[StaehliJ]

According to the official Exoplayer documentation about Network stacks, OkHttp may improve network performance especially with the usage of CDN's.

Most of the SRG contents are stored on a Akamai CDN, maybe using OkHttp extension may improve the performances.

• Use OkHttpDataSource inside the demo
• Handle Token protected content
• How to measure performance gain?
• Use CronetDataSource inside the demo too

Cronet on paper should improve response time when loading media from url.
Bottle neck is when using urn that passe by retrofit and OkHttp, we can improve this further by using Cronet with Retrofit with some limitiations and/or using Ktor with a CronetClient.
