Hello Marco,
Thank you for the example code. I made the changes and can now record in RAW
and MP3 format. But when I pass a pipe to the pjsua --rec-file argument the
application still halts. Probably I still need to change the code that opens
the file to open it in streaming mode instead of random access mode. Can you
give me a pointer where this is done?
Best regards,
Jan.
