[REQUIRED] Question
Is there a time frame/plan for adding CAS support? With Widevine CAS announced, it makes sense to provide an implementation for CA systems in general. Android already exposes all the necessary APIs since API lvl 26.
This issue does not seem to follow the issue template. Make sure you provide all the required information.
Hi @jonasevcik, we are working on this. I can't provide an ETA yet, though.
Hi @AquilesCanta / @ojw28. Two months later, is there an ETA for Widevine CAS support?
Not yet, sorry. I'd be interested in learning how you plan to use MediaCAS:
- Do you know what codecs you'll be using?
- Do you have protected content? How do you (plan to, if you don't have) produce protected content? Which parts of the stream are / will be encrypted?
- How will you/do you stream protected content? OTT?
We need a solution to the following use case, which by my understanding is the point of Widevine CAS.
The potential customer already has a legacy CA-protected stream. It is broadcast to existing set-top-boxes using UDP multicast. As a legacy CA system, the stream has ECMs in it (so far, from their existing CA provider -- our Widevine-based ECMs will be added too). They want to start using Android TV instead (or in addition) to the legacy STBs.
The content is being generated by an existing encoder and streamed via UDP to the network.
So, if I understand correctly, ExoPlayer would have to join the multicast (which it can already do for clear streams) and use MediaCas to descramble the stream.
Widevine CAS is now GA and the integration docs are published:
Is there a plan to implement CAS support in ExoPlayer in the near future?
EDIT: access to these docs is restricted to CWIP licensees.
I don't have access to those docs. If you can grant that, that would be great. I will also try to contact widevine on my side.
Sorry, I was under the impression that they don't need authorization because the links are published in the public-facing page https://www.widevine.com/news. I guess I can only access them because I'm logged in to my CWIP-enabled Google account. Unfortunately this means that I can't upload them here because it will probably violate the CWIP terms. However, I'm pretty sure that since they put the links on the public site, they also intended to remove the required authorization.
EDIT: I see they've attached the following text to the announcement:
Note: Access to Widevine documentation is now restricted to licensees. If you are unable to view the document links, please contact us.
Which means I'm definitely not allowed to share these docs, and you will have to get them from Widevine.
Hello all,
It would be good to know what the immediate plans are from the dev team here. This feature would be quite useful / important in enabling operators to switch from legacy systems to AndroidTV
We don't have any plans for this for at least the first three months of 2020, sorry.
We don't have any time allocated to this in Q2, sorry. I doubt we'll have time in Q3 either.
@tonihei CAS v1 is probably no longer relevant, but it might be worth asking the TV team what we can do on our side. You can find points of contact in [internal ref: b/239731089].
Does ExoPlayer not support MediaCas? Is there a guide available on how to play CAS-encrypted files using MediaCas in ExoPlayer?
