ATSC EPG - Possible Implementation Strategy?

J.J. Smith · 2012-11-21T20:56:44+00:00

TVHeadend has made a lot of exciting progress recently, but developers have (pragmatically) focused on their local broadcast standards. For TVHeadend to beco...

Jim DiCarlo

Your right tvheadend did launch it (it was not launched till I did that), but what is the default user and password? Usually there isn't but on this version there is.

Thanks for all your help

Jim

EDIT: in the terminal I get this error (in red)

2015-03-25 19:01:13.010 [ ERROR] access: No access entries loaded

Is this why I cannot log into it?

Steve Smith

Jim: I had forgotten all about this. You need to kill the running tvheadend then again start the service with the "--firstrun" option. If you run the command "tvheadend --help" you will see a list of the available commands and that may help you with further problems.

This is also why you get the "access: No access entries loaded" error.

Good luck.
Steve.

So OTA EPG doesn't work without a special build? I been trying to get it to work on a pi2 with openelec for a couple of weeks. I had guide on my first try with EIT, I thought anyway, I know I didn't set up xml file. But most of the data was wrong, double triple entries on wrong channels maybe a couple were right. So I started over and have not been able to get it back.

Jim DiCarlo

Yes, you need to compile a special build to get OTA EPG data to work. It's not that difficult to do (Follow Steve Smith's post to me) and it was simple. I recommend doing the build on OSMC (Open Source Media Center), works super smooth and I get 2 full days of data on my Rpi on most channels in my area. Make sure you purchase the MPEG2 codec from RP to play the feeds (if you did not know that already)

So what is in the zipfile at https://github.com/laurimyllari/tvheadend/tree/atsc-epg. Is that the source for the EPG plugin, or full version of tvheadend with plugin. Read all the posts in this section and am confused at what looking at. Do I have to do it in a Linux distro with terminal or can I compile in osmc or openelec remotely. I'm guessing terminal or putty for windows?

Lee C

Okay, I followed what I understood to be Steve's instructions above. The commands/steps I followed:

From the OSMC Release Candidate, built via Windows, then set up networking, timezone on OSMC

Telnetted in as osmc/osmc and did:

sudo wget https://github.com/laurimyllari/tvheadend/archive/atsc-epg.zip sudo unzip atsc-epg.zip
sudo rm atsc-epg.zip
cd tvheadend-atsc-epg
sudo apt-get update
sudo -s apt-get install git build-essential pkg-config libssl-dev dvb-firmware-osmc dvb-tools libdvbv5-0 liburiparser-dev liburiparser1 libavahi-client-dev zlib1g-dev libavcodec-dev libavutil-dev libavformat-dev libswscale-dev
sudo ./configure
sudo make

sudo make install

With a couple of reboots in there.

I've tried tvheadend, sudo tvheadend, sudo tvheadend -c -d --firstrun...and in every case, when I try to access via the browser, I get an error 500 on the Pi screen, so I'm guessing I didn't get the web portion installed properly. Also, I have a successful version running without the OTA EPG with a WinTV-950Q, but I had to install some specific firmware/drivers to get it to work, and I can't tell - because I can't get into the browser - if I need to do that again.

The errors on the console indicate that it failed to open src/webui/static/extjs/[something]/[something else], but every time I look, the [something] is a file...not a directory.

I did a re-download of that file and an unzip - and those directories are not there on the new download, either.

Can somebody point me in the right direction?

Thanks!

Steve Smith

Brian: This is the full version of tvheadend with the atsc-epg plugin. Currently it has to be done this way as the plugin has not been merged with tvheadend yet. It is still an experimental plugin. I compiled it on Ubuntu Linux using a terminal. I have never compiled anything remotely or have used windows for over a decade so I can't help you there.

Lee: My advice to you is to see if tvheadend is running. Try running "top | grep tvheadend". The command "top" allows you to see the running processes, "|" is a pipe which pipes the output to what follows it which is "grep tvheadend", a filter to only show the tvheadend process if it is running. If there is no output then tvheadend is not running. The errors on the console might be a file permissions problem. I noticed that you ran "./configure" and "make" with a sudo prefix. That may cause the problem. Rebuild but only prefix "make install" with sudo. You said that you got an error 500 which means "Internal Server Error: The server failed to fulfil an apparently valid request. A generic error message, given when an unexpected condition was encountered and no more specific message is suitable.". This is most likely caused by an invalid url. If you ran the url "http://localhost:9981" and that does not work than maybe your system is not aware of localhost. Try "http://127.0.0.1:9981" and see if that works. If you are accessing that remotely you probably need to use your internet address, I don't have a clue. I would re-compile using "./configure", "make", and "make install" before anything else, it's your call. You can also post the output of "./configure" and "make" during the compile phase, and "tvheadend --firstrun" after it is compiled. You can pipe the terminal output to a file using "make > make.log 2>&1".

Good luck,
Steve

Jim DiCarlo

Steve, it's been running good with the OTA EPG data, just a few questions.

I had a hard time getting the custom build running as a service, do you have a working script that I can install that would work correctly?

Also, I really need to schedule tvheadend to grab data at certain times of the day, what is the best way to do this?

Thanks

Jim DiCarlo

Sounds like a bad compile, make sure that you are not getting any errors before compiling / installing because when done correctly, it works great

I am not sure of why the webui comes up blank or I would have tried to help. I have been successful installing this version on both OSMC and Xbian, I personally like Xbian better, but that is my preference.

Just a comment, I never used or configured this with silicondust HDhomerun option, so I cannot help anyone with that option.

Brian Hanfgarn

What i mean by blank is, when I type in ip to login. It acts like it's loading the icon shows up in the browser tab but none of the ui loads just white page, nothing. But the text below shows up in command line.

Jim DiCarlo do you remember exactly how you installed it? Do I have to install in a certain directory, is there any permissions I have to change?

P.S. tried to install again, and now I get connected to XBMC below the above error text, so guessing that from the other install, so it looks like the webui is the only thing broke.

2015-05-05 20:53:50.970 [ INFO] htsp: Got connection from 127.0.0.1

2015-05-05 20:53:51.019 [ INFO] htsp: 127.0.0.1: Welcomed client software: XBMC Media Center (HTSPv8)

Also browsing directories with WinSCP I don't see src/webui or /static/extjs/ as directories Does that mean they were never installed?

Jim DiCarlo

Not sure what is happening, seems to be a corrupt build. I see that you are doing this in windows, I DONT DO WINDOWS unless you put a gun to my head. Not sure if it matters but I am doing my build ssh to my my RPI2 while using Linux Mint 17.1.

One problem I had when I was compiling on Xbian and kept on getting errors so I used the Autobuild option which I believe I found in this link: https://tvheadend.org/d/2245-tutorial-installing-codecs-and-tvheadend-3-9-with-transcoding (not that you can run transcoding with the RPI2, so dont try the transcoding options even though it will allow you to do it)

Hope this can help you.

Steve Smith

Just a thought. Have you tried copying the files over? Try the command "sudo cp -Rpnv <path_to_extracted_zip_file>/branches/atsc-epg/vendor/ext-3.4.1/examples/ux/gridfilters /usr/local/share/tvheadend/src/webui/static/extjs/examples/ux" where cp means copy, R means recursive, n means do not overwrite existing files, v means show what is happening. The command "man copy" will pull up a manual on the copy command. If you look at the source code, you will notice that the "gridfilters" subdirectory is a link instead of a hard subdirectory. Wonder if your system is having trouble with links. If your installation isn't in "/usr/local" then it may be in "/usr". There are others like "/opt", etc... One more thing, if you also have a tvheadend package installed from your package manager, uninstall it as I have seen some screwy things happen when you install a compiled program when a package was already installed. If this fails, and yes it sucks, use a different OS or possible an OS that is a different version. It's just supposed to work. Hmmm, do you have java installed? I would check that if I were you. I would also check if it's working. If you notice the affected files are all javascript components. These might not have been installed if java was not detected. You said that the mainstream version of tvheadend works. If that is true, then it is not a java problem. Try copying the files first. There may be more files you need to copy too. I think it has to do with the subdirectories that weren't copied during installation are links and not hard. Not much of a linux installation if it can't handle links though. I have nothing more to offer.

P.S. Those files are in the download as well as the installation on my computer. Since your sha1sum was the same as mine, those files are on your download. If not, then the zip file was not extracted properly. Some extractors have options for them which will allow them to skip links. If your extractor was configured this way, then that would explain why you do not have the "gridfilters" subdirectory in your extracted file as it is a link. Now that I think about it that is the most logical explanation as you did not have to unzip the mainstream tvheadend version that worked since it was a git repository which does not need extraction. Clear enough? Try extracting it using a different program or study the man page of the program you were using.

Steve Smith

I believe I have found your problem. You say you have been using WinSCP to copy the files to your Rpi. I have found the following information at "http://winscp.net/forum/viewtopic.php?t=15092".

[Question]

How does WinSCP handle Synchronization of symbolic links [UNIX machines], especially when those links references or point to files outside of the root directory of the scp/ftp download?

[Reply with quote]

Well, that's rather complicate question. With SFTP protocol, with which the client (WinSCP) has good control over the remote files, symlinks to files are treated as the file itself, and SYMLINKS TO DIRECTORIES ARE IGNORED (no matter where they point to).

Brian, since your missing a directory called "gridfilters" which is a link also called symlink or symbolic link, the directory is getting thrown away. Since OSMC is a debian based Linux OS, it is symlink aware (as most every Linux OS is), however I know that Windows was not aware of symlinks in the past, I've read that they can handle them now. I suggest either copying the files over like I instructed previously or using a different program that is symlink aware. Why can't you download the file directly to the raspberry pi? That device has an internet connection port. It runs an OS. What you need to extract the file should be on there already. Just a thought.

P.S. The rest is up to you. Study your directory structure of the extracted zip file and the directory structure of the copied (by WinSCP) structure and find out where the difference is. It is NOT a problem with Lauri Myllaris' version of tvheadend. I am sure of that. Don't ask me about Windows programs, like I said previously I have not used Windows in over a decade. Google it! When you find the solution, I would appreciate it if you would post the solution to it, and clean up your previous posts so as to remove the clutter on this forum and make it easier for people to get the information they need. I do that every so often myself.

Brian Hanfgarn

I think my issue is with permissions. I installed on my other raspberry pi, pi2. And had the webui issue again. Typed sudo -s and then it worked. Doesn't that give administrative permissions? I'm a bit lost when it comes to permissions. Guess that's why Linux is a secure platform. So is home folder open to do whatever? What do you mean by .Hts is hidden, do I have to do something to see it? Does this install to the same folders as the main branch? Might be good to know while figuring out the autostart.

Jim DiCarlo

if you get it working again and you want it to auto launch at start up, just edit the rc.local file and add this line:

" sudo tvheadend -C & "

make sure this line is before the "exit" line

Works for me perfectly in OSMC and Xbian

Brian Hanfgarn

Thanks Jim, I kinda had it working it would autostart and run on it's own but I couldn't get it to run webui. Channels worked in Kodi cause I had already configured channels with tvheadend -- firstrun before autostart. What folder are you compiling on? What extraction tool are you using? I've started over and installed to /home with unzip but I got the webui crap again, will try 7zip again. And start doing it on my Pi2 B cause Pi1 B with 256mb takes way to long to compile. It's like 20 mins vs 45 mins to an hour.

Jim DiCarlo

Sorry, it's been months since I did this and cannot remember all the steps, I just followed Steve Smith's directions in this thread to get it working. The only error I got when I could not log into the webui was I did not do the "firstrun" option.

When I ssh into my box, there is a .hts directory as I log in and type ls -a

root@xbian ~ # cd .hts
root@xbian ~/.hts # ls
tvheadend
root@xbian ~/.hts # cd tvheadend
root@xbian ~/.hts/tvheadend # ls
accesscontrol bouquet channel config dvr epgdb.v2 epggrab input profile

Brian Hanfgarn

Thanks again looks like everything works now. Autostart and all. I guess extracting with 7zip really is what fixed my issue, using unzip doesn't work. Also I installed it to /home folder this time.

One more question. Trying to get it to work with WinTv 950q tuner now. It does show up in device list but doesn't detect channels. Should I try to install firmware? I know Sam likes to bake the firmware into his software like RaspBMC and OSMC.

Jim DiCarlo

I never used the 950q tuner, but at one point was using the Happauge HVR-850 tuner, it was utter garbage (it would not reinitialize after reboot and I would have to manually remove it from the USB port and reattach it for it to be seen), I changed to a very cheap $24 Kworld tuner UB435-Q, and it works flawlessly under OSMC and Xbian and never fails to show up after reboot without user effort, Highly recommended!
