[Bug] MP2 Native TV ATSC Scanning Error (2 Viewers)

[morpheus_xx]

This is the failing scan log

I guess this your dvb scanning that now fails morf ?

could you make sure that the user context created has the UserType enum set to : UserType.Scanner

eg.
user = new User(userName, UserType.Scanner, idCard);

you should be able to see this from a full strack trace with a debugger attached.

like in:

 public TvResult Scan(string userName, int idCard, out IUser user, IChannel channel, int idChannel)
	{
	  user = null;
	  TvResult result = TvResult.UnknownError;
	  try
	  {
		if (ValidateTvControllerParams(userName) && ValidateTvControllerParams(channel))
		{
		  StopEPGgrabber();
		  user = new User(userName, UserType.Scanner, idCard);
....

the exception occurs because of this in UserManagement.cs:

if (idChannel < 1 && user.UserType != UserType.Scanner) // EGP scanner have no channel
	  {
		throw new InvalidOperationException("idChannel is invalid");
	  }

Thanks. The problem in this case is the analog part: it does Tune() , then Scan().

I changed the user now to type "Scanner" and I can pass the check. But scanning doesn't finish yet because of a message box:
"Unable to scan"
"Generic error: An error occurred while updating the entries"

I sadly dont have analog here.
Can u get any closer to this exception?
Does it occur in setuptv?
Try make vs2010 stop on all exceptions. Both handled and unhandled.

I just want to post an update to the current situation:

Thanks to the testing support by @hardcorehire we could fix some issues already:

• Subsequent tunings failed, because the TuneRequest was re-used. The driver than did not tune again to the new frequency. (https://github.com/MediaPortal/MediaPortal-1/commit/08e96d93e544efb25851d0b0f2c15a94936292c5)
• Parsing of the LVCT was wrong, the pointer offsets where not correct https://github.com/MediaPortal/MediaPortal-1/commit/e7c0a71bf5203d1e6702155c173d5ac968aae2dd
• Analog scanning issue is work-in-progress, some fixes have been done for scanner user (https://github.com/MediaPortal/MediaPortal-1/commit/8ad850330c06cf73f06909c250f7e4277defba97)

These binaries should solve the ATSC scanning issue (see details in post above). Place them under "C:\Program Files (x86)\Team MediaPortal\MP2-Server\Plugins\SlimTv.Service" (overwrite existing ones).

Then try a new channel scan.

With these binaries I picked up some channels under the (TV Channels) which is more than I got before. But none of those preview, and it is not the full complement of channels that are available to me OTA. It didn't pick up any of the call signs. Logs attached.

ATSC Scanning worked good. Are these changes committed to the v2 branch?
I assume Gibman will work on a solution for the analog database issue.

Thanks for the all the time spent getting this working.

Last time i tried on ur comp Ididnt succeed.

 

[hardcorehire]

I installed MySQL 5.6 but not sure how to setup. I'll send password in PM.
