Dear List,
I am compiling a stripped-down, static versions of the libraries, i.e. :
libavcodec.a libavformat.a libavutil.a libswscale.a libavfilter.a
libswresample.a
and I'm "baking them in" into a custom shared-library.
All external libraries are disabled, and configure script tells me that:
---------------------
...
Enabled programs:
ffmpeg ffprobe ffserver
External libraries:
Enabled decoders:
h263 h264 vc1
Enabled encoders:
rawvideo
Enabled hwaccels:
Enabled parsers:
...
--------------------------
i.e., no external libraries, no hw accelerators, etc.
I link with
/usr/bin/c++ -fPIC -g -shared -Wl,-soname,libValkka.so.0 -o
lib/libValkka.so.0.1.0 CMakeFiles/Valkka.dir/src/avthread.cpp.o

There's no freaking way to get rid of these vaapi-related symbols..! I
used to be able to do this with an older (1 year+) version of the code,
but now I'm getting way too much gray hair. I'm trying to do this with
the git branch
origin/release/3.0
It seems they come about in the following way:
----
grep -nr "vaUnmap"
libavcodec/vaapi.c:79: vaUnmapBuffer(vactx->display,
vactx->pic_param_buf_id);
libavcodec/vaapi.c:83: vaUnmapBuffer(vactx->display,
vactx->iq_matrix_buf_id);
libavcodec/vaapi.c:88: vaUnmapBuffer(vactx->display,
vactx->bitplane_buf_id);
Binary file libavcodec/vaapi.o matches
Binary file libavcodec/libavcodec.so.57 matches
Binary file libavcodec/libavcodec.a matches
-----
My own code is in cpp and in my header files I do:
------
extern "C" {
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
#include <libavutil/log.h>
#include <libswscale/swscale.h>
}
------
Growing desperate. Help appreciated!
Regards,
Sampsa
