Video Feed Freezes During Recording in 4K/30 or 4K/25 (DJI Mini 3)

[mitchrsm]

Hi, I encountered an issue using the DJI SDK sample code and the Mini 3.

When the camera is set to record in 4K/30 or 4K/25, as soon as I press the record button, the video feed completely freezes. Once I stop the video recording, the video feed resumes.

This issue does NOT occur in:
4K/24
Other resolutions and frame rates such as 2.7K/30.

Devices Tested:
Galaxy S21 Ultra (Android 14)
Galaxy A33 5G (Android 14)
Both devices exhibit the same behavior.

Steps to Reproduce:
Use the DJI SDK sample code.
Set the camera resolution to 4K/30 or 4K/25.
Press the record button.
Observe that the video feed freezes immediately.
Stop the recording and observe that the video feed resumes.

Expected Behavior:
The video feed should remain smooth and uninterrupted during recording in all supported resolutions and frame rates.

Additional Notes:
The issue is specific to the Mini 3, as testing the Mini 3 Pro under identical conditions does not result in the problem.
Firmware and SDK are updated to the latest versions.

Hi,

I have uploaded a video demonstrating the issue to the provided link.

I am using v5.11 of the DJI SDK.
I reproduced the issue by downloading the latest demo app from the SDK, setting the AppID and DJI KEY, and running it.

As shown in the video:

The camera is set to 4K/30, and the video feed freezes as soon as I start recording (the same issue occurs in 4K/25).
If I switch the resolution to 4K/24, the issue does not occur.
In the video, I used the DJI FLY app to change the camera resolution because I couldn't find a way to do it directly within the sample app.

Additionally, in the app I am developing, I am using the same FPV widget from the sample app, and the issue persists there as well.

Let me know if you need more details or additional tests.

Best regards,
Michele
