There are basically no features available in passthrough mode, its just a left over legacy feature from before we had real video support. It doesn’t work very well and is not very useful if you want reliable video and any features for manipulating video content.<div class=""><br class=""></div><div class=""><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Feb 23, 2018, at 3:57 PM, Dom Rumsey <<a href="mailto:domrumsey@hotmail.com" class="">domrumsey@hotmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; background-color: transparent;" class=""><div style="margin: 0px;" class=""><font face="Calibri" size="3" class="">Hi</font></div><p style="margin: 0px;" class=""><font face="Calibri" size="3" class=""> </font></p><div style="margin: 0px;" class=""><font face="Calibri" size="3" class="">I’ve created a multiway video chat application using FreeSWITCH v1.6.20 and I’m having a specific problem with the video streams.</font></div><p style="margin: 0px;" class=""><font face="Calibri" size="3" class=""> </font></p><div style="margin: 0px;" class=""><font face="Calibri" size="3" class="">Basically, I am using conference mode pass through and it’s working great unless one of the attendees is vmuted.

They didn’t seem to do anything, so I just want to make sure I am not missing something. Ideally the video of the last person sharing video will continue to show in the canvas while the user who is vmuted speaks. Is there any way to achieve this? Any help would be much appreciated, I’ve hunted through the mailing lists and couldn’t find anything that addresses this specific challenge.</font></div></div></div></blockquote><div><br class=""></div>Features like this require mux mode</div><div><br class=""><blockquote type="cite" class=""><div class=""><div style="font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; background-color: transparent;" class=""><p style="margin: 0px;" class=""><font face="Calibri" size="3" class=""> </font></p><div style="margin: 0px;" class=""><font face="Calibri" size="3" class="">Thanks in advance for your help.</font></div></div></div></blockquote></div><br class=""></div></div><div class=""><br class=""></div><div class="">Mike</div></body></html>
