progress of AVAssetWriter

How can I calculate the progress of an AVAssetWriter process? So if I have something like:

[assetWriterInput requestMediaDataWhenReadyOnQueue:queue usingBlock:^{

while (1){

if ([assetWriterInput isReadyForMoreMediaData]) {

CMSampleBufferRef sampleBuffer = [audioMixOutput copyNextSampleBuffer];

if (sampleBuffer) {

[assetWriterInput appendSampleBuffer:sampleBuffer];

CFRelease(sampleBuffer);

} else {

[assetWriterInput markAsFinished];

break;

}

}];

what can I be pulling (or polling) during the loop to figure out how many x of y I've completed?

Thanks.
