I’ve created a multicast rtp stream using ffserver, with the following configuration:

File /tmp/hikvision.ffm

FileMaxSize 10M

ACL allow 0.0.0.0 255.255.255.255

Launch ffmpeg -i “rtsp://192.168.71.68/h264/ch1/sub/” -s:v 1024x768

# Access with [http://localhost:8081/hikvision-rtp.sdp](http://localhost:8081/hikvision-rtp.sdp)

Feed hikvision.ffm

Format rtp

VideoFrameRate 5

VideoBitRate 4096

VideoBufferSize 8192

VideoSize 1024x768

MulticastAddress 224.124.0.100

MulticastPort 5000

MulticastTTL 16

NoAudio

This stream comes from a netcam. ffserver does multicast the stream and I can play it correctly from vlc (with the url [http://localhost:8081/hikvision-rtp.sdp](http://localhost:8081/hikvision-rtp.sdp)).

I then copied the sdp file to wowza, putting it in the content directory, and fired up the stream. So far so good.

I have the wowza transcoder enabled, and I can play via vlc the _transcoded_ resulting streams, via rtmp, in vlc. For example:

rtmp://localhost:1935/live/hikvision-rtp.sdp\_160p plays just fine.

I am not able to play: rtmp://localhost:1935/live/hikvision-rtp.sdp. For some reason that wowza stream doesn’t play in vlc.

My question is, why?

Thanks for help!!!
