Another Channel Changing Question

clutch2sft · 2021-09-21, 11:18 PM

First let me say thank you for this software. So far it has been very easy to setup and use. I have read about all the threads I can find on the subject and can't figure this one piece out.

Setup - HDPVR with DTV STB. I can't get IR blasting to work without NextPVR so gave up and wanting to just use IP over the network.

It seems no matter what I put in the two fields for the setup - I can't make it work ... though I can change channels all day long at the command prompt.

calling "C:\Program Files (x86)\GnuWin32\bin\wget.exe" "http://192.168.66.186:8080/tv/tune?major={channel} "

Also moved those things to batch file and just called the batch file with {channel} but nothing works. Although the logs would lead you to believe it is calling the program.

Any ideas?

If you're wanting to run a batch file, you'd typically run

c:\windows\system32\cmd.exe /c c:\path\to\my.bat

If you're running an executable, then it wouldn't need to run via cmd.exe

If you don't specify any arguments, it'll default to passing in the channel number. Alternatively, you can specify whatever args you need, and {channel} would be replaced with the channel number.

Quote:2021-09-21 18:00:56.160 [INFO][4] Running blaster: c:\windows\system32\chchannel.bat 4

This likely didn't work because it is a bat file and needs to be run via "c:\windows\system32\cmd.exe /c"

Quote:2021-09-21 17:55:01.281 [INFO][5] Running blaster: "c:\windows\system32\cmd.exe" "/C chchannel.bat 7"

This likely didn't know where chchannel.bat was. ie, if you'd explicitely specified the full path to chchannel.bat, then it probably would have worked.

Weird. Not sure what that does, if anything.

ie, I'd try either
"c:\windows\system32\cmd.exe" "/c c:\path\to\my.bat {channel}"

or
"C:\Program Files (x86)\GnuWin32\bin\wget.exe" "http://192.168.66.186:8080/tv/tune?major={channel}"

Thank you for taking the time to respond. Work took me away for a while - but I thought I had tried most of the iterations you were suggesting. I ran through them again just to see.... none of these seems to work. Maybe I am missing something simple on my side?

It looks like maybe you're entering quotes where there shouldn't be.

ie, should be:
c:\windows\system32\cmd.exe
/c c:\users\public\chchannel.bat {channel}

or:
C:\Program Files (x86)\GnuWin32\bin\wget.exe
http://192.168.66.156:8080/tv/tune?major={channel}

Don't put quotes around those when you're entering them.

That was it! Thank you for looking at this and the quick response. To complete the thread for other reading .... I did note that it was necessary to to restart the nextpvr service after each change to the blaster program under the device ... before the change was recognized.
