@marc - ah, I wondered what would break - I've always used mkv, but I'm playing with moving away from that because of some sound issues I've been getting with mkv containers. So I might survive the loss of that container, but it's not ideal...

Yes, I'm sure it's perfectly possible to build against a different ffmpeg version, so long as it's a static build and includes all library calls it needs (because it can't depend on your local ffmpeg version since the shared libraries won't include the right functions). I'll maybe look later, although I'll warn now that I got horribly knotted up trying to build comskip until we had some idiot-proof instructions... but those same instructions should apply, albeit with a bit of tweaking of the Makefile or command-line options, perhaps.

The other option is to upgrade ffmpeg system-wide, which gets things compiling as you'd expect, but I don't know if that then breaks anything...

I don't know what this really leaves out, I think it's some new muxing code.

@schumi2004 - you don't need to do anything with tvheadend, comskip is standalone with no dependencies between them. You could run them on separate boxes if you wished...

I understand it's a standalone instance but can it be run on a Synology NAS?

If the NAS is running Linux and you can compile it, it should work fine. The program even nice's itself so even though it will consume as much CPU as possible, other programs will have priority.

Okay, I seem to have successfully built tvheadend against the ffmpeg I compiled as part of comskip - I haven't tested it yet, but it's linked okay and created the executable in ~/tvheadend/buid.linux/tvheadend. So I'll post this here in case someone gets a chance to test before I do (it's bed o'clock here).

It's as simple as changing to the tvheadend directory (~/tvheadend, most likely, if you've done a git clone from your home directory) and configuring the build with the following:

Code:
cd ~/tvheadend

PKG_CONFIG_PATH=/var/tmp/ComSkipWork/ffmpeg-1.0.1-install/lib/pkgconfig ./configure

Then make, and it sailed through without a hiccough for me. Note that you'll need to have installed and built ffmpeg as instructed in the first post, though:

Code:
cd /var/tmp

mkdir ComSkipWork

wget http://ffmpeg.org/releases/ffmpeg-1.0.1.tar.bz2

tar xf ffmpeg-1.0.1.tar.bz2

cd ffmpeg-1.0.1

./configure --prefix=/var/tmp/ComSkipWork/ffmpeg-1.0.1-install

make -j8

make install

You can vary this to your installation if required, i.e. build it alongside tvheadend if you're not using comskip.

Extend the technique specified for an external static ffmpeg....
1. download the latest argtable2
2. extract it into it's own subdirectory
3. ./configure --prefix=/var/tmp/ComSkipWork/argtable2-install
4. make -j8

Then to build comskip add /var/tmp/ComSkipWork/argtable2-install to the PKG_CONFIG_PATH (man pkg-config).

I'll add that to post # 1.

Thanks for your suggestion.
I recompiled tvheadend succesfully!
There is a difference for Media container in tvheadend configuration now (more options).

First I was able to choose "Matroska" or "Same as source (pass through)", which created .ts files.

Since I re-compiled it with the options you suggested, I got 2 extra options in Media container now:
"MPEG-TS" and "MPEG-PS (DVD)".

Thanks!

I think this is where it goes wrong:
checking whether the C compiler works... no
configure: error: in `/tmp/comskip-build/argtable2-13':
configure: error: C compiler cannot create executables

This may be because your gcc does not accept the given flags. You could try whether setting FLAGS="" would fix it.
Also, you may get the same message if you have not installed libc6-dev, if I remember correctly.

I think it's an issue with my GCC (checking whether the C compiler works... no), did FLAGS="" since libc6-dev was already installed but same error only later.
Going to check what is causing this.

Thanks for helping anyway Wink

I just put up a newer Cross toolchain build script. There are very few system specific things in the script, so it should run pretty much on any Linux system.

This version has been updated and should download all external dependencies.

Looks pretty good. I would suggest using /var/tmp rather than /tmp. I'ts common for /tmp to be a ram based filesystem on current Linux systems whereas /var/tmp should always be physical media (meaning you should be able to count on /var/tmp having enough space).
