<div class="WordSection1">
<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">I am converting the following simple pipeline to C code but it is not working. This receiver pipeline works just fine using the launch tool which shows that my test environment is set up correctly.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">udpsrc address="192.168.1.101" port=5018 ! fakesink dump=TRUE<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Attached is my C code snippet. My bus_call message handler [not included] prints out the pipeline state changes. I used visual studio 2010 to compile the C code. Here is the run time screen capture.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraphCxSpFirst">GST_STATE_CHANGE_ASYNC for udp recv.<o:p></o:p></p>
<p class="MsoListParagraphCxSpMiddle"><o:p> </o:p></p>
<p class="MsoListParagraphCxSpMiddle">Running...<o:p></o:p></p>
<p class="MsoListParagraphCxSpMiddle"><o:p> </o:p></p>
<p class="MsoListParagraphCxSpMiddle">Pipeline state changed from NULL to READY.<o:p></o:p></p>
<p class="MsoListParagraphCxSpMiddle"><o:p> </o:p></p>
<p class="MsoListParagraphCxSpLast">Pipeline state changed from READY to PAUSED.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, the return from setting the pipeline to playing is the ‘async’ state change. As I understand it, this means that pipeline state changes may be delayed. However, for my simple test case the pipeline
<u>never</u> goes to the PLAYING state. The pipeline just sits there in the PAUSED state and data never flows to the display. For my test case I start the receiver first, then the sender which runs on a separate machine.
<o:p></o:p></p>
<p class="MsoNormal">I’m using GStreamer 1.8.1 with your windows pre-built binaries on my windows 7 machines.
<o:p></o:p></p>
<p class="MsoNormal">I’m probably tripping over something simple. Any ideas on what I might be doing wrong?<o:p></o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
<p class="MsoNormal">Bill <o:p></o:p></p>
