如何使用Android Pjsua 2暂停和取消暂停视频传输? [英] how to pause and unpause video transmission using Android Pjsua 2?

问题描述

我希望在飞行中进行视频通话时暂停和取消暂停视频传输，而不会使用Android Pjsua2库删除音频通话.但是有些我无法理解如何实现该功能以示例android pjsua2应用程序.任何帮助将不胜感激.

I wish to pause and unpause video transmission in video call on fly without dropping Audio call using Android Pjsua2 library. But some how i am not able to understand how to implement that feature to sample android pjsua2 app. Any help would be highly appreciated.

我仔细阅读了以下文档，但无法理解..如何实现

i went through below documentation and not able to understand ..how to implement it

枚举pjsua_call_vid_strm_op此枚举表示视频流通话中的操作.

enum pjsua_call_vid_strm_op This enumeration represents video stream operation on a call.

PJSUA_CALL_VID_STRM_START_TRANSMIT开始传输视频流.这将导致先前停止的流再次开始传输.请注意，由于以下原因，任何re-INVITE/UPDATE都不会传输到远程此操作仅在本地流上进行.

PJSUA_CALL_VID_STRM_START_TRANSMIT Start transmitting video stream. This will cause previously stopped stream to start transmitting again. Note that no re-INVITE/UPDATE is to be transmitted to remote since this operation only operates on local stream.

PJSUA_CALL_VID_STRM_STOP_TRANSMIT停止传输视频流.这将导致流在TX方向上暂停，从而导致停止发送任何视频数据包.不得重新邀请/更新通过此操作传输到远程.

PJSUA_CALL_VID_STRM_STOP_TRANSMIT Stop transmitting video stream. This will cause the stream to be paused in TX direction, causing it to stop sending any video packets. No re-INVITE/UPDATE is to be transmitted to remote with this operation.

推荐答案

请考虑以下代码:

fun strmStopTransmit() {
    if (manager.isCaptureActive(camDevId)) {
        val callVidPrm = CallVidSetStreamParam()
        callVidPrm.setCapDev(camDevId)
        call.vidSetStream(pjsua_call_vid_strm_op.PJSUA_CALL_VID_STRM_STOP_TRANSMIT, callVidPrm)
    }
}

其中 manager 是 pj :: VidDevManager 的实例(链接).

Where manager is instance of pj::VidDevManager (link) (you can get it from pj::Endpoint (link)) and call is instance of pj::Call (link).

反函数(继续传输)的实现是显而易见的.

The implementation of the inverse function (resuming transmission) is obvious.
