Tvheadend

Hi,

I try to compile the latest GItHub version on my ARM (Cubietruck, Jessie 8.5, ARMBIAN 5.2, with all the latest software) system. Unfortunately it is still unsuccessfull, since I am a newbie to compiling software. Enclosed you'll find the log of ./configure --arch=ARM (configure.log) and make (make.log).

Unfortuntaely I am not in a position to evaluate the errors, and what went wrong.
I really appreciate the support of the community and appreciate any valuable hints an comments for debugging and compiling tvheadend successfully!

Many, many Thanks in advance!

regards, Ireng

The errors are related to ffmpeg - you can still build tvheadend without ffmpeg support, meaning no transcoding, arm devices aren't usually fast enough to do it via CPU anyway.

Also, why are you using configure/make. The autobuild.sh will create a nice deb package that you can install using dpkg.

 AUTOBUILD_CONFIGURE_EXTRA=--disable-bintray_cache\ --disable-hdhomerun_static\ --disable-ffmpeg_static\ --disable-dvbscan ./Autobuild.sh

Hi HTH,

thanks for your advice!
After installing ffmpeg I receeived the following output from Autobuild.sh:

Installing ffmpeg yourself won't actually change anything as the makefile builds it's own version to be included with the Tvheadend binary. Until the problem has been resolved you won't be able to build Tvheadend with ffmpeg support on arm.

For now, you're going to have to disable building tvheadend with ffmpeg support.

Thank you for your answer and advice!

Could you please give me detailed instructions on how to build tvheadend on ARM without ffmpeg support?

Many thanks in Advance!

Use the command in my first response You may want to remove "\ --disable-hdhomerun_static" if you need hdhomerun support. run ./configure --help for more options, you then add them to the variable (escaping the space).

Thank you very much for your help and support!

At least i got tvheadend up and running. However, after startup I received only a "blank" page !!

What happened to me again??

Regards, Ireng

PS: is there any timeframe available unteil the ffmpeg problem for ARM might be fixed ??

Regards again, Ireng

use bundle option in compilation

@saen acro: Thanks for your advice!

Where to use the bundle option ?

Could you give me the detailed command ??

./configure --help does not show any - bundle - option!!

Sorry, for the question, i am very new to compiling software!

It's --enable-bundle. You probably don't need to rebuild with the bundle option as you're more than likely just running tvheadend from the wrong directory.

You need to run it from the build.linux directory while in the main source folder (basically just don't cd to build.linux).

for example, the tvheadend source dir is /home/user/tvheadend.

so..

cd /home/user/tvheadend;
./build.linux/tvheadend --args

Sorry, for the question, i am very new to compilinmg software!

Regards, Ireng

Ok, thanks for your advice!

The opening page remains still blank!

Regards, Ireng

PS. I started tvheadend with the following command:
./build.linux/tvheadend -f -C -u user

--enable-bundle

this will build integrated executable file (larger of course)

./configure --enable-bundle

Hi @saen acro:

Many, many thanks for your help an guidance!

I used ./configure --enable-bundle --disable-ffmpeg_static and make to install successfully the binary!

After launching tvheadend i received the nice firstrun wizard, to be able to configure tvheadend easily!
Compared to the configuration of 4.0.9 it is a great help. After finishing, I received a message for input of

user / passowrd. I enetered the admin user password / user name password as entered througout the firstrun wizard, but neither combinaqtion worked ! However, i cannnot access the WebIf at all!

What a pity, after such a successful compilation and setup !

Regards, Ireng

Ok, All of a sudden the webui accepted the admin credentials!

Regards, Ireng

Disable "Use HTTP digest authentication:" in Config -> General -> Base if you continue to experience that bug.

Mark Hunting: thank you for your advice!

Sofar everything works fine on my cubietruck accessing my SATIP server !

Many, many thanks for your supoort and even more for the great, continuing work.

Currently I installed minidlna for accessing easily my recordings, however i wait until tvheadend provides the promised integrated DLNA server!

Best regards, Ireng

I do have an additional smal question about the configuration of PVR profiles.

For TV recordings I use the default profile, so good, so far.
For radio only recordings I defined an audio only profile.

However, If I select some radio - only programs I can select the audio only profile after adding it to the list of recordings. Refreshing the page results in changing the audio - only profile into the standard profile!

What happened and how to pin the audio - only profile the selected radio recording!

Again, many thanks for your support & help!

Regards, Ireng

PS. OK, I forgot to explicite SAVE the configuration!

I noticed, that tvheadend accesses the SATIP server on both tuners continuiously, even NO recording is scheduled!

How to avoid or limit this behaviour ??

Reagrds, Ireng

Reagrds, Ireng

That is the default behaviour, it's more than likely grabbing EPG, and/or you've enabled "Idle scan muxes" for the network. Turn that off in the networks tab - [Edit] your network) & disable EPG grab "Over-the-air EPG" for one of the tuners .

HTH

Hi, thanks for your guidance!

i found the Idle scan option inside each of the 2 tuners of the SATIP server and disabled them.

The Mx idle search inside the network tab was NOT selected!

Anyhow, thanks for your advice!

I am still climbing the learning curve!
