Modifying the video and audio stream

Hello,
It's possible to modifying the video and audio stream the by using DVB-Dream modules. It has an API like this:

Code: Select all

BOOL StreamCallback(unsigned char *InBuf, int InLen, void *pOutBuf, int *pOutLen): BOOL;
Is possible the same action with ProgDVB modules or even plugins?
I need access to TS/188 and then modify it. After that ProgDVB should use this modified stream instead of the original one.
Is there any sample for this purpose?

Thanks for your time.

No API for that. What modification you like do?

To override the built-in CSA module of ProgDVB.
Currently MD-API plugins send DCWs to ProgDVB and then it uses them to do the final decryption of the audio and video stream (using the built-in CSA module). I want to do this step myself and I want to replace it with a custom algo such as DES. So I need a stream callback like this to control the process.

Code: Select all

BOOL StreamCallback(unsigned char *InOutBuf, int InLen)
