Comments on: Using VLC to transcode an Axis Camera’s video stream, and stream it out again http://johnbeales.com/20080820/using-vlc-to-transcode-an-axis-cameras-video-stream-and-stream-it-out-again/ Mon, 22 Feb 2010 03:03:19 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: John http://johnbeales.com/20080820/using-vlc-to-transcode-an-axis-cameras-video-stream-and-stream-it-out-again/#comment-27092 John Thu, 03 Sep 2009 19:42:41 +0000 http://johnbeales.com/?p=123#comment-27092 It's been a while, but I think that I copied the .sdp file from the camera, edited a couple of lines, and gave that to Darwin. Check out <a href="http://custforum.axis.com/viewtopic.php?t=402" rel="nofollow">this thread</a> in the Wowza forums, and the web page that is linked in the thread. They deal with getting Darwin to stream from some Axis cameras. It’s been a while, but I think that I copied the .sdp file from the camera, edited a couple of lines, and gave that to Darwin.

Will Darwin stream it directly and if so will it support multiple cameras? Any help is appreciated, Thanks, Robert. John,

Most of the problems seem to stem from the fact that the camera is remote, and we have to use an RTSP stream as input, but if a codec change can help things, and if that codec is still flash-compatible, that would be great news.

I can stream and transcode it using H.264. But I can do it using Dirac codec. How do you think about it??!!Thank for ur suggestion :) I have logitech quickcam notebook pro camera and i use vlc-1.0.0-rc3 in windows XP. I can stream and transcode it using H.264.

Maybe the Axis 241S makes a better stream than the old 207/210 cameras. What version of VLC are you using? That’s excellent news.

I am running a Axis 241S video server, this video server doesn't have any support for h.264, but thanks to your info it's working through Wowza.

At this point, if buying cameras for web streaming, I recommend buying an h.264-capable camera. The cost involved in transcoding will cost more than the price difference in the cameras. If there's a large inventory of older cameras, especially if the replacement cost is high, this may still apply, but it is probably in the buyer's best interest to try to find an economical hardware-based transcoder. It will most likely have a lower total cost of ownership and have fewer problems.

Now that AXIS are selling h264 cameras, has all of this topic been resolved - ie an AXIS camera can generate the right type of stream for Flash Media Server to handle without any modification? Thanks for your article. Paul C. Hi John.

Alternatives are to use Active-x (IE only) or require quicktime. I think flash is more universal. I agree that for large scale viewing a fat server would be needed, but for one or two viewers something small scale would be all that is needed. I'm going to look into it to see if I can hack something up, I haven't quite grasped all the encapsulation of H.264 inside RTMP yet, and ultimately I'd like to use RTMPT as running multiple ports on a device make it hard to share via port forwarding or advanced technologies like Yoics in a flexible manner.

I'm not aware of any camera that has one at the moment, but I don't know all of the cameras on the market. The problem with working this way is that many cameras don't have a high-bandwidth connection to the internet, but in situations where they do it may work well. If you're able to get it working let me know for sure! You’re right – the camera would have to have a built-in RTMP server.
