[streaming] V4L test

[Ariel Fritz]

Hi

I have tested the CVS version of VLS  and it work well. I have tested 
with  a multi-input bttv card and with a tv tuner bttv card.
I have make unicast stream from the bttv card on our internal Lan but 
the received video is choppy. The vls is running on a Athlon 1.8 GHz 
with 512 Mb of  RAM. It has a 100 MBps ethernet lan card to stream video 
to the network.
 
I would like to know how to configure my vls.cfg file to make a good 
streaminig to the network. Please if you can explain to me the following 
fields of the vls.cfg file:


# Video For Linux (V4L) configuration
BEGIN "tuner"
# --- Example:
Device        = "/dev/video"     # Video4linux device (default is 
/dev/video)
Channel       = "1"              # Channel Source: Webcam often 0
                                 # For TV Card, may be Tuner(0), 
Composite(1),
                                 # Svideo(2)
# Frequency     = "7668"           # Frequency (Mhz) * 16
Norm          = "1"              # PAL=0, NTSC=1, SECAM=2
Size          = "VGA"               # Size possibilities

                                 # - empty string : default size
                                 # - width x height
                                 # - subQCIF(128x96), QSIF(160x120),
                                 #   QCIF(176x144), SIF(320x240),
                                 #   CIF(352x288), VGA (640x480)
DeInterlace   = "0"
Compression   = "mpeg2"             # mpeg1 or mpeg4 [experimental]
Bitrate       = "15000"            # Bitrate (approx.) in kbps
Quality       = "1.0"            # 1.0 (good) to 31.0 (bad)

#AudioDevice   = "/dev/dsp"       # Sound device (try /dev/dsp<X>
#AudioCompression = "mp2"         # mp2, mp3 or ogg
#AudioBitrate  = "64"             # Audio bitrate in kbps
#AudioFreq     = "16000"          # 16000, 22050, 24000, 32000, 44100, 48000
#AudioChannel  = "2"              # 1=mono, 2=stereo
END

and one more question: what are the hardware requirements to streaming 
video with a bttv card?

thanks a lot and regards
