What is a .OBU file?
OBU holds a raw AV1 video stream, the modern open video codec.
- Did you know
- AV1, released in 2018, is the royalty-free codec backed by Google, Netflix and others.
- AV1 was created by the Alliance for Open Media, a consortium founded in 2015, as a royalty-free successor to Google’s VP9 codec.
- An AV1 stream is packetised into Open Bitstream Units, each tagged with a type, which is what the OBU file extension refers to.

- Depth of analysis
- .OBU is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .OBU file
- Drag a .OBU file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
