Hello, I am using VC++ 6.0. How to record internet stream(video) in C++/COM? Are there any libraries/API for this task? internet stream can be in any format, or if still insisted, in .flv format. Any tutorial links or tips are welcome as well. So far I tried to establish a connection to a server using CMySession(derived from CInternetSession). But I am stuck here, how to detect a stream(from the server), and then write that stream into a file.

How about DirectShow[^]?

DirectShow can be used for recording streams coming from an input device (say webcam, camcorder, dvds etc) but I am not sure if it works for recording internet media stream. I didn't find any articles/samples/tutorials on this topic.

As far as i know, it depends only on what you put in the graph. You can render streams from an URL, and to record it you can e.g. replace the renderer filter with a compressor and disk-writer filter. I see no reason why that wouldn't work.

Ok, if it works, what are the necessary components for the task? (I am new to COM and directshow as well. I am currently learning from tutorials provided by MSDN.)

Well, if by "components" you mean this, then all you will need is some version of Visual Studio (although you probably can use some other IDE if you like) and the Windows SDK (see here: http://msdn.microsoft.com/en-us/windows/aa904949.aspx ) which includes the DirectShow API.

No, I am currently working on VC++6.0, I do not hvae windows sdk, although i can install one after downloading. What I meant about components was "any specific api/classes/procedure or an example sample(if possible)"; also will SDK for Windows-7 work in XP/VS6.0??

Don't know if the Win7 version will work on XP or not, but my guess would be: no. But if you are using VC++6.0, i think that used to include the DirectX SDK and the DirectX SDK used to include the DirectShow SDK at that time when 6.0 was out so you might already have everything installed that you would need (although probably not the latest versions).
For the implementation, i don't know of any examples or somesuch, your google is as good as mine, but i think what i would try to do is to create the graphbuilder, add some video compressor filter, like DivX's to it, add a disk writer filter to it and then tell it to render the URL (i think it should be able to do it). You could -and i recommend it to- use GraphEdit to experiment with the graph until you get the correct results. GraphEdit comes with the DirectShow SDK i think.

OK, just checked my folders for "Dshow.h" it is not there. So, should I need to install DirectX SDK? Now if there is no other option, I have to inform this to my manager. So, if he says no, do I have any alternative way of accomplishing this task?

I have VS2003 installed on a virtual XP and it has DirectShow under "C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include", i guess VS6 didn't have it yet then, sorry. As far as i know the DirectX SDK no longer includes the DirectShow SDK, it has been moved to the Windows SDK, so you would need an earlier version of DX SDK, not sure which version, i think DX7 still had DirectShow, or you would need to find the platform/windows SDK for Windows XP. If this thing is important and you need to consult with your manager then i'd say, don't take my word for it and try to look around Microsoft's site for more exact information. It might prove difficult to find support for "such old versions". You can try finding 3rd party sites or look around torrent sites for older DX/Windows/Platform SDK versions but can't say how reliable those might be.

It has been difficult to search for a DirectX -SDK that contains DirectShow and that DirectX is compatible with VS6.0. I have decided to ask my manager to upgrade the VS compiler and download the Windows XP SDK, which contains DShow and compatible with the new version of VS compiler. Anyways, thanks for helping me out.

Yourwelcome and good luck.

"Examples of the types of application you can write with DirectShow include file players, TV and DVD players, video editing applications, file format converters, audio-video capture applications, encoders and decoders, digital signal processors"
