cannot view previously captured files interactively with ifile directive

[jamesleytevidal]

Hi there,

in previous versions of dump1090 (non-fa), I was able to capture signals with the rtl_sdr utility to a file, and play those back with dump1090 using --ifile. When I do this with this version of dump1090, the interactive interface comes up but no flight data is populated.

I tried the --iformat UC8 argument with it as well with no difference. I can use --interactive live with an rtl-sdr dongle and get data, so this seems to be an issue only when supplying an input file.

What am I missing? is there another argument I need to supply?

How did you capture the data?
What's the command line you're trying to use to read the data?

capture was originally performed with the rtl_sdr utility.

Looking back through some old tickets, I think we've figured out what's going on - sample rate in the original captures was 2000000, new captures at sample rate of 2400000 render fine. So we have a way to deal with it, we just need to recapture the data. Closing.

Thanks!

Ah yep that'd do it - the 2MHz demodulator was replaced with the 2.4MHz one quite a while ago.
