Hello again,<br><br>I come to ask for help again, because I am getting desperate.<br>I tried so many things, al version from 0.92.2 and up, and SVN build. I have tried compiling these with only gmerlin or quicktime or mpeg but all are not streaming 2 v4l devices at the same time. With or without sse2 or mmx does not seem to matter.<br>
It is a simple construction of two pix_video -> texture -> 3Dobject. And they seem not to be able to stream at the same time.<br>I am sure it is not the streams, cause I can run more then 3 streams and play all of them at the same time through the vloopback device with xawtv. Only within pure data they seem to switch on each other. Like a semaphore, just one at the time plays the others freeze.<br>
All opengl, glew and direct rendering is there and working.<br>And it should be working for sure: <a href="http://vimeo.com/20685278">http://vimeo.com/20685278</a><br>What can I be doing wrong?<br>Has anyone a suggestion in which corner to look or how to trace the problem?<br>
<br>I know I should hit my self in the head for not making a backup of my working binary's and will next time.<br><br>Regards,<br>Harrie<br><br><br><div class="gmail_quote">On Wed, Sep 14, 2011 at 12:59 PM, Harrie Hoogeveen <span dir="ltr"><<a href="mailto:harrie.hoogeveen@gmail.com">harrie.hoogeveen@gmail.com</a>></span> wrote:<br>

These 3 streams are mapped on 3D objects wich I contol using midi.<br>After updating to the latest Gem release this became very slow. They seem to play only one stream at the time.<br>
So fist object 1 plays for a sec or two, than stops and then object 2 starts playing for a sec or two, stops, an then object 3 and back to 1 again.<br>I tested with only one stream, this works fine, but as soon as I open 2, they start to switch in playtime again.<br>
I tried down grading to 0.92.3, which was the stable when I designed this patch, but the result is the same.<br>If I test the v4l stream with for example VLC the stream runs smooth.<br><br>I run pdextended 0.42.5 on a linux system with kernel 2.8.37 (after that vloopback is not supported anymore, cause it needs the v4l compat. support kernel option.)<br>
The video streams are generated with LiVES 1.4.4. It supports the vlooback output options. It is a UYV clamped stream, 280 pix wide:<br><pre>*** Using vloopback plugin for fs playback, agreed to use palette type 519 ( UYVY:Y'CbCr (clamped) ).</pre>
I run this patch on intel with 6 cores and nvida card.<br><br>What could be the cause that just one stream at the time plays in GEM?<br><br>Regards,<br><font color="#888888">Harrie<br>
