New header file: filters/{mirror,rotate}.h
- (Linux) mencoder, update snapshot to r27474
Additional differences may be obtained from the MPlayer
changelog/subversion logs (svn://svn.mplayerhq.hu/mplayer/trunk), aside
from overall stability and decoder/demuxer updates, notably addresses/adds:
o Nellymoser, Musepack SV8 audio decode
- new patches:
o ad_faad-restrict_aac_probe_adts.diff: restrict data probe prior to
libfaad init allowing additional AAC streams to successfully decode
o demux_lavf_02_remove_mov_preferred.diff: set legacy 3GP/3G2/MP4/MOV
demuxer (libmpdemux) to default for backward compatibility until lavf
demuxer’s performance can be assessed
o reduce_spurious_logging.diff: combine vo_fonts_warn_msg_level.diff &
vd_incompatible_vo_warn_msg_level.diff, add ffmpeg logging initialization
to mencoder.c
o mplayer_demux_real.patch: addresses security advisories
oCERT-2008-013 / CVE-2008-3827, the potential for heap overflow
within the real demuxer.

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3827
- updated patches:
o mencoder_03_joint_av_eof.diff: combine
mencoder_03_audio_eof.diff/mencoder_09_joint_audio_video_eof.diff
o mencoder_06_asf_pts_passing.diff, mencoder_07_demux_update_pts.diff,
mencoder_08_decoded_before_dups.diff, mov_08_tkhd_matrix_scale.diff,
mov_09_increase_sample_pts_size.diff: rename based on patch reduction
o mov-ignore_reference_trak.diff: ignore tracks that reference external
files, avoiding potential decode errors caused by non-existent data
- removed patches:
o flv_02_r12184_LE_codec.diff, flv_handle_bad_header.diff,
mencoder_06_conf.diff, mov_07_missing_stsd.diff: rendered unnecessary
Bug Fixes:
- FE2_FILTER_CROP, do not require both right and bottom to be set, consistent
w/documentation.
- FE2_FILTER_FRAMERATE/FE2_FILTER_PNGEX, fix bug causing duration to be
applied to incorrect frame resulting in incorrect transitions. seen esp.
w/text frames.
- (Linux) mencoder-muxer_ogg.c, discard frames w/neg. timestamps. allows
transcoding of certain WMV files to mov,mp4,etc., though in some cases
sync issues may still remain.
- (Linux) mencoder-muxer_ogg.c, treat 0 byte audio frame as indication of eos
avoiding transcode failure due to ErrFileIO w/certain clips.
NOTE: in some cases this is caused by multi-trak audio (MOV), the trailing
audio will be missing as this is currently unsupported.
- (Linux) FE2_CODEC_VP6, fix chroma problem caused by input w/an odd width
- (Windows) flvsplit.dll (v1.6.2.0) expose FFDShow compatible Nellymoser
output pin allowing audio to be transcoded

Features:
- FE2_MUXER_3GP/FE2_MUXER_3G2/FE2_MUXER_MOV/FE2_MUXER_MP4, add
FE2_ISOMEDIA_FASTSTART parameter allowing ’moov’ box placement to be
influenced, enabling progressive download.
- FE2_MUXER_FLV, add support for FE2_CODEC_AAC/FE2_CODEC_AACPLUS.
See API documentation for limitations.
Bug Fixes:
- FE2_MUXER_3GP/FE2_MUXER_3G2/FE2_MUXER_MOV/FE2_MUXER_MP4, avoid using fixed
framerate as video timebase. avoids failure should observed disagree
w/reported, esp. w/variable framerate input.
- FE2_CODEC_H263/FE2_CODEC_H263_BASELINE, should configuration of 2nd pass
fail attempt a single pass avoiding outright encode failure.
- FE2_FILTER_OVERLAY, fix crash when using gray scale PNG w/bit depth < 8
- (Linux) mencoder,
