stream from mpeg ts encoder: video not working, audio OK

I am streaming from mpegts encoder multicast stream to wowza:

  • input stream udp://239.192.1.2:9001

-output stream: rtsp://x.x.x.x:1935/live/mpegts.stream

However audio is ok, but video is not working.

This is the message I get, and it seems video codec is ok:

LiveStreamPacketizerSanJose.handlePacket[live/definst/mpegts.stream]: Video codec: H264 - - - 238113.742 - - - - - - - - - - - - - - - - - - - - - - - - -

2012-11-26 09:03:03 CET comment server INFO 200 - LiveStreamPacketizerSanJose.handlePacket[live/definst/mpegts.stream]: Audio codec: MP3

and this is the error:

WARN 200 - RTPPacketFragmentListReader.skip: Bad skip count:

CPU is almost idle

Any idea?

I’m stuck here forever :frowning:

What is the source video and audio encoding details?

Play the source in VLC and check Tools > Codec Info

Then play Wowza rtsp output in VLC and check Tools > Codec info.

Try setting audioIsAligned to “false” in the Application.xml /RTP Properties container:

<Property>
	<Name>audioIsAligned</Name>
	<Value>false</Value>
	<Type>Boolean</Type>
</Property>

If that doesn’t work, follow this guide to make a recording and send to support@wowza.com

Hello Richard,

OK, the codec info from VLC:

Stream 0

Type Audio

Original ID:256

Codec: MPEG Audio Layer 1/2/3 (mpga)

Channels: Stereo

Sample rate: 44 kHz

Bitrate: 80 kb/s

Stream1

Type: Video

Original ID: 257

Codec: H264 - MPEG-4 AVC (part 10) (h264)

Resolutio: 704x576

Decoded format: Planar 4:2:0 YUV

and codec info from rtsp outpur in VLC:

Stream 0

Type Audio

Codec: MPEG Audio Layer 1/2/3 (mpga)

Channels: Stereo

Sample rate: 44 kHz

Bitrate 80 kb/s

A you can see - there is no vidio output in rtsp stream. And I can’t make out why because I don’t see any errors considering video in logs.

Anyone?
