eu-cable support for HDHR3-4DC

[webernissle]

Support for eu-cable.

Currently it raises an exception with my eu-cable tuner: INFO | jvm 1 | 2016/05/22 00:33:21.353 | 00:33:21.301 [HDHomeRunDiscoveryReceive-37] ERROR DeviceLoaderImpl - Unable to load the capture device 'HDHomeRun HDHR3-4DC Tuner 14104392-0', id -1945501120 => opendct.tuning.discovery.CaptureDeviceLoadException: The program currently does not know how to use the channel map 'eu-cable'.

[webernissle]

The EU_CABLE is missing in the static table lookup at https://github.com/enternoescape/opendct/blob/master/src/main/java/opendct/channel/Frequencies.java

I would see a reference on wikipedia: https://en.wikipedia.org/wiki/European_cable_television_frequencies

This is not an oversight. I didn't think anyone other than people using US Cable would really have any interest in this program. I can add the tables and allow the device to be loaded, but I have no way to test and ensure it's working prior to release.

I'm also not really clear on what advantage you will get from using this software. SageTV already supports the HDHomeRun devices. Are you looking to be able to share your tuners with other software?

[enternoescape]

When OpenDCT can tune us-cable, it's because either a CableCARD is inserted which is taking care of the mappings or because a device with a CableCARD is being used as a reference for another device without a CableCARD.

If you can help me wrap my head around this a little, it will definitely speed things up.

1. Open the HDHomeRun View app and tune into any channel that you know is on cable.
2. Open a command prompt.
3. CD /D "C:\Program Files\Silicondust\HDHomeRun"
4. Get the device id's with this command: hdhomerun_config.exe discover
5. hdhomerun_config.exe <device_id> get /tuner0/streaminfo
6. hdhomerun_config.exe <device_id> get /tuner1/streaminfo
7. If you're not sure what HDHomeRun actually tuned the channel in, repeat steps 5 and 6 on every device id you got from step 4.

Post the output of the streaminfo commands. If it's anything like ATSC, I can probably work with it.

That Wikipedia page is extremely ambiguous as to what's actually relevant for this implementation. The problem is that it's basically saying everything listed is a possibility. I'm not sure if the Superband and Hyperband channels are something I should be concerned with or if the HDHomeRun could even use them. The HDHomeRun documentation says that it supports QAM annex A/C, but I can't figure out what that actually refers to. I made the changes that should be needed for your tuner to work, but I'd like to at least get the frequency table correct the first time.

[webernissle]

The main reason why I came across your solution is a pending issue on sagetv opensource with linux 64bit, EPG reading from the cable provider and native hdhomerun. Your approach is a bit different to the native driver, so I thought to have a closer look at it and to see if there is a difference with the EPG handling.

I could probably do the changes by myself, but I'm confused with the HIGH and LOW setting, this is not given, I just get 1 frequency.

I have two HDHR devices:

I live in Switzerland and the provider is UPC. I accept if it is to much effort, I would agree to stop such changes as no else is request eu_cable support so far.

I think I am about to disappoint you. OpenDCT currently doesn't parse any EPG data.

The HIGH, LOW was something I did before I realized it wasn't relevant. I'll push what I have so you can take a look.

[webernissle]

Thanks, it's not about parsing. As it works on Windows with the standard dvb-c driver for HDHomeRun it must be something how the sagetv linux native libraries interact with sagetv java parts. My main interest was to compare with a similar implementation, that is where your drivers could provide that for me.

[enternoescape]

I see. I pushed the changes to master. I was looking at how SageTV does lookups for this standard and it looks like it mostly uses exactly the same frequencies as they use in the US.

I changed this file to just use the middle frequencies like I probably should have a while ago. Let me know if we need any changes. https://github.com/enternoescape/opendct/blob/master/src/main/java/opendct/channel/Frequencies.java

If you have the JDK installed, you should be able to build your own install packages fairly easily using gradle. git clone https://github.com/enternoescape/opendct.git cd opendct ./gradlew packageLinux32 packageLinux64

The install packages will be under ./build/distributions.

[webernissle]

I get issues with compiling. Do you have some references how to build or better what is the needed environment? I tried under ubuntu with java version "1.8.0_91" (basically the SageTV recommended environment) - but I get an error /home/mwn/working/opendct/src/main/java/opendct/util/Util.java:19: error: package com.sun.xml.internal.messaging.saaj.util does not exist import com.sun.xml.internal.messaging.saaj.util.Base64;

[enternoescape]

Don't bother doing this; I removed the annoying import. You will probably need the Oracle Java JDK to compile. All of the required binaries are pre-compiled, so the JDK should be the only major thing if you're compiling for Linux. Also right now I'm in a bit of transition to FFmpeg 3.0.2 and the compiling is inconsistent between Windows and Linux while JavaCPP works out what's wrong. Those issues however are unrelated to the error you're seeing. com.sun as far as I know is only going to be present in Oracle.

0.5.5 was compiled with the changes that you requested.

[enternoescape]

I removed the com.sun import. It's not actually needed anymore. I generally try to avoid those since OpenJDK doesn't have very many of them. If you grab the latest master, you should be in business.

./gradlew clean packageLinux32 packageLinux64

[webernissle]

OK it compiles now and it finds the the tuners as well in SageTV v9.0.4! I will do more testing later but in general it works with both of my HDHR devices in Europe/Switzerland.

[enternoescape]

Excellent! My intention is to not be the headache that some projects can be to compile.
