Windows/Linux/Android/iOS平臺RTMP功能元件EasyRTMP-Android,推流H264到SRS無法播放原因是什麼?
SRS伺服器是定位於網際網路直播伺服器叢集的開源框架,TSINGSEE青犀視訊研發團隊也會拿SRS伺服器來進行流媒體服務的研發和對比。我們可以推送RTMP到SRS、推送RTSP/UDP/FLV到SRS、拉取流到SRS,同時SRS還支援將接入的RTMP流進行各種變換,譬如將RTMP流轉碼。
研發人員用EasyRTMP-Android測試伺服器推流功能時,選擇了推流到SRS伺服器,但是視訊流播放不了,並且出現如下圖的報錯:
因為RTMP協議的原因,推流庫在只推流視訊時,預設會加上無聲的音訊,取樣率是8000HZ,但是SRS伺服器處理不了這個取樣率的音訊,所以需要改成44.1kHZ的音訊,SRS伺服器才能處理。
原來的音訊格式是這樣的:
// 取樣率8k的音訊資料
