Rajil,

The error you are getting has nothing to do with ALSA, so don't bother
with that.

The message you are getting is displayed when OpenH323 cannot find a
required function in the libavcodec.so file needed for H.263. This file
is loaded at run-time due to licensing issues, and it obviously exists
on your system but just as obviously, it is the wrong file.

You don't say whether you are enabling the non-compliant H.263 (the
default configuration) or the compliant H.263 (which requires the
--enable-rfc2190avcodec dir option). Either way, you will need a
modified (and different) libavcodec.so file.

My guess is that are just running "./configure", and your program is
trying to use the unmodified FFMpeg libavcodec.so file, rather than
using the modified one that is needed. That will cause the error you are
getting.

If you don't care about H.263, then you need to stop OpenH323 from
finding and trying to load the incorrect libavcodec.so file. To do this,
edit the openh323u.mak file and change "#define H323_AVCODEC 1" to
"#undef H323_AVCODEC"

If you do want H.263, then read http://www.voxgratia.org/docs/h263_codec.html
about how to use the --enable-rfc2190avcodec option to configure.
