Video Codec Latency API

ImageCodecGetDecompressLatency

Retrieves the video latency from the specified video codec.



 
pascal ComponentResult ImageCodecGetDecompressLatency(ComponentInstance 

                                            ci, TimeRecord * latency);

ci: Specifies the image compressor component for the request.
latency: Pointer to a time record containing the latency required for that codec.

DISCUSSION

The following code snippet shows an example implementation of this function:



 
pascal ComponentResult myCodecGetDecompressLatency(myCodecGlobals *glob, 

                                                    TimeRecord *latency)



 
{

    OSErr   result = paramErr;

    

    // Example setting 33 ms latency

    if (latency != nil) {

        latency->value.hi = 0;

        latency->value.lo = 33;             // latency value

        latency->scale = 1000;              // 1 ms scale

        latency->base = nil;

        result = noErr;

    }

    return result;

}
