| Common abilities | |
| Packet filtering | Each stream has three-state mode selector:
|
| Open multi-segment streams | The Advanced tab of the Open File dialog accepts an init segment plus its media segments (DASH / HLS / CMAF, or a directory of MPEG-TS chunks) and analyzes them as a single session with lazy segment loading |
| Open from URL | The URL tab points the analyzer at a single remote file. Requires CORS and a Content-Length header on the server. |
- The processing of the file is done locally in your browser, using WebAssembly code. No file content is sent to our servers
- We still send some telemetry to help us understand the problem. Open browser's console to check the messages sent to our server.
