Transcode MPEG2 for IOS ok, rtmp /rtsp black screen

Wowza Streaming Engine
1

We have wowza Media Server 3.1.1 build1479 with transcoder addon, we are pushing MPEG2 streams to the wowza server and transcoding fine for IOS but rtmp and rtsp have black screens.

strings look like this

rtmp://27.50.xx.xx/transcode/mpegts_bom.stream (Black Screen on pc browser)

rtsp://27.50.xx.xx/transcode/mpegts_bom.stream (Black Screen Andriod 4)

http://27.50.xx.xx/transcode/ngrp:mpegts_bom.stream_all/playlist.m3u8 (fine on ipad)

transcode template is standard.

Stream Manager

transcode/definst

Streams:

mpegts_bom.stream[stop receiving stream][reset receiving stream]

Groups:

mpegts_bom.stream_all[remove stream group]

360p

160p

720p

mpegts_bom.stream_mobile[remove stream group]

160p

Any ideas where to locate the problem

Have transrate setup and works fine based on same strings above IOS, RTMP and RTSP

Any clues in the Wowza logs?

Can you describe your source stream? You can use ffprobe from the ffmpeg package:

ffprobe -show_streams [media]

You can also try posting the info for the working and non-working Wowza transcoder/transrated streams.

What do you mean, “pc browser”? You need a Flash player to playback rtmp. Are you using a player?

I’m not sure what you mean by “Flash for PC browser”. Try testing with Wowza example Flash player:

[wowza-install-dir]/examples/LiveVideoStreaming/client/live.html

Rob,

Restart Wowza, then test playback using the Wowza example player. Then zip up and send the conf folder and current access and error logs to support@wowza.com.

Also send /content/mpegts_bom.stream. What are the encoding details of that source, the audio and video codecs?

Are you using the Wowza Transcoder? If so, zip up and send the /transcode folder also.

Include a link to this thread for reference.

Richard,

Yes flash for PC browser, stream is originating from a ASI to IP gateway see wireshark details of stream ISO/IEC 13818-1 PID=0x201 CC=9

Can we send the logs to you?

Richard,

Sorry the player in the browser was Flowplayer, we tested with the [wowza-install-dir]/examples/LiveVideoStreaming/client/live.html see log extract below.

We found no error displayed in the live.html but also no picture or audio
