When I first use rtmpdump to download "rtmpe://" stream to local file system files,it works very well.
but if I close it when the download percent comes to 1% more or less, and then I try to resume the previous download process with the more arguments '-e',mostly I will get a failure with tips of such words listed as below(of course , sometimes it doesn't fail ,I am thinking that maybe this has much with the previous download percent value,is this right ?):

"Last tag size must be greater/equal zero (prevTagSize=-1919074145) and smaller then filesize, corrupt file!"

To rtmpdump,why this happens,how to avoid this,and does this mean rtmpdump.exe supports broken-after-resume download not very well or perfectly?
I know one project directly from rtmpdump.exe named flvstreamer,and it seems to do better at this point.So,what way goes in detail?
