Greetings,<br><br>After several days of programming work I can now present this first version of a new external for pdp that hosts FreeFrameGL1.5 plugins.<br>My first project using C++... slow learning!<br><br>The external does conversion from YUV to RGB and back using fragment shaders.  The real bottleneck is the glReadPixels call that copies texture information back to main memory.  I managed to implement it using asynchronous pixel buffer DMA, so it doesnt block.  Disadvantage is one must wait for the transfer to end (anyone know how I can check for this?) so I wait for the next frame to arrive before writing out the current frame to pdp, so input 1 frame, it outputs only when you input another...<br>
<br>Little testing has been done, and to my understanding there are not many FFGL plugins available (please proof me wrong here), still if anyone could give the external a spin that would be nice.  A test file is provided.<br>
<br>The external needs you to have the GL_EXT_gpu_shader4 extension available on your OpenGL system, like I can run it on nVidia here but not on Intel.  Any feedback on IF it works at all would be great.<br><br><br>Get the first tarball at: <a href="http://www.ewocprojects.be/pdp_ffgl.html">http://www.ewocprojects.be/pdp_ffgl.html</a><br>
<br><br>Also the visually inclined might check my Pd video mixer EWOCvj at <a href="http://www.ewocprojects.be">http://www.ewocprojects.be</a><br><br>Also I have some code that does video wiping for pdp, check this on the Pd forum.<br>
