Please use PortAudio, and if you prefer using DirectSound backend, you can set PJMEDIA_PREFER_DIRECT_SOUND to 1 in your config_site.h Did you set PJMEDIA_RESAMPLE_IMP to PJMEDIA_RESAMPLE_NONE? That seems to be the only reason for PJ_EINVALIDOP error. cheers, -benny > When I run pjsua_vc8d with this option > --play-file file.wav > > I obtain this message : > 08:30:54.713 wav_player.c File player 'file.wav' created: > samp.rate=22050, ch=1, bufsize=4KB, filesize=5977KB > 08:30:54.713 pjsua_media.c Unable to add file to conference bridge: > Invalid operation (PJ_EINVALIDOP) [status=70013] > 08:30:54.729 pjsua_core.c Shutting down... > > > If I didn't define play-file option, and I make a new call, I obtain the > following message : > 08:54:16.432 pjsua_call.c Unable to create media session: Invalid > operation (PJ_EINVALIDOP) [status=70013] > > before I can read in the log file : > 08:54:04.338 dsound.c DirectSound initialized, found 5 devices: > 08:54:04.338 dsound.c dev_id 0: Pilote de capture audio > principal (in=2, out=2) > 08:54:04.338 dsound.c dev_id 1: C-Media Rear Panel Audio (in=0, > out=2) > 08:54:04.338 dsound.c dev_id 2: Lecture sur modem n? 0 (?mul?) > (in=0, out=2) > 08:54:04.338 dsound.c dev_id 3: C-Media Rear Panel Audio (in=2, > out=0) > 08:54:04.338 dsound.c dev_id 4: Enreg. sur modem n? 0 (?mul?) > (in=2, out=0) > 08:54:04.338 pjlib select() I/O Queue created (00CBCC0C) > 08:54:04.338 conference.c Creating conference bridge with 32 ports > > I obtained the same messages with portaudio. > > Do you have an idea to resolve my problem > > Best regards > > Samuel
