TVHGuide for Android

Thomas Novin · 2011-08-08T17:48:19+00:00

Anyone tried TVHGuide with success? All I get is a channel listing. I have tried it on my HTC Sensation (Android 2.3.3). http://sb1066.homelinux.com/tvhgui...

That video streams could not be played is related to ICS.

Tvhguide is segfaulting in surface_open call, cause there is a new way of initializing the surface.

I'm playing to create a patch...

Martin Mrvka

it needs more testing, but it's working:

https://github.com/mmrvka/TVHGuide/commit/5ac6b9506ca9a441fb0905087d696c89957f4eb5

(Although there is still an null pointer exception, no max resolution is selected)

OK, most likely, I'm messing it up with my own building... :) But it still does not work for me.

I simply downloaded todays snapshot from your link, built and tried to run, but it still does not work.
In the emulator it has problem at startPlayback()->stopPlayback()->System.loadLibrary("tvhplayer")

I think the first time i debugged the program I got a different exception, but now I repeatedly just get Unsatisfied LinkError..

Since I'm a newbie on android development, I am sure I have missed out on something...

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 (native development kit)" 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).

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:

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).

Joshua Welch

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...

John Törnblom

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?

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 .

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).
