compression

I'am creating a video from an array of images. The purpose of my work is to create a .mov video with no compression. I have see in developer library that it exist a key "AVVideoCompressionPropertiesKey" but I don't know how to specify no compression with this key. Could you help me please? Here is my sample code : NSDictionary *videoCleanApertureSettings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:320], AVVideoCleanApertureWidthKey, [NSNumber numberWithInt:480], AVVideoCleanApertureHeightKey, [NSNumber numberWithInt:10], AVVideoCleanApertureHorizontalOffsetKey,

My ASP.NET page has following query string parameter: …?IDs=1000000012,1000000021,1000000013,1000000022&... Here IDs parameter will always have numbers separated by something, in this case , . Currently there are 4 numbers but normally they would be in between 3 and 7 . Now, I am looking for method to convert each big number from above into smallest possible value; specifically compressing value of IDs query string parameter. Both, compressing each number algorithm or compressing whole value of IDs query string parameter are welcome. Encode or decode is not an issue; just compressing the value

I've recently been looking into hadoop and HDFS. When you load a file into HDFS, it will normally split the file into 64MB chunks and distribute these chunks around your cluster. Except it can't do this with gzip'd files because a gzip'd file can't be split. I completely understand why this is the case (I don't need anyone explaining why a gzip'd file can't be split up). But why couldn't HDFS take a plain text file as input and split it like normal, then compress each split using gzip separately? When any split is accessed, it's just decompressed on the fly. In my scenario, each split is

I thought this was a simple google search, but apparently I'm wrong on that. I've seen that you should supply: Accept-Encoding: gzip;q=0,deflate;q=0 in the request headers. However, the article that suggested it also noted that proxies routinely ignore that header. Also, when I supplied it to nginx, it still compressed the response message body. http://forgetmenotes.blogspot.ca/2009/05/how-to-disable-gzip-compression-in.html So, how do I tell a web server to disable compression on the response message body? Chawathe Vipul Do you wish encoding to be disabled altogether? Then skip the Accept

I am trying to compress and decompress a Stream using Compression.DeflateStream . Compressing seems to work correctly since the code below compresses my Stream to a 110 bytes long array. However, reading the decompressed Stream results in an empty string. class Program { static void Main(string[] args) { // Compress a random string value string value = Path.GetRandomFileName(); byte[] compressedBytes; using (var writer = new StreamWriter(new MemoryStream())) { writer.Write(value); writer.Flush(); writer.BaseStream.Position = 0; compressedBytes = Compress(writer.BaseStream); } // Decompress

I'm trying to compile the zpipe.c example in my Linux(Ubuntu 8.04) with gcc, but I'm getting some errors, take a look: [ubuntu@eeepc:~/Desktop] gcc zpipe.c /tmp/ccczEQxz.o: In function `def': zpipe.c:(.text+0x65): undefined reference to `deflateInit_' zpipe.c:(.text+0xd3): undefined reference to `deflateEnd' zpipe.c:(.text+0x150): undefined reference to `deflate' zpipe.c:(.text+0x1e8): undefined reference to `deflateEnd' zpipe.c:(.text+0x27b): undefined reference to `deflateEnd' /tmp/ccczEQxz.o: In function `inf': zpipe.c:(.text+0x314): undefined reference to `inflateInit_' zpipe.c:(.text
