hello,
i'm using ivtv 0.3.3x (latest release) with a 2.6.11 kernel on my
debian/unstable amd64 box, and i got it running the way that mythtv
shows tv streams.
anyhow the streams are rather fractured and broken, sometimes i get a
clean tv stream for some seconds, but at least every minute it breaks,
and therefore is not really usable.
on my console i get thousands of these messages:
ivtv: ENC Stream 2 OVERFLOW #70: Stealing a Buffer, 8388770 currently allocated
ivtv: ENC Stream 2 OVERFLOW #71: Stealing a Buffer, 8388770 currently allocated
ivtv: ENC Stream 2 OVERFLOW #72: Stealing a Buffer, 8388770 currently allocated
ivtv: ENC Stream 2 OVERFLOW #73: Stealing a Buffer, 8388770 currently allocated
my modprobe.d/ivtv contains:
---SNIP---
alias char-major-81 videodev
alias char-major-81-0 ivtv
options ivtv ivtv_std=2 tda9887=0 ivtv_debug=1 tuner=38
options msp3400 once=1 simple=1 standard=0x03
options tuner pal=1
install ivtv /sbin/modprobe tuner; /sbin/modprobe msp3400; \
/sbin/modprobe saa7115; /sbin/modprobe saa7127; \
/sbin/modprobe --ignore-install ivtv; \
/usr/local/bin/ivtvctl -d /dev/video0 -u 0x3000; \
/usr/local/bin/ivtvctl -d /dev/video0 -u 0xff; \
/usr/local/bin/ivtvctl -p 4; \
/usr/local/bin/ivtvctl -f width=720,height=576;
---/SNIP---
do you have any suggestions where to start debugging?
my system is an amd athlon64 cpu on a VIA chipset:
