The image is processed in Python using the PIL library, which can be used for some of the most common operations of pictures, such as resizing, formatting, color, rotation, and so on.
First you have to install Python (no introduction here).
After you install Python, it's very easy to install the PIL library, just follow the steps below

1 The concept of the library.
A library is a written, existing, mature, reusable code. In reality, every program relies on a lot of underlying libraries.2 The concept of dynamic library and Static library.

In daily project development, whether it is for business communication between two company projects or to reduce the Compilation Time of the project, sometimes we pack the private content of the project into a static library, or package a small part of the changes in the project into a static

Software development is often a very large project. It takes a lot of brain power. It is often more efficient to use libraries that others have already developed, and the following describes how to develop and use shared library files. Using libraries that others have developed, as if we want to build a car is very difficult, But if all the parts of the car already exist and are available, the work we have to do is assemble, and the assembly process m

The PHP library provides developers with a standard interface that helps developers take advantage of object-oriented programming in PHP. These libraries provide a standard API for specific types of built-in functionality, allowing classes to interact seamlessly with the PHP engine. In ad
. H header files are required for compilation, lib is required for linking, and dll is required for running.
The dependency. lib is not. dll. If DLL is generated, the LIB file is also generated. If you need to complete source code compilation and linking, it is enough to have header files and lib. If dynamic connection is also enabled, dll is enough. In the development and debugging stages, it is best to have both.

The role of the H file is to declare the function interface.

The. h header file is required at compile time, and Lib is required at the time of the link, and the DLL is required at runtime.
Additional dependencies are. Lib is not a. dll, and if a DLL is generated, a Lib file must also be generated. If you want to complete the source code compile and link, there is a header file and Lib is enough. If you also make a dynamically connected program run, there is enough DLL.

Decoding process:
1, read HiSilicon g726 audio data, HiSilicon g726 audio will be more than 4 bytes of HiSilicon header information.
2. Select FFmpeg g726 encoder for decoding. FFmpeg g726 decoder includes: av_codec_id_adpcm_g726, Av_codec_id_adpcm_g726le. Select the av_codec_id_adpcm_g726 decoder type if the HiSilicon g726 stream type is ASF, and select the g726 decoder type if the HiSilicon RFC3551 stream type is Av_codec_id_adpcm_g726le standard.
Instance code:
#define HISI_AUDIO_HERDER_LEN
