This last test seems to behave as it should. I agree, the bytes reads
seem rather high. What does the captured mpeg look like? Is it OK or
corrupted? What is the CPU load during capturing?
As an comparison: this is what I get with the beta:
Opened output "test.mpeg"
Opened input "/dev/video2"
ioctl IVTV_IOC_S_GOP_END ok
IVTV_IOC_S_GOP_END 1
0, Running, bytes_read=131072, bytes_written=131072
1, Running, bytes_read=8128, bytes_written=8128
2, Running, bytes_read=59392, bytes_written=59392

ioctl VIDIOC_STREAMOFF ok
VIDIOC_STREAMOFF set
40, Off, bytes_read=102464, bytes_written=102464
finished
