No output

[pausrn]

When I run the program he is decoding the file well. But at the end there is no output, my folder stay empty. Am I missing something? What is the output path file supposed to be?

The console output :

The compilation output :

Update : So I tried some troubleshooting (which isn't easy since I don't know anything in Pascal) and apparently it seem that the variable "length(big_img)" is equal to 0 which break the saving of the image.

Seeing a similar issue (I think).

Ran my iq file through: meteor_demod gqrx_20191018_033103_137100200.wav -o raw_iq.dat

then ran

./medet raw_iq.dat output

and got:

But no output or output.bmp.

Same issue here. Precompiled version from medet_190825_lin64.tar.gz.

Similar here. My output is:

Packets:      15 / 5259

yet I have no images. I noticed that at the end of medet_arm $decFile $outputFile -r 65 -g 65 -b 64 -d, I get no images:

no images

I am wondering if it has anything to do with Packets: 15 / 5259? If that is how many packets have been received/decoded, that seems awfully low... @oneschirm did you find any issues with your number of received packets?

Guess you figured it out but you didn't have enough valid packets to generate any image. I also had no image until the packet count became significant:
