Re: [ecasound] Multitrack Recording via Control Interface

Hello!

Ok, I've fixed some stuff by myself but the main problem still exists.
Now I know that my chainsetup is somehow invalid thus it cannot be
connected - but no idea what's wrong.

This is the current code:

>>>>> SNIP >>>>>

...
int sources = 3; // user input
...

//--------------------------------------------------------------------------
// construct ECA control interface and configure it for recording
ECA_CONTROL_INTERFACE e;
const string current_time(getCurrentTime());

e.command("cs-add recording_chainsetup");

for (int count = 1; count <= sources; count++)
{
     const char source_no = '0' + count;
     string file_name = "./" + current_time + "-s" + source_no + ".wav";
     // the command chain
     e.command("c-add chain" + source_no);
     // the HW input source
     e.command("ai-add alsahw," + source_no + ',' + '0');
     // output file name
     e.command("ao-add " + file_name);
}

e.command("cs-select recording_chainsetup");
e.command("c-select all");
e.command("cs-is-valid");
cout << "cs is valid: " << e.last_integer() << endl;
e.command("cs-connect");
e.command("start");
cout << "Starting recording...\n";

while (1)
{
     sleep(1);
     e.command("engine-status");
     if (e.last_string() != "running")
         break;
}

e.command("stop");
e.command("cs-disconnect");
cerr << "Error: " << e.last_error() << endl;

<<<<< SNAP <<<<<

I also figured out why I didn't get any status information with
"cs-status" first (should read the manual more carefully).

This is my output:

>>>>> SNIP >>>>>

Oh, and i'm using ecasound v2.6.0.

greetings..
