It focuses on the high-level During a call, media components are managed by PJSUA-LIB, when PJSUA-LIB or PJSUA2 is used, or by the application if the application uses low level PJSIP or PJMEDIA API directly. c . It covers common audio issues including dropouts, noise, jitter, and acoustic Using the system test executable pjsip-apps/bin/pjsystest-armv7l-unknown-linux-gnueabihf I can enumerate the audio devices: 1:OK. I get this error when I try to establish a new call from pjsip: pjsua_aud. To Reproduce Launch pjsystest-armv6l-unknown-linux-gnueabihf Expected behavior List of detected This enumeration identifies various audio device capabilities. I I may select the device for example for output i may use pc speakers (n_outDevice=1) and for input i may use USB sound device (n_inDevice=0). I didn't use callKit, I customized the call UI and I used the library based on PJSIP stack (http://www. Hence connecting a media to port zero will play that media to speaker, and connecting port zero to a By default it is taking usb audio codec as playback and capture device. For information about call An important subclass of Media is AudioMedia which represents audio media. Error retrieving default audio device parameters: Unable to find default audio device Describe the bug Fail to detect audio devices. c) I am finding that the application Route to paired Bluetooth device enumerator PJMEDIA_AUD_DEV_ROUTE_CUSTOM Custom audio route/source, specific to each audio device backend. Identify the sound problem and troubleshoot it using the steps described in: Checking for sound problems. I can't make a call without adding a PJSUA has rather powerful media features, which are built around the PJMEDIA conference bridge. . pjsip. But trying to generate a sound fails: This test will play Follow the guide: Test the sound device using pjsystest. 8 release Follow the guide: Test the sound device using pjsystest. There are several type of audio media objects supported in PJSUA2: Capture device’s AudioMedia, to capture audio from the This happens when PJSUA-API receives incoming INVITE request with Replaces header. This document covers the audio media system in PJSUA2, including the conference bridge architecture, audio media classes, and audio flow management. As we read that this issue is fixed in 2. setNullDev() because the machine I'm running the code on doesn't have an audio interface and PJSUA crashes when I The numbers 0-2 are one card (hw:0,x) The number 3 is the USB card (hw:1,x) The numbers 4-12 are created by default in ALSA, and probably will use only the first card. After this callback is called, normally PJSUA-API will disconnect old_call_id and establish new_call_id. I can't add a buddy, I get an exception that mentions one of the C code files. These audio capabilities indicates what features are supported by the underlying audio device implementation. FEATURES - Session Initiation Protocol (SIP) features: - Basic registration and call - Multiple accounts - Call hold, attended and unattended call The issue is that I am unable to disable the device before initialization of pjsua. It covers audio and video media operations, device management, media configuration, and common tasks for implementing multimedia applications. Basically, all media “ports” (such as calls, WAV players, WAV playlist, file recorders, sound device, As per instructions, before initiating a call we configure our Audiosession and set the pjsip no device set and again set the devices with (-1,-1). As a convention in PJSUA-LIB API, port zero of the conference bridge is denoted for the sound device. It is probably easier to do the testing 1- When setting a specific audio device that I would like used on calls using pjsua_set_snd_dev (pjsua_aud. audDevManager(). org) 1. I tried with pjsua_set_no_snd_dev and pjsua_set_null_snd_dev, but it is to be called after pjsua_init and at the The sound device may be inactive if the application has set the auto close feature to non-zero (the sndAutoCloseTime setting in MediaConfig), or if null sound device or no sound device has been Symbian audio streaming/multimedia framework (MMF) Nokia Audio Proxy Server (APS) null-audio implementation Supported Video Devices Supported capture devices: Android Camera2 AVI virtual The PJSUA2 Python sample application (pygui) is broken out of the box. These devices are not physical . Then i call pjsua_set_snd_dev This page provides systematic troubleshooting approaches for audio-related problems in PJSIP applications. I would like to change default playback and capture audio device in pjsip library to usb audio codec and IQAudio DAC which is connected externally to Raspberry pi compute module 3+ . Applications get these If any capture or playback device ID is set to PJSUA_SND_NULL_DEV (for null audio device), PJSUA will invoke pjsua_set_null_snd_dev() so both device IDs will be reset to Describe the bug I successfully compiled the PJSIP iOS library and supported TLS, which was fine until I started actual development. For Android JNI audio device, the default is Info: You can set the device settings when opening audio stream by setting the flags and the appropriate setting in pjmedia_aud_param when calling pjmedia_aud_stream_create () I have set ep. Can anyone help me? Thanks in advance. How can we change the audio devices from default to desired ones.
