8155233413 fixed layer1/2 overflow if very loud sound - fixed broken free format decoding to pass all mpeg audio standard decoding tests (please avoid patching the parser without having all test streams available - contact me if necessary)

31def22984 * Bad buffer management bug. Forgot to take care of the case
where doubling the size of the buffer is not enough.

fca0f0e59f * removed MANGLE from macros for setting constants
* using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
  as its always faster
* PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
* replaced original pixels_xy2_mmx with new faster and equal implementation
* replaced usage of mm7 for other then ZERO contstant in _rnd & _avg file with mm6

cde25790ec * New stuff and bug fixes:
* Change to dynamically allocated buffers. Should reduce memory footprint significantly
  as well as eliminate a call to av_abort!
* Better version of WMP rate switching infrastructure. Currently turned off till
  the PTS fixes are in.
* Added a Redirect type feature. This allows URLs served by ffserver to just
  redirect to somewhere else. You might want to do this. Really this needs to
  be enhanced -- say to handle all 404 pages.
* Add mechanism to automatically fire up ffmpeg on ffserver start. This is turned
  on by adding the Launch keyword to the <feed> definition.
* Add logic to take care of non-wmp user agents requesting .asf files. They now get
  a [reference] file with an appropriate mime type. This fixes the mplayer problem.
* Make sure that we have a large buffer for the stats page.
* Add a FaviconURL keyword to the status stream definition. If set, then it
  generates the appropriate HTML so that IE and Mozilla will display the favicon
  as appropriate. OK -- this is a pretty random feature.
* If the ffmpeg is running as a child of ffserver, then report it's CPU usage
  on the status page. [This is linux only -- maybe somebody could do the work for
  another OS. The tricky thing is getting the 'ps' command right.]

cb09b2ed92 * Go faster stripes: don't check to see if the user presses 'q' if stdin
returns EOF -- e.g. it is connected to /dev/null
* Make the 1MB video buffer only allocated once rather than on each frame.
  The allocation and deallocation causes significant performance loss as the
  kernel remaps the address space each time.

91abb473fb * code with new PAVGB for MMX only CPU splited into separate file
and being compiled in the same way as _avg.h
* PAVG_MMX macros accept also output parameter
* implemented faster put_pixels_xy2, but it has slightly smaller precission.
  But there is not visible difference in the image quality - might be eventualy
  easily switched back (#if 0 #endif)- please check

3120d2a265 * Add first cut of code to handle Windows Media Player rate switching
requests. The current state is that at startup, WMP will get the
  best stream that it can handle. However, subsequent rate switching
  only puts a message in the log saying what the new stream ought to
  be. Solving this will be tricky. I guess that we would have to wait for
  key frames to appear in the new stream, and then switch over to it.
  Some care would be needed to deal with the PTS of the new stream
  versus the old stream.
