x264 live streaming parameter suggestions

As the title says, i'm streaming live h264 on a windows machine. The problem is the bitrate keeps skipping way beyond my network upload capabilities (typically <1mbps DSL upload). What parameters would you suggest to prevent this from happening while still maintaining best possible quality ? I know ...

Re: CBR mode in x264

I'm still trying to stream live h264 from a windows machine. I'm still puzzled by this bitrate management issue. Again, what parameters would you suggest ? I tried the suggested options to no effect. I know most modern codecs rely heavily on VBR for quality. Some developpers don't even want to hear ...

If it is not GPL compatible then i understand why this hasn't been done.
Hope someone will provide a workaround somehow.

Thanks.

CBR mode in x264

This is a very serious request. I know many people consider CBR as an outdated bitrate management method. However if the statistics panel is accurate (Ctrl-I), i can't get any stable bitrate when streaming live. I've tried averything i could think of. qcomp=O doesn't change anything for me. Setting ...

AAC+ encoding through 3GPP spec. sources

AAC+ sources are available as part of the 3GPP specifications.
http://www.3gpp.org/ftp/Specs/

So why can't AAC+ encoding be added to VLC ?

This guy already made a CLI encoder out of it, and i don't see anyone suing him for it.

Seriously Marius, the setting i mentioned above seems to have solved the problem. You actually HAVE to tell VLC to use two threads. I now have a cpu usage close to 100% and am able to stream live 640x480 H.264 at 25fps through my home LAN. I'm doing this with vlc beta 0.8.5. The 64X2 3800+ is curren...

to answear my own question : I was able to "force" my CPU usage to 83% and above by going to the parameters > preferences > Sout stream > transcode > (advanced options ticked) > number of threads : 2 However, wathever bitrate i used, video was still more or less jerky. Any ideas ?

Athlon 64X2 and h.264 encoding - performance pb

It was my belief that Videolan supported multithreading. I recently upgraded from an Athlon XP 2800+ to an Athlon 64 X2 3800+ Knowing that the latter had a similar processor speed per core compared to my old cpu, i only expexted an improvment in encoding performance through the use of the second cor...

Avisynth like output

I use VLC to receive live networked TV channels from my Internet service Provider. Since VLC doesn't support real video encoding, i'm looking for a way to send these Mpeg 2 transport streams in real time to realproducer, which unfortunatly only suports avi files as input. So i thought outputting the...

audio and video combinations for live streaming

Vorbis features are well documented here http://www.videolan.org/streaming/features.html However, i couldn't find any reference table as to which audio and video codecs combinations are possible. For exemple, is h.264 with Vorbis audio possible ? If so, which container ? Also, what are the color spa...
