Summary of the online G711 codec, it has been to the Andorid system, through the JNI to G711 and PCM, because of the two formats do not have in-depth understanding, so if you want to understand them can Baidu, here is just to achieve such a function.
G711.C contains encoding and decoding methods

Brief introduction
CODEC is actually an acronym for the prefix of the coder and decoder two words. Compressioncodec defines a compression and decompression interface, and the codec we're talking about is a class that implements some of the compressed formats of the Compressioncodec interface, and here's a list of these classes:
Using Compressioncodes to decompress

Learning machine learning problems arise, Baidu has not finished a half-day, but know the reason for the following reasons: Because Python uses ASCII encoding by default, and when Python converts between encodings, the Unicode As an "intermediate code", but Unicode is only 128 that long, so this error is reported here when attempting to convert an ASCII-encoded string to "intermediate encoded" Unicode because it is out of range. Now that you know the reason, it's OK. Not The workaround is

Zxing (pronounced "zebra crossing") is a open-source, multi-format 1d/2d barcode image processing library implemented in Java, with ports to the other languages. We are on using the built-in camera on mobile phones to scan and decode on the barcodes, device without G with a server. However the project can be used to encode and decode barcodes on desktops and servers as.

Come to a conclusion, as a code farmers, to dare to try to dare to do!

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).
