How to open .UVH files on Linux

To open .UVH files on Linux, check what your desktop thinks it is: view file properties and look for the MIME type (often expected to be video/vnd.dece.hd for .uvh in DECE/UltraViolet contexts).

Step-by-step instructions

  1. Check what your desktop thinks it is: view file properties and look for the MIME type (often expected to be video/vnd.dece.hd for .uvh in DECE/UltraViolet contexts).
  2. If it isn’t associated, set an application association manually (your desktop uses the shared-mime-info database rules for extension/MIME mapping).
  3. If playback fails, assume it is a streaming segment and try opening the accompanying manifest/playlist file from the same set, not the .uvh segment alone.

Common issues

The .uvh file won’t play in common media players

.uvh is commonly used as a DECE/UltraViolet HD streaming segment type (video/vnd.dece.hd), which many consumer players don’t support directly or don’t treat as a standalone video file.

  1. Look for companion streaming files from the same source (for example, a manifest/playlist) and open that instead of the .uvh segment.
  2. Try opening/importing the file in the same software/workflow that created or downloaded it.
  3. If you must make it playable elsewhere, use a trusted conversion/packaging workflow from the original toolchain rather than renaming the extension.

The file opens in the wrong app (or shows as an unknown file type)

Your system may not have an extension→MIME mapping or default app association for .uvh. On Linux desktops this typically depends on shared-mime-info mappings and your chosen default applications.

  1. Manually choose the app: Open with… and select the correct tool for the workflow that uses the file.
  2. On Linux, verify the system’s MIME handling/associations and set a default application for the detected MIME type (often video/vnd.dece.hd in DECE contexts).

You only received a single .uvh file and nothing else works

In streaming workflows, a single segment may be incomplete without the rest of the package (additional segments, manifest/playlist, metadata).

  1. Ask the sender/source for the complete set of files required by the stream (not just one .uvh).
  2. Re-download or re-export the content from the original source to ensure all related assets are included.

Renaming .uvh to .mp4 doesn’t help

Changing the filename extension doesn’t convert the underlying format, and players will still fail if the internal structure isn’t MP4 (or if the file is only a segment).

  1. Restore the original extension and handle it as a DECE/UltraViolet HD video segment.
  2. Convert/export using an appropriate tool in the original workflow, if conversion is necessary.

Security note

.uvh files are video data, but media parsers can have vulnerabilities; only open .uvh files from sources you trust, especially if your player or toolchain is outdated.
