Python Caesar Cipher Decoder

假如想象 提交于 2019-11-29 21:15:50
问题 In my lesson I was tasked with creating a Caesar Cipher decoder that takes a string of input and finds the best possible string using a letter frequencies. If not sure how much sense that made but let post the question: Write a program which does the following. First, it should read one line of input, which is the encoded message, and will consist of capital letters and spaces. Your program must try decoding the message with all 26 possible values of the shift S; out of these 26 possible

FFMpeg Android Stagefright SIGSEGV error (h264 decode)

只谈情不闲聊 提交于 2019-11-29 19:57:25
问题 I need to decode h264 file to YUV on Android 2.3+. As I understand I need to communicate with Stagefright, as it`s the only way now, after closing access with OpenMAX IL implementations. I have used FFmpeg 0.10 (and tried 0.9/0.9.1..) for this issue, compiled it with NDK7 (and also tried NDK6b with the same result): ffmpeg version 0.10 Copyright (c) 2000-2012 the FFmpeg developers built on Jan 28 2012 14:42:37 with gcc 4.4.3 configuration: --target-os=linux --cross-prefix=arm-linux

PHP array Encoding and Decoding:Need a function for encoding and decoding string or array with delimiters or array itself

余生颓废 提交于 2019-11-29 18:36:44
I am in a need of function that will encode and decode all the id's of a tree nodes. I function that will check if its a single string or array string or string with delimiters. I am having one plugin for encoding and decoding. here goes my plugin: FIle:encode.class.php <?php /*------------------------- Author: Jonathan Pulice Date: July 26th, 2005 Name: JPEncodeClass v1 Desc: Encoder and decoder using patterns. -------------------------*/ class Protector { var $Pattern = ""; var $PatternFlip = ""; var $ToEncode = ""; var $ToDecode = ""; var $Decoded = ""; var $Encoded = ""; var $Bug = false;

Failed to execute: 0x80070057, when decoding video via ffmpeg with dxva2

时光总嘲笑我的痴心妄想 提交于 2019-11-29 17:52:06
问题 I have successfully implemented a video player using ffmpeg. I am now trying to use hardware decoding but I'm facing a couple issues. I found a post that I followed as a starting point here: https://ffmpeg.org/pipermail/libav-user/2014-August/007323.html I have updated the code that setup the necessary stuff for the decoder. The updated code is available here: https://drive.google.com/file/d/0B5ufHdoDzA4ieVk5UVpxcDNzRHc/view?usp=sharing And this is how I'm using it to initialize the decoder:

How to stop an html TEXTAREA from decoding html entities

你。 提交于 2019-11-29 16:28:09
问题 I have a strange problem: In the database, I have a literal ampersand lt semicolon: <div whenever its printed into a html textarea tag, the source code of the page shows the > as > . How do I stop this decoding? 回答1: In PHP, this can be done using htmlentities(). Example below. <?php $content = "This string contains the TM symbol: ™"; print "<textarea>". htmlentities($content) ."</textarea>"; ?> Without htmlentities(), the textarea would interpret and display the TM symbol (™) instead of "™".

How to write single bits to a file in C

假如想象 提交于 2019-11-29 16:18:41
I am programming an entropy coding algorithm and I want to write single bits like an encoded character to a file. For example I want to write 011 to a file but if you would store it as character it'd take up 3 Bytes instead of 3 Bits. So my final question is: How can I write single bits to a file? Thanks in advance! paxdiablo You can't write individual bits to a file, the resolution is a single byte. If you want to write bits in sequence, you have to batch them up until you have a full byte, then write that. Psuedo-code (though C-like) for that would be along the lines of: currbyte = 0

Parsing XML string using XSLT

最后都变了- 提交于 2019-11-29 15:47:16
I have an XML document that has a TextBlock that contains HTML code. <TextBlock> <h1>This is a header.</h1> <p>This is a paragraph.</p> </TextBlock> In the actual XML, however, it is coded like this: <TextBlock> <h1>This is a header.</h1> <p>This is a paragraph.</p> </TextBlock> So when I use <xsl:value-of select="TextBlock"/> it displays all of the coding on the page. Is there a way using XSLT to convert < to < within the TextBlock element? <xsl:value-of select="TextBlock" disable-output-escaping="yes"/> and the result: <h1>This is a header.</h1> <p>This is a paragraph.</p> Firefox has a

Lua, dealing with non-ascii byte streams, byteorder change

半腔热情 提交于 2019-11-29 10:24:04
问题 Need to encode & decode byte-stream (containing non-ascii characters possibly), from/into uint16, uint32, uint64 (their typical C/C++ meaning), taking care of endianness. What is an efficient & hopefully cross-platform way to do such a thing in Lua ? My target arch is 64-bit x86_64, but would like to keep it portable (if it doesn't cost me on performance front). e.g. decode (say currently in a Lua string) -- 0x00, 0x1d, 0xff, 0x23, 0x44, 0x32 (little endian) as - uint16: (0x1d00) = 7424
