Installation de SDL
[root@sony waterworks-0.2.0]# urpmi sdl
Les paquetages suivants contiennent sdl :
libSDL1.2
libSDL_gfx11
libSDL_image1.2
libSDL_mixer1.2
libSDL_net1.2
libSDL_ttf2.0
perl-SDL
Après avoir remis à jour les médias (urpmi addmedia)
on obtient:
SDLcam

Est-ce correct ? (O/n) o
et cela donne un joli paquet de librairies installées...
mais cela ne fonctionne toujours pas.
Comme je suis du genre têtu, j'utilise la fonction v4l-info pour savoir ce que v4l a dans le ventre:
[root@sony bin]# v4l-info
# video4linux device info [/dev/video0] #
general info
channels
tuner
ioctl VIDIOCGTUNER: Invalid argument
audio
ioctl VIDIOCGAUDIO: Invalid argument
picture
buffer
window
Je trouve cela étrange car en lieu et place de video il marque vidio...
Ceci dit tout laisse à penser que WaterWorks fonctionne pour une entrée vidéo, mais pas pour une entrée webcam.
Dans ce cas cela pose pas mal de pb.
Par ailleurs tout laisse à penser également qu'il s'agit de caméra analogique et non pas de caméra DV.
Cela signifierait qu'il peut récupérer un flux d'un carte vidéo tuner, cam analogique et puis c'est tout...

515 = ENOIOCTLCMD

Actually, from
/usr/src/linux-2.4.29/include/linux/errno.h:
>>>>
/* Should never be seen by user programs */
...
#define ENOIOCTLCMD 515 /* No ioctl command */
<<<<
So that if the user programs displays error 515,
it might actually be a bug. But all other camera drivers
return also ENOIOCTLCMD for unknown ioctl, and qc-usb
does the same.

If it really annoys you, try editing qc-driver.c
line 2950 and change

retval = -ENOIOCTLCMD;

to e.g.

retval = -EINVAL;
