I'm working with Android Camera2 API and get this after getting a set of photos from camera on my smartphone with Android version 6. h. Images are captured at sensor rate and are sent to preview and to the circular buffer pool (either as raw Bayer or as processed/semi-processed YUV). The only solutions I have now is to read the buffer at 30fps so it will clean the buffer quickly and there's no more serious The camera framework also supports HIDL camera HALs, however camera features added in Android 13 or higher are available only through the AIDL camera HAL interfaces. With this mode, CameraX keeps dropping incoming frames until the current frame is closed. Clear video frame from surfaceview on video complete.
