VPFE Capture driver for DaVinci Media SOCs :- DM355 and DM6446
is this the same set of patches present in the branch staging/vpfe ?
I'm having a doubt with that set of patches. Particularly, I'm having
problems when detecting the video format, because I don't find the
define VPFE_STD_AUTO any more.
My code is
std = VPFE_STD_AUTO;
if (ioctl (worker_acquire->fd, VIDIOC_S_STD, &std) == -1)
{
fprintf (stderr, "set_data_format: ioctl VIDIOC_S_STD failed\n");
return -1;
}
/* wait until decoder is fully locked */
sleep (1);
if (ioctl (worker_acquire->fd, VIDIOC_QUERYSTD, &std) == -1)
{
fprintf (stderr, "set_data_format: ioctl VIDIOC_QUERYSTD failed\n");
return -1;
}
if (std == V4L2_STD_NTSC)
{
fprintf (stdout, "NTSC camera detected\n");
}
else if (std == V4L2_STD_PAL)
{
fprintf (stdout, "PAL camera detected\n");
}
else
{
fprintf (stdout, "Unknown video input standard\n");
return -1;
}
But VPFE_STD_AUTO does not exist:
otta...@debian2:~$ grep -r VPFE_STD_AUTO
/home/ottavio/Projects/stuff/openembedded/tmp/work/dm6446-evm-angstrom-linux-gnueabi/linux-davinci-2.6.29+2.6.30-rc7-r8+gitr03022e38318bef016836dae71c70b9ea975723e7-r8/git/*
otta...@debian2:~$
So the question is: how do I autodetect the video format? Do you have
some reference code?
Thank you,
Ottavio
