Missing V4L2_PIX_FMT_JPGL

Missing V4L2_PIX_FMT_JPGL

[Hans Verkuil]

Hi Hans,

I just copied the latest videobuf2.h to v4l-utils and tried to compile,
but it fails with:

make[2]: Entering directory
`/home/hve/work/src/v4l/v4l-utils/lib/libv4lconvert'
cc -Wp,-MMD,"libv4lconvert.d",-MQ,"libv4lconvert.o",-MP -c -I../include
-fvisibility=hidden -fPIC -DLIBDIR=\"/usr/local/lib\"
-DLIBSUBDIR=\"libv4l\" -I../../include -I../../lib/include -D_GNU_SOURCE
-DV4L_UTILS_VERSION='"0.8.4-test"' -g -O1 -Wall -Wpointer-arith
-Wstrict-prototypes -Wmissing-prototypes -o libv4lconvert.o
libv4lconvert.c
libv4lconvert.c:73: error: 'V4L2_PIX_FMT_JPGL' undeclared here (not in a
function)

It seems V4L2_PIX_FMT_JPGL was removed. I guess the support for this
format can be removed from libv4lconvert.c?

Regards,

       Hans

Actually it is not removed, it is not yet added. This is a new format
for devices using the (ancient) nw80x chipset. Jean Francois Moine has
been working on adding support for those to the gspca driver. I expect
a pull request from him soon, to add this driver to 2.6.39, and thus
the define to videodev2.h . In the mean time please leave the define
in v4l-utils's videodev2.h copy (insert it manually after syncing).

Regards,

Hans
