7.4 CHANGELOG 361
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2445
- FE2_FILTER_PNGEX, should end-of-stream be encountered and not all requested
PNGs have been written (due to misreported duration) output 1 final PNG.
- FE2_FILTER_PNGEX, when using FE2_PNGEX_AUTO_EXPORT_COUNT and clip duration
cannot be determined output the first FE2_PNGEX_AUTO_EXPORT_COUNT
frame(s), as opposed to none at all.
- (linux) mencoder, add preliminary support for movie fragments contained in
file formats based on ISO-14496 Base File Format, most notably 3GPP2 (.3g2)
files. addresses clip truncation.
- (linux) mencoder, add patch (avi_forceidx_fallback.diff) forcing index
regeneration should the reported number of frames not match the number of
index entries. addresses various duration issues for this format.
- (linux) mencoder, update muxer_ogg to allow delayed stream setup. addresses
missing video in certain mpeg based streams when info is unavailable prior
to decode.
- (linux) remove scale=0:0 mencoder filter as prescaling interlaced material
results in output artifacts. FE2_FILTER_SCALE can now be used to achieve
similar results.
- (windows) fix color convert bug causing video encode to fail (ErrEncodeV)
should the source have an odd width.
- (windows) add decode timeout to avoid hung encode session due to corrupt
input file. most visibly addresses hangs caused by wmv decoders supplied
with windows media player 9/10, the latter being the release currently
available under win2k3. Flix2_Errno will be set to -2 in this case. this
change only adds a timeout for data production by DirectShow and will not
correct hangs related to destroying the decode graph (currently seen with
certain QuickTime files).
- (windows) FE2_FILTER_PNGEX, enable support for ’/’ delimited paths. fixes
incorrect PNG name generation resulting in misplacement or outright failure
should FE2_PNGEX_(OUTPUT_DIRECTORY|FILENAME_PREFIX) be left unset and the
output filename be ’/’ delimited.

2007-04-13 v8.0.8.2 Linux
2007-04-13 v8.0.8.2_DEMO Linux

2007-04-13 v8.0.8.2_DEMO Windows COM v0.0.2.0
Features:
- add optimized scaling code to FE2_FILTER_SCALE improving encode time 25-35%
depending on the input. greatest gains are seen when scaling large input to
comparatively smaller size, e.g., 720x480->256x192.
- (linux) updated mencoder snapshot to r22906.
A full list of differences can be obtained via the subversion logs
(svn://svn.mplayerhq.hu/mplayer/trunk), notably addresses:
o buffer overflow in DirectShow loader.

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1387
o artifacts when transcoding flvs w/height a non-multiple of 16
o framerate issues (>actual causing fast playback) w/certain input flvs
o inability to load drvc.so and/or atrc.so.6.0 (Real binary codecs) necessary
for certain Real input clips. This build now selectively statically links
prerequisite libraries leaving base system libraries as dynamic.
requirements are similar to flixd so should not affect the binary’s
ability to load. should this become an issue and a fully static binary is
required, the sources are available via: http://www.on2.com/gpl/mplayer
Bug fixes:
- fix crash in FE2_FILTER_RESAMPLE caused by the demuxer producing 0 byte
audio frames. this was only observed under windows but had the potential of
causing a crash on either platform.
- create key frame when navigation cue point(s) are set with FE2_FLV_CUEPT_NAV
- fix encoder hang when specifying an explicit framerate
w/FE2_FILTER_FRAMERATE. in addition to the fix made in v8.0.8.1 there was
another case when using either FE2_FILTER_ADAPTIVE_DEINTERLACE or
FE2_FILTER_CROP, or should the input frame need to be extended or
color converted (windows only), that could cause a hang to occur.
- (linux) revert LAME library to 3.96.1. w/certain input files 3.97 currently
produces encode errors.
