    Default Restreaming MPEG-TS

    I have one MPEG-TS stream receiving by Wowza via one file in content folder
    stream1.stream (with contents udp://239.0.1.11:2000)
    and started in StatrupStreams.xml with
    		<StartupStream>
    			<Application>live/_definst_</Application>
    			<MediaCasterType>rtp</MediaCasterType>
    			<StreamName>sream1.stream</StreamName>
    		</StartupStream>
    When that stream is being received, Wowza reports inbound traffic of ~6Mbps and that is ok (that agrees with propreties of stream).
    Stream properties are:
    Stream #0:0[0x210]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p, 720x576 [SAR 64:45 DAR 16:9], 5352 kb/s, 25.63 fps, 25 tbr, 90k tbn, 50 tbc
    Stream #0:1[0x310](ser): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16, 320 kb/s (clean effects)


    Problems start when I try to push stream out to one unicast address. I tried RTPPusher and MulticastPublish addon but without success, I got the same results.
    For example if I try to push stream to 192.168.0.10:1000 outbound network traffic is 320Kbps (and inbound remains the same, ~6Mbps). On PC with 192.168.0.10 I looked with TS reader and it really shows only audio stream.

    If I try to pull stream1.stream out of Wowza via VLC player (rtsp://wowza_ip/appname/stream1.stream) I also have only audio but no video....


    What am I doing wrong? Is there any better way to restream MPEGTS?

    The video codec has to be h.264. The Wowza Transcoder supports mpeg2 for ingest/decode

    Richard thanks for quick reply.


    Wowza can not just restream intact mpeg ts (no matter of a/v codecs)? (multicast receive on one end and push to unicast on other)

    Without the encoder involved, Wowza only support h.264 video ingest
