ac66834c75 avcodec_decode_audio2()
difference to avcodec_decode_audio() is that the user can pass the allocated size of the output buffer to the decoder and the decoder can check if theres enough space

396a5e6837 store a few values in the header as difference to the last
this makes frames a few bytes smaller (0.1% for high bitrate but >1% for low bitrates)

2f16af0667 skip motion estimation and encoding of non direct-0,0 MBs if the next MB is skiped (mpeg4 doesnt allow such MBs and in the past we did ME and encoding until at the end we droped them, so this should be faster though i didnt benchmark it, benchmark welcome)

59743d16c7 dont randomly disallow intr4v in adaptive quant
some PSNR/bitrate gain if adaptive quant is used
initalize qscale_table correctly (it was pretty much random since the qp->lambda change)
  this probably has not much effect as the table isnt used currently IIRC
