的GStreamer flvmux和RTMP錯誤

我試圖從rasberrypi RTMP流，該OMX硬件編碼器的工作非常不錯，對了，所以我跑：的GStreamer flvmux和RTMP錯誤

gst-launch-1.0 v4l2src ! «video/x-raw,width=640,height=480,framerate=30/1» !\ 
omxh264enc target-bitrate=1000000 control-rate=variable !\ 
video/x-h264,profile=high ! h264parse ! queue ! \ 
flvmux name=mux alsasrc device=plughw:1 ! audioresample ! \ 
audio/x-raw,rate=48000,channels=1 ! queue ! voaacenc bitrate=32000 ! queue ! mux. mux. !\ 
rtmpsink location='rtmp://my_rtmp_for_ustream.tv_url'

而且有一個錯誤：

Setting pipeline to PAUSED ... 
Pipeline is live and does not need PREROLL ... 
Setting pipeline to PLAYING ... 
New clock: GstAudioSrcClock 
ERROR: from element /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Internal data flow error.

首先我認爲有一些問題，ALSA或者這樣，後來我試着寫簡單MPEGTS的，它的工作：

gst-launch-1.0 v4l2src ! «video/x-raw,width=640,height=480,framerate=30/1» ! \ 
omxh264enc target-bitrate=1000000 control-rate=variable !\ 
video/x-h264,profile=high ! h264parse ! queue ! \ 
mpegtsmux name=mux alsasrc device=plughw:1 ! audioresample !\ 
audio/x-raw,rate=48000,channels=1 ! queue ! voaacenc bitrate=32000 ! \ 
queue ! mux. mux. ! filesink location=1.ts

但我不能只是改變「文件接收地點= 1.ts」到rtmpsink位置=「RTMP：//my_rtmp_for_ustream.tv_url」因爲我會得到一個錯誤：

警告：管道錯誤：無法連接複用到rtmpsink0

那麼，我能做些什麼來得到它的工作？謝謝。

真正的問題是rtmpsync需要原始的AAC，所以我加了aacparse和它的工作了，這樣的事情：

gst-launch-1.0 v4l2src ! \ 
    "video/x-raw, framerate=25/1, width=320, height=240" ! \ 
    omxh264enc target-bitrate=300000 control-rate=variable ! \ 
    h264parse ! queue ! flvmux name=muxer alsasrc device=hw:1 ! \ 
    audioresample ! "audio/x-raw,rate=48000" ! queue ! \ 
    voaacenc bitrate=32000 ! aacparse ! queue ! muxer. muxer. ! \ 
    rtmpsink location="$RTMP_URL"

rtmpsink需要「video/x-flv」格式的數據。你的第一條管道清楚地顯示出談判錯你可以通過在命令行中添加-v來獲得管道協商轉儲的管道。
