Tvheadend

I have the same problem.
I'm on archlinux and my "avcodec.h" has no member "encode". But, I have the function declaration "encode2"....
pacman -Qi ffmpeg:

The transcoding stuff uses libav, which is particularly problematic from an API point of view. I've not had a chance to check the code since John pushed, to make sure version checks are right or that at the very least the code can be disabled at build time.

For now just go back to before John pushed, master will be very quiet for a while as I'm busy (when time permits) working on the DVB rewrite on another branch.

I am on arch as well. I have tryed removing the test for the encoding function keeping encoding2 only on that line and then it compiles fine. However I am still unable to make it transcode by trying to stream via http e.g.
http://localhost:9981/stream/channelid/54?ticket=&lt;valid-ticket-here&gt;&mux=PASS&transcode=1&acodec=AAC&vcodec=H264
Most likelly this is my error and I am unable to figure it out.

According to Peter Vágner I changed also git source:

Ffmpeg AVCodec does not have function "encode" any more it's called "encode2" now (http://ffmpeg.org/doxygen/trunk/structAVCodec.html
)

So my quick and dirty change is dropping function encode from souce.

diff Naur ../tvheadend.orig/src/plumbing/transcoding.c src/plumbing/transcoding.c

while ((p = av_codec_next(p))) {

- if (!p->encode && !p->encode2)
+ if (!p->encode2)
continue;

if (!WORKING_ENCODER(p->id))

Beg your pardon - I'm not familliar wit git to get patch.

My system is debian unstable:
libavcodec-dev:amd64 8:1.2.1-dmo2
libavcodec53:amd64 7:0.10.3-dmo1
libavcodec54:amd64 8:1.2.1-dmo2

Perhaps that might help ....

A commit has been made that tries to address this issue, please give it a try and report back if it works or not.

Compiled fine on Arch Linux x86-64, ffmpeg 1.2.1-1.
Tested also 2 dvb-t streams, seems to work fine.

Works great also on Arch Linux armv5.

You may want to add ffmpeg to the dependencies list on the wiki.

Hi John,

Looks like mine is hitting a problem with current git master:

Andy, what distribution are you using?

Sorry, wasn't watching the thread so didn't notice you'd replied!
It's on a debian-32 bit system I'm on. I'll try and catch you on irc to diagnose/debug.

it compile just fine for me.

I installed http://cdimage.debian.org/debian-cd/7.1.0/i386/iso-cd/debian-7.1.0-i386-netinst.iso in Virtualbox

apt-get install pkg-config libssl-dev libavcodec-dev libavutil-dev libavformat-dev libswscale-dev

you are using libswscale-2.2.100, while the debian version I installed uses libswscale-2.1.0.

I also tested with archbang, who uses libswscale-2.2.100 (but with newer version of the other libav* libs), that also works.
It seems as if you've managed to install a newer version of libswscale ontop of an older version of libav*

in any case, you can still build tvheadend by disabling libav (./configure --disable-libav)
