Hello again, I come to ask for help again, because I am getting desperate. 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. It is a simple construction of two pix_video -> texture -> 3Dobject. And they seem not to be able to stream at the same time. 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. All opengl, glew and direct rendering is there and working. And it should be working for sure: http://vimeo.com/20685278 What can I be doing wrong? Has anyone a suggestion in which corner to look or how to trace the problem?
I know I should hit my self in the head for not making a backup of my working binary's and will next time.
