Has Anyone Been Successful in Streaming From Gstreamer to a Wowza Server in Windows?

payloading is done during transmission. The audio video encoding can be
done during transmission, as in my previous example, or encoded before.
This second option saves CPU since encoding is done only one time, not
each time a client access the stream.

To do that:
1) Encode the video file to be streamed:
gst-launch filesrc location=<your video file> ! decodebin2 ! x264enc \
bitrate=500 ! ffmux_ipod ! filesink location=encoded_video_file.mp4

2) Encode the audio file:
gst-launch filesrc location=<your audio file> ! decodebin2 ! faac ! \
ffmux_ipod ! filesink location=encoded_audio_file.mp4
 
3) lunch the RTSP server as follow:
./test-launch "( filesrc location=encoded_video_file.mp4 ! qtdemux ! \
h264parse ! rtph264pay name=pay0   \
filesrc location=encoded_audio_file.mp4 ! qtdemux ! aacparse ! \
rtpmp4gpay name=pay1 )"

Also to be more specific, "repacked" means that wowza is not re-encoding
audio and video, but just converting network packet header the
appropriate format during transmission, depending on which protocol the
client access the wowza server (Flash streaming or others).
