only contains one type of pixels, that is, a single 8x8 brightness (y) pixel block, or a single 8x8 red (CR) pixel block, or a single 8x8 blue (CB) pixelBlock. It is the smallest unit that provides the DCT coefficient, that is, its function is to transmit the DC component coefficient and the AC Component Coefficient. If you want to perform DCT on the macro block, you must first divide the macro block into

5. MPEG audio tags MPEG audio tags can be divided into two types: ID3v1, which has a file tail and a length of 128 bytes, and ID3v2, which is an extension of ID3v1 and has a file header with an indefinite length. 1. ID3v1 The ID3v1 label is used to describe the MPEG audio file. Including artist, title, album, publishing age, and genre. In addition, there is addit

Guo Bin, Professor of the Department of television engineering, Beijing Broadcasting Institute 2) Two-Dimensional DCT MPEG adopts the discrete cosine transform (DCT-discrete cosine) proposed by Ahmed N. et al. in 1974.Transform compression algorithm to reduce the space redundancy of video signals (spatial)Redundancy ). Because static images and prediction error signals have very high spatial redundancy, the

1. Add video path to component This.axWMPlayer.URL = System.Environment.CurrentDirectory + "//avseq01." DAT "; 2, the Playstatechange event to add the following codeif (axwmplayer.playstate = = WMPLib.WMPPlayState.wmppsStopped){AxWMPlayer.Ctlcontrols.play ();} or set as follows: AxWMPlayer.settings.setMode ("Loop", true); 3, the media file spread full component

In the previous article, the local playback process of mediaplayer (1) describes the setdatasource process of mediaplayer. This article describes the prepare process of mediaplayer. The process before prepare goes to awesomeplayer, which is basically the same as that of setdatasource. Here, it is omitted directly. The following will start with awesomeplayer. status_t AwesomePlayer::prepare() { ATRACE_CALL(); Mutex::Autolock autoLock(mLock);
