Gstreamer：ビデオとオーディオをrtmpsinkにmuxできない

Question

ビデオとオーディオのテストソースをrtmpsinkにmuxしようとしています。このパイプラインは動作しません：私は、別途オーディオとビデオを押せばそれが動作

Setting pipeline to PAUSED ... 
Pipeline is PREROLLING ... 
Redistribute latency... 
Pipeline is PREROLLED ... 
Setting pipeline to PLAYING ... 
New clock: GstSystemClock 

：

gst-launch-1.0 \ 
videotestsrc ! queue ! x264enc ! \ 
flvmux name=mux ! \ 
rtmpsink location="rtmp://... live=1" \ 
audiotestsrc ! queue ! audioconvert ! mux. 

私はこのコンソールの結果を取得しています

gst-launch-1.0 \ 
videotestsrc ! queue ! x264enc ! \ 
flvmux name=mux ! \ 
rtmpsink location="rtmp://... live=1"

シンプルだったそれをMPEGに再エンコードすることで動作させました。

gst-launch-1.0 videotestsrc is-live=true ! videoconvert ! queue ! \ 
x264enc bitrate=2000 ! \ 
flvmux name=mux ! \ 
rtmpsink location="rtmp://localhost/test/test live=1" \ 
audiotestsrc is-live=true ! queue ! faac ! mux. 

NGINX RTMPサーバーとクライアントとしてVLCに対してこのパイプラインをテストしました。私は、生のオーディオがうまくいかない理由を完全には分かっていません。
