<p class="MsoNormal"><span lang="EN-GB">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I want to mix multiple video streams into one picture.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Therefore I use the compositor element. I can mix two videos and it seems to work fine (written in C).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">One requirement is, to mix only one to up to four (quad view) videos.
<br>
Just for a quick test I only added one video source, started the pipeline and later, while the video was running, I called gst_element_get_request_pad(pData->m_pElMixer, "sink_%u"); which leads to stop the pipeline.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Can that be done this way or do I need to add all four sink pads with fake sources to the compositor before starting and replacing them later?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Kind Regards<o:p></o:p></span></p>
