## Details

Adding `&meshcastcodec` to the publisher's side together with [`&meshcast`](https://docs.vdo.ninja/advanced-settings/meshcast-parameters/and-meshcast) gives the option to change the publishing codec for Meshcast.

Example usage: `https://vdo.ninja/?meshcast&meshcastcodec=vp9`

There's 4 codec options currently, including the default option:

* The unspecified default, which is software h264.&#x20;
* There's also `h264`, which is what the browser then sets. This could include hardware encoding, but that will not work with Firefox or Safari viewers then.&#x20;
* `vp8` is pretty compatible, so if the default codec doesn't work, you can try that.&#x20;
* `vp9` is also available, which has better compression/quality, but not fully compatible with all devices.&#x20;
* av1 and svc are not yet supported, but that is planned at some point.
