You try to open a video on your Xiaomi, but instead of a picture, you see a black screen, an error โnot supportedโ or endless download? The problem is familiar to millions of users of Redmi, Poco and Mi smartphones โ from budget models to flagships. 80% of cases are not hardware malfunctions, but software conflicts that can be fixed on their own in 5-15 minutes.
This article doesnโt just list the standard tips like โreboot your phoneโ or โupdate your app.โ Weโve broken down 10 unique reasons why video might not play on Xiaomi, from hidden MIUI settings to how to work with HEVC/H.265 codecs. Weโve also prepared a format compatibility table for different models and a quick diagnostic checklist. If youโre a Redmi Note 12, Poco X5 or Mi 13 Ultra owner, hereโs the solution for your firmware.
1. Codec Problems: Why Xiaomi Doesn't Support Some Videos
The most common reason is the lack of hardware support for codecs. Xiaomi smartphones on Qualcomm Snapdragon processors (for example, Redmi Note 11 Pro+ with Snapdragon 695) often cannot decode HEVC (H.265) video with a resolution above 1080p if it is encoded with a 10-bit color depth. and devices on MediaTek (for example, Poco M5 with Helio G99) can slow down when playing AV1.
How do you check?
- ๐ Open file properties on PC: if the "Codecs" section is specified HEVC or AV1, That's the problem.
- ๐ฑ On your phone, install MediaInfo (available on Google Play) โ it will show you the exact video settings.
- โ๏ธ In the player settings (for example, MX Player: Enable the option โSoftware decodingโ (Settings) โ Decoder โ Use SW decoder).
Important for Xiaomi owners on MIUI 14+: the firmware defaults to some codecs because of licensing restrictions, even flagships like the Mi 13 Pro.
2. MIUI Conflicts: Hidden Settings That Block Video
MIUI is known for its โoptimizationsโ that sometimes break playback. For example, MIUI 13-14 has a hidden Video Toolbox feature that compels video compression in the background if power saving mode is turned on. And Redmi with MediaTek processors can trigger a hardware acceleration limit for third-party players.
What to do:
- Open Settings โ Battery and Performance โ Power Saving Mode and turn it off.
- Go to Settings โ Applications โ Application Management โ [Your Player] and allow auto-start and work in the background.
- For MIUI 14+: Enter the โVideo Toolboxโ settings in search and turn off video optimization.
โ ๏ธ Note: On some models (Poco) F4 GT, Redmi K50) post-update MIUI 14.0.4+ Dolby Vision is missing in the video. It's a firmware bug -- wait for the patch or roll back to the previous version.
Power saving mode disabled | Player auto-start | Video Toolbox | Updated Codecs in Google Play (for Android 10+)

3. Application problems: YouTube, MIUI Gallery and others
If the video is not played in only one app (for example, YouTube or the standard MIUI Gallery), the problem lies in the video itself.
- ๐ Cash of the application: YouTube after update to version 18.20+ The playback may be broken due to a damaged cache.
- ๐ ๏ธ Experimental functions: in MX Player included in Hardware+ Decoder conflicts with Adreno drivers (in smartphones on Snapdragon).
- ๐ฅ Loading restrictions: in the Gallery MIUI By default, downloading high-quality video on mobile Internet is disabled.
Decisions:
| Annex | Problem. | How to fix it |
|---|---|---|
| YouTube | Black screen when playing | Clear the cache (Settings โ Apps โ YouTube โ Storage โ Clear the cache) |
| MIUI Gallery | Video slows down or doesn't load | Enable โHigh Qualityโ in Gallery Settings โ View video |
| MX Player | Sound's there, no image. | Switch the decoder to Software in the settings |
| VLC | Video 'twitches' | Disable Hardware acceleration in Settings โ Video |

If the video in Telegram is not playing, try saving it to the device and then opening it through VLC. Often the problem is the compression that the messenger uses.
4. File system errors: corrupted video or SD-map
If the video is not played only from a memory card or after moving between folders, the file system is to blame. Xiaomi smartphones often conflict with exFAT (especially on Android 11-12), and when formatting in NTFS, read errors can occur.
- ๐ Wrong extraction SD-Cards (without Safe Retrieval).
- ๐ Abrupt power outage during recording/copying.
- ๐ฅ๏ธ Transfer files from the PC through MTP (Media Transfer Protocol).
How to restore:
- Connect. SD-map to PC and check for errors through chkdsk [disk letter]: /f (Windows).
- Reformat the card to FAT32 (if the volume is up to 32 GB) or exFAT (if more) using the official SD Card Formatter utility.
- For damaged videos, use FFmpeg with the command: ffmpeg -err_detect ignore_err -i input.mp4 -c copy output.mp4 (substitute input.mp4 and output.mp4 your files).
โ ๏ธ Attention: Xiaomi with Android 13+ and MIUI 14 has a bug: when connected SD-map OTG Videos may not open due to Scoped Storage limitations. Solution: copy the file to internal memory.
5.DRM and Licensing Limitations: Why Some Videos Are Blocked
Videos from services like Netflix, Disney+ or Amazon Prime may not play due to DRM (Digital Rights Management) issues. Xiaomi smartphones must support Widevine L1 for high-quality playback, but sometimes:
- ๐ Firmware knocks down Widevine certificates (often after root access or custom firmware).
- ๐ฑ The device is not certified by Google (checked in Google Play Protect).
- ๐ Update MIUI drop off the keys DRM.
How to check and correct:
- Install the DRM Info app from Google Play, and it will show you the Widevine level (should be L1).
- If level L3, reset via Settings โ Apps โ Google Play Services โ Storage โ Delete data.
- For rooted devices: Refuse the vendor and system section through Fastboot.
What if Widevine is lost after the update?
Hardware problems: when iron is to blame
If the video is not played in all applications, even after resetting the settings, hardware malfunctions are possible:
- ๐ฑ Problems with the graphics accelerator (for example, Adreno 640 in Snapdragon 865 can overheat and shut down).
- ๐ Memory controller malfunction (video โtwitchesโ or hangs on specific frames).
- ๐ Damage to the connector USB-C (If the problem is only when connecting to an external display).
Diagnosis:
- Run a graphics test through 3DMark or GFXBench โ if the FPS drops to 0, itโs the GPUโs fault.
- Check the temperature of the processor with AIDA64. If the Snapdragon heats up above 85ยฐC when playing, you need to replace the thermopast.
- Connect your phone to the Monitor/TV via HDMI (USB-C to HDMI adapter). If the video is playing normally on the external screen, the problem is with the display of the smartphone.

If the video isn't played in horizontal orientation only, check the gyroscope sensor. On Xiaomi, it can conflict with display drivers after the device falls.
7. Features of specific Xiaomi models
Some Xiaomi models have unique problems with video playback:
| Model | Problem. | Decision |
|---|---|---|
| Redmi Note 10 Pro | Green artifacts when playing HDR10+ | Disable HDR in screen settings or update firmware to MIUI 13.0.8+ |
| Poco F3 | Video in Telegram played without sound | Switch audio output to Stereo speakers in Settings โ Sound |
| Mi 11 Ultra | Brakes during 8K playback | Enable Game Turbo in the notification bar (paradoxically, but helps) |
| Redmi 9A | Does not support VP9 on YouTube | Use NewPipe or Vanced (alternative clients) |

On Xiaomi AMOLED-screens (e.g. Mi 11 Lite) may trigger a brightness limit when playing HDR. Turn off Adaptive Brightness in the Display Settings.
