Chromecast Developper

Hello, I'm looking for a developper who know how to install Chromecast on native mobile app (android and ios) for streaming video. My app is already created and runs. The chromecast is installed on app and it works properly but stops after a few minutes (variables, 2, 6, 31, 15 minutes... after). We conducted several tests in different environments and even all customers using the app have the same problem. We had many feedbacks for this error. And it's not a problem with the Wi-Fi connection between chromecast stick and Wi-Fi router, because i use the Chromecast of Youtube or other apps with Chromecast at my side. And I have no other concern with Chromecast of youtube or with the apps for witch I use Chromecast... So, i do not know where find the error... So, I'm looking for a developer who can just fix it first on Android. As I said previously, Chromecast works well on Android but stops play on tv and returns the video on mobile. So to start, let's first fix the Chromecast stops bugs on android and if it works well, we will make the same config for ios. Sorry but I need a serious developper who has already created Chromecast, who has experience in the field of Chromecast and who can immediately detect errors during tests... Beginners are not accepted for this job... Sorry for that... Another thing... However, to avoid wasting time correcting the old chromecast, I suggest to make a price to create a new chromecast on android and ios ... Propose me two estimates so that I can choose... Thanks
