Why Xiaomi doesn’t play video: 7 main reasons

A message about an unsupported or corrupted file can appear even from a video that used to open without problems, here are the key reasons that are characteristic of Xiaomi devices:

• 📱 Xiaomi smartphones based on MediaTek (for example, Redmi) 10C) They often don’t support rare codecs. AV1 or VP9 Profile 2, while models on Snapdragon (Xiaomi) 12T) do better.
• 🔄 Failure to record: If the video was captured in poor memory conditions (e.g., with a 90-plus full storage device%+), The file system may not have time to close the file correctly.
• 🗃️ File system damage: More common on devices with eMMC 5.1 (e.g. Poco) X3 Pro), where a sharp power outage damages the metadata files.
• 🔒 Limitations MIUI. In the firmware MIUI 13/14 There is a bug: after updating, the multimedia player settings are reset, and it ceases to recognize some formats.
• 🦠 Viral infection. Rarely, but there are viruses that replace video file titles (for example, the Android.Triada Trojan, discovered in 2022 on some Xiaomi).
• 🔌 Problems with the drive. on smartphones with a hybrid slot (Redmi Note 11 Pro)+) MicroSD cards often fall off during writing, which leads to a file break.

Before you start restoring, check if the video is playing on other devices. Connect your smartphone to your PC and try opening the file via Windows Media Player or PotPlayer. If the error persists, the problem is in the file itself. If the video opens, the settings or software of your Xiaomi are to blame.

Diagnostics of the problem: how to determine the cause of the failure

So, to avoid wasting time on useless actions, first determine which component is to blame for the error.

1. Check the file extension. Sometimes the video is saved with the wrong extension (e.g..mp4 instead of.mov). See the file properties through Files → More → Information.
2. Test another player. Install MX Player or VLC from Google Play — they support more codecs than the standard Mi Video.
3. Check file integrity. Connect your smartphone to your PC and start the command: ffmpeg -v error -i "path to file.mp4" -f null - If there are lines with [error] in the output, the file is corrupted.
4. Error log analysis. On Xiaomi, turn on Developer Mode (7 taps on the MIUI version in settings), then check logs through Settings → Additional → Journals → media.log.

If you have errors in your logs like OMX.CodecUnsupportedError or E/MediaExtractor: unsupported format, the problem is the codec. If there are no errors, but the video is not played, the file metadata (which can be restored by special programs) is to blame.

💡

On Xiaomi with a MediaTek processor (like Redmi 9A), some codecs are locked at the driver level. Check support via adb shell dumpsys media.codec.list
