Hi, The pjsua/2 libraries have nice recorder management for file recorders but not for memory recorders. To use memory recorder I need to use low level API in pjmedia with efforts to handle pool and port creation / deletion. I made the attached patch which manages memory recorders in the same way of file recorders in pjsua/2. I think it makes it easier for people to use the memory recorder. Could this patch be merged into pjsua/2 library? Thanks, -Jiulong
