VLC provides tools for viewing statistical information about a live stream. This includes both metadata and codec information within the source video itself, such as frames-per-second or audio codec specification, as well as details of the live stream fidelity, such as current video bitrate or the number of dropped frames.
Video codec information is created at the source and is not introduced or affected by the Zixi transport protocol. This information can help ensure the source content adheres to the desired video and audio specification.
To view video codec information:
- In VLC's Main Menu, click Tools menu and select CODEC Information.
A window appears displaying a dropdown for each elementary stream and additional data by type:
| Data Type | Details |
|---|
| Video | Original ID Codec Resolution (Source) Resolution (Display) Decoded Format |
| Audio | Original ID Codec Language Channels Sample rate |
| Subtitle | Codec Description |
Zixi will pass through any metadata found in the source, including custom metadata that was injected into the source stream wrapper.
To view custom metadata:
- In VLC's Main Menu, click Tools menu and select Media Information.
A window appears displaying current media information. - Click the Metadata tab.
VLC’s statistical information provides live data on end-to-end stream fidelity as well as the QoS between your VLC player and the Zixi broadcaster from which VLC is pulling the stream.
To view statistics:
- In VLC's Main Menu, click Tools menu and select Media Information.
