Error: no input DVB signal after 5,000 milliseconds #675

Open RolsimGit opened 3 years ago

RolsimGit commented 3 years ago

First of all many thanks for disclosing the sources. This is not a matter of course.

I have the following problem:

Hardware : Hauppauge HVR 4400 Develop : Visual Studio 2019

With the parameters

tsp -O file test.ts -P until --seconds 20 -I dvb --delivery-system DVB-S2 --lnb Astra --frequency 11493750000 --polarity horizontal --symbol-rate 21995000 --device-name :1

I get a stream.

but I cannot get a stream in my own program

What I have not understood?

lelegard commented 3 years ago

In your modulation parameters, I see this:

satellite_number    {_access=0x014f2718 {1} _data=0x014f2718 "\x1" }    ts::Variable<unsigned int>

Do you have a DiSEqC switch and do you target the second port?

Otherwise, let this field unset (or set to zero) and retry.

RolsimGit commented 3 years ago

The same result, even if not initialized, or with value 0 or 2.

lelegard commented 3 years ago

OK, the other two differences with the command line are:

What are the exact characteristics of this transponder? Which satellite is this?

lelegard commented 3 years ago

Also try tsp --verbose on the command which actually grabs the signal to view the actual parameters.

And then what ? Does the application work with the same tuning parameters as the tsp command ?

RolsimGit commented 3 years ago

It is Astra 19.2 The parameters are from the NIT

RolsimGit commented 3 years ago

No Stream with the new Parameter

RolsimGit commented 3 years ago

I have found the reason.

grafik

When selecting the DeviceName I had the following code:

`void CDlgTuner::OnSelchangeCmbTuner() { int i = 0; bool erg;

CComboBox* cmbBox = (CComboBox*)GetDlgItem(IDC_CMB_TUNER);

i = cmbBox->GetCurSel();

if (theApp.m_pTuner->isOpen()) theApp.m_pTuner->close(*theApp.m_pReportFile);

erg = theApp.m_pTuner->open(m_tunerVector[i]->deviceName(), false, *theApp.m_pReportFile);
...

}`

A new opening of the tuner is apparently not enough. The new functional code:

`void CDlgTuner::OnSelchangeCmbTuner() { int i = 0; bool erg;

CComboBox* cmbBox = (CComboBox*)GetDlgItem(IDC_CMB_TUNER);

i = cmbBox->GetCurSel();

ts::UString deviceName = m_tunerVector[i]->deviceName();

if (theApp.m_pTuner->isOpen())
    theApp.m_pTuner->close(*theApp.m_pReportFile);

delete theApp.m_pTuner;

theApp.m_pTuner = new ts::Tuner(theApp.m_duck, deviceName, false, *theApp.m_pReportFile);
erg = theApp.m_pTuner->open(deviceName, false, *theApp.m_pReportFile);
...

}`

lelegard commented 3 years ago

A new opening of the tuner is apparently not enough.

OK, I will check.

lelegard commented 3 years ago

I have made a test closing / reopening the same ts::Tuner object and it works. I have currently only one tuner to test and close / reopen is done on the same tuner device, so the test a bit different. But looking at the source code, I see no reason why a close / reopen should not work.

Test done on Windows 10 20H2, VS 2019, current TSDuck repo state (3.24-2103).

Which version of TSDuck are you using?

RolsimGit commented 3 years ago

I'm using TSDuck-Win64-3.23-1965.exe.

I will install the latest one. I report then.

lelegard commented 3 years ago

I do not think it will change anything. I was wondering if you were using some very old version. But this is not the case.

RolsimGit commented 3 years ago

hmmm... look here

https://tsduck.io/download/tsduck/

lelegard commented 3 years ago

Yes, 3.23 is the latest official version. When I say "latest repo", I mean the current state of the source code in the git repo.

You can find nightly builds of beta versions here: https://tsduck.io/download/prerelease/

But, again I do not think this will solve your issue. There is no significant difference in the way tuners are opened and closed.
