It's not the cost... I purchased the plex app. That is what is needed for my use. I have also purchased the a avia app as well. I don't want to pay four bucks a month for a service that I rarely use. Four kids in college and all that.
Quite Understandable....I'm not even sure you can buy just one month as I thought the Sub Options were a Year and Lifetime.
I understand why CCast support is PlexPass only at this point. If you're a regular visitor to the Plex Forums you would see a myriad of issues being reported regarding the transcoding and specifically surround Audio. This is on top of the usual problems we talk about here such as loss of control, Network, Router and Connection issues.
Right now the PlexPass users are sort of acting as the Beta Testers for this since they are the most familiar with Plex and it's workings.
To open it up to the Public right now would probably overwhelm the support forum rehashing the Bugs they already know about and add the reports of things that are not broken just because the user didn't know there is a setting in Plex set wrong they didn't know exists.
I would guess that when the Transcoder is running perfectly you might see CCast support go Public.
But they may also wait until they finish their Music and Picture support which at this point does not exist at all.
aVia does work provided your library doesn't need transcoding but if you do then it might be worth paying for the PlexPass at least until they release it publicly.
Plex right now is the only system that works exactly as Google intended it to when they developed the CCast.
Mobile App tells the CCast to load a player app and play a stream direct from a server without needing the device that launched it once it starts.
Plex is the only system that transcodes local files for playback as RealPlayer requires you to upload to their cloud to get a transcoded stream back.
Perhaps the announcement about the 10 Apps with CCast support being added was a bit of stretching the truth for Christmas Shopping Marketing Purposes...
Cause lets be honest none of the options for Local Content are perfected or issue free. aVia has had at least 10 Updates since the announcement maybe even more....
Most of the work on the Plex side has been done to the server side because I haven't seen any updates to the Android apps itself, certainly not as many as the aVia Player has....
All the Local playback App options do the job better than CCast did before they were released...
But thats about all you can really say about them. They are all still learning how to crawl at this point and none are what I would call a perfected and Mature option that does everything we expect they should yet.
It's going to take time...What CCast does it much more complicated than what Miracast, Roku and Airplay do.
