Hi, I'm back at work and I can give you the details. The first problem I had was at compile time. I think it was linked with conflicting definitions. Here is the error message.
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< /bin/mkdir -p bc/gl perl ./gengl/gengl.perl --mode=alias "/usr/include/GL/gl.h" "/usr/include/GL/glx.h" "/usr/include/GL/glext.h" "/usr/include/GL/glxext.h" > bc/gl/alias.bc glFramebufferTextureLayerEXT is defined in both GL_NV_geometry_program4 and GL_EXT_texture_array at ./gengl/gengl.perl line 436, <H> line 10154. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< To solve it I did something quite ugly : I commented the mentioned line 436 of gengl/gengl.perl. After that It compiles but I looking forward a better fix. The second problem I get is the more important. The bugle filterset associated with screen capture is not recognised. I get the following warning : >>> warning: ignoring unknown filter-set screenshot BTW, Im using the following command : >>> BUGLE_CHAIN=video LD_PRELOAD=libbugle.so my_application with the following chain: <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< # Captures a video file. chain video { # Press C-V to start and to stop recording. By removing the "inactive" # tag, recording will start immediately. filterset screenshot C-V inactive { video "yes" filename "bugle.avi" # You can in theory use any codec supported by ffmpeg codec "mpeg4" # Roughly DVD size, although no high quality options are set bitrate "7500000" # By default, a frame is captured every 30th of a second, with # frames skipped or duplicated as necessary. Uncomment this # line to instead capture every frame exactly once to the # output. # allframes "yes" # Control the encoding latency. A higher latency may give # better throughput, at the expense of more memory. # lag "1" } } <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Just so you know, here is the recap of the configure script call (it may help): <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Configuration: libavcodec: yes readline: yes GUI: yes (with OpenGL) X event interception: yes <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Thanks very much.
