You should not reference the VideoOS,Toolkit.dll directly it is refrenced by the VideoOS. Platform.SDK dll’s

Hi Bo,

we find the problem we had a mixed of 64 an 86 bit dll in the folder,

we replaced all the dll to a 32bit onces, and it works now,

but we still have an issue with _jpegVideoSource.Init();

from time to time we get a NULL value in this function.

after we call it, any idea what can be the reason?

The Init() has no return value so my guess is that you do a Get(). The documentation reads-

-

override object VideoOS.Platform.Data.JPEGVideoSource.Get (DateTime dateTime)

Get one JPEG at the specified time.

if no image found, null may be returned.

Parameters dateTime

Returns null or a JPEGData

class Implements VideoOS.Platform.Data.VideoSource.

Hi Bo,

we change the get(). to .GetAtOrBefore()

like in the sample that we got from the support, but from time to time we get the following exception:

error 'JPEGVideoSource:GetAtOrBefore() - State error, must call Init() first. ’

but in the code we do call init before:

                    m_log.InfoFormat("SaveJPEG (by Camera TimeDate) (3) ");
                    Item item = new Item(fqid, "item1");
                    _jpegVideoSource = new JPEGVideoSource(item);
                    _jpegVideoSource.Init();
                    object obj = _jpegVideoSource.GetAtOrBefore(dt);
                    m_log.InfoFormat("SaveJPEG (by Camera shortcut) (4) ");
                    if (obj != null)
                    {
                        JPEGData jpegData = (JPEGData)obj;
 
                        // set JPEG file name: YYYYMMDD_HHMMSS_9766928.jpeg
                        strJPEGFilename = string.Format("{0:0000}{1:00}{2:00}_{3:00}{4:00}{5:00}_CAM{6}.jpeg", dt.Year, dt.Month, dt.Day, dt.Hour, dt.Minute, dt.Second,
                                                        strCameraShortcut);

and after this errors few times we get the Following:

error ‘class std::bad_alloc: bad allocation’

and then this error:

error ‘class NmThread::CmThreadError: Error running thread!’

and at lest we get this:

error ‘Unable to connect to toolkit!’

Any idea what causing this issue?
