEVC support. VP9 decoder is VP9 support (should be yes). AV1 decoder is if no, AV1 will not play without lags.

An alternative method is to use the adb command:

adb shell dumpsys media.codec.list

In the output, look for lines from OMX.qcom.video.decoder.hevc (for HEVC) or OMX.google.vp9.decoder (for VP9).

⚠️ Note: On some devices (e.g. Redmi) 9C) support HEVC It may be listed as yes, but in practice, the video will be played with artifacts due to a weak Helio processor. G35.
