  1. POConstant Buffering & Audio/Video Out of Sync RTMP Streaming
    text
    copied!<p>I am attempting to establish a high quality RTMP stream using Flash Media Live Encoder and Flash Media Server which is installed on my CentOS VPS Host. I am able to connect to the stream with the following url in the encoder: rtmp://myhost:1935/live/streamname (this is example).</p> <p>I am using Flash Media Playback and embedding the following html for video playback:</p> <pre><code>&lt;object width="640" height="480"&gt; &lt;param name="movie" value="http://fpdownload.adobe.com/strobe/FlashMediaPlayback.swf"&gt; &lt;/param&gt; &lt;param name="flashvars" value="src=rtmp%3A%2F%2Fmyhost%3A1935%2Flive%2Fstreamname&amp;poster=http%3A%2F%2Fsquarestream.ca%2Fpics%2Fframe.jpg&amp;autoPlay=true&amp;streamType=live&amp;optimizeInitialIndex=false"&gt;&lt;/param&gt; &lt;param name="allowFullScreen" value="true"&gt;&lt;/param&gt;&lt;param name="allowscriptaccess" value="always"&gt;&lt;/param&gt; &lt;embed src="http://fpdownload.adobe.com/strobe/FlashMediaPlayback.swf" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="480" flashvars="src=rtmp%3A%2F%2Fmyhost%3A1935%2Flive%2Fstreamname&amp;poster=http%3A%2F%2Fsquarestream.ca%2Fpics%2Fframe.jpg&amp;autoPlay=true&amp;streamType=live&amp;optimizeInitialIndex=false"&gt;&lt;/embed&gt;&lt;/object&gt; </code></pre> <p>The problem I am having is that the video is consistently buffering (approx every 5 seconds), followed by a sped up video playback and the audio and video is never in sync. From everything I have read, my encoder settings are fine: </p> <p>25 FPS, 500 Kbps bitrate video, 128 kbps audio, I am on internet connection averaging 6 MBPS upload, my CPU/RAM usage never above 75% as Adobe suggests. I fear the issue is my hosting, but I am at a loss, I have tried every conceivable encoder setting, and as far as I know, FMS is setup correctly on host, and can verify stream connects in the admin console. Any suggestions would be helpful. </p> <p>Thanks. </p>
