Hi. I have a problem with cinelerra (hvirtual-1.0.0) video capture module. Starting it I obtain: VDeviceV4l::capture_frame:VIDIOC_DQBUF:Invalid argument VDeviceV4l::wait_v4l2_frame:VIDIOC_DQBUF:Invalid argument Enviroment: linux-2.4.19, FlyVideo2000, saa7134-0.1.10, gcc-3.2, libstdc++-v3 Questions: 1) Is that caused by incompatibility of stuff and drivers (videdev, saa7134)? 2) After patching 2.4.19-pre4 kernel I could compile videodev and v4l1-common v4l1-compat modules. There is in 2.4.19 only videodev. I suppose it solves all sybols from older v4l1-common v4l1-compat modules? 3) To compile hvirtual I had to libtoolize and reconfigure some submodules (a52codec in quicktime for example) Can it be causee of problem? 4) Does anybody know which version of avifile can I embed to hvirtual? I tried 0.7.15 - wrong. 5) What to do? In advane et cetera. Wieslaw
