We are currently integrating the iOS GoCoder SDK in our app and while doing so we saw a bug, that is also available in the GoCoder app:
When you set the camera resolution to 720p or 1080p, the preview has the correct 16:9 aspect ratio and fills the entire screen on an iPhone.
If you change the resolution to 640x360, the preview shrinks to 3:2, even though this is a 16:9 resolution. The streamed video is a valid 16:9 video, so this is problem in the preview only.
Any chance, that this is fixed ?
