Too bad.
I also have a device (HP Jornada 710) that only have OSS sound driver..
We have to keep V4L1 for sure, at least for some time.
The good is thing is that any option we have does respect the presence of a
V4L1
driver.

With your patch: What happens if someone has kernel >= 2.6.38 and does
NOT LD_PRELOAD libv4l1compat.so? Does cinelerra still run, and only some
drivers do
Hi Hannes,
In this case, cinelerra will work as always.
If one try to use any V4L1 feature without LD_PRELOAD'ing the
libv4l1compat.so, when the V4L1 cinelerra code calls an V4L1 ioctl(), it
will fail.

People,
Thinking a little, after Einar email, I reached a patch that:
- keeps v4l support as always for people using kernel <= 2.6.37
- keeps v4l support for people using kernel >= 2.6.38, needs
LD_PRELOAD'ing of libv4l1compat.so
- cinelerra compiles fine with and without libv4l
- adds videodev.h
Hi Einar,
I must disagree with you.
If you take a look at the old videodev.h, there is this statement:
* Video for Linux version 1 - OBSOLETE
*
* Header file for v4l1 drivers and applications, for
* Linux kernels 2.2.x or 2.4.x.
*
* Provides header for legacy drivers and
Hi.
You must not unconditionally remove v4l1 support. I think that
configure must detect v4l1 and if it does not exist use libv4l1. There
may be some older devices, that have only v4l1 drivers. We have to
leave user an option to use older kernel with v4l1 support. Option to
fully remove v4l1 would
Also, we should add to the manual that if one is using kernel >= 2.6.38
and the operating system does not LD_PRELOAD the libv4l1compat.so, and the
use of the V4L driver is needed, you should do this before open cinelerra:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
Best regards,

Attached is a patch that at least verify the presence of the libv4l header.
We could #ifdef the v4l code in order to allow the compilation without
libv4l.
