Just (Video) Player

Android video player based on ExoPlayer.

It uses ExoPlayer's extension-ffmpeg with all its audio formats enabled (it can handle even special formats like AC3, EAC3, DTS, DTS HD, TrueHD etc.).

It properly synces audio with video track when using Bluetooth earphones/speaker. (I was not able to find any other nice ExoPlayer based video player so I created this one.)

Supported formats

  • Audio: Vorbis, Opus, FLAC, ALAC, PCM/WAVE (μ-law, A-law), MP1, MP2, MP3, AMR (NB, WB), AAC (LC, ELD, HE; xHE on Android 9+), AC-3, E-AC-3, DTS, DTS-HD, TrueHD
  • Video: H.263, H.264 AVC (Baseline Profile; Main Profile on Android 6+), H.265 HEVC, MPEG-4 SP, VP8, VP9, AV1
  • Containers: MP4, MOV, WebM, MKV, Ogg, MPEG-TS, MPEG-PS, FLV
  • Subtitles: SRT, SSA, ASS, TTML, VTT

HDR (HDR10+ and Dolby Vision) video playback on compatible/supported hardware.


  • Audio/subtitle track selection
  • Playback speed control
  • Horizontal swipe to quickly seek
  • Vertical swipe to change brightness (left) / volume (right)
  • PiP (Picture in Picture) on Android 8 or higher
  • Resize (fit/crop)
  • Volume boost
  • No ads, tracking or even the Internet permission

To load an external (non-embedded) subtitles, long press the file open action in the bottom bar.

WRITE_SETTINGS ("Modify system settings") permission: When the system file chooser is opened, it will always use current system orientation, even if the Player app sets its own. Granting this permission via adb (adb shell pm grant com.brouken.player android.permission.WRITE_SETTINGS) or App info screen will allow this app to temporarily enable Auto-rotate to at least partially mitigate this imperfection.

What to do if Bluetooth audio is not in sync with video?

Just pause and resume playback once again.

How do I change subtitle font, size or color?

If you enable Caption preferences on your device, you will be able to override the default subtitle style of the Player and fully customize subtitle style.

Are there any media formats it CANNOT play?

Unfortunately, upstream ExoPlayer doesn't handle some older formats like AVI container, WMV or Theora.

Just Player focuses on playing videos so audio only playback isn't officialy supported.

Can I play videos that are not stored on the device?

Videos in cloud storages - YES

Official cloud storage clients (like Dropbox or Google Drive) usually implement all the technical requirements so storage can be browsed when opening video in Just Player.

Video streams on the Internet - Yes (since v0.16-online)

Basic support for playing streaming videos is in the -online version, available only in releases on Github (F-Droid and Google Play are staying on the -offline build).

Videos in network storages (Samba, WebDAV, SCP etc.) - YES (since v0.16-online)

You can open videos on network storages using file managers such as Solid Explorer, Total Commander or Ghost Commander.

Other open source Android video players

Here's a comparison table presenting all available and significant open source video players for Android I was able to find. Just Player is something like 80% feature complete. It will probably never have dozens of options or some rich media library UI. It will never truly compete with feature rich VLC. It just attempts to provide functional feature set and motive others to create greater players based on amazing ExoPlayer.
