    Hi There,
    May be off topic for this forum but I didn't see another one that was more relevant and this is one of the busier ones.
    Does anyone know where I go to get some really in depth info on streaming video in general and more specifically, how best to get good quality from low bitrates?
    Thanks, iwb.

    xvid is supposed to be pretty good at low bitrates.

    But for better info on all codecs, read up at www.doom9.org. Ther should be some good stuff in the forums.

    I Do a search from protocols such a RSVP, SIP, RTP, RSTP and H323. These are some of the protocols and standards used to offer Quality of Service in a UDP or TCP network. Quality of Service is one of the big factors to consider when streaming audio or video over the net and I would imagine they would be the biggest consideration when bandwidth is very limited...

    I done a quick search and found this, seems ok

    If using Xvid consider a container like Matroska or OGM , the default container AVI is awful for streaming (awful for a lot of things for that matter).

    For XviD it doesn't matter what container you use, that should make no difference anyway because it's an MPEG 4 standard codec. The container really makes the difference when it comes to audio, the best audio compression at low bitrates is vorbis, but it doesn't attach to AVIs so you need to use an OGM or Matroska container for it. With the increased efficiency you gain from the smaller container format and the smaller audio file you can increase the quality of the video.

    Thanks for all the replies. The info was helpful and is sort of what I was looking for. What I would really like though is someone who has really indepth knowledge about H.264 and MPEG4 in general. Maybe even someone who can be hired to help out with a project I am working on at the moment.
    I have lots of questions and need to get results fairly quickly. The more I learn about this area, the more I realise how much there is to know. It isn't a trivial undertaking.
