</div><div><div></div><div><p class="MsoNormal"> </p><p class="MsoNormal" style="margin-bottom: 12pt;">Hey guys,<br><br>at the moment we want to configure our two AVT Marlin F046C cams in SSL Vision, so that we can use them with the highest framerate possible.<br>
<br>Unfortunatelly we're experiencing a lot of problems letting SSL Vision run with these two cams.<br><br>Our settings:<br>- OS: Debian 6.0<br>- SSL-Vision mode: YUV422<br>- One Delock Express Card - 34 Firewire card (notebook) / One WinTech Controller Card (VIA 6306 Chipset) (desktop pc)<br>
<br>The SSL-Vision errors we've got:<br>1. The unpatched version of SSL Vision is running with one cam only (max 25 frames). If we want to start the second one, we will get the error: Could not allocate ISO channel (should be a known issue)<br>
2. With a patched version (divide the bandwidth by two) of SSL Vision our two cams are working with only max. 18 frames each.<br><br>Do you have any experience with these kind of problems or can you answer these questions, please:<br>
<br>- What kind of Linux/libdc1394 do you use?<br>- Which SSL-Vision settings (Raw8, YUV422, ...) do you use?<br>- What kind of firewire card do you use and how many cams per card (one or two)?<br>- Do you have any clues to get SSL Vision running successfully?<br>
