debian ffmpeg網絡攝像頭流式傳輸到遠程服務器錯誤

Question

我有一個beaglebone黑色，我試圖將流媒體直播到OSX電腦。如果我將它指向本地ffserver，流式客戶端藥水似乎可行。

但是，如果我點它在遠程（我的電腦）ffserver的它拋出一個錯誤

它會在此AVCodecID枚舉的141nd編解碼器是AV_CODEC_ID_VP8/AV_CODEC_ID_PICTOR取決於是否AV_CODEC_ID_MPEG2VIDEO_XVMC是否定義？ https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/avcodec.h

還包括我的ffserver配置。

MaxClients 1000 
MaxBandwidth 10000

反正我不知道如何解決這個問題。任何指針將不勝感激。

你是否試圖檢查問題是否是服務器端？你有沒有在http://192.168.200.40:8090中使用ping？服務器響應？我說這是因爲它可能是由防火牆問題引起的，例如。
