% (especially on high bitrates ). cabac (as cavlc) is a lossless method and therefore will never hurt the quality, but will slow down encoding and decoding. Loop/deblocking filter:In contrary to prefiltering (for example via avisynth, done on the input), or postprocessing/filtering (via the decoder, done on the final output ), loopfiltering is applied during the Encoding Process on every single frame, after it got encoded, but before it gets used as reference for the following frames. this helps

AAC English is all called Advanced Audio Coding, Chinese meaning is the advance audio encoding. As compared with the current popular MP3 audio format, with more audio track channel support, higher sampling rate and sampling accuracy, while the compatibility of multiple languages, higher decoding efficiency, has gradually become the successor of the MP3 format bar. In general, AAC can provide better sound quality when comparing MP3 files by a 30% reduction. There are currently three types of AAC

affine transformations (actual particles). Finally, the process of determining which particles are close to the actual particles is done by measure, and the corresponding tracking box for each particle is usually first obtained and then the measure process is performed. Different tracking algorithms also differ in the measure section, for example: IVT (Incremental visual tracking) uses the incremental PCA Online Update template to compare the similarity with each particle tracking box, with the

The structure of code stream in H We first understand the code flow structure, and the reason for this design, understand the code flow structure, the process of encoding and decoding has a specific backing. In fact, the specification is also the first regulation of the code flow structure, and then the structure of the decoder (for the structure of the

Assets and authoring) Game resources are very important for a high-quality game. This doesn't just mean that the game resources should be suitable for game design, and they must be loaded with high quality and fast speed under the hardware limitations of specific platforms. Binary game resources (Binary game assets) A very practical way to ensure that you are always efficient is to bind and load all game resources in binary format. Common resources include images, fonts, sound effects, and 3D s

Composition of live streaming media system Streamingmedia live systems are generally composed of cameras, encoder, image servers, and image display terminals. The camera is responsible for collecting images, the encoder converts and compresses the collected image data, the image server is responsible for storing the image data, and the image display terminal generates images based on the image data.

1. PrefaceGoogle published a paper name in 2017 to teach attention is all you need, proposed a structure based on attention only to deal with sequence model related problems, such as machine translation. Most of the traditional neural machine translation uses RNN or CNN as the basis of Encoder-decoder model, while Google's newest transformer model based on attention has abandoned its inherent stereotypes and has not used any CNN or RNN structure.
