The core of audio and video processing lies in understanding the basic process and optimization methods. 1. The basic process includes acquisition, encoding, transmission, decoding and playback, and each link has technical difficulties; 2. Common problems such as audio and video aberration, lag delay, sound noise, blurred picture, etc. can be solved through synchronous adjustment, coding optimization, noise reduction module, parameter adjustment, etc.; 3. It is recommended to use FFmpeg, OpenCV, WebRTC, GStreamer and other tools to achieve functions; 4. In terms of performance management, we should pay attention to hardware acceleration, reasonable setting of resolution frame rates, control concurrency and memory leakage problems. Mastering these key points will help improve development efficiency and user experience.

In predictive analysis, SQL can complete data preparation and feature extraction. The key is to clarify the requirements and use SQL functions reasonably. Specific steps include: 1. Data preparation requires extracting historical data from multiple tables and aggregating and cleaning, such as aggregating sales volume by day and associated promotional information; 2. The feature project can use window functions to calculate time intervals or lag features, such as obtaining the user's recent purchase interval through LAG(); 3. Data segmentation is recommended to divide the training set and test set based on time, such as sorting by date with ROW_NUMBER() and marking the collection type proportionally. These methods can efficiently build the data foundation required for predictive models.

To improve the performance of Java collection framework, we can optimize from the following four points: 1. Choose the appropriate type according to the scenario, such as frequent random access to ArrayList, quick search to HashSet, and concurrentHashMap for concurrent environments; 2. Set capacity and load factors reasonably during initialization to reduce capacity expansion overhead, but avoid memory waste; 3. Use immutable sets (such as List.of()) to improve security and performance, suitable for constant or read-only data; 4. Prevent memory leaks, and use weak references or professional cache libraries to manage long-term survival sets. These details significantly affect program stability and efficiency.

Go language is suitable for network device management due to its concurrency model and high performance. 1. Connecting devices can use third-party libraries such as x/crypto/ssh to achieve SSH connection and execute CLI commands; 2. Bulk management can control the concurrency through goroutine channel to ensure reasonable utilization of resources; 3. Processing manufacturer compatibility can achieve scalability by defining the DeviceHandler interface to customize handlers for different brands of devices.

Common Go image processing libraries include standard library image packages and third-party libraries, such as imaging, bimg, and imagick. 1. The image package is suitable for basic operations; 2. Imaging has a complete function and a simple API, which is suitable for most needs; 3. Bimg is based on libvips, has strong performance, which is suitable for large images or high concurrency; 4. Imagick binds ImageMagick, which is powerful but has heavy dependencies. Quickly implement image scaling and cropping. You can use the imaging library to complete it through a few lines of code in Resize and CropAnchor functions, and support multiple parameter configurations. Adding filters or adjusting tones can be achieved through the color transformation function provided by imagination, such as Graysc

1. Extended plug-ins may frequently read and write disks. It is recommended to uninstall or disable infrequently used plug-ins and pay special attention to ad blocking plug-ins; 2. Cache and temporary file accumulation will cause disk occupancy exceptions. You can clear browsing data or manually delete cached files through settings; 3. Background processes and preload functions may continue to occupy disks, so you need to turn off the "Start Enhancement" function and check the background process; 4. Update problems or bugs may cause exceptions, you can check for update versions, rollback or reset browser settings. In response to the soaring problem of Edge hard drive occupation, checking plug-ins, caches, background functions and updates can be effectively solved.
