These two days I have studied the command for sending streaming media from FFMPEG. Here I will record it for memo.1. udp1.1. send the H.264 bare stream to the multicast address.
Note: The multicast address ranges from 224.0.0.0 to 239.255.255.255.
The following command sends the H.264 raw stream "Chunwan. h264" to the address UDP: // 233.233.233.223: 264

A recent project needs to implement a live streaming media system, so it is a loose on the Internet to see if there are any open source technologies available for use, and a good solution is found, I would like to share with you the following:

Recently, we need to create an RTSP Streaming Media Player. After studying it, we encapsulate an RTSP playing class crtspplayer, and the decoding library uses FFMPEG. Due to the simple requirement and limited time, only the following basic interfaces are available: Play, stop, and pause. The following is a simple RTSP Player Based on the crtspplayer class.
Currently, only videos in h264 format are tested. Videos in other formats are not tested yet. T

One of the most asked questions by opencv users is, "How can I stream videos over the network so I can process it on different computer? "Opencv does not provide such a function
Technical Principles and Playback modes of streaming media
Stream Transmission needs to be cached. Because the Internet implements intermittent asynchronous transmission based on packet transmission, a real-time A/V source or stored A/V file is divided into many packages during transmission, because the network is dynamically changing, the routes selected by each packet may be different, so the delay in arriving at the client may not be the same, or
Recently, I am working on VLC streaming media playback in WPF. Now I can implement VLC local playback in WPF,Streaming playback solves the problem. In the following code, comment out the two pieces of code for streaming media playback. More people care about it ^,For everyone to learn from each other, here I will first write the code and process for VLC local pla
to be less stable, perhaps it is not very familiar with it. Perhaps see everyone is using Nginx HLS, so there is the idea of replacing SRS with Nginx. When setting up the Nginx rtmp service, we refer to the predecessor's nginx build one of the streaming media servers that support HTTP and rtmp protocol, two or three, because it is the first time nginx Add Nginx-rtmp-module module, feel compared with the SRS relative annoying lock, a lot of depende

We know that the hadoop streaming framework uses '/t' as the Separator by default, and takes the part before the first'/t' in each line as the key, and the remaining content as the value, if no '/t' separator exists, the entire line is used as the key.Key/TValueAnd serves as the reduce input. Hadoop provides configuration for you to set separators.-DStream. Map. Output. Field. Separator: Set the delimiter between key and value in map output.-D stream.
program, the file will be automatically deleted. Example: file * fp = tmpfile ();
16. tmpnam (); its prototype is char * tmpnam (char * s); generate a unique file name. In fact, tmpfile () calls this function. parameter S is used to save the obtained file name, returns the pointer. If the pointer fails, null is returned. For example, tmpnam (str1 );
2. Direct I/O File Operations
This is another file operation provided by C. It processes the file by directly saving/retrieving the file, and the

The streaming API reads and writes JSON-content discrete events. Jsonparser reads the data, while the Jsongenerator writes the data. It is the most effective of the three, the lowest cost and the fastest read/write operation. It is similar to the XML Stax parser.
In this article, we'll show you how to read and write JSON data using the Jackson streaming API. Streaming
