Sorry，I’ve confused two concepts. What I want to express is that,
Firstly, the browser may be able to make use of “native” codec APIs of the “hard” device(e.g. mobile phone), and include the “native” codecs in the SDP O/A messages.
In addition, for application flexibility, the browser should provide codec capability APIs to developers. Then,  the developers can choose proper codecs according to the specific scenario.

So there should be two APIs. The first is provide by the device and used by the browser. The second is provided by the browser and used by the developer.

Best Regards,
Lijing

I fully agree with the idea to " use existing "native" codecs ".

In addition, from a web developer's perspective, in order to make use of the "native" codecs, the browser should provide codec APIs to open the local codec capabilities of the device to applications and developers. It really make sense.

I don't understand what this means.
