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,

Unicodedecodeerror occurs while running the Scrapy crawlerPaste the wrongThe reason is related to the registry, which may be related to the GBK format of some native software to the registry, resulting in Python's inability to install third-party libraries.Workaround: Open the mimetypes.py file under C:\Python27\Lib and find about 256 lines (you can use the notepad++ search function)' default_encoding = sys.getdefaultencoding () '.Before this code, add the words'gbk': reload (SYS) sys.

The project uses video codec, which has been around for the last half a month. To be honest, it has taken a lot of detours and wasted a lot of time. Record your final results here, hoping to help others.

PDU codec details Brief Introduction SMS is a specification developed by ETSI (GSM 03.40 and GSM 03.38 ). It can send up to 160 characters, when using 7-bits encoding. 8-bit encoding (up to 140 characters) is usually not displayed directly through the mobile phone; it is usually used as a data message, such as pictures and ringtones in smart messaging) and ota wap settings. 16-bit information (up to 70 characters) is used to display Unicode (ucs2) tex

It is a kind of encoding with the highest quality requirement. It is a non-linear system. Therefore, it tries its best to use the jitter algorithm during the Encoding Process (you can also set it to not shake) to simulate the effect of the true color. This algorithm is alm
