Client: Option to change the image/video transition default settings. For example, upon loading an image/video, transition is set to PUSH - 30 frames - EaseInQuad - LEFT - Seek 0 - Loop = true, etc.
Or Better yet, have the option to assign separate default transitions for images and video.
I dont know if this is a good idea or if its even do-able, take in webRTC-stream in client like the tool āDecklink inputā. No idea how it could be practically organized.
Another: possible that in the client define out-transition. If your using Caspar for screenproductions it would be usefull to have better ways to take out layers than transparent PNG:s especially for videos, images and Decklink inputs
Only way to take in WebRTC would be with a HTML template. That also means you donāt have embedded sound (until CEF audio works within Caspar). Other option would be to find software that could translate webrtc to another protocol.
Regarding transparency - you can use any image or video as the key layer for another layer with MIXER.
as a wishlist feature, we could have a native webrtc producer!
Regarding tranparency i use the transparent PNG as the following example:

My most important wish (not for me but for every new user) INtergrated the Frontend GUI to Server release.
I would prefer a web interface as a frontend, which would comply with running the server headless.
I understand that if your running the Server through the frontend you miss out on some nice features like multiply configurations, So I like how it works in 2.0.7 where you can start frontend if you want or just the console if you prefer that. A webinterface would be perfect but still you cant(I think) get a channelgrid or diagnoce window though a webinterface. I have for problems installed TightVNC on my servers which means I can run them headless if I want to.
The frontend supporting multiple config files could be something to add to the wishlist if you want that.
There is a issue on github to replace the diag window with an external tool anyway https://github.com/CasparCG/server/issues/899, which would play well with a webinterface frontend.
+1 for rendering to file. This would be a huge feature for us, it is available in other renderers such as Viz RT

Magewell video card support would be great. Iām not a fan of Black Magic Decklink.
we talked to them for a bit at IBC, but they donāt have an output card yet. thatās in the works though, and if itās any goodā¦ who knows.
Interesting to know thanks, Iāll watch this space!
I just saw an interesting product featuring Magewell cards, Iād be great to be able to use it with Caspar but I guess the integration of this cards is not in great demand around hereā¦
Expose Channel/Layer as HTML video/audio input
I like the idea of having a live camera feed inside a html template, like a classic webcam for browser, and could be nice to have a channel/layer as input, rather than a direct decklink. Maybe also available for more than one template (ex. preview). Could be interesting even for AR in conjunction with threejs.

Having a server running on a Mac arm, either under linux or natively, with gpu support. Well, because mac usually have a lot of thunderbolt ports and are well build and powerful computers.
Hide media(folders) from media-scanner, like:
user_avatars_hidden/user12312.png
or
user12312_hidden.png
This way when working with large media sets, they donāt mess up the media lists.
Also a AMCP command like:
/tls/foldername
Only returns media from that media subfolder.
