libav on debian squeeze

Dolphs Lundgren

Hi - trying to get libav going on debian squeeze.

Added squeeze-backports to sources.list and installed following packages: " apt-get install build-essential git pkg-config libssl-dev bzip2 wget libavahi-client-dev zlib1g-dev libcurl4-gnutls-dev libavcodec-dev libswscale-dev libavfilter-dev libavformat-dev libavcodec-extra-53 ", however as you can see below libav remains on " no ".

What package / step is missing here as I kinda follwed the tvheadend wiki at: https://tvheadend.org/projects/tvheadend/wiki/Building

Hi Dolphs,

Although i think libav is enabled per default, did you try:

./configure --enable-libav

( you can use configure --help to see other options as well).

If this also doesnt work, then I would guess either libav cant be found, or it is the wrong version.

Checked on my system, I got a different version of libav-codec , i.e. 54.59.100

But it seems 53 is also ok (needed > 52.96), so it would seem that somehow libav cant be found.

However, I do not use Debian, so I cant check the specific version that is available on Debian.

thanks for response... Yet I took a VM image and started from scratch with debian squeeze:
It seems in squeeze there is no libavcodec53-dev so need to find 1-1 what libraries are needed as squeeze-backports do support 53 ( limited ).

Gave it an unfortunate try with:

:~# apt-get install libavcodec-dev libavcodec53

Do you want to continue [Y/n]? Y

so this will result in the expected libavcodec that does not meet the requirement :

You might try building libav from source:

looks interesting - however currently focussing on ffmpeg: https://trac.ffmpeg.org/wiki/UbuntuCompilationGuide ... least effort to get this libavcodec sorted

tried following still no joy:

./configure --enable-shared --disable-static

make && make install

Maybe the version of libav you installed from source is too new ( since it is the most recent version with commits just 18 hours ago).

Looking at github there is also a version called release/0.5 , the last commit for that one is from half a year ago.

Maybe try to install that branch of libav using 'git checkout release/0.5' ?

( running out of ideas, but installing this older version might help).

Dolphs Lundgren

yes we are getting close with release/0.7 but just not yet:

<snip snip>
checking for pkg libavcodec <=55.0.0 ... ok
checking for pkg libavcodec >=52.96.0 ... ok
checking for pkg libavutil >=50.43.0 ... ok
checking for pkg libavformat <=55.0.0 ... ok
checking for pkg libavformat >=53.10.0 ... fail
<snip snip>

Dolphs Lundgren

release/0.8 works!

thanks for assitance, another hurdle taken!

Guess "kqueue" is not relevant on debian as it is for BSD flavours and Max OS X, so I will ignore it just like these two: "bundle" and "dvbcsa".

thanks again!

Alex .

Good to know that it works .

( Good you checked all available version on github :-) )
