<p>Hello,</p>
<p style="min-height:8pt;padding:0px"> </p>
<p>I try to make my own PCIE gstreamer source.</p>
<p>My goal is to feed an mpeg2ts stream to gstreamer pipeline on
my IMX8M som.(kernel 4.9.88)</p>
<p>In order to do that, i've created my own source based on
GstBaseSrc.</p>
<p>On many stream i get no problem....but on others my pipeline
doesn't want to work and it seems that MPEG2 parser is the
problem.</p>
<p>This is the log of the failure :</p></div></div></blockquote></div></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div text="#000000" bgcolor="#FFFFFF"><div class="m_-8548043190975939072jive-rendered-content">
