I have a screen attached to a Chromecast v2.
I have a Raspberry Pi 2, with Emby server with DLNA support.
From my iPad, with the Emby official application, I can stream all my movies.
But, for each video, there is transcoding, my CPU is > 99% even for videos that don't require transcoding because the Chromecast v2 support it.
If I use a simple iPad application to play a DLNA video to my Chromecast (without any transcoding), I can play the same video with less than 5% of CPU usage.
So, I suppose this could be fixed if I create a ChromeCast profile to skip some supported audio/video codecs, to be in direct play, but it's really complicated for me to do this because there is a lot of informations to known, and my knowledges are too limited to fill this correctly.
I would like to known if someone have already created this DLNA profile and could share it please?
