SharpCap Forums

Hi,

I've been going around in circles trying to debug a script & I have finally narrowed it down, I think.

I have been using:
to programmatically limit the Camera Capture in seconds, i.e.:
Oddly, now I am getting an error, this from SC Log:
I had a script using this perfectly just a couple of days ago but since then I have installed the SC 3.2 BETA

Is this a known bug in the BETA or some odd issue my end?

Cheers..,

Hi Kirk,

this is a change in 3.2 - previously CaptureLimitValue was used for both number of frames and times. Now there are two separate values to set

CaptureLimitCount (for number of frames, an integer)
CaptureLimitTime (for setting the time length of a capture - this is a TimeSpan)
hope this helps,

Robin

from System import TimeSpan
SharpCap.SelectedCamera.CaptureConfig.CaptureLimitTime = TimeSpan.FromSeconds(100)

Thanks Robin, I assumed it was maybe something along those lines, I must have missed it in the documentation.

So just to get this straight with the new TimeSpan attribute, is the capture time in seconds the value held in the parenthesis i.e. 100 in your example?

I am guessing too that all pre 3.2 scripts using CaptureLimitValue will need to be changed & from that point on will only function on 3.2 and above?

Is there somewhere an exhaustive list of all the numerous SharpCap attributes etc.... with explanations?

I see a limited few on the Scripting Help Page but I have mainly been finding them by using the scripting console by using the suggestion list.
This is fine and some have self explanatory names but it’d still be nice to see a glossary.

I've found an answer to my TimeSpan question: https://docs.microsoft.com/en-us/dotnet ... work-4.7.2

Hi,

now at the stage to implement this change in my script but just need to check something quickly.

At the moment in v3.1...... a capture sequence is scripted as:
where X = (seconds)
or where X = (number of Frames)

In this new version do I omit this line?: and purely place either?: or regards..,

SharpCap.SelectedCamera.CaptureConfig.CaptureLimitType = CaptureLimitType.TimeLimited/FrameLimited

and purely place either?:

SharpCap.SelectedCamera.CaptureConfig.CaptureLimitTime = TimeSpan.FromSeconds(X)

or

SharpCap.SelectedCamera.CaptureConfig.CaptureLimitCount = X

Solved it, the 'CaptureLimitType' line does need to stay as in previous version, it is only the 'CaptureLimitValue' line that is altered depending on whether Time or Frames is set as the Limit.

So, this is clearly an issue I had not anticipated for those using scripting. I originally removed the CaptureLimitValue in SharpCap 3.2 and replaced it with two separate properties because the use of CaptureLimitValue for both count and time led to some ugly and hard to maintain code within SharpCap itself.

I am therefore going to re-instate the CaptureLimitValue property for compatibility reasons with existing scripts. Internally I will flag it as 'obsolete' and will not use it within SharpCap code. What it will do is set or retrieve either CaptureLimitCount or CaptureLimitTime (depending on the CaptureLimitType set).

cheers,

OK,

so in my script now I have a check for version number and depending on result i.e. pre v3.2 it reverts to the ‘old’ properties or if it finds version is 3.2 or above it uses the ‘new’ properties.

Can I still use this as I have implemented?

Yes, of course - just hoping to save others from having to jump through the same hoops that you have had to.
