Experimental DRM+/FM decoder

drmplus's Issues

App crash (buffer overflow)

Hi again,

Just informing you that the last version does not work at all, when I am trying to open any WAV-file, I get this error:

GtkDialog mapped without a transient parent. This is discouraged.
Starting converter with ratio 1,228800 (in 156250, out 192000)

Recording for testing (result: no MSC sync)

Hi Jvan,

New 3 minutes recording (192K) from Saint-Petersburg:
https://www.dropbox.com/s/a5t2f0v69ju2j5p/DRM_20200803_073256Z.wav?dl=1
Maybe it can help.

The result is the same: no MSC sync.

Cannot build last version

Hi,

I was going to test the last version, but getting the list of errors:

drmplus/decoders/drm-decoder/frame-handler.cpp:161: error: base operand of ‘->’ has non-pointer type ‘myArray<std::complex<float> >’
                                   inbank -> element (symbol));
                                          ^~

drmplus/decoders/drm-decoder/frame-handler.cpp:204: error: base operand of ‘->’ has non-pointer type ‘myArray<std::complex<float> >’
                         fine_timeBlocks, inbank -> element (lc));
                                                 ^~

Thanks.

Incorrect labels utf-8 encoding

Hi Jvan,

Thanks for working on DRM+ decoder, there are no public available working decoders yet :)

I tried this app using IQ recording from St.Petersburg, UTF8 in labels in the app is not processing correctly, you should process symbols as UTF8, its important for displaying Cyrillic.
Change code in sdc-processor.cpp to something like this:
QByteArray ba; for (int i = 0; i < bodySize; i ++) { ba.append((char)get_SDCBits (data, base + 4 + 8 * i, 8)); } s = QString::fromUtf8(ba);

Met vriendelijke groeten.

PS: I use this file for testing https://yadi.sk/d/f6Gwin0mLKiqdg , no sound yet but probably it is not implemented. And it's also not clear how to open it, as a raw or as a wav16?
