Until now this fails showing the message "../src/pjmedia/codec.c:53: pjmedia_codec_param_clone: Assertion `pool && src' failed." This happens in pjmedia_codec_param_clone(). As I use the memory pool prior to this step without any problems, the passed pjmedia_codec_param struct must be the problem. I noticed that there is the same problem, when I start the sample application streamutil. My first guess was to initialize the pjmedia_codec_param with default values which is owned by the pjmedia_stream_info struct which is passed to pjmedia_stream_create(). For this I used pjmedia_codec_mgr_set_default_param(). But this seems not to work. Did anyone came across this issue? If yes how did you solved it? regards _______________________________________________ Visit our blog: http://blog.pjsip.org[http://blog.pjsip.org/] pjsip mailing list pjsip at lists.pjsip.org http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org[http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org] ? ?
