Michael Niedermayer 99683a3077 2 byte shorter userdata for mpeg4
in the past it was startcode,string,00,7F,startcode
now it is startcode,string,stratcode
both are mpeg4 compliant, as according to the standard the userdata lasts until the next 00 00 01 (startcode prefix) but some very primitive decoders which simply skip until the first 00 byte and then expect the next valid startcode might fail with the old variant, just a theory though (didnt test if quicktime can decode it now)

Michael Niedermayer 65a24d0b39 optimization & bugfix extracted from the 4k line diff between ffmpeg 0.4.7 and http://www.alicestreet.com/ffh263.html
the other parts of the diff where
1. spelling fixes (rejected as only a small part of it could be applied automatically)
2. cosmetics (reindention, function reordering, var renaming, ...) with bugs (rejected)
3. rtp related stuff (rejetced as it breaks several codecs)
4. some changes to the intra/inter decission & scene change detection (quality tests needed first)

Michael Niedermayer 158c7f059c use lagrange multipler instead of qp for ratecontrol, this may break some things, tell me ASAP if u notice anything broken
quality which was 1..31 float is now a 1..FF_LAMBDA_MAX int, and FF_QP2LAMBDA * qp can be used to convert to the new range
