...................
I use ffmpeg from git (version # N-61767-gc08e523) with
libx264 from git
./configure --enable-shared --enable-libx264 --enable-gpl
--disable-stripping && make && make install
Don't forget disable stripping. I also work with some
limitation with
libav. (dyna, slopen, dlsym).
Dyna.cxx from opal dlopens libavcodec.so and check functions
using
dlsym.
If libavcodec is stripped, dlsym fails (and of course dyna).
For avcodec_init, last versions of opal didn't use this call
anymore and
in opal_10 this call is deprecated - see
opal/plugins/video/common/ffmpeg/libavcodec/avcodec.h
Thanks Thierry. This had me looking in the right direction. It
turns
out to be --enable-shared in ffmpeg that is the problem. I
still don't
get video for h.263 but that avcodec_init error is gone.
Here's what I see now:

Pool:0x7f1008084700 Opal
Error creating transcoder instance from H.263 to YUV420P
I'll keep plugging away at this.

For plugins : have a look at opal/plugins/video/
H.261 : internal plugin
H.263/H.263-1998 : ffmpeg
H.264 : system if using libx264
common : tools for ffmpeg use, especially dyna for dynamic
loader

Check if configure generates Makefile and
make builds all plugins.
I had to add -fpermissive flag in Makefile.in, some
CODEC_FLAG_Hxx in
h263xx.cxx, and change CodecID by AVCodecID
Yeah, I have a patch for that AVCodecID problem.
Here's a full message though. It seems to be looking in the wrong
place
for them:

Looks like I need to build this in a chroot, since my system is
multilib.
That may be messing with it.
