streaming elementary h264 over mpegts/rtp

Wowza Streaming Engine
1

Hi,

I would like to stream a .264 file over mpegts/rtp using gstreamer pipeline to wowza server.I’m able to do this if i reencode the 264 file using x264enc plugin of gstreamer.

The pipleline used is

gst-launch -v filesrc location=/home/riversilica/New_Driver_Aio/MMap_read/ttest/test_107mb.264 ! decodebin ! x264enc ! video/x-h264 ! mpegtsmux ! rtpmp2tpay ! udpsink host=192.168.2.108 port=10000

Even If i store the output of x264enc and use that file to stream to wowza,im not able to receive it.

What is the way wowza is expecting the packets which contain h264?

Can you let me know how the x264enc in pipeline is able to send the packets to wowza as per wowza’s requirement.

Thank you

We do not have much experience with GStreamer so we will most likely not be much help.

It looks like this MPEG-TS stream is not properly aligned. Some muxers do not properly start each new RTP packet on a new MPEG-TS sub-packet. This can lead to this warning in the logs. We do not have way to work around this. What encoder is being used for this stream?

It should but this is MPEG-TS over RTP. With MPEG-TS over RTP a single RTP packet will container more than one 188 byte MPEG-TS packet. Some muxers will not properly start each RTP packet with a new MPEG-TS packet. They will instead break 188 byte MPEG-TS packets mid-packet.

Thank you…

We just wan2 stream a raw h264 in mpegts over rtp. So is there any specific way wowza expects the packets. Even without gstreamer if there’s any other method let us know.

I get this in the log

The encoder is gstreamer x264enc plugin. (h264 encoder). So if i sent one NAL unit of 264 to mpegts,will it be recognized by wowza as valid packet. One mpegts packet is 188 byte packet
