Greetings from a newbie.
I've got a problem getting the DC30plus card to work. I compiled and installed the zoran drivers from the mjpegtools downloads page. That _seems_ to work so far.
Problems:
1) I can use xawtv to display the picture, but it tends to skip a lot. Almost like the card is skipping interrupts - except that it sometimes gets stuck for 30+ seconds at a time. I've tried two different slots to remove this issue, and it didn't seem to make much difference. I'll try the other two slots later and see if that fixes the problem.
2) When using mplayer to view the live stream, using: mplayer -tv driver=v4l:device=/dev/video0:input=0 tv:// I get this error: ioctl set picture failed: Invalid argument
3) xawtv capture also doesn't seem to work. It, too, complains about an invalid ioctl when trying to capture, but not when trying to view the live stream.
4) lavrec seems to be capturing a MJPEG stream, but there encoded stream seems to be corrupted. It is all blue, and at full PAL resolution, the video stream seems garbled, as if it is being displayed in strips that should be below each other, but have been misaligned, as if the sync signal was wrong. At lower resolutions (either set using the geometry option or the decimation option), the stream doesn't seem to be garbled, but instead seems to be cropped (rather than scaled) to the top left corner of the stream.
I am not sure if this is a decoder problem, because I can only play it back using "mplayer -vo x11". Not sure what the default output is (SDL?), but my graphics card seems to have problems with it - the display window is just blank blue.
I _THINK_ that the zoran/DC30 driver seems to be broken in some way, because I can use all the same software without any spurious ioctl problems using my cheapo bt848 based card, and that works perfectly (apart from the fact that the frame rates are quite poor without hardware compression).
Does anybody have any insights into what might be going wrong?
Here is a sample of the sort of messages what accumulates in the message log:
DC30plus[0]: zoran_open(X, pid=[2155]), users(-)=0
DC30plus[0]: UNKNOWN ioctl cmd: 0x800476c6
DC30plus[0]: VIDIOCSPICT - Invalid palette 9
DC30plus[0]: UNKNOWN ioctl cmd: 0x80287610
DC30plus[0]: zoran_close(X, pid=[2155])
DC30plus[0]: zoran_open(mplayer, pid=[2398]), users(-)=0 DC30plus[0]: UNKNOWN ioctl cmd: 0x80685600 DC30plus[0]: VIDIOCSPICT - Invalid palette 15 DC30plus[0]: zoran_close(mplayer, pid=[2398])
The machine in question is a RedHat9 box with a clean 2.4.29 kernel.
I am not sure what diagnostic information would be useful here, so I'm going to avoid posting the output of /proc/pci, lsmod, etc.
Many thanks.
