...eal with a backlink in the granulepos itself ? For reference, my data packets start with start granule, end granule, backlink granule, all 64 bits, so picking the granule is just a simple constant offset lookup into the data packet, eg, you replace: backlink = granulepos<<32; by backlink = read64le(op.packet+constant_offset); Hardly complex. > decoders to find all the relevant data.

We've generally designed the seeking algorithm so it can be implemented without looking inside the packets beyond looking up the samplerate in the first few packets. And you can repeat...
