streaming h264 to silverlight

[bzuidgeest]

I'm trying to get create a h264 video aac audio stream that is acceptable to silverlight.

The following links describes the video support in silverlight mediaelement.
http://msdn.microsoft.com/en-us/library ... s.95).aspx

Under the heading h264 If find the following:
Desktop Silverlight only supports the Annex B NAL format (i.e. start codes).
I do not know what this means exactly, except that it seems to mean something related to the container of the stream.

I use the following settings to stream
:sout=#transcode{vcodec=h264,vb=0,scale=0,acodec=mp4a,ab=128,channels=2,samplerate=44100}:http{mux=ffmpeg{mux=flv},dst=:8080/} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep

the source is an axis p1346 ip camera that outputs h264 video and g711 audio
rtsp://10.190.90.11:554/axis-media/media.amp?audio=1&videocodec=h264&resolution=1280x720

When I open the vlc stream in vlc it works fine, but silverlight just switches it's state to opening and then nothing. I read somewhere that silverlight requires to start on a keyframe or something like that.

Is there someone on this forum that has experience streaming h264 video to silverlight? Are the settings to adjust relating to the annex b thing or any working out string? I tried transcode to wmv which some success, but then it turn into a blocky mess. That is a waste of a full hd ip camera

Hi, did you ever find out how to do this? I'm doing the same with SL 4 and an Axis RTSP H.264 video stream.

Are you sure SL4 supports flv? (hint: I doubt it)
