1. Download NDK r6 and FFmpeg 0.8.1
Android NDK r6
FFmpeg 0.8.1
2. Extract
Extract the android-ndk-r6-linux-x86.tar.bz2 to the/home/pekall/opt directory and add the ndk path to the path environment variable
Decompress the ffmpeg-0.8.1.tar.gz to the/home/pekall/Projects_private/FFmpegPlayer/lib directory
Rename the directory/home/pekall/Projects_private/FFmpegPlay
1) The Chinese characters received by query_string_decoded in R6 are garbled characters, rather than the Chinese characters decoded under R5.It became a mess.
Code
I wonder if it's a R6 bug? Fortunately, the @ urldecode formula is added to R6. The solution to query_stringdecoded is as follows: 1) Use QUERY_STRING to receive parameters. Chinese characters are
With the support for native activities In r5, the attention to ndk is tight, so I hope to have more support for c and c ++. The following is the description of r6 in changes.html.
Android-ndk-r6
Important changes:-Official support for the x86 ABI.This release of the Android NDK now provides support for the 'x86 'ABI.This allows you to generate machine code that runs on future x86-basedAndroid devices.

The purpose of this article is not to completely port Python 3.2 to Android, but to compile a link library that can be used in your own program.
After porting boost 1.47, the next target is Python 3.2. Currently, Python only has 2.6.2 unofficially ported to Android (see p4a), and they are delayed in Porting 3.xbecause they think 3. X is useless -_-. It seems that this task can only be done by yourself. The difficulty of Python 3.x is co

51 single-chip microcomputer assembly delay program algorithm detailed
In this paper, 12MHZ crystal oscillator is used as an example to explain in detail the precise algorithm of assembler delay in MCS-51 MCU.
instruction cycle, machine cycle, and clock cycle
Instruction Cycle: The time required for the CPU to execute an instruction is called the instruction cycle, which is based on the machine cycle, with different instructions and different machine cycles required.

involves processing a lot of related environment variables, only the framework of Assembly implementation is listed here (Standard 51 assembly, dual dptr) as follows:Dptr and dptr1 both point to the beginning of the text message. R1 stores the outer loop variable. The inner loop variable is R2 and the initial value is 1. R3 stores the total length of characters to be converted, and configured.
In fact, each inner loop is processed in two bytes. Here, the two bytes are called the first byte and
