Hello,

I am having difficulty understanding how to configure Wowza and ffmpeg together. I am trying to transcode, on a local server, the MPEG-4 video coming from our old IP cameras (that do not spit out h.264) – then stream that up to the Wowza installation we have in the cloud (and in turn stream to our Flowplayer on our company website).

I have been following this support page:

https://www.wowza.com/docs/how-to-use-ffmpeg-with-wowza-media-server-mpeg-ts

Here is as much information as I can give you:

=== FFMPEG COMMAND

./ffmpeg -v verbose -i rtsp://[USER]:[PASS]@[CAMERA_IP]:[CAMERA_PORT]/mpeg4/media.amp -an -f mpegts -t 60 udp://[WOWZA_SIP]:[STREAM_PORT]

*NOTE – I have verified that the [STREAM_PORT] is open on our firewall.

=== STREAM FILE

Name: ffmpeg.stream 
URI: udp://0.0.0.0:9000

When I connect the test player (or create a Flow player) to

rtmp://[WOWZA_IP]:80/[app]/ffmpeg.stream

I get nothing happening on the screen – in flowplayer the spinning/loading graphic shows up over a black box. No image is ever shown. ON the test player, it says the stream is published, but nothing ever shows up.

The output from the FFMPEG command is as follows (when it is finished the 60 second stream):

No more output streams to write to, finishing.e=00:00:59.77 bitrate= 385.3kbits/s dup=2026 drop=0

  Total: 131 packets (340280 bytes) demuxed

  Output stream #0:0 (video): 2154 frames encoded; 2154 packets muxed (2476237 bytes);
  Total: 2154 packets (2476237 bytes) muxed

Note i am trying to accomplish this task as an alternative to the Wowza built-in transcoder.

Any help would be really appreciated. Thank you.

Hi,

The FFmpeg command you show does not do any transcoding. So the video will still be mpeg-4 part 2, which is not supported.

You do not mention starting the .stream file. You can use StreamManager or the Wowza Manager to start a stream, or add it to StartUpStreams and re-start Wowza to start pulling the stream.

You will use MediaCaster type “rtp” to start these streams by one of the methods above. When you do that you will see a publish event in the logs, and info about the connection and stream, or problems connecting to the stream.
