Add support to launch and control the default receiver app

Might be interesting to see how this app launches the receiver app and starts playback.
Especially:

https://github.com/entertailion/Caster/blob/master/src/com/entertailion/java/caster/Playback.java#L201
https://github.com/entertailion/Caster/blob/master/src/com/entertailion/java/caster/RampClient.java#L128

The guy who wrote Caster and Fling (entertalion) has documented his understanding of the RAMP protocol here:

https://plus.google.com/+LeonNicholls/posts/b3wCmToPehK

and Note that neither Caster or Fling work anymore without a Developer account, and a whitelisted developer appid which you have to put into the app yourself. I guess google changed the method he used to send video to the default app and his method no longer works. So, now you need a custom receiver to make it work...

I'm really interested in getting this functionality working.

According to Google's Receiver Apps page, you only need a developer account whitelisted by Google if you're trying to use a custom receiver app. The default receiver app should allow streaming from anyone: https://developers.google.com/cast/docs/receiver_apps#default

First of all thanks for sharing this. It was helpful in my exercises.
I am trying to using the default app to play some local media file and do randomizations. @altf4 is correct that you don't need a developer account.

Where I am stuck right now is trying to decipher the json format used to post to the default receiver app
I have read the docs and based on https://developers.google.com/cast/docs/reference/messages something like this should work

start_app(host, APP_ID["DEFAULT_MEDIA_RECEIVER"],
        {
        "requestId":"0",
        "type":"LOAD",
        "title":"video",
        "media": {
                    "contentId":"http://myurl/file.mp4",
                    "streamType":"NONE",
                    "contentType": "video/mp4",
                 },
        "currentTime":"0",
        }
        )

When I do the above, I don't get any response and that is not helping.
Is there a way to debug this further ? or is this format better explained somewhere ?

Related to this is https://github.com/vickyg3/UrlPlayer which works fine for me but that requires Chrome and the Chromecast extension.

Thanks

The default media receiver is part of the new API that Google implemented and cannot be started from PyChromecast because it only supports the original API.

[srirajan]

thanks for the feedback. Will see if I can try the new API

[manatlan]

btw, It should be possible ...

try this : https://gist.github.com/TheCrazyT/11263599
it works with me ...

[srirajan]

@manatlan thanks for sharing. That is awesome. I did not have time to hack it but your example works perfectly fine with a local video as well.

[balloob]

I will ask the author if I can clean it up and integrate it into PyChromecast.

[minektur]

Yeah it is what I would have done (instead of the debugger interface) if I
had better debugging/RE skills... If you find yourself short on time, I
could do the integration... lemme know if you want help.

This issue has been resolved. It can be started with
cast.launch_app(pychromecast.APP_MEDIA_RECEIVER)

And can be controller from the MediaController located at cast.media_controller.

Is it possible to use a EXT-X-KEY tag with the default receiver app?
