Package: libx265-59
Version: 1.7-2
Tags: patch
Dear Maintainer,
The 8-bit variant of libx265-59 can dlopen the 10-bit variant,
so that it can be used by programs linked against the 8-bit library.
ffmpeg 2.7 uses this functionality, which works fine in Debian.
However, it doesn't work in Ubuntu, which causes ffmpeg's autopkgtest
to fail, thus preventing it's migration from wily-proposed to wily.
The problem is the following x265 warning on stderr:
$ ffmpeg -version
x265 [warning]: /usr/lib/x86_64-linux-gnu/x265-10bit/libx265.so.59 does not
support requested bitDepth 10
ffmpeg version 2.7-1 Copyright (c) 2000-2015 the FFmpeg developers
built with gcc 4.9.2 (Ubuntu 4.9.2-20ubuntu1)
[...]
The reason for this problem is that Ubuntu defaults to using
-Bsymbolic-functions, which causes the max_bit_depth symbol to always
refer to the one from the linked library, even in the api structure
from the dlopened library.
(Weird, I know. I suspected -Bsymbolic-functions, because it already
caused ffmpeg to FTBFS in Ubuntu.)
The solution is thus to filter out -Bsymbolic-functions from LDFLAGS,
as is done in attached patch. I tested it and it fixes this problem.
Best regards,
Andreas
