**Header:** `ClikaRT/io/io.h`

A video stream's static geometry / timing, read from its header. Named [`VideoInfo`](./VideoInfo.md) (NOT `VideoMetadata`, which is the processor's 3-field timing struct) since it is a superset: geometry + codec identity too.

## Data members

### total\_num\_frames {#total_num_frames}

<div class="api-signature">

`std::int64_t` **`total_num_frames`** `= 0`

</div>

Frame count. Known when the clip opens for every container the backend can probe: read from the header, derived from the duration, or counted off the packets. Where a backend genuinely cannot establish it, the count reads 0 and the index calls refuse an out-of-range frame by name rather than answering with a different frame.
