🐛 Memory Leak on camera.takePhoto after 6 six shots.

[mdottavi]

What's happening?

I integrated latest RNVC 4.0.3 in my project.

After taking 6 photos correctly (I checked files are saved in cache folder of the device)
the takePhoto method get systematically stuck at the seventh execution (await props.camera.current.takePhoto does never end).

If I switch to another View and get back to the Camera View it resets and I can still get 6 goot photos before stucking again.

I tried to give some time from one shot and another but it does not change the issue. Fully reproducable Code is provided.

Devices: Motorola G84 5G

The error from LogCat at seventh shot is:
ImageReader-4080x3072f22m9-8855-21 waitForFreeSlotThenRelock TIMED_OUT dequeuedCount=0, acquiredCount=3, mMaxAcquiredBufferCount=9, mMaxDequeuedBufferCount=8
ImageReader-4080x3072f22m9-8855-21 dequeueBuffer: No free buffer is found!
getBufferLockedCommon: Stream 3: Can't dequeue next output buffer: Connection timed out (-110)

From the traces it look some buffer is not flushed after image acquisition.
Do I need to flush/empty some data ?

Can you reproduce this issue in the VisionCamera Example app?

I didn't try (⚠️ your issue might get ignored & closed if you don't try this)

Additional information

• I am using Expo
• I have enabled Frame Processors (react-native-worklets-core)
• I have read the Troubleshooting Guide

Motorola G84 5G (Android 14)
Same thing happens (6 photos good) seventh stucks also on Android OnePlus Nord 3 (Android 14)

The issue does not show up in the CameraExample as it is....
BUT just removing the
format={format}
parameter passed to the Camera Component it happens exactly the same.

hm interesting.
