I want to convert video files(.wmv and .avi) uploaded on my site to get converted to .flv. Searching the web I found ffmpeg(http://ffmpeg.mplayerhq.hu/) is a command line software which does the required conversion. But i don't know if it can be used with .NET. If it can be used then how..? If not then what is the other solution...?Can anyone help..?

You can start any process from .NET with process.start. ASP.NET obviously has nothing to do with the process of the actuial conversion

thanks for the reply Christian,
I got it .... to do the same i have found an executable called ffmpeg.exe. can you tell me exactly what parameters do i need to pass and how do i use it in my asp .net project using c# such that the generated .flv video is of same dimension and quality as the original avi video. Following may be useful to you.
download ffmpeg.exe (http://ffdshow.faireal.net/mirror/ffmpeg/)
FFmpeg Documentation (http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html)
download ffmpeg.c (http://svn.mplayerhq.hu/ffmpeg/trunk/)

Hey its working for me. There are some sites e.g. http://www.mediasoftpro.com/ where they give already built dll which we can easily implement in our project. All such dlls are actually wrapper to the free tool ffmpeg.exe which can convert videos and audios from one format to another. So i thought to use the tool itself instead of the wrapper dll. I have tried very simple example n its working for me so thought to share it it with all.
Download ffmpeg.exe from (http://ffdshow.faireal.net/mirror/ffmpeg/). you will get a dll along with it (pthreadGC2.dll) keep both the exe and this dll together.
FFmpeg Documentation (http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html) will be required for the syntax.
If you run it via command prompt then this is the syntax
ffmpeg -i inputfilename outputfilename
If it is to be executed via .net then follow what Christianhad suggested in the post before. Process.Start can be used to execute an executable.Do remember to give write permission to the asp worker process on the folder where the resultant flv file will be saved. If you dont then the program will run without any error or warning but output file will not be produced.
One more thing it do not convert .wmv files to .flv . Is there any way out to it........?

What you're looking for is called a master detail view. I would usually use nested repeaters to create such a view, because of the control you get when using them. However, there is a bunch of google[^] hits on doing it in a gridview, I'm not sure if they will help tho, because you want the edit template to show the detail view ? You may need to roll your own solution with a repeater, I'm not sure.

OK - to reiterate what I've said before: read your book. Giving me a link to your local machine won't work, localhost on my machine is MY file system. Not yours.

this sort of thing you can do only in your system.

Have you any idea about DataRelation?
If yes follow following code
DataSet ds=
DataRelation dr = new DataRelation("new_relation",ds.Tables[0].Columns["PKey"],dst.Tables[1].Columns["Pkey"]);
ds.Relations.Add(dr);
parentGridView.DataSource=ds.Table[1];
parentGridView.DataBind();
Now onRowDataBound event of parent gridview
GridView rp = (GridView)(e.Row.FindControl("ChildGridViewID"));
rp.DataSource=((DataRowView)(e.Row.DataItem)).CreateChildView("new_relation");
rp.DataBind();
bEst regard

Link to a page which takes the filename off the URL and does a Response.BinaryWrite to send the file into the browser to be displayed.

This is a sure sign that your overall design is broken, because it's working when your code can assume that the client is the server.

If you are using Response.AppendHearder("Content-Disposition"........) remove it, it will be open in same window and will not give you any popup. Add all the content to Response.BinaryWrite(byte[],offset,count);
