How to extend HTTPLoader?

[snowinszu]

My code is like below:

function CustomLoader() {
    const parent = this.parent;
    function load(config) {
        parent.load(config);
    }

    function abort() {}

    return {
        load: load,
        abort: abort
    }
}
player.extend("HTTPLoader", CustomLoader);

But it got recursive call, any help?

What do you mean exactly by " it got recursive call"? Please provide more information on what you are seeing and what you expect to see.

I want to hook the HTTPLoader to add some custom logic, in my custom loader it can call the original HTTPLoader function like .load() and .abort()

I dont think it is possible that way. From the API defintion

If you set override to true any public method or property in your custom object will
override the dash.js parent object's property(ies) and will be used instead but the
dash.js parent module will still be created.

This means you are recursively calling load. I understand your use case but the current implementation is too limited to support this.

As a workaround you might be able to use this for v4 https://reference.dashif.org/dash.js/v4_nightly/samples/advanced/extend.html or this for v5 https://reference.dashif.org/dash.js/nightly/samples/network-interceptor/index.html to change the requests.
