How can I set properties of encoders used in TimeShifting object?

There are 2 ways to do that:

1. Use GetVideoCodecProps() and SetVideoCodecProps() methods.

This methods use ICGetState interface of codecs ( http://msdn.microsoft.com/en-us/library/dd743157(v=VS.85).aspx ). That means that they get and set properties in binary structure and it is impossible to change them manually (data storing format is specific for each codec).

So, here is a sequence of actions to use them:

- set all needed codec settings through property page.

- get state (settings) with GetVideoCodecProps() method.

- save received settings.

- on next usage restore this settings with SetVideoCodecProps() method.

Note: ICGetState is supported by VCM codecs only (they are marked as blue in GraphEdit). Edit).

2. Receive pointer to codec object and use it's DirectShow interface directly.

Here is a sequence of actions:

- create an instance of codec DirectShow interface (must be provided by codec developers).

- get the pointer to codec object with GetVideoEncoderFilter() or GetAudioEncoderFilter() method.

- cast codec object to it's DirectShow interface instance.

- use DirectShow interface instance methods to set codec properties.

Note: This method is supported by non-VCM codecs with DirectShow interface only.
