How it works
Complete the job in three clear steps
- Choose a media file from this device.

- Copy or download the JSON report before closing the page.
Private Lucaden media inspector
Media Codec Compatibility Checker
Identify a file's real container and codecs, then ask the current browser whether it reports native playback support.
Free to use MediaInfo WebAssembly reads the selected file in local chunks. The file and extracted metadata are not uploaded to Lucaden.

Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
What this Lucaden tool does
Lucaden combines MediaInfo's stream detection with the browser's canPlayType result. The answer applies to this browser and device, not every player or platform.
The same local analyzer powers each focused route, while the workspace highlights the fields relevant to that task.

Questions
About this tool
Is a Probably result a guarantee?
No. Browser APIs do not test every profile, level, hardware decoder, damaged frame, or destination platform.
Why can a file fail even when its extension looks right?
Containers can hold codecs or profiles the browser does not support, and extensions can be renamed without changing the file.
Open-source foundations
Built transparently
Lucaden documents its standards sources, architectural references, and permissive runtime dependencies while keeping this workspace consistent with the Lucaden interface.
