Did not find the reprint function where ... So I can only copy it over. Always want to video audio codec technology to do a simple summary, but suffer from the time is not sufficient, has not been able to complete. Today has a lot of free, and finally can summarize a video and audio technology to start a tutorial, can facilitate more people learn from the zero to learn audio and video technology. It should be noted that this article refers to the vis

Key words:android decode WEBP sample When I knock down the keyboard when there is a deep sense of shame, see the Android 4.0 support WEBP format image, so I am looking for the provision of what kind of api,nnd, obstinately did not find, then hold a try mentality, with bitmapfactory to read, the result is not a problem. Come to a conclusion, as a code farmers, to dare to try to dare to do! WEBP decoding It's no different from your decoding jpg, it's in the drawable or somewhere, and then Bitm

Objective The basic encoding is a standard BASE64 encoding for handling conventional requirements: the output does not add line breaks, and the output is composed of letters plus numbers. Recently made a Web template, which wants to use the Base64 background image. Although the network has a ready-made encoder, but always want to implement one of their own. As many people may not know, the new Base64 class provided by JDK 8 can handle this task very easily: Base64 (Java Platform SE 8). First,

transmission (with Fec\qos function) (6) Artificial packet loss testing function (7) Real-time statistics output line loss packet delay The internal framework of the demo is shown in Figure 7 below: Figure 7 Demo Internal Threading framework Between the video capture scaling thread and the video coding thread, we employ an efficient two-queue mechanism (the queue element is a pointer, access queue without data copy), if the video coding performance is very sufficient, we can also combine the

First of all we need to understand what CODEC means. It is Coder + Decoder = Codec, which is the encoder decoder. That is, the encoder is also the decoder.Website address: http://commons.apache.org/proper/commons-codec/Apache Commons Codec (TM) software provides implementations of common encoders and decoders such as B

This article is translated from TI's Handbook, the Handbook is a study of gpp+dsp development of the Golden Code document, I hope that the introduction of the help, there is an inappropriate understanding of the hope please enlighten.Codec Engine application Developer User ' s Guide.pdf (literature number:sprue67d)"Codec Engine Application Development Manual" http://blog.csdn.net/dyzok88/article/details/42154487Chapter One

After multimedia files are parsed, you need to find the appropriate codec according to mime. 2.3 of the system has two methods: SoftwareCodec and omx node codec. The latter can be optimized with special hardware, the former seems to be relatively standard soft decoding.Below is the codeOmxcodec. cppOmxcodec: createVector FindMatchingCodecs (Mime, createEncoder, matchComponentName, flags, matchingCodecs );I

ProblemA Web page has been obtained in Python:http://blog.csdn.net/hfahe/article/details/5494895The HTML source code, its time UTF-8 encoded.Extract its title section: Title text in: Speech at the Beijing Perl Conference-using Mason to develop high-performance Web sites Then use: Titleuni = Unicode (titlehtml, "Utf-8″"); Or Titleuni = Titlehtml.decode ("Utf-8″"); Decodes it to Unicode, but it makes an error:

I have summarized the commonly used ITU speech codec for your reference: 1. g.711: pulse code modulation (PCM) of voice Frequencies Encoding type: Expanded PCMEncoding rate: 64 Kbps Theoretical latency: the time for processing a sample (1/8000 seconds = 0.125 milliseconds ); Sound Quality: Long Distance quality;Advantages: Low algorithm complexity, low compression ratio (CD sound quality> 400 Kbps), minimum codec
