Hi there,
I'm using the bttv driver version 0.7.91 with a 2.4.18 kernel. I compiled the bttv driver separately from the kernel using http://bytesex.org/bttv/ and apply the patch "pending/bttv-0.7.72.subcap.patch" found in the tar.gz with minor corrections. I try to use temporal decimation (ie, I only want 3 frames out of 25 transfered on the PCI bus) since I have dozen of bttv based PCI cards and grabbing 25 frames per second at 640x480 is too much for the PCI bus bandwidth. So, using v4l API and the temporal decimation patch, I start grabbing. However, the ouput images are either black, or with a missing fields (only odd or even lines contains an image). Moreover, the v4l API returns the same image several time!!! I'd like to know if some other people out there have succeeded in using temporal decimation and HOW :-). I already read the bttv driver source code (which is not totally clear to me) and the bt788 datasheet (pdf). Thanks in advance.
