- (linux,mencoder) allow mean framerate patch to only increase output
framerate. avoids artifacts when decoding certain h264 clips (mov, etc).
- (windows) update flvsplit.dll to v1.5.3.0, ignores flv header
information indicating presence of audio, manually inspecting the data,
allowing for audio extraction from malformed files.
- (windows) update qtsource.dll to v1.0.2.0, addresses incorrect framerate
calculation causing file to be transcoded at low framerate.
- (windows) forward base timestamp from the demuxer through the codec. allows
for material w/non-zero start times to remain in sync after transcode.
- (windows) fix color conversion bug producing green bar in videos
having an input width a non-multiple of 4.

Bug fixes:
- fix crash when removing unnecessary (i.e., desired==input)
FE2_FILTER_RESAMPLE
- fix encoder hang when specifying an explicit framerate > source with
FE2_FILTER_FRAMERATE
- (windows) fix bug causing loss of audio at input end. amt. varied based on
the clip w/as much as 8s loss possible.
- (linux) updated 64bit libflixengine2.so to allow for use on platforms whose
binutils and/or dynamic linker/loader do not have .gnu.hash
support, as evidenced by output similar to:
’/usr/local/lib64/libflixengine2.so: file not recognized: File
format not recognized’

Features:
- upgrade to lame-3.97
- add FE2_LAME_QUALITY parameter to FE2_CODEC_LAME
- added muxer interface
New API calls: Flix2_MuxerGetParam/AsStr, Flix2_MuxerSetParam/AsStr
Flix2_AddMuxer/Flix2_RemoveMuxer
New header files: muxer_constants.h, muxers/3gp.h,
muxers/flv.h, muxers/swf.h
NOTE: This update has deprecated many of the muxer related functions in
(swf|video)_options.h. Consult the deprecated list in the API
documentation as they will be removed in a future release.
- add FE2_MUXER_3GP. See the API documentation for limitations.
NOTE: Only available if this feature has been added to your license.
Contact [email protected] for further details.
- add FE2_CODEC_H263_BASELINE for use in conjunction with the 3gpp muxer.
- add FE2_CODEC_AMR_NB for use in conjunction with the 3gpp muxer.
- (windows) add ASP, ASP.NET and VB(6|.NET) samples
- (linux) add libtheora-1.0alpha7 (http://www.theora.org/) to mencoder build
- (linux) add support for FLIX_OGG_PHYMEM_PCTMAX environment variable used to
control individual ogg demuxer’s max memory usage to avoid a
segmentation fault due to unchecked memory allocations within
libogg. The default set in flixd’s start script is 70. See the
flixd man page for further details.
Bug fixes:
- modify FE2_FILTER_RESAMPLE to use FFmpeg based filter. addresses sync
issues when resampling longer content (esp. non-integer conversions, e.g.,
48->44.1kHz) as well as the issue of giving precedence to the left channel
when converting stereo to mono.
- fix bug causing audio and video to be improperly interleaved in certain
cases, mostly when dealing with clips that were variable framerate (wmv). a
video frame with a timestamp much greater than the current audio would be
inserted followed by a large amount of (earlier timestamped) audio causing
playback and FMS issues.
- fix bug in FE2_CODEC_LAME causing the frame prior to the final block to be
