decoding

I have a string of Hex values... String hexString = "8A65"; I need to convert this string into their Unicode equivalents. The tricky part is that I need to support different code pages and some code pages have '8A65' = one character whereas other code pages would convert it into two characters. I have no prior knowledge of which code page I will be using until I need to perform the conversion. I've tried all sorts of stuff such as byte[] original = Encoding.Unicode.GetBytes(hexString); byte[] conv= Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(932), orig); char[] chars = Encoding

I'm currently experiencing artifacts when decoding video using ffmpegs api. On what I would assume to be intermediate frames, artifacts build slowly only from active movement in the frame. These artifacts build for 50-100 frames until I assume a keyframe resets them. Frames are then decoded correctly and the artifacts proceed to build again. One thing that is bothering me is I have a few video samples that are 30fps(h264) that work correctly, but all of my 60fps videos(h264) experience the problem. I don't currently have enough reputation to post an image, so hopefully this link will work.

I cant find how to decode string encoded in sha1. I'm suprised that i can't find simple function in python docs or google doing sha1 decoding. I give up. I need help.. SHA1 is a hashing algorithm. Hashing is one-way, which means that you can't recover the input from the output for any non-trivial hash function. A simple example of a one-way hash function would be adding together all the digits of a number. 1234 would hash to 1 + 2 + 3 + 4 = 10 , but so would 4321 , 1900 , 5050 , and many other numbers. Given just the hash value of 10 , you can't tell whether the input was 1234 or 5050 because

I'm using serialization and deserialization in C# for my Project (which is a Class). They are serialized and saved to an XML file. When loading the Project, all goes well. Now I'm trying to encode the serialized Project to Base64 and then save the file, which goes well too. The first line of the file (before encoded!) looks like this: <?xml version="1.0" encoding="utf-8"?> <Project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> When I decode the file, there's a ? added in front of the line: ?<?xml version="1.0" encoding="utf-8"?> <Project

I'm working with mails, and names and subjects sometimes come q-encoded, like this: =?UTF-8?Q?J=2E_Pablo_Fern=C3=A1ndez?= Is there a way to decode them in Ruby? It seems TMail should take care of it, but it's not doing it. ankimal I use this to parse email subjects: You could try the following: str = "=?UTF-8?Q?J=2E_Pablo_Fern=C3=A1ndez?=" if m = /=\?([A-Za-z0-9\-]+)\?(B|Q)\?([!->@-~]+)\?=/i.match(str) case m[2] when "B" # Base64 encoded decoded = Base64.decode64(m[3]) when "Q" # Q encoded decoded = m[3].unpack("M").first.gsub('_',' ') else p "Could not find keyword!!!" end Iconv.conv('utf-8'
