@ZeChico thank you for replay but unfortunately it won't fit my needs. I use rtmpdump to record live stream and use it like PVR in XBMC, in case or merging file I'd need to record whole at first, then merge and play - using only rtmpdump I can watch content with a delay of 10 secs. Resuming seems to be the only one problem and eventually I'll probably try to implement this in rtmpdump but wonder if change could be done in release version so everyone can benefit from it.
