I think I found the reason (but not really an explanation):
If I don`t use the following code -which works in 0.8- , the plugins works:
bool cPvrDevice::SetVideoNorm(int norm)
{
v4l2_std_id std=V4L2_STD_PAL;
switch (norm)
{
case videoNormPAL:
std = V4L2_STD_PAL;
break;
case videoNormNTSC:
std = V4L2_STD_NTSC;
break;
case videoNormSECAM:
std = V4L2_STD_SECAM;
break;
}
if (IOCTL(video_fd, VIDIOC_S_STD, &std) != 0)
{
log(0, "VIDIOC_S_STD failed, %d:%s", errno, strerror(errno));
return false;
}
lastNorm=norm;
return true;
}
Now I commented out every call to SetVideoNorm. But why does it work in 0.8 and
not in trunk? At least with trunk the plugin works in PAL without setting the
norm in the plugin (uses driver default?)

no, that works.
A similar problem existed with earlier ck-versions, when IVTV_DMA_DEC_BUF_SIZE
was reduced from 0x00020000 to 0x00008000.
The plugin uses a ringbuffer; I tried to reduce or increase its size, but it
doesn`t help.
If you want to have a look in the source code:

I attach the log.
