1.遇到的问题
今天遇到linphone-android sdk需要解决语音编码问题，需要指定编码。查了下配置，里面没有发现类似的配置。
Start of factory rc

End of factory rc
2.解决方法
- 查看linphone安卓端支持的编码
- 查到一个指定编码的方式，之后试了下是可以的
-
根据自己的需要调整参数
//音频部分, 这里增加了一个遍历, 用于设置指定的音频格式.
//h264, no VP8 fixed outgoing call no video.
//音频部分, 这里增加了一个遍历, 用于设置指定的音频格式.
//h264, no VP8 fixed outgoing call no video.
val payloads: Array= core.audioPayloadTypes
for (i in payloads.indices) {
//Payload:null, VP8/90000/0, A VP8 video encoder using libvpx library., VP8
//Payload:profile-level-id=42801F, H264/90000/0, A H264 encoder based on MediaCodec API., H264
val pt: PayloadType = payloads[i]
//判断是否指定的音频格式.我这里指定PCMA格式
val goodPayload: Boolean = "PCMA" == pt.mimeType
pt.enable(goodPayload)
}
