Description

I'm trying to compile the latest git checkout of tvheadend on a debian jessie release...

I'm getting the following compile errors:

History

#1

Updated by Sascha Schmidt about 11 years ago

Seems to be in issue because of a new libavcodec version:

Took this from http://devel.mplayer2.org/ticket/144:
[...] Various old APIs were dropped from Libav git (and these changes were merged to FFmpeg too); the opt.h change is only a small part. Unfortunately using the new APIs requires either dropping compatibility for anything BUT the latest git head (including the recent Libav release, as it had some problems in these APIs) or adding extra workarounds. [...]

#2

Updated by Steffen Vogel about 11 years ago

I fixed it by simply replacing the old API functions with the new ones.
But Im not sure if it builds on older distros.. Only tested under Debian jessie.

#3

Updated by Sascha Schmidt about 11 years ago

The old error is gone, but is replaced by a new one...

Updated by Sascha Schmidt about 11 years ago

Is there any active development or is this project going to die?

#5

Updated by Sascha Schmidt about 11 years ago

Working through the libav manual I've changed some functions and defines:

Install:

git clone https://github.com/tvheadend/tvheadend.git


patch -s -p0 <tvheadend-libav-new-api.patch

The files within the directory "tvheadend" are now going to be patched. Afterwards you can compile tvheadend with the new libav (for example debian jessie).

Attention++
libav dropped the compatibility support. It will NOT be possible anymore to compile tvheadend with old libav versions.
