    Multiple Resolution Support in NDIHX Broadcaster in iOS

    Hi,

    I'm running NDIHX Broadcaster on an iPhone SE (gen. 1), iOS version 14.0.1, talking via 5GHz WiFi to a Mac Mini (2012) 2.3Ghz Quad i7, OSX 10.15.7 running OBS Studio (26.0.2, 64 bit).

    All works great! However, in NDIHX Broadcaster, I can only toggle between three camera resolutions (low, medium and high: corresponding to 640x480, 1920x1080, and 3840x2160 pixels) although the iPhone camera supports eight. Not all eight would be that useful (to me, at least), but 1280x720 is missing, and that definitely would be! Could you change the 3-stop toggle to a 4-stop toggle, and slot in 1280x768 somehow?

    I tried using NDIHX Capture along with a full-screen camera app (https://apps.apple.com/sn/app/full-s...a/id1504011874) as an alternative means of bridging the gap between 640x480 and 1920x1080 (hoping to use 1136x640 - i.e. the native SE screen resolution), but got defeated by this as well! Basically, when the phone is on its side to operated in landscape mode, NDIHX Capture gets upset and switches from 640x 1136 to 640x362 output, rather than to 1136x640! Admittedly, I think this is specifically a problem with this app & NDIHX Capture (NDIHX Camera is fine with other apps in landscape mode, but they don't give me the 'clean' camera functionality that I need). On balance, rather than chasing my tail on this problem, I'd rather have the solution in NDI Broadcaster. Seems to me others would appreciate as well - 720p is ideal for some applications.

    I'm sorry, I'm probably just a tiny bit confused: "NDIHX Broadcaster"? Are you referring to the NDI HX Camera app for iOS, or something different?

    Whoops! I mean "NDIHX Camera". I've got "Broadcaster" on the brain cos I've been playing with a Larix RTMP/RTSP/SRT client recently, and they call their iOS camera app "Broadcaster." Sorry!

    I re-typed my post with the bugs fixed (hopefully)! I don't think I have the means to edit it, but if you do, this is how it should have read: -
