Playing Videos - Part II

Friday, September 26, 2008

In Playing Videos-I I have been explained to upload a videos, how convert video from one format to another format and how to generate thumbnail automatically. In this post I am going to expalin how to retrive the videos and thumbnail dynamically from database.

First I am starting with DataBase part, Here I am creating a table called videos. And it contains 3 fields the are
Video_ID,Video_File,Video_Image. You can see the table design pic.

Here "Video_File" field contains Name of the video with extension. Here I am going to store the file name only. But the video file is located in server. "Video_Image" is the thumbnail file name with extension. Same as video thumbnail also located in server.

When I am uploading video, I am going to save the videofilename, Image name in database. Here I used very simple code to insert this details. Here is the code.....

private void Savedetails()
string filename, imgname;
filename = Session["outputfile"].ToString();
imgname = Session["thumbname"].ToString();
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["TestConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("insert into video(Video_File,Video_Image) values('" + filename + "','" + imgname + "')", con);

You can use stored procedures in back end for the better performance. Once the video uploading is finished then I am going to show these details in DataList. Here is the code to bind the video thumbnail in Datalist

<asp:DataList ID="dtlstVideo" runat="server" GridLines="Vertical"
RepeatColumns="2" RepeatDirection="Horizontal" BackColor="White"
BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="5">
<td><a href="Play.aspx?vid=<%# DataBinder.Eval(Container.DataItem, "Video_ID") %>">
<img src="Video/Thumb/<%# DataBinder.Eval(Container.DataItem, "Video_Image") %>" border="0" />
<FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
<AlternatingItemStyle BackColor="#DCDCDC" />
<ItemStyle BackColor="#EEEEEE" ForeColor="Black" />
<SelectedItemStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />

when the user click on the datalist it will be redirected to play.aspx with video ID as the query string. In the
play.aspx page I am goign to bind the SWF player with video file name. Here is the code...

string vid,vfname;
protected void Page_Load(object sender, EventArgs e)
vid = Request.QueryString["vid"].ToString();
DataSet dst = (DataSet)Session["videods"];
DataRow[] dw = dst.Tables[0].Select("Video_ID= '"+ vid +"'");
if (dw.Length > 0)
vfname = dw[0]["Video_File"].ToString();
string plyr = "<embed src='Players/flvplayer.swf' width='425' height='355'
bgcolor='#FFFFFF' type='application/x-shockwave-flash'
flashvars='file=Video/SWF/" + vfname + "&autostart=false&frontcolor=0xCCCCCC&
plh.Controls.Add(new LiteralControl(plyr));

You can see the screen shot of playing a video dynamically..

Hi Ramky,

Great could the same thing be accomplished if you were to store the video file in the database instead of on the server?

Hey Guys,
Please find all links related to this post....

Please note that this was developed 5 years back. You may be found new version of ffmpeg so use this code for just reference purpose...
