[Bug]: Poor video quality on iOS

[jbuhler-c4]

Context

I use this project in custom, native apps running on both iOS and Android. We use FreeSwitch.

General information

• Device: i* - Not limited to a specific device
• OS: iOS
• Version of the SDK: 5.1.24

Expected behaviour

When calling an intercom endpoint, the video on iOS has low quality when compared to an Android device. The negotiated codec is H264 at a bitrate of 90,000 on both iOS and Android. I suspect that this is a scaling issue since the codecs and bitrates are identical between the platforms.

We previously logged this bug at https://bugs.linphone.org/ (#0009059) and it was suggested that we try updating to liblinphone 4.5. We've done that, and a few versions since, but haven't seen any improvments in the video quality for iOS when compared to Android.

To Reproduce

It happens with every call we make.
