[Discuss-gnuradio] Difficulty with File Meta Source block

2014-06-20 Thread dushyant.marathe
Hi all, I want to use "File Meta source" & "File Meta sink" block from Gnu Radio. My flow graph configuration is as follows : signal source (sine wave) -> throttle -> Meta file sink (Output.out) Using above configuration I am able to write meta

Hi Activecat, Thanks for the reply. I am playing wav file using windows media player. When I execute the flow graph it writes wav file. Wav file's size increases, unless I stop the flow graph. But when I played it using media player it doesn't play any more. Also I am ensuring that amplitude is

Hi Activecat, I used both "Head" and "Skip Head" blocks in parallel to separate out multiplexed input stream. The Head block correctly gives me first 240k elements but, "Skip Head" block doesn't give me any elements after skipping 240k elements. For your reference I have attached image of my flow

Hi Activecat, Thanks for the reply. As suggested by you, I used "Stream Mux" and it worked for me. Now I want to de-multiplex the output of "Stream Mux" so as to get back both the inputs separately. If you have any suggestions, please let me know. Thanks and Regards, Dushyant -- View this

Hi all, In my flow graph I am using two different inputs. At particular time, only one input is selected. For this I am using 'Selector' block with two inputs and only one output. I want to change 'input index' of 'Selector' block when flow graph is running. I used 'WX GUI Slider' block, it works
