15 | Representatives of streaming computing: Storm, Flink, Spark Streaming
The big data technology introduced earlier mainly processes and calculates large-scale data on storage media. This type of calculation is also called big data batch computing. As the name implies, the data is calculated in batches, such as one day’s access logs, all order data in history, etc. These data are usually stored on the […]
Java 8 Stream: Mastering the Essence of Streaming Programming Title
Foreword This article is from a blogger I like. Mainly used for learning and recording purposes. If you have any questions, please message me privately. Thanks! Master Stream flow Two weeks ago, a reader strongly requested me to write an article about Java Stream. I said that there are already many articles on the market. […]
windows ffmpeg + nginx + videojs implements rtmp push and pull streaming and hls push and pull live streaming
The previous blog has written about using ffmpeg + nginx to build an RTMP push and pull live broadcast environment under Windows. It can be played through PC client software such as ffplay and vlc. However, due to browser playback reasons, the RTMP stream passes through the browser. Playback must use the flash plug-in. The […]
Exception handling of StreamingResponseBody
Recently I have been working on the export function of Excel files with large amounts of data. Utilize database cursor query and POI’s sxssf technology to achieve smooth conversion of database data into streams and return to the front end. The front end saves the stream bit by bit into the memory through fetch, and […]

A multi-threaded approach to faster OpenCV video streaming in Python
Overview In this article, we will see two Python code examples without multithreading for reading video frames from a camera. We’ll see the difference in FPS obtained with/without multithreading. What is multithreading? A thread is an execution unit in a process. Multithreading refers to the concurrent execution of multiple threads by quickly switching control of […]
