7.1. Stream with the Hauppauge WinTV-PVR-250 card7.1.1. Install the drivers
First, you will have to patch your kernel to support
the v4l2 API (Video 4 Linux version 2). The patch is available on the
Video4Linux HQ
.
Once your kernel is ready, install the CVS version
of the Linux drivers for the Hauppauge WinTV-PVR-250. They are hosted on
ivtv.sourceforge.net.
Then, you will have to create the device and load the modules; for this,
please refer to the documentation shipped with the drivers
. 7.1.2. Stream with VLC |
You must add --enable-pvr
to ./configure to use this
feature. You may want to change the value of
CR_MAX_AVERAGE_COUNTER to 1000
in src/input/input_clock.c to work around a problem
with the card

% vlc -vvv pvr:/dev/video0:norm=secam:size=720x576:frequency=576250:
bitrate=3000000:maxbitrate=4000000 --sout udp:192.168.0.42 --ttl 12

where
: /dev/video0
is the device corresponding to the encoding card
, norm=secam
is name of the standard of the analogic signal
(possible values are pal, secam, and ntsc)
, size=720x576
is the size of the video you want to stream
, frequency=567250
is the frequency in kHz of the channel you want to
stream
, bitrate=3000000
is the average bitrate of the stream
, maxbitrate=4000000
is the maximum bitrate of the stream
, 192.168.0.42
is either
:
the IP address of the machine you want to unicast
to
;
or the DNS name the machine you want to unicast
to
;
or a multicast IP address
.
12
is the value of the TTL (Time To
Live) of your IP packets (which means that the stream will be
able to cross 11 routers)
.
7.1.3. Stream with VLS
There is no command line interface for this input
for the moment, so you will have to use the configuration file
.
You cannot set-up the parameters of the drivers
(norm, size, frequency, bitrate, etc...) with VLS: for that, you will
have to use the program ptune.pl that come with the
drivers. Please refer to the documentation shipped with the drivers to
learn how to use this program
.
Here is a typical configuration file
vls.cfgto run VLS with a Hauppauge WinTV-PVR-250
encoding card
:
# vls.cfg (VLS configuration file)
# Example of the VideoLAN HOWTO for the Hauppauge WinTV-PVR-250 encoding card
BEGIN "Inputs"
pvr = "video"
END
BEGIN "pvr"
# Hauppauge WinTV-PVR-250 device
Device = "/dev/video0"
# Stream type
Type = "Mpeg2-PS"
END
BEGIN "Channels"
channel1 = "network"
END
BEGIN "channel1"
# Unicast or multicast IP address
DstHost = "192.168.0.42"
# Destination port
DstPort = "1234"
# If it's a multicast IP address, uncomment the line below
#Type = "multicast"
# If it's a multicast IP address, set the "Time To Live" below
#TTL = "12"
END
BEGIN "LaunchOnStartUp"
command1 = "start video channel1 pvr"
END
|
Once you have adapted the configuration file above,
run VLS
