Accessing selected video processors

Hi Adnan,

Thanks for the reply.

I have added two filters named “"LEAD Video Dynamic Rate Control Filter" and "LEAD Video Text Overlay Filter (2.0)" using Video Processors option. But when I am trying to change the properties of each filter, getting error message as “Object reference is not set to an instance of an object”. Please find the attachment herewith the post, which contains the code snippet I am using to add filters.

Please suggest how can I dynamically set the properties of applied filters?

Kiran,
Our moderator split this post into a new thread because it has a new different question.
The main error is that you're not passing the correct index value to the GetSubObject() method.

Calling GetSubObject(PlayObject.SelVideoProcessor) only gives you the first added processor. To access other processors, you must add offset as follows:
GetSubObject(PlayObject.SelVideoProcessor + offset).

Here are more details:
When you add a video processor, it will be appended as the last video processor in the list.
When you call the GetSubObject method, you need to point to the correct index as follows:
... = playCtrl.GetSubObject(PlayObject.SelVideoProcessor + (playCtrl.SelectedVideoProcessors.Count - 1)) as .....
This will only work if you keep the Add and GetSubObject methods together. If you intend on adding the video processors in one place then access the properties of each processor in another, you need to check the SelectedVideoProcessors list and give the correct index to the GetSubObject Method.

Hi Adam,

Its working fine now,
