View Full Version : winamp/shoutcast or bandwidth problem
26th June 2004, 19:42
ok..broadcasting with shoutcast and nsvgui .6 or .7 ok
pre encoded video (30mb)
why does winamp buffer every 5 secs of play time on adsl 512k?
even on 1mb cable and adsl..it does the same
it isnt just my connection either..other viewers experience the same
on a 1 gig connection...its smooth as silk.
is there a setting somewhere to effectively cure this...
the shoutcast server and gui are both on a 4 gig connection?
ive searched around .....maybe ive overlooked the answer on here...

Because you are listing your downloads speed. When streaming you are uploading, so no matter how fast your download is, it is meaningless. A lot of DSL packages limit uploads speeds to 128kbps. Depending on how you encoded the video your bitrate can be MUCH higher then that. Therefore your connection would not be able to even handle one stream.
You can test your speeds here: http://speedtest.dslreports.com

so a solution mite be to re-encode the video????

If the video encode speed is higher than your upload speed, then that is the reason that your stream is buffering.
If this is the case then re-encoding to a slower bit rate would cure the problem.

Also, what frame rate are you using? Keep in mind that if you encoded at 30 fps. and usedn the default video quality settings, you are going to have HUGE problems as the video won't be ANYWHERE NEAR your upload bandwidth limit as it will be WAY WAY OVER that.
Try cranking it all the way to 10 fps. (that's 10.00 fps.), Also, if you're using VP6, try turning the video bitrate all the way down to 32 kbps. This is usually pretty good quality, though if you're using the old VP3, it will look kinda "primitive".
If you don't have VP6, you can download it from http://www.on2.com/
Also, what are you using for audio?? MP3? AAC? You will want to turn this down all the way to 64 Kbps. You will want to use MP3 as well (AAC just doesn't sound very good at this bitrate). It's also best if you use stereo, though mono will also work (but if you're going to do that, you may as well use AAC as that's better quality).
The end result should be somewhere in the neighborhood of 96 to 128K, which is DAMN GOOD for video. I'd also keep it at 320 x 240 or lower (Don't use the default 352 x 288 setting unless that somehow lowers the bitrate).
I'd also try encoding ONE OR TWO videos and play them back locally (as in WITHOUT SHOUTcast) first before encoding a whole batch of 'em. Save yourself some time and effort. :)
Beyond what I suggested you try, I'd have to say go back and re-read the stickies. :)
Hope this helps :)
Cheers for now :)

yeah..seems to have cracked it using the above suggestions.....
the only thing i'd like to know..and ive posted on kens forum..is ..'does the playlist work? on nsvgui.
ive added a cpl of movies to iot..... but it only ever seems to play 1...:o
soz if its in the worng place..but i would think that u have used this being the only interface around?

To use the playlist option in Kens GUI - you need to make sure that you encode all the movies at the same exact speed.
If you dont, you will get the error of just one video playing.

job well done....
