Play Video From Memory Stream?
May 5, 2010I have an application that sends Bytes of data through UDP, these bytes are read from an AVI file when the client receives the bytes it builds the AVI file on another computer perfectly but I want to be able to use the received bytes to play the video from the stream. Does anyone know how I can play the video from a stream? I tried using DirectShow but I don't know how to use a stream as video let alone having AVI files play with DirectShow.
My main goal is to have the application slowly "buffer" the movie for the client as they watch.

May 25, 2012in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing

View 12 RepliesC# - .Net - How To Prepend A Stream
Nov 21, 2011I'm loading blobs out of a database as a byte array and I put them in a memory stream so that I can load them into an xmldocument for parsing.However there are blobs that have multiple root nodes, this causes the parser to blow up.My solution is to just make a new root node that encompasses the whole blob. I can add onto the end just fine with a streamwriter however I can't figure out how to add onto the beginning.How can I prepend to a stream?
Update:I was having too much trouble getting this to work. The "XML" I was extracting was not proper XML and I kept on having to add more and more regexes to remove bad XML before the XmlDocument Load. I ended up using the HtmlAgilityPack to parse out my valid sections of XML and I put those inside their own xml documents.
C# - Get The Bytes From A Stream?
Jun 4, 2012I'm writing a VB.net application (but you can answer in C# if you want, no problem) that uses a 3rd party .NET library. In particular, one method in this library takes an IO.Stream as input (among other things) and writes the results of its processing to said stream. My problem is that the method CLOSES the stream after writing to it, so I can't read back the data that it wrote in it!To be more specific: it works, of course, if the stream is a FIeStream , since it writes the data on disk, but what if I want to read the data directly to memory? I tried using a MemoryStream, but as I said, when the method returns the stream is already closed, and I can't read back anything from it.

.net - Load An Unmanaged DLL From A Stream?
May 18, 2012I have an application written in .NET 4.0 that needs to load in memory a native DLL (written C). At the moment I am using a P/Invoke call to LoadLibrary passing the path where the DLL is located. This works, but due to the fact that this DLL comes from a DB, I would like to know if it is possible loading it through a stream, avoiding then the necessity to store the DLL somewhere in the filesystem.
View 2 Replies.net - Overlaying Images From Stream
Dec 27, 2009I'd like to overlay a number of images (PNG, same size for all, with transparency). So far, my code is as follows.

Now, I would like to overlay one more image, but this is based on a user's input from a textbox. So, to get that image, we need to take the user's input, and get the respective resource file. I do it as follows:

The overlay works correctly. So question is: Why is the overlay not working from the stream? Edit: It turns out that the overlay does actually work, but seems to overlay an enlarged image rather than the true size. Would there be any reason for this?
.net - Stream Connection Using Httpwebrequest?
Apr 3, 2012I have created a httpwebrequest connection to a streaming API after trying a tTCPClient which just never ended up working. My concern is whether my code is correct and that I am actually reading in new data and that the connection is maintained. Initially I had been reading into a buffer and just loaded everything into a file after max size, but figured it would be simpler to read a line, since each entry was being sent delimited by line feeds.
rStream = webrequest.GetResponse().GetResponseStream
rStream = New GZipStream(rStream, CompressionMode.Decompress)
If rStream.CanRead then

It looks like I am continuously reading and not sure if I am reading redundant data here. Also another question is that if I were to use a thread to appendToFile, would that maintain the connection to the stream?

Compressing A Stream Rather Than A File?
Apr 3, 2010I've downloaded ZLIB.NET from here and the example VB.NET code they provide works fine. It's very short so I'll paste it here for reference:
vb
Public Shared Sub CopyStream(ByRef input As System.IO.Stream, ByRef output As System.IO.Stream)
Dim num1 As Integer
[Code]...
Note that the CopyStream() subroutine is identical. The problem is that although decompressing seems to work fine, compressing does not. If I take a byte stream, compress it and then decompress it using the above code, I get a truncated version of the original stream (as an example, a 360485 byte stream becomes 311518 bytes). The resulting bytes match the original stream up until the point where it's cut off.
The only information I can find about streams being truncated is due to missing stream.Flush() commands but the output stream is flushed in the CopyStream() subroutine.
