Is there a way to offset the reading of the blf file? Ex: I’d like to start reading the blf from 1 minute after the beginning of the file. I tried changing the Engine.startTime which changed when my av_source_reader started reading from, but BLFFileReader doesnt seem to respect this setting. I thought maybe the BLFFileReader.offset property would do this but it only seems to offset the timestamps of the frames themselves?
