Why not frameId like in RTCEncodedVideoFrameMetadata ?

As noted in the Dependency Descriptor specification section A.8.3, frame_number is not the same as FrameId.

dependencies in RTCEncodedVideoFrameMetadata is not defined but I'm assuming it is a sequence of frameId values. dependsOnIds is a sequence of frameNumber values (though it seems odd that frameNumber is an unsigned short and dependsOnIds is a sequence of unsigned long values).

Shouldn't it be names dependsOnFrameNumbers then?

Otherwise LGTM.
