Best Free Video Players for Terabox Files (MKV, AVI, HEVC)
Downloaded a Terabox video that won't play? These free video players open MKV, AVI, HEVC and almost any format on Android, iPhone, Windows and Mac.
Terabox stores whatever people upload, and a lot of long videos are shared as MKV, AVI or HEVC (H.265) files. The built-in video apps on phones and computers often can't play these, and show "unsupported format" or play sound without a picture. The fix is simple: use a better player. Every option below is free to download.
Why some videos won't play
A video file is a container (like MP4 or MKV) holding video and audio encoded with a codec (like H.264 or HEVC). Built-in players support the most common combination, MP4 with H.264, and little else. Players such as VLC include their own codecs, so they play nearly everything without extra setup.
Tip: you can also skip downloading entirely. The TeraLoader online player streams MKV and AVI through Terabox's own converted stream when one is available.
Android
- VLC for Android: open source and free with no ads. Plays almost every format, including MKV with subtitles. The best default choice.
- MX Player: popular and very capable, with gesture controls for brightness and volume. The free version shows ads.
iPhone and iPad
- VLC for Mobile: free, plays MKV and AVI that the Photos app can't. Open the file from the Files app and choose VLC with Share → Open in VLC.
- Infuse: a polished player with a free tier. Some advanced features need a paid upgrade.
Only MP4 and MOV files can be saved into the Photos app. Keep MKV files in the Files app and play them with VLC.
Windows
- VLC media player: the reliable all-rounder for any format.
- PotPlayer: lightweight, fast and very customisable, with excellent subtitle support.
- mpv: minimal and extremely efficient, great on older laptops, if you don't mind a very simple interface.
Windows' own Media Player can play HEVC only after installing Microsoft's HEVC extension. A third-party player is simpler.
Mac
- IINA: modern, native-feeling and free. Plays MKV, AVI and nearly everything else.
- VLC: works on Mac just as well as on Windows.

Frequently asked questions
Which player plays MKV files from Terabox?
VLC plays MKV on every device for free. On Mac, IINA is a great alternative; on Windows, PotPlayer.
Why is there sound but no picture?
Your player doesn't support the video codec (often HEVC/H.265). Open the file in VLC, which includes the codec.
