  Not Finding Channels
Posted by: Tigeraif - 2019-08-06, 08:03 AM - Forum: Legacy (v4.x and earlier) - Replies (5)

Hi

I have an Avermedia A835B AVerTV Volar Green HD attached to my laptop in a dorm room connected to an external antenna via a wall socket.

I have NextPVR installed. NextPVR sees the tuner but when I do a channel scan no channels show up.

When I checked the logs I found the following:

<tuning>
<type>DVB-T</type>
<locator>
<frequency>177500</frequency>
<bandwidth>7</bandwidth>
</locator>
</tuning>

2019-08-06 16:28:29.781 [DEBUG][1] Switching BDA graph to tune:

The line I am interested in is the following:

2019-08-06 16:28:24.743 [DEBUG][8] locked=0, present=1, strength=10, quality=10 (took 0ms to check)

Does this mean I have good antenna strength and quality?

If so why am I not seeing any channels?

I would appreciate any help.

Thank you.

Is there any way of making a m3u list for NextPVR to use with my Happauge Colossus 2 capture card?

Thanks.

  Can't watch live tv in chrome
Posted by: drmargarit - 2019-08-05, 05:07 PM - Forum: Linux - Replies (7)

I reinstalled nextpvr a few days ago using the .deb instructions.
I can record and playback recordings but livetv fails.
I thought it might be a permissions issue but I changed the live tv directory to be the same as the recordings directory and it didn't help.

VLC cannot play live tv either.

Code:
Your input can't be opened: VLC is unable to open the MRL 'http://192.168.86.25:8866/live?channel_id=7149'. Check the log for details.

NextPVR Logs attached...

Wierd....
I was going to attach the vlc log also. Vlc doesn't log unless you turn on logging. Turned on logging and tried to stream. Failed again and no log. Killed vlc, restarted it and now it plays the stream. Nextpvr now plays live streams too. Computers :mad:

  Desktop App Guide
Posted by: jcole998 - 2019-08-05, 01:48 PM - Forum: Windows - No Replies

Just tried to change the channel group in the desktop app. No joy. List of names is presented but selecting one does nothing. Can only escape out.

Is this not yet active?

  Unable to scan channels with HDHR3-DT
Posted by: nicwithsticks - 2019-08-05, 11:49 AM - Forum: macOS - Replies (5)

I'm having trouble getting the my HDHR to scan channels. The tuners are detected, but no channels appear when I click the "Scan Channels" button.

I noticed this error in red when scrolling back through the Terminal window:

[INDENT][COLOR="#FF0000"][25] Unexpected error in legacy scan: Newtonsoft.Json.JsonReaderException: Error reading JArray from JsonReader. Current JsonReader item is not an array: Null. Path '', line 1, position 4.
at Newtonsoft.Json.Linq.JArray.Load(JsonReader reader, JsonLoadSettings settings)
at Newtonsoft.Json.Linq.JArray.Parse(String json, JsonLoadSettings settings)
at NShared.Recorders.HDHomeRunScanner.LegacyScan(HDHomeRun device, Dictionary`2 parameters, String& reason)[/COLOR][/INDENT]

Is anyone else having this issue? Have I missed a step?

I've attached my logs, too.

  Programming using v5 commands. How to login?
Posted by: drmargarit - 2019-08-05, 01:14 AM - Forum: Other Clients - Replies (15)

I have a ton of utilities and a client that I am dragging up to v5 compatibility. All of them currently read and/or modify the database directly and I am trying to get away from that using the http calls.
I know you are super busy and I'm trying to bug you as little as possible.Wink Right now I am trying to learn by reproducing the calls that the web client makes.
My question is this: Do I need to login to use calls like: "/services/service?method=channel.list&format=json"? or is logging in irrelevant for applications?

When the web page logs in, it gets a return code of 302.
When I login using the code below, I get a return code of 200. Yet, I can get a channel listing.
So, I am confused at this point. Did I login successfully? Do I need to login at all? Did I get the channel listing because I am already logged in with the web interface in chrome? How do I log out?

Code:
//function doLogin() //{ // var salt = getParameterByName("salt"); // var username = $("#email").val(); // var password = MD5($("#password").val()); // var combined = MD5(salt + ":" + username + ":" + password); // window.location.href = 'login.html?hash=' + combined; //} public async Task<bool> doLogin() { string url = "http://192.168.86.25:8866"; try { //login fHttpResponseMsg = await fHttpClient.GetAsync(url); fHttpRequestMsg = fHttpResponseMsg.RequestMessage; string query = fHttpRequestMsg.RequestUri.Query; var parts = HttpUtility.ParseQueryString(query); string salt = parts.Get("salt"); string passMD5 = CreateMD5("password").ToLower(); string hash = CreateMD5(string.Format("{0}:{1}:{2}", salt, "admin", passMD5)); hash = hash.ToLower(); string loginRequest = string.Format("{0}/login.html?hash={1}", url, hash); fHttpResponseMsg = await fHttpClient.GetAsync(loginRequest); fHttpRequestMsg = fHttpResponseMsg.RequestMessage; //get channel listing string serviceRequest = string.Format("{0}/services/service?method=channel.list&format=json", url); fHttpResponseMsg = await fHttpClient.GetAsync(serviceRequest); string json = await fHttpResponseMsg.Content.ReadAsStringAsync(); return true; } catch { return false; } } public static string CreateMD5(string input) { // Use input string to calculate MD5 hash. Cut and paste from Stackoverflow using (System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create()) { byte[] inputBytes = System.Text.Encoding.UTF8.GetBytes(input); byte[] hashBytes = md5.ComputeHash(inputBytes); // Convert the byte array to hexadecimal string StringBuilder sb = new StringBuilder(); for (int i = 0; i < hashBytes.Length; i++) { sb.Append(hashBytes[i].ToString("X2")); } return sb.ToString(); } }

Thanks for your help!
