Corresponding MediaNet adapter video support PR: prebid/Prebid.js#5482

[Fawke]

Hi @bretg,

I was reviewing the corresponding PR for Prebid.js, and according to the blogpost for Prebidv4.0, we now need adapter to pass video params under mediaTypes.video object instead of bidder.params. Is this something we are enforcing now, or is it for a future major release? I gathered that we are enforcing it from now onwards!

@c3p-0 - @Fawke is right - video parameters must come from mediatypes.video. It's ok to accept them on BOTH mediatypes.video AND bidder params.

Thanks @bretg , So no action is required from my side.

[Fawke]

@c3p-0, I think you need to accept video params from either location. bidder.params (which you are currently doing now)or mediaTypes.video. It's encouraged that you do it from the latter. I don't know whether this'll require a docs change or not.

As suggested by @Fawke we are consuming video from both bidder.params and mediaTypes.video and giving precedence to mediaTypes.video.
@bretg Please let me know If this PR is looking good or not.

@c3p-0 Bret is on vacation. It looks like you've mentioned support for mediaTypes.video and included it in your example. So I'm going to go ahead and merge this; if anyone thinks additional updates are required we can make them later.
