Hi all.


I'm working to compile opal-3.10.7 on my Fedora 17 64bit.
After
*./configure
--disable-silk*, *make* fails with

Error 1

Peter, do you know what is the problem? I tested it with
libav...


With the option *--disable-libavcodec, *make completes
its

work but

ffmpeg codecs are not available.

If i remember properly this issue pops up with the old
release of
Ekiga
too and it was linked to ffmpeg.


Please, i wish understand if this is a issue related to Ekiga
or to

ffmpeg
in Fedora.


Antonio, it could be a mismatch between ffmpeg version and opal.

Do you
use ffmpeg or libav? What version exactly
(/usr/include/libavcodec/***

*version.h)?

Is it the version from Fedora or another one?



Hi Eugen.
I use ffmpeg (v. 0.10..4-2) from Fedora repository.


Indeed, you use version ffmpeg 0.10.4. Could you send the
plugins/config.log file from opal directory?

Also, what gives the command:
grep PICT opal-directory/plugins/plugin-******config.h



$ grep PICT plugin-config.h

/* #undef AV_PICTURE_TYPE_NONE */


Could you confirm that line 305 from /usr/include/ffmpeg/libavutil/**
**avutil.h

is:
305 AV_PICTURE_TYPE_NONE = 0, ///< Undefined
?


I confirm.



If yes, then please do:
- in opal/plugins/video/common, rename ffmpeg directory to ffmpeg2 (so
that it is not found)
- rebuild opal (./configure and make)



See attached.


The problem is the following. Opal in config.log says:
checking if libavutil has AV_PICTURE_TYPE_NONE... no
checking if libavutil has AVPictureType... no

On the other hand, your ffmpeg from Fedora has in avutil.h:
304 enum AVPictureType {

305 AV_PICTURE_TYPE_NONE = 0, ///< Undefined
[...]

So opal configure does not find AV_PICTURE_TYPE_NONE, hence it
defines it,
but afterwards there is collision since it is defined in avutil.h.

I found the problem. configure check for AV_PICTURE_TYPE_NONE in
avcodec.h... Some versions of ffmpeg had it in avcodec.h, and your
version of ffmpeg has it in avutil.h...

However, I do not understand why there was no error on Fedora official
builds.

Let me think how to fix this.

In the meantime, could you do the following and tell me if the compilation works?

In plugin/plugin-config.h, comment out the line containing AV_PICTURE_TYPE_NONE, and do make again.
