How to fix black screen when call is answered and loss packs on H264

由 允我心安 提交于 2019-12-11 11:53:58
问题 I am developing VOIP app using linphone IOS/Android library. Basically I used OpenH264 video codec. When call is answered, both side saw black screen. After long time, both size can see the video each other. When I see the log, there are many packets loss so that First frame can not be decoded. At LinphoneCallStreamsRunning, I called FIR (linphone_call_send_vfu_request) request but not helped. Is there any config for OpenH264 video codec? I want to see the video as soon as accept call. Thank

Force using just OPUS codec in Linphone Android

由 你说的曾经没有我的故事 提交于 2019-12-11 03:24:11
问题 How can I force to use just Opus Codec in linphone ? Is there a setting in LinphoneManager.java, or somewhere else (like in LinphoneCore) to change codec setting ? I found this code in LinphoneManager.java : enableDisableAudioCodec("speex", 32000, 1, false); enableDisableAudioCodec("speex", 16000, 1, false); enableDisableAudioCodec("speex", 8000, 1, true); enableDisableAudioCodec("iLBC", 8000, 1, false); enableDisableAudioCodec("G722", 8000, 1, false); enableDisableAudioCodec("G729", 8000, 1,

Linphone for iOS

由 妖精的绣舞 提交于 2019-12-10 17:51:56
问题 I need to build linphone for iOS (and android and windows after that, but that is of later concern). Since no one is able to answer my previous question nor a similar one, can someone at least point me to a good resource on the subject? I feel like I tried everything already, and the project still won't compile (lot's of files missing, include paths are wrong, libraries can't be found etc...). Linphone doesn't have a forum as far as I know, and any threads I find on the internet are

用freeswitch架设局域网内sip电话

FreeSWITCH 是一个电话的软交换解决方案，包括一个软电话和软交换机用以提供语音和聊天的产品驱动。FreeSWITCH 可以用作交换机引擎、PBX、多媒体网关以及多媒体服务器等。 首先保证已经有libjpeg-devel,libtoo,libncurses5,libncurses5-dev git clone git://git.freeswitch.org/freeswitch.git cd freeswitch ./bootstrap.sh 如果要测试IVR的话，需要修改modules.conf，找到mod_flite的行，把它的注释去掉 ./configure make make install 然后需要安装语音文件 sounds-install moh-install (8 kHz) hd-sounds-install hd-moh-install (16 kHz) uhd-sounds-install uhd-moh-install (32 kHz) cd-sounds-install cd-moh-install (48 kHz) 选一个，8 kHz是普通电话的音质，越高越好 make sounds-install moh-install 下载安装完后就算完成了 运行/usr/local/freeswitch/bin/freeswitch开启服务器，要关闭的话

Integrate linphone into iOS

由 不问归期 提交于 2019-12-06 04:27:20
I am trying to add linphone lib to my existing iOS app, but it fails to build My process: Added all the required frame works in my existing project. Copied all lib from linphone-iphone/liblinphone-sdk/apple-darwin/lib/ to myproject/lib Copied linphone-iphone/Resources to myproject/Resources Then I added LinphoneManager.h & .m with there related files. Then I started build the app, I am getting file not found #include "ortp/ortp.h" in Linphonecore (but file is available). What I understand from the error is, I need to modify the build setting to search the file. I have done that but I still get

Android SIP application using Linphone

由 血红的双手。 提交于 2019-12-05 05:22:08
I am working on SIP application and using Linphone Library i have a little confusion while setting up the library to run the project. Step 1: Firstly I Downloaded NDK on my Mac with the new Android SDK pkg. Then gaved the PATH of my NDK folder in ADT -> Preferences -> Android -> NDK Step 2: Then i installed Autotools using this link (Only Followed Commands written under point: 2.3 How do I install the Autotools (as user)?) ndk_build Step 3: After that i downloaded linphone-android using Terminal using - git clone git://git.linphone.org/linphone-android.git --recursive Now i want to follow

Linphone compiling problems on osx

I'm trying to compile linphone on mountain lion. I have downloaded the sources and followed all the instructions in the README.macos file. The first time, when I got to '$ port install ige-mac-integration' an error occurred. It said gtk2 had to be installed with x11, however, the instructions said to install it with quartz and no_x11. I tried installing gtk2 again, this time with x11, but when I get to the compiling process it tells me quartz is needed. I can't install both, because the gtk2 installation will complain about it, and it seems I need both to complete the entire process of
