Retrieving duration of an uploaded video

#1

Hi,

I have a requirement as a part of an import routine I am writing to get the duration of the uploaded video so this value can be stored on a local database.

I am using the following code to do the upload and this is working fine, the duration of the video is visible in the KMC when I look at the details for the video:

FileStream fileStream = new FileStream(context.Server.MapPath("~") + @"" + fileName, FileMode.Open, FileAccess.Read);

                    KalturaClient client = new KalturaClient(GetConfig());
                    string ks = client.GenerateSession(ADMIN_SECRET, USER_ID, KalturaSessionType.ADMIN, PARTNER_ID, 86400, "");
                    client.KS = ks;
                    KalturaUploadToken uploadToken = client.UploadTokenService.Add();
                    client.UploadTokenService.Upload(uploadToken.Id, fileStream);
                    KalturaUploadedFileTokenResource mediaResource = new KalturaUploadedFileTokenResource();
                    mediaResource.Token = uploadToken.Id;
                    KalturaMediaEntry mediaEntry = new KalturaMediaEntry();
                    mediaEntry.Name = ds.Tables[0].Rows[0]["Synopsis"].ToString();
                    mediaEntry.ReferenceId = prefix + "-" + objectid;
                    mediaEntry.MediaType = KalturaMediaType.VIDEO;
                    mediaEntry = client.MediaService.Add(mediaEntry);
                    mediaEntry = client.MediaService.AddContent(mediaEntry.Id, mediaResource);

When I then go to the mediaEntry object to get .Duration it is always 0.

Any ideas please?

Thanks,
Steve

Hi Steve,

The KalturaMediaEntry object has the members:
duration
msDuration

I could not reproduce a situation in which they show 0 whereas the file actually has duration.
Does msDuration also return 0? can you share your code?

Hi Jesse,

Thanks for your reply. Yes both duration and msDuration return 0. My code is pasted below

try

{

string fileName = HttpContext.Current.Request.QueryString["FileName"].ToString();
fileName = SanitizeFileName(fileName);

using (FileStream fs = File.Create(context.Server.MapPath("~")  + @"\" + fileName))
{
    Byte[] buffer = new Byte[32 * 1024];
    int read = context.Request.GetBufferlessInputStream().Read(buffer, 0, buffer.Length);
    while (read > 0)
    {
        fs.Write(buffer, 0, read);
        read = context.Request.GetBufferlessInputStream().Read(buffer, 0, buffer.Length);
    }
}


string objectid = HttpContext.Current.Request.QueryString["objectid"];
string objectTypeid = HttpContext.Current.Request.QueryString["objectTypeid"];
string prefix = HttpContext.Current.Request.QueryString["prefix"];

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Database"].ConnectionString);

// Get details saved already for this video which are then used
// when importing the video
SqlDataAdapter da = new SqlDataAdapter("Select * from tbl_D2_Object where objectid=" + objectid + " and objecttypeid=" + objectTypeid, conn);
DataSet ds = new DataSet();
da.Fill(ds);

if (ds.Tables[0].Rows.Count > 0)
{

    FileStream fileStream = new FileStream(context.Server.MapPath("~") + @"\" + fileName, FileMode.Open, FileAccess.Read);


    KalturaClient client = new KalturaClient(GetConfig());
    string ks = client.GenerateSession(ADMIN_SECRET, USER_ID, KalturaSessionType.ADMIN, PARTNER_ID, 86400, "");
    client.KS = ks;
    KalturaUploadToken uploadToken = client.UploadTokenService.Add();
    client.UploadTokenService.Upload(uploadToken.Id, fileStream);
    KalturaUploadedFileTokenResource mediaResource = new KalturaUploadedFileTokenResource();
    mediaResource.Token = uploadToken.Id;
    KalturaMediaEntry mediaEntry = new KalturaMediaEntry();
    mediaEntry.Name = ds.Tables[0].Rows[0]["Synopsis"].ToString();
    mediaEntry.ReferenceId = prefix + "-" + objectid;
    mediaEntry.MediaType = KalturaMediaType.VIDEO;
    mediaEntry = client.MediaService.Add(mediaEntry);
    mediaEntry = client.MediaService.AddContent(mediaEntry.Id, mediaResource);


    string videoid = mediaEntry.Id;
    string thumbnail = mediaEntry.ThumbnailUrl;

    string status = mediaEntry.Status.ToString();
    int duration = mediaEntry.Duration;
}

}

Thanks,

Steve

Hi Steve,

I believe the issue is that you are checking duration too soon after uploading the entry.
Can you try running:
mediaEntry = client.MediaService.Get(entry_id);
After the entry is in status ready and see what the result is?
