Just a gentle reminder, I didn't receive anything from your side, I assume my problem definition was quite vague and I didn't explain the exact scenario. So I'm trying again to give you guys a more clearer picture.
I'm currently using GNU Radio Companion tool to develop a flow graph which looks like this (please find the below screenshot)
As you can see here, I'm using File Source Block which takes IQ file as source(this file contains all the IQ data. approximately of 3GB) and in the the File Sink I'm just storing all the IQ data in a output.txt file. As per my requirement, I need to implement a functionality which controls the content of file source through the sliding bar or progress bar i.e. if IQ file is read only 50% then slider should move to 50%. I have tried different approach and searched on the internet but couldn't find any workaround through which I can manipulate the File Source Block. Just a quick update I'm doing my project in python and would like to implement this feature in the same source code.
It seems like the Seek() function in the API is not behaving as expected. Could anyone please suggest me a way to achieve this functionality if it is possible. Looking forward to the positive response and thanks in advance.
Thanks & Regards
