   Audio and Video decoding library Version 53.611

This is a  Native Shared Library  for AmigaOS4  to decode
audio and video streams,  it is  based on the well  known
FFmpeg's libavcodec library.

This version is based on  FFmpeg 0.10.3 "Freedom"   which
was  released  on  2012-05-06.  It is  the latest  stable
FFmpeg release from the 0.10 release branch,which was cut
from master on 2012-01-26. Amongst lots of other changes,
it includes all changes from ffmpeg-mt, libav  master  of
2012-01-26, libav 0.8.2 as of 2012-05-06.

Unlike previous versions, 53.x+ does  *not*  requires nor
uses external codecs as these available from libs:avcodec
basically  because  everything is  build-in.  You'll find
three libraries on the archive, altivec, non-altivec, and
debug builds. Please use the debug one to report bugs.

Such DEBUG version will open  a CON  window  where  it'll
print its messages,  if you are a FFplay/FFmpeg  user you
should be familiar with them. You can control the  amount
of messages by the use of an environment variable.

shell> setenv AVCODEC_LOGLEVEL 16

Possible values are:

- AV_LOG_QUIET    -8
 \ No debug messages at all.

- AV_LOG_PANIC     0
 \ Something went really wrong and we will crash now.

- AV_LOG_FATAL     8
 \ Something went wrong and recovery is not possible.

- AV_LOG_ERROR    16
 \ Something went wrong and can't losslessly be recovered

 \ Something somehow does not look correct.

- AV_LOG_INFO     32
 \ Include informational messages.

 \ Verbose messages printing.

- AV_LOG_DEBUG    48
 \ Stuff which is only useful for libav* developers.

Other environment variables available are:

- AVCODEC_TRICKS: When enabled certain tricks are used
  which may or may not causes a noticeable speed up,
  depends on the system and/or codec...

- AVCODEC_LOWRES: Same as the FFmpeg option.
  (ie, setting it to 1 halves the size of the video)
