Hi,
With recent git tree I'm still experiencing the same problem that
audio isn't captured with mencoder.
$ uname -a
Linux dancer64 2.6.15dancer-ga4fc7ab1-dirty #1 Thu Jan 12 08:32:49 JST 2006 x86_64 GNU/Linux
last successful one was 2.6.14-rc5.
I've noticed that there is a v4l-info command, which dumps v4l2
information, and it seems to signify that v4l2 is giving a different
answer.
The following is a diff, which seems to signify that this difference
exists in the two versions:
- audioset : 1
+ audioset : 0
What caused this change and how to revert is a mystery, yet.

Hi,
With 2.6.16-rc1, it's recording no audio, and it's recording
black-and-white noise on video. Wooo, it's getting worse.

>From the information that I've gathered so far it seems like:
1. bttv was rewritten to support v4l2
2. record via v4l2 is broken, v4l1 is not (xawtv works, mencoder broken.)
I've heard mencoder should work with v4l1, but I have not yet confirmed.
bttv-cards.c:
[BTTV_BOARD_GVBCTV5PCI] = {
.name = "IODATA GV-BCTV5/PCI",
.video_inputs = 3,
.audio_inputs = 1,
.tuner = 0,
.svhs = 2,
.gpiomask = 0x0f0f80,
.muxsel = {2, 3, 1, 0 },
.audiomux = {0x030000, 0x010000, 0, 0, 0x020000, 0},
.no_msp34xx = 1,
.pll = PLL_28,
.tuner_type = TUNER_PHILIPS_NTSC_M,
.tuner_addr = ADDR_UNSET,
.radio_addr = ADDR_UNSET,
.audio_hook = gvbctv5pci_audio,
.has_radio = 1,
},
dmesg gives me an impression that this path is taken properly:
bttv: driver version 0.9.16 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).

bttv0: PLL: 28636363 => 35468950 .. ok
v4l-info is dumped with:
printf("inputs\n");
for (i = 0;; i++) {
memset(&input,0,sizeof(input));
input.index = i;
if (-1 == ioctl(fd,VIDIOC_ENUMINPUT,&input))
break;
printf(" VIDIOC_ENUMINPUT(%d)\n",i);
print_struct(stdout,desc_v4l2_input,&input,"",tab);
}
printf("\n");
which is probably handled in
bttv-driver.c:static int bttv_common_ioctls(struct bttv *btv, unsigned int cmd, void *arg)
which unconditionally sets:
i->audioset = 0;

Hi,
status update, it's still like this; I probably don't have much time
to sit around debugging this problem myself, but if anyone else has
met this problem and fixed it, I'd be delighted to know about it.

Are you referring to bugzilla 5895 ? I just closed that ticket.

That sounds like a different module; I'm using 'bttv' module.
I've tried
rmmod bttv
rmmod tuner
rmmod compat_ioctl32
rmmod v4l2-common
rmmod tveeprom
rmmod videodev
rmmod ir-common
insmod v4l2-common.ko
insmod tveeprom.ko
insmod videodev.ko
insmod compat_ioctl32.ko
insmod tuner.ko
insmod ir-common.ko
insmod bttv.ko
on
$ hg log|head
changeset: 3295:02699cfc26d5
tag: tip
user: Manu Abraham <[email protected]>
date: Thu Feb 2 07:59:47 2006 +0400
summary: bugfix [5895], return an error value
and I can reproduce the situation.
The current situation being that no images come through mencoder,
which probably means it's not
1. tuning the tuner (If there has been a i2c breakage, sounds possible)
2. getting the images
or both.
I am able to see TV through xawtv, and I am assuming that means it's
working with v4l1 compatibility layer of some sort.
regards,
junichi
