fails to lauch and to build because of undefined symbol

[mickabouille]

After an upgrade of dependencies, aegisub began to fail to start with the following message :
aegisub: relocation error: /usr/lib/libffms2.so.2: symbol ff_codec_bmp_tags, version LIBAVFORMAT_53 not defined in file libavformat.so.53 with link time reference

I tried to recompile the 2.1.9 branch, but it fails (logically)
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libffms2.so: undefined reference to `ff_codec_bmp_tags@LIBAVFORMAT_53'
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libffms2.so: undefined reference to `ff_mkv_codec_tags@LIBAVFORMAT_53'

Note: I'm on debian, the aegisub package comes from debian-multimedia.

It looks like the ffms2 library is built against a different version of ffmpeg or libav than is installed. I suggest you contact the package maintainer of the package that supplies libffms2, it isn't us.

This has been (sort of) fixed in ffms2 for a while now. Bug whoever maintains the package to update it.

Hello, I'm the reporter above.
I forgot to add my email adress so I wasn't notified of your comments, and now I can't get the password I've forgotten.

The libffms2 version seems new enough (it's the latest on  http://code.google.com/p/ffmpegsource/)

Can't there be something else ?

ffms2 2.16 doesn't support recent versions of libav/ffmpeg. 2.17, which does, should be out soon.

OK, DMO maintainer packaged a new version of ffmpeg that fixed this issue.
Thanks.

2.17 was released a while ago.
