Tvheadend

For playback, TVHGuide is using a C library, accessed from java through JNI. This library needs to be compiled too, otherwise it's causing the exception you've posted.

Doing this using linux is easy:

1) Download the Android NDK to your home folder and extract it
2) Change to your project root (e.g. /home/<yourname>/workspace/TVHGuide)
3) Run the ndk-build from the NDK (just run: /home/<yourname>/android-ndk-r7/ndk-build)

After the build process created and installed the libtvhplayer.so (done automatically), go to you IDE and refresh your project (just to be sure, since you've done the steps above outside the IDE).

HTH

Thank you for the detailed help! It worked flawlessly when I followed your steps!

I'll do some more testing now

Will be possible run TVHGuide on Android 2.2 ?

I have a Motorola Droid X with Android version 2.3.3, but when I try and watch tv via this app, it force closes.

Can someone tell me what I can do to find out why, or if my TVheadend is the wrong version:

This is the version of TVHeadend I have:

If you've compiled it by yourself, it's very likely that you've forgot to build the libtvhplayer.so lib using the NDK (see three posts above).

I'm sorry I do not mean to be stupid, but I am really struggling to get this working.
I did not compile anything from source. I have only installed with the link.

Do I need to install android sdk? I still don't know where to put the library when I have generated it either.

Well, if you've installed directly from http://sb1066.homelinux.com/tvhguide/ and it's not working, then you should put an issue there: https://github.com/john-tornblom/TVHGuide/issues/new.

Setting up a working android dev environment is beyond this topic and I doubt that it will not force close if you're compiling by yourself.

is the apk updated for ics or is ther a posibility to download a compiled version som where i like to test it .

for anyone else.

Thanks!

Hi all,

I have managed to install the right version of the transcoding branch using the info of this forum (together with some trial-and-error) on my Gentoo system.
(there were some trouble installing the right version of the transcoding branch in combination with libav/gffmpeg; some versions did not work with my version of Libav as mentioned in this forum by other people)

I can now watch using the following in either a browser or in VLC:
http://192.168.0.30:9981/stream/channelid/34

Now my qyestion is : Is there a way to make tvheadend stream a lower bandwidth version, as the Android App seems to suggest, from a browser or from VLC?

Thanks for any info,

Alex.

Ps If this is a trivial question: sorry for asking, I tried to look into the documentation but couldnt anything about this...

Sorry for being idle, I've been so busy lately. Development is going to continue to be slow for a while. If there are issues, post them on github and I'll attend them at some point

My priority is getting webm going in tvheadend and supporting android 4. Android 4 also got some new media support that needs some investigation (opensl es, openmax al).

Thanks for the support!

Im having troubles with lagg/stutter and what not on vlc on the PC with transcode branch

Get these in the log, Anyone know that recognize what i did wrong?

(works good without transcode branch)

having som trubel whit the build when doing the make i get this ?

I just had this conversation with the developer, you need to remove -Werror from line 27 of Makefile, it is because you are using a higher version of gcc than the developer.

I did that and it compiled fine.

GL!

thanks

did get a bit longer .

do i miss som library ? or shoud i configure whitout avahi ?

I couldn't get that repo to work either,

 git clone -b transcode git://github.com/john-tornblom/tvheadend.git

seems to but I do not get the transcoding working right from that.

Doesn't it work at all, or only not from the android app ?
( in my case, watching live tv with the transcoding branch now works, but I have the wrong android version since it appears you need 2.3 . Trying with the android app from android 2.2 make tvheadend crash just as in your case).

Well yea I cannot get the app to work, but I was told that I should be able to go to http://192.168.1.192:9981/stream/channel/12%20WJTC and see a channel, but it just gets me a 404.

I am on 2.3.3, so I know I'm on the right version on android, and I checked with my phone (DroidX running Liberty Rom) and my wife's phone (Moto Razr, stock everything). Force close on both as soon as I hit play. I tried to check logs (with a log viewer) but frankly I'm not sure what to look for.

What do the logs on tvheadend itself say? There should be messages in the lower window the moment you try to connect.
So basically: go to tvheadend on a PC, and then watch for messages while trying out on your android phone. Also, try the same link from a PC first while watching for errors, and make sure that works.
(Or does it crash before any messages appear ?)

It said welcome client software and the next line is disconnected. That is even with debug on.

f....k cant make it work .

what distro (debian/ubuntu ....) are you using im going to make a new install and woundering whitch is best for tvheadend transkoding branch .

im no need for grafics inter face ssh is fine ..

when you finely solve the problem whith tv cards and firmware,you have to do it all ower again but you learn and that is the funny part..

Does it say that also when watching from a browser on a computer ?
Or only from the app. (I have a similar problem with the app: running it on adroid 2.2 makes tvheadend/transcodebranch crash).

I'll post my setup down here, but I did not check the transcoding branche completely so i cant confirm yet that this setup should work:
I can install it and watch tv from VLC or a browser, just as in the normal tvheadend, but I do not have the right android to check the app itself... I would like to watch lower-resolution streams from VLC , not nececeraly from a smartphone app, but don't know/manage to do that (jet). Also, using the app on android 2.2 makes tvheadend crash (similar to what is reported here).

My setup is ( have to check for more details) :
- Gentoo 3.1.2
- HDHomerun dual dvb-c tuner with dvbhdhomerun kernelmodule
- a single dibcom/pinnacle dvb-t tuner
- Smargo Phoenix smartcardreader I use for dvb-C

switching disk and installing gentoo to se if i can make it work ..

thx ...

Ok, maybe one warning: Depending on your experiences with Linux, Gentoo might be a bit harder to install (but you will learn a lot ! :-) ), since you get to do all steps by yourself.
Also, all packages have to be compiled on the system.

So, all in all, this might be rather time-consuming if you are used to ubuntu....
