Video Encoding: the so-called video encoding method refers to converting a video format file into another video format file through a specific compression technology.Currently, the most important encoding and decoding standards for video stream transmission are ITU's H.261 and H.263,M-JPEG of the moving static image expert group and the mpeg series standard of the International Standardization Organization Motion Image Expert Group,In addition, real-n

This article briefly introducesVideo Transcoding TechnologyOfDefinition, classification and implementation methods, focusing on how to use transcoding Technology in video engineering, including the use of transcoding technology and its advantages. This article analyzes how to use the transcoding Technology in stream mode and file mode. ConnectThe flexibility and versatility of the transcoding system are discussed by analyzing the two engineering instances of remote transmission of video data and

in the DVD is VOB format, but due to different standards, there will be other formats. The simple way to do this is to have each folder open, and the file is very large (usually more than dozens of MB) is the real video. After you find the video, copy and paste it to the hard drive. DVD has more than one video file, usually a large scene of a video file; Step three: Convert the video file into another format, and then edit it. Video conversion, cutting, interception and merging Many video fo

Design and Implementation of an Embedded Network Camera Based on AT91RM9200: 14:32:54 Source: Micro-Computer Information Author: Zhao yinwei Xie Shengli 1. IntroductionWithWith the rapid development of communication and network technologies, network-based remote real-time monitoring of important places has attracted the attention of people. In this context, network cameras have become the focus of attention. The Network Camera must be of high definitionDegrees of real-time video information is t

Quarter Pel = quarter pixel = 1/4 pixel = qpel:During Mpeg Compression, p-frame compresses the image based on the previous image, and B-frame compresses the Image Based on the front or back.At this time, we only need to record the differences between the reference image, that is, the error of prediction, and the moving direction of the object (Motion Vector mV ),You do not need to re-compress the entire image, so you can save a lot of bits to achieve

I. Audio compression encoding standard. 1. mpeg1 Standard Mpeg1 audio compression algorithm features: 1) the input signal of the encoder is a linear PCM signal. The sampling frequency is 32 kHz, 44.1khz or 48 kHz, and the output bit rate is 32-384kbit/s. 2) the compressed bit stream supports both single and dual channels. 3) The mpeg1 audio compression standard provides three independent compression layers: Layer 1 (layer1), Layer 2 (Layer2), and Layer 3 (layer3) 4) MP3 is a MPEG1-Layer3 standar

MPEG-1: Is the first video and audio lossy compression standard developed by the MPEG organization. The video compression algorithm was defined in 1990. At the end of 1992, MPEG-1 was formally approved as an international standard. MPEG-1 is a video and audio compression format that is customized for CD-ROM media. A 70

　　MPEG Format: Its English is all called Moving Picture Expert Group, that is, the motion image expert groups format, the home often see VCD, SVCD, DVD is this format. MPEG file format is the international standard of motion image compression algorithm, it uses the lossy compression method to reduce the redundant information in the motion image, and it is more clear that the

If you like watching movies, you must be familiar with the 1080 p, AAC, and x264 terms. So what information does they contain? Let's take a look at "depth. Let's talk about 360 P, 480 P, 720 p, and 1080 p. When I see this, the otaku in front of the screen will say, I only know 3 P, there are 1080 p? Actually, here P indicates a progressive scan. 720 p means a 720-line scan, and 1080 p means a 1080-line scan. The larger the number, the higher the resolution. You can see the data in the next grou

The appearance of digital camera and digital camera makes the connection and transmission of camera, camera and computer more convenient. The 4 "I" (iphoto/imovie/idvd/itunes) of Mac OS X 10.2 Systems showcases the concept of digital video and digital Life for beginners and home users. Where iphoto is a digital photo management editing software, imovie is a video movie editing software, iDVD is a DVD burnin

Statement 1: Although Isma and MPEG-2 ts over IP can be used for IPTV stream transmission, but due to the Mechanism and the original intention of different standards, there are some differences in IPTV service support, the specific analysis is as follows: 1. Support for business functions Isma currently supports MPEG-4 and H.264 and does not support other encoding standards. As video and audio streams are t

compression and visual compression. Below is a main flow chart of the encoder: Figure 3 Figure 4 Figure 3 and figure 4 are two flows. Figure 3 is intra-frame encoding, and figure 4 is inter-frame encoding. The main difference shown in the figure is that the first step is different, in fact, these two flows are also combined. We generally say that I and P frames adopt both intra-frame encoding and inter-frame encoding. Encoder Selection The principles and basic procedures of the encoder have be

1. Premiere5.5 Premiere5.5 is the most popular video editing software, it supports MPEG4, we can use it to edit MPEG4 file, just like the normal video of editing. In addition, if you want to generate MPEG4 after the video project is edited, you can select File/export/movie and the Export Movie dialog box appears, as shown in Figure 1 Figure 1 Exporting the Movie file dialog box Click the Settings button, eject the Export Movie settings panel, select video settings in the first Drop-dow

Ultra Video Joiner The Ultra Video Joiner is a tool to help you connect or merge Avi/divx,mpeg i/ii,vob,dat,wmv,asf videos into a large variety of video files in various formats. You can add an unlimited number of video files to the list and easily rearrange their order when needed, and then merge the video files into a large avi/divx,mpeg i/ii,wmv/asf format video file. This procedure does not require any

One, to solve the problem that QuickTime recording screen can not bring sound:Use the QuickTime screen under MacSoundflower->audio Setup->soundflower (2ch), the right mouse button, in the pop-up menu, "Use this device for sound input" and "Use this device for sound output" are dimmed.At this point we can no longer hear the sound of the Mac, but can record a recording screen with a sound through QuickTime.You need to set it up before the QuickTime recording screen:After recording, in order to hea

, it is quite far from the high-definition digital TV.High Definition Digital TV (HDTV) is the future development direction. By now, all analog TVs have been eliminated, and TV Station shooting, recording, and editing devices have also been replaced, what people will see on TV screens will be high-definition TV pictures and more functions. HDTV will bring TV into a new era.Someone asked if the current digital set-top box receives a high-definition digital TV signal? No. After a digital set-top b

In MPEG-II standards, in order to combine one or more audio, video, or other basic data streams into one or more data streams for storage and transfer, it must be re-packaged and encoded. In the code stream, it also needs to insert various time tags, system control and other information, and finally sent to the channel encoding and modulation. In this way, two types of data streams, TS and PS, can be formed, which are suitable for different applicatio

MKV is the most common of these three files. Matroska's biggest feature is the ability to accommodate a variety of different types of video coding, audio coding and subtitle streaming, and it can accommodate very high density RealMedia and QuickTime files, and organize their audio and video to achieve a better

BecauseEarlier WEB servers on the Internet were primarily UNIX-based, so the files in AU format are also commonly used in today's InternetSound file format.
