Transcoding rtsp streamed mp4 to h.264 (rtsp

I am trying to isolate a problem with decode of rtsp streamed mp4 data through EMS. As part of this process I am attempting to use evo-avconv (with the intention of using launchprocess eventually) to convert an rtsp streamed mp4 version of the standard big bunny video at 640 res. I am using vlc as rtsp server. Where am I going wrong with this command-line implementation of the conversion?

$ /bin//evo-avconv -f rtsp -i rtsp://127.0.0.1:8554/stream_raw -c:v libx264 -c:a libfaac -b:v 1000k -f rtsp -metadata title=stream_h264 rtsp://127.0.0.1:9544/stream_h264

I can confirm that my installation is capable of converting the mp4.
