title: ffmpeg settings or alternatives to ffmpeg on raspberry pi for video streaming
body: <p>I have a Raspberry Pi (model B) running raspbian wheezy on a 16gb SD card. I also have a 32gb flash storage attached on the usb. I'm trying to stream a video (h264 encoded mp4 file 1280x720) over the ethernet from that flash storage.
  <br/>
  I'm using ffmpeg+ffserver. Here is ffserver.conf (relevant parts):</p>
  
  <pre><code>...
  MaxBandwidth 10000
  &lt;Feed feed1.ffm&gt;
  ...
  FileMaxSize 100M
  ACL allow 127.0.0.1
  &lt;/Feed&gt;
  ...
  &lt;Stream test.flv&gt;
  Feed feed1.ffm
  Format flv
  VideoSize 288x176 #made small just for testing
  NoAudio
  &lt;/Stream&gt;
  ....
  </code></pre>
  
  <p>I start the ffserver, then call ffmpeg with this command:</p>
  
  <pre><code>ffmpeg -re -an -i /mnt/u32/main.mp4 -r 25 -bit_rate 300k http://localhost:8090/feed1.ffm
  </code></pre>
  
  <p>And I'm getting fps 3-5 at most. Naturally when I try to view the stream on another computer it's very choppy and virtually unusable.</p>
  
  <p>Am I missing some settings? Or perhaps there is another streaming solution that leverages the GPU instead of just the CPU as ffmpeg does? I'm even open to suggestions about other boards (e.g. a pandaboard? or clustering several RPi's?) Also, I'm flexible about the output format.</p>
