Command Line Launch Options

Multiview for NDI supports the following command line options.

These are subject to change. We'll do our best to indicate if/when a command line parameter will be deprecated or removed.

"--blittype": Scaling mode override

Sets the upscale/downscale mode in the engine. By default, the engine uses nearest neighbor which will result in blocky upscaled images.

Accepted options:

• --blittype=fastest: The default, uses nearest neighbor.

• --blittype=plinearlut : Use linear interpolation. This uses parallel processing to speed up rendering.

• --blittype=linearlut: Use linear interpolation, single-threaded. Note this is much slower than nearest neighbor. This option is not recommended.

"--eemsec": Caption evaluation time override

Sets the wait time (in milliseconds) for caption expression evaluation. Defaults to 250 milliseconds (4 updates/second).

Since an update to an expression can cause captions to be re-rendered, we suggest keeping this number fairly high. 250 milliseconds tends to strike a good balance between reactivity and performance.

In the example below, expressions for captions will be re-evaluated every 500 milliseconds.
