Hi, I am coding a small sip client prototype using the python bindings. I am able to make and answer calls without a problem. However, when trying to create a player for a wave soundfile I get the following error: pjsua.Error: Object: Lib, operation=create_player(), error=Unsupported WAVE file format (PJMEDIA_EWAVEUNSUPP) I have tracked that error down to a disallowed file format: 11,025 Hz 8 bit PCM There is no documentation on which are the allowed formats. Tried different formats using the sample tool called playfile, and I have trouble even with 16 bit PCM files: 17:27:09.163 pa_dev.c PA message: Expression 'ioctl( devHandle, SNDCTL_DSP_CHANNELS, &temp )' failed in 'src/../../../portaudio/src/hostapi/oss/pa_unix_oss.c', line: 405 17:27:09.203 pa_dev.c PortAudio sound library initialized, status=0 17:27:09.203 pa_dev.c PortAudio host api count=2 17:27:09.203 pa_dev.c Sound device count=15 17:27:09.204 pjlib select() I/O Queue created (0x8e8fd5c) 17:27:09.204 wav_player.c File player 'test.wav' created: samp.rate=11025, ch=1, bufsize=4KB, filesize=304KB 17:27:09.204 pa_dev.c PA message: Expression 'SetApproximateSampleRate( pcm, hwParams, sr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1294 17:27:09.204 pa_dev.c PA message: Expression 'PaAlsaStreamComponent_InitialConfigure( &self->playback, outParams, self->primeBuffers, hwParamsPlayback, &realSr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1873 17:27:09.204 pa_dev.c PA message: Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters, sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1994 17:27:09.204 playfile.c Unable to open sound device: Invalid sample rate [code=469996] Does anyone know the appropriate wave file format? -- Edgar Acosta eacosta at hcn-inc.com Software Developer 1 613 216 1495 x 6225 (ET) The Hotel Communication Network Inc. www.hcn-inc.com
