Once you set the input to svideo, just use /dev/videoX (where X is your device number, starts with 0) to get the combined mpeg stream.

Subject: [ivtv-users] S-video; how to get audio?

Hello, we'd like to use the S-video input to get the best image quality
from the VHS player into the Hauppauge PVR-500MCE. Apparently we need
the RCA audio inputs as well, but I would appreciate some help in
understanding how to combine the S-video and audio into a usable file
using MythTV or any other software.

I'm not even sure what device is processing the audio stream; is
it /dev/video24?

Thanks.

If the PVR-500MCE is like the PVR-250 it has a 1/8" audio input jack. Use an
adapter to convert the player's RCA audio output to 1/8" and plug it into
the PVR card. Your captured video should include audio.
I hope this doesn't totally miss the question.

I have been trying for many days to capture analog video from a VCR using a
PVR-250 and any software I can find, on Linux or Windows. (VLC and mencoder
on Linux). The only thing that has worked so far is Hauppauge WinTV v6 on
Windows. Can't make anything work on Linux. Please post your results for
those of us struggling

Thanks,
Peter

$ v4l2-ctl --help

$ v4l2-ctl -d /dev/video0 --list-inputs
ioctl: VIDIOC_ENUMINPUT
Input : 0
Name : Tuner 1
Type : 0x00000001
Audioset: 0x00000007
Tuner : 0x00000000
Standard: 0x0000000000001000 ( NTSC )
Status : 0

Input : 1
Name : S-Video 1
Type : 0x00000002
Audioset: 0x00000007
Tuner : 0x00000000
Standard: 0x0000000000FFFFFF ( PAL NTSC SECAM )
Status : 0
[....]


$ v4l2-ctl -d /dev/video0 --set-input 1
Video input set to 1 (S-Video 1)

(That will also set the audio inputs to Line-In 1 audio.)


$ ivtv-tune -d /dev/video0 -t us-bcast -c 3
/dev/video0: 61.250 MHz

$ cat /dev/video0 > foo.mpg

(foo.mpg will be an MPEG-2 PS with video and audio multiplexed in.)



Instead of cat, you could have also done

$ mplayer /dev/video0

To decode and play the MPEG-2 encoded audio and video streams.

If you just want to hear the raw PCM audio samples being fed into the
CX23416 MPEG encoder you could do this

$ aplay -f dat < /dev/video24

Andy

Forget the ivtv-tune command, it isn't needed. I guess I'm a bit tired.

Wonderful, thank you; it works as desired with cat and mplayer. Now if I
could just get MythTV to recognize that video input all would be well,
but I suspect it's more of an operator issue. <g>

The PVR-500 thankfully doesn't have such a connection, as the RCA audio
inputs are more easily dealt with. I have a composite RCA cable from the
VHS player to the Hauppauge card and just unplug the yellow video and
use an s-video cable for input to the card, hence the nature of my
original question. Thank you Andy for the simple and elegant solution.

I've been using the ivtv software/firmware to capture the /dev/video[01]
output to hard disk on a Linux CentOS 5.4 machine, and am using
qdvdauthor to create the DVDs with menus etc. and am quite happy with
the results.

In order to assist with the start/stop of the recording and positioning
of the tape, I need to watch the video stream while it's being saved to
disk however, and couldn't figure out how to do that with either mplayer
or cat, so I am trying to use MythTV and am meeting with some some
success there using the composite video input, but have yet to
accomplish the s-video input.

MythTV not a trivial task for me to either understand or implement, and
your use of the term "struggling" is an understatement in my case. The
gui is incredibly non-intuitive, and even after many days of struggling
I still have difficulty navigating and understanding the structure,
which seems overly complicated for my very simple need of watching the
video stream at the same time as it's being recorded to disk.

If anyone has a better solution for watching the /dev/video[01] stream
while it's being saved to disk I would be very grateful to hear from
you, even though it's somewhat off-topic in the ivtv-users list.

cat /dev/video0 | tee <output file> | mplayer -

where <output file> is the file you want to record to. Seems to work ok w/ my
PVR-500.

Yes, thank you, of course that works, yet it has similar limitations as
MythTV, albeit without the complexities ... the recording doesn't start
until the video is visible and vice-wersa.

What I'd like is to be able to do is watch the video stream and start/stop
recording to disk whenever desired. That way I can avoid lengthy dead space
prior to the start of the actual video, and stop it whenever desired, sort
of a real-time stream extraction to disk.

If I use "mplayer /dev/video0" then I can see what's happening, but am then
unable to cat to a file when desired:

$ cat /dev/video0 > test.mpg
cat: /dev/video0: Device or resource busy

But the PVR-500 has two tuners, so I thought I'd try to use /dev/video1
after using the same video input as the /dev/video0:

$ v4l2-ctl -d /dev/video1 --set-input 1
Video input set to 1 (S-Video 1)

As reported in dmesg:

If you don't mind to use VLC instead of MPlayer, you can watch your
stream and record/dump it to disk whenever you want with a hotkey
combination (Shift+R for recording, Shift+D for dumping). I don't know
if the second time you record during a session the file will be
overwritten or a new file will be created instead, as on the computer
I'm currently working with there is no video grabber.

MythTV is always recording to disk when you start to watch TV. What you
see is MythTV is slightly delayed, as it's built up somewhat of a buffer
on disk.

$ mplayer /dev/video32 -demuxer rawvideo -rawvideo w=720:h=480:format=hm12:ntsc

will play the YUV (uncompressed video) stream. It is in advance of the
MPEG stream by about 2 seconds and is the actual video that the MPEG
encoder is about to compress and make available
on /dev/video0. /dev/video32 can be read from simultaneously
with /dev/video0. (The penalty is of course increased PCI bus usage,
and increased CPU to render video.)

Andy

It's exactly what was needed only far, far better, thank you. It's much
more functional than mplayer.

As long as the video stream from /dev/video? is continuous, toggling the
recording function with Shift-R first creates then appends the file, e.g.
$HOME/vlc-record-2009-11-20-04h23m44s-video0-.mpg

If the video stream is broken, such as stopping and starting the VHS
playback, then the next Shift-R creates a new file with the current
timestamp in the filename.
