Hi,
I got (very) basic MJPEG capture/display running with the DC1(plus)
and released it in the new version 0.5.0.
It works with PAL, 384x288 pixel, 25fps (more is not possible ;-))
Get it at: http://www.net4you.net/users/scherr/dc1plus/
Next step is writing some tools for it, as it still creates unusable
'raw' files containing the streams.
I just consider using the same ioctl's as the Buz/DC10 to support
lavrec/lavplay... Some other suggestions???????
Then there is also the open NTSC/SECAM support, but I'm missing some
test-sources....
Bye,
Wolfgang
The INSTALL file:
---------------------------------------------------------------------------
* THIS DRIVER NEEDS A KERNEL >= 2.2.x WITH INSTALLED VIDEO4LINUX
INTERFACE.
* I used 2.2.15 for developing/testing.
* compile this driver by simple starting 'make' in this directory
* Check if the wrapper program './up' is owned by 'root:root' and has
a set SUID bit
* run './up' to load the driver (as user)
* test it with xawtv (I used v2.46)
* a simple test program for streaming is ./jpeg_test - it does
following:
- loads the driver
- does a uncompressed 5-picture grab
- plays the uncompressed grab
- does a compressed 50-picture grab (75%)
- plays the compressed grab
- loads the driver again
* after grabbing a MJPEG stream you should reload the driver as it has
still
some open bugs (e.g. xawtv crashes after a compressed grab...)
* switching between compressed and uncompressed mode is done via the
proc interface:
- 'cat /proc/dc1_compression' switches compression ON (75%)
- 'cat /proc/dc1_plain' switches compression OFF
* additional info is in the source of the driver (dc1plus.c)
