saa7134 & cinelerra

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



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.
