Hi, there! I have a big problem when capture video stream via four chips???
Now, I have four saa7134 chips to capture video stream at the same time in a process. After capturing video stream and almost using up the cpu resource to image processing for a long time, I met a problem that one of my chip will hang forever. Hang forever means that I will get the black display on my screen. After that, I try to unload/reload saa7134 driver and then restart my ap, the hang-chip still can't work. I also run xawtv with the hang-chip and I got the error message as follows: ioctl:
VIDIOC_DQBUF(index=0;type=VIDEO_CAPTURE;bytesused=0;flags=0x0[];field=ANY;;timecode.type=0;timecode.flags=0;timecode.frames=0;timecode.seconds=0;timecode.minutes=0;timecode.hours=0;timecode.
userbits="";sequence=0;memory=unknown): Input/output error capturing image
failed
What's wrong with my chip? Can anybody help me? Appreciate for your
help! Thanks.
