Re: OpenADefaultComponent for Audio

Hi ,

In my audio encoding application (with SCAudioFillBuffer API ) I am using OpenADefaultComponent for creating a componentInstance.

OpenADefaultComponent(StandardCompressionType, StandardCompressionSubTypeAudio, &ci);

I call OpenADefaultComponent few times to query the names of codecs, creating a componentInstance for each codec etc and then for final Encode. The first time I do this, everything works just fine with proper encoded output.

But when I do the whole thing again (for second encode) , OpenADefaultComponent always returns me -108 (iMemFullErr) and sets ci=NULL. I have sufficient RAM in my system. When I re-launch the application again, the first encode goes fine and after that OpenADefaultComponent starts returing -108.

What could be going wrong here ? I am calling CloseComponent for every OpenADefaultComponent call. Is there anything else I need to free/initialize? Has anyone else faced this issue before ?

QuickTime Player opens that component repeatedly without ill effects. You can open it repeatedly in WhackedTV sample code as well. I think you need to look elsewhere in your code.
