DJI SDK 5.13 - Mini 4 Pro – Unexpected values from CameraKey.KeyVideoResolutionFrameRate

[mitchrsm]

I'm using the CameraKey.KeyVideoResolutionFrameRate key to retrieve the supported video resolutions and frame rates on the DJI Mini 4 Pro.
The call returns successfully, but the data seems incorrect or incomplete:
[
{"resolution":22,"frameRate":1},
{"resolution":16,"frameRate":1},
{"resolution":10,"frameRate":1},
{"resolution":4,"frameRate":1},
{"resolution":22,"frameRate":2},
{"resolution":16,"frameRate":2},
{"resolution":10,"frameRate":2},
{"resolution":4,"frameRate":2},
{"resolution":10,"frameRate":4},
{"resolution":4,"frameRate":4},
{"resolution":10,"frameRate":5},
{"resolution":4,"frameRate":5}
]

Mapping these enum values, it corresponds to something like:
Resolution | Frame Rate (fps)
4096x2160 | 24, 25
3840x2160 | 24, 25
1920x1080 | 24, 25, 48, 50
1280x720 | 24, 25, 48, 50

This does not reflect the full list of supported combinations available on the Mini 4 Pro, which should include options like:

4K @ 60fps
1080p @ 60fps
And more

I get the same result both programmatically (via SDK) and using the official SDK Sample App (see screenshot below for confirmation).
Is this a bug or I'm doing something wrong ?

Dear Developer,
Hello and thank you for reaching out to DJI Innovations.

I'm sorry I can't see the picture you provided. It seems to be truncated.
You can obtain the range of video resolutions and frame rates supported by the camera lens through KeyVideoResolutionFrameRateRange.

KeyVideoResolutionFrameRateRange：https://developer.dji.com/api-reference-v5/android-api/Components/IKeyManager/Key_Camera_CameraKey.html?search=keyvideoresolutionframeraterange&i=0&#key_camera_videoresolutionframeraterange_inline

We appreciate your email and wish you a wonderful day!

Dear Yigui Liu,

Thank you very much for your reply.

Yes, I'm already using the KeyCameraVideoResolutionFrameRateRange key as suggested. However, as mentioned in my previous message, the values it returns do not seem to be accurate or complete.

Here is the array of results I'm getting:
[
{"resolution":22,"frameRate":1},
{"resolution":16,"frameRate":1},
{"resolution":10,"frameRate":1},
{"resolution":4,"frameRate":1},
{"resolution":22,"frameRate":2},
{"resolution":16,"frameRate":2},
{"resolution":10,"frameRate":2},
{"resolution":4,"frameRate":2},
{"resolution":10,"frameRate":4},
{"resolution":4,"frameRate":4},
{"resolution":10,"frameRate":5},
{"resolution":4,"frameRate":5}
]
Some expected combinations are missing, and a few listed combinations seem unsupported by the camera. For instance, resolution "22" corresponds to "4096x2160", which is not supported on the Mini 4 Pro as far as I know.

I'm attaching the screenshot again, hoping it comes through properly this time.

Thank you again for your support and have a great day!

Dear Developer,

Regarding the inaccurate acquisition of the camera lens video resolution and frame rate range by using KeyCameraVideoResolutionFrameRateRange on the Mini 4 Pro model, the MSDK R&D team has also confirmed that this is a bug, which is expected to be fixed in the MSDK v5.15.0 version.
