<div>Hello everyone,</div>
<div><br>
</div>
<div>I'm trying to start a stream on Wowza programmaticaly by
feeding the stream myself with packets comming from GStreamer.</div>
<div>Wowza provides an API called "Publisher API" :
(<a class="gmail-m_2155099440117251484gmail-m_-8653466576254998529m_3341666876865109683moz-txt-link-freetext" href="http://www.wowza.com/resources/serverapi/4.5.0/com/wowza/wms/stream/publish/Publisher.html" target="_blank">http://www.wowza.com/resource<wbr>s/serverapi/4.5.0/com/wowza/wm<wbr>s/stream/publish/Publisher.htm<wbr>l</a>)</div>
<div>it enables you to publish a stream on Wowza with Java Code
by feeding the stream with byte[] (packets).</div>
<div>What I'm trying to do is to read a mkv file on disk with
gstreamer and send packets to Wowza using this API.</div>
<div>My Problem is that Wowza seems to doesn't recognize what's
inside the packet I'm sending, see logs : </div>
<div><br>
</div>
<div>Audio codec:PCM_BE isCompatible:false</div>
<div>Video codec:UNKNOWN[0] isCompatible:false</div>
<div><br>
</div>
<div>For information my video and audio packets are in h264 and
aac codecs. it is 2 format that Wowza knows to read.</div>
<div>I Think, maybe the packets coming from GStreamer can't be
sent to Wowza directly without some king of transformation or
adaptation.</div>
<div>On the Publisher API page, there is the format of the
packets for aac and h264 that is described. I don't know if
GStreamer is already sending me the video and audio packets</div>
<div>respecting this format or if I have to do something myself
with gstreamer packets before giving it to Wowza.</div>
<div><br>
</div>
<div>For more detail, this is the GStreamer Pipeline I'm using :</div>

<div>I'm trying to repacketize data coming from Gstreamer
(AppSink buffers) before sending it to Wowza.<br>
Threre is a description of Wowza Packets requirements on this
page:
<a class="gmail-m_2155099440117251484gmail-m_-8653466576254998529m_3341666876865109683moz-txt-link-freetext" href="http://www.wowza.com/resources/serverapi/4.5.0/com/wowza/wms/stream/publish/Publisher.html" target="_blank">http://www.wowza.com/resources<wbr>/serverapi/4.5.0/com/wowza/wms<wbr>/stream/publish/Publisher.html</a><wbr>.<br>
And I need for Video Packets to know the type of frame (Key, P
or B) to set it in the Wowza header.<br>
