Hello,
I read about ieee1394 support in gem's pix_video, I immediately tried it out since my bttv died today. I used the example video patch in the helpfiles, I told it to use driver 1, it did say I had v4l AND ieee1394; I did a search on the mailinlist archive, but nothing came up like the problem I encountered:
fglX11AllocateManagedSurface: __FGLTexMgrCreateObject failed!! FGLTexMgr: open of shared memory object failed (Function not implemented) __FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!! fglX11AllocateManagedSurface: __FGLTexMgrCreateObject failed!! shutting down dv1394 after 140 usec
I note that suspicious three letter combo fgl there: and yes I have a radeon - is this the problem and is my video setup correct? I can view camera image with kino...
other question: afaik, dv cams use compressed video; I see cpu usage of kino is very high when only displaying frames - does this mean the video is being read from the camera and decompressed on the fly? does the dv1394 implementation on GEM work the same ( decompressing) and can I expect the same amount of cpu usage? using the bttv I know it's cpu friendly, but dv cam until now was cpu expensive.
