Hi,
On linux, you can use mencoder to grab audio + video and specify
any video input and output file and format you want to use. It is
much more easier to use than ffmpeg. Something like:
DSVID="/dev/video0"
NORM="PAL-BG"
SVID="2" # the input on the video device
ALSA_SVID="hw.1" # the ALSA card
RATE="48000" # [Hz] same than the sound card for best quality
WIDTH="634" # must be divisible by 16
HEIGHT="472" # must be divisible by 16
VRATE="4500" # [kbits] between 4 (small file) and 16000 (big file)
CROPED_WIDTH="628" # must be divisible by 16 or 4
CROPED_HEIGHT="448" # must be divisible by 16 or 4
CROPED_X="6"
CROPED_Y="16"
F_SV_REC="/home/dom/movie.avi"
mencoder tv:// -tv
driver=v4l2:device=$DSVID:norm=$NORM:input=$SVID:alsa:adevice=$ALSA_SVID:audiorate=$RATE:width=$WIDTH:height=$HEIGHT
-mc 0 -noskip -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=$VRATE -vf
crop=$CROPED_WIDTH:$CROPED_HEIGHT:$CROPED_X:$CROPED_Y,pp=lb -oac
mp3lame -lameopts cbr:br=64 -o $F_SV_REC"
For the video quality of VHS, if the player or the video camera
have a s-video output, and the video card a s-video input, the
final record will be better than with "standard" VHS quality.
Cheers,
Dominique
Interesting about Mencoder, but sorry - there is no S-Video IN port
on my video card
inxi -Fzx | grep Graphics
Graphics: Device-1: NVIDIA GK208B [GeForce GT 730] vendor: ASUSTeK
driver: nouveau v: kernel bus ID: 01:00.0
This is your video output port, not the input one.
Yes, the purpose was to show the name of the video card; NVIDIA GeForce
GT 730.
According to its specs it has 3 output ports: DVI, HDMI, VGA
I also verified that the video card, GeForce GTX 960, on my second
workstation (Supermicro) also has only output ports.
(In the past I had workstation(s) with analog I/O ports/ S-video, which
also was the case on the old video capture card Pinnacle DV500 for Windows).
