[Discuss-gnuradio] About sample lost |

Dear list,
Now I meet a problem about counting all the input
samples. I hope I can get some assistant from here. The problems are as
follows,
In one of my blocks, I want to count all the consumed input
samples to get the timestamp of the received packet. I have used GPS to
synchronize two usrps and therefore for the same packet the two usrp
should consume the same amount of samples in this block from the
beginning of the stream. At the very beginning, it works fine but after
it works for a while the timestamp in one usrp will lost 8192 samples
(8192 samples less than the other one). I have checked it is the same as
the maximum output buffer of one block.
I want to ask if it is
possible that because the block can not process the sample as fast as
the output from the previous block, one buffer of samples are
lost. BTW I did not find any indicator of overflow from uhd when I run
the code.
Any suggestions would be appreciated.
Best regards
Zan
