Title: How to detect end of stream in a DSP plugin?
Post by: krmasson on March 04, 2018, 04:28:28 am

Hello there,

I am trying to write a DSP plugin for Media Center, in order to "smartly" add silence at end of some tracks.
I started from the StutterDSPPlugin provided in the SDK.

But I see no mean of detecting the end of the stream? At first glance, I thought I could rely on the number of samples sent to CMJStutterDSPPlugin::Process() (incomplete block meaning end of stream).

It appears that the number of blocks sent to CMJStutterDSPPlugin::Process() is rather irregular: it is usually 16384, but every 3rd or 4th block, a "magic" value comes:2646, 1291 or 1796, that I was unable to correlate to some "round" number (e.g. 20000 - 16384, or 44100 - some multiple of 16384).

Any thoughts about that?

Or maybe should I use another kind of plugin? Basically, I want to add 2 or 3 blank seconds at end of stream, depending on the last few tenths of second of the sream.

Thanks in advance.
CM
