Streaming outside local network, question

[gEd]

On the client machine.....in VLC you can change the default buffer to something higher....I Think I have mine at 8 or 10 seconds instead of the default which I think is 1/2 second. This causes an initial delay of viewing of the steam but allows the buffer to fill and then when watching you don't usually end up getting the stop/go situation since there was an up-front buffer that is big enough to handle those issues.


I was just about to suggest this. I get stuttering of HD content at home if I only use default VLC buffer settings. I had to crank up my network buffer to 9000 to stop the stuttering and that is with a 270mb/s wifi connection.

1MB up is slow these days.... the quality you are seeing is because you are only at 128 bit rate...... if you can get that up to 512 or LAN you should see a big difference in the quality even with the ratio a .2.

I think I tried it, with no luck. But I'll try again tomorrow at work after having the buffer set to 10s (which you wrote about).

I'll try that. Only the networkbuffer? What does the 5s streamer buffer size in newa config do? I thought this would be the buffer (that I have to configure in vlc now).

Do I have to change the buffer on the server or on the client? At work (client) I can't install anything , so I'm using 1.1.11 portable and I can't find where to change the buffer.

I need to set scale to 0,20 to prevent buffering.
Changing bitrate does nothing. I have it set to 8K, but no difference!

we are talking about the buffer on the client, perhaps the portable version does not offer the option to change these settings, I have no idea.

What does the 5s streamer buffer size in newa config do?
I suspect that it simply provides a buffer between the transcoding process (serverside VLC) and the network port to help protect against delays in transcoding due to cpu / disk demands. I don't think it will help you here (mind, I have been wrong plenty of times before).

Changing the 5s buffer size in newa config to 10s does nothing here, so you might be wright.

Does changing the bitrate do anything for you? For me it doesn't. Even at 8k I see no difference at all.

Post your web.log file following the start of a video and I can take a look at what might be going on.

You are clicking update after setting to the 8k....correct?

[WKleeven]

I am clicking update after a setting, yes. EDIT: here are the logs.

Also compare values in VLC media info (CTRL-I during playback) and check codec info (to get info such as encoding format and resolution) and statistics tab (to get bitrate)

Absolutely, it does. At 128K, the VLC stats show 120-200K bitrate and the picture looks crap.

check your trancode options to ensure that they are the same as UJB's above.

you should see vcodec=h264
