Opens files using ffmpeg and nothing else. May be frame accurate on good days. The source is MIT licensed and can be obtained from "http://svn.aegisub.net/trunk/aegisub/FFmpegSource2/". The precompiled binary is GPL licensed. If you are religious you may consider this the second coming.
<li>Requires <ahref='http://haali.cs.msu.ru/mkv/'>Haali's Media Splitter</a> if ogm or mpeg ps/ts is to be opened.</li>
<li>Avi files with NVOPs (rarely occurs in xvid and such) will desync when these frames are encountered. Remux to mkv/mp4 before opening to solve it for now.</li>
<li>The audio sources still aren't sample accurate and sometimes exhibit many interesting issues. Dumping the audio during indexing is the only workaround.
Opens audio, <b>if an index already exists it needs to contain a suitable audio index or empty audio will be returned</b>, will invoke indexing with the defaults if no preexisting index is found
Which audio tracks to index/write to disk. Dumping a track also implies indexing since the same work has to be done anyway. It is a binary mask meaning that 7 corresponds to writing tracks 1-3. Non-audio tracks are ignored. -1 writes all tracks.
See the table below for a full description, an empty string means no processing. It is recommended to avoid the autoq option since it's currently unknown what effect it will have on the processing.

<p>
<b>threads:</b>
Sets the number of decoder threads used. Defaults to the number of cpus reported by windows. Ignored by lavc if the used decoder doesn't implement it.
</p>
<p>
<b>seekmode:</b>
Force how seeking is handled, has no effect on matroska files which always use the equivalent of seekmode=1<br/>
<b>-1:</b> linear access without rewind, will throw an error if each successive requested frame number isn't bigger than the last one, only intended for opening images but might work on well with some obscure video format<br/>
<b>0:</b> linear access, the definition of slow but should make some formats "usable"<br/>
<b>1:</b> safe normal, bases seeking decisions on the reported keyframe positions<br/>
<b>2:</b> unsafe normal, same as 1 but no error will be thrown if the exact destination has to be guessed<br/>
<b>3:</b> aggressive, seek in the forward direction even if no closer keyframe is known to exist, only useful for testing and containers where avformat doesn't report keyframes properly
</p>
<p>
<b>width & height:</b>
Width and height to resize to. Value below or equal to 0 is the same as specifying the input dimensions.
</p>
<p>
<b>resizer:</b>
Selects the resizer used for resampling the chroma planes and normal resizing. The available methods are: FAST_BILINEAR, BILINEAR, BICUBIC, X, POINT, AREA, BICUBLIN, GAUSS, SINC, LANCZOS and SPLINE.
</p>
<p>
<b>colorspace:</b>
The colorspace to convert to. The names are YV12, YUY2, RGB24, RGB32 and the empty string for same as input.
The playback aspect ratio specified by the container. FFSAR_NUM and FFSAR_DEN make up the rational number of the ratio and FFSAR is only provided for convenience.
The on playback cropping specified by the container.
</p>
<p>
<b>FFPICT_TYPE:</b>
The picture type of the most recently requested frame. Use after_frame=true in Avisynth's conditional scripting for proper results. The FFmpeg source definition of the numbers:
<li>Improved the audio decoding quality a lot by adding a simple cache, no more seeking is done when playing a file linearly and pops and other artifacts should be much more uncommon</li>
<li>Fixed a bug that would most of the time drop frame 0 and sometimes frame 1</li>
<li>Using ffms2 as a library no longer requires an installed pixfmt.h from libavutil, it is however still required to compile ffms2 and the avisynth plugin part</li>
<li>Haali's splitters have been improved for video and now have audio dumping during indexing implemented</li>
<li>SeekMode=1 has improved logic which will make it go back and decode more frames if necessary to figure out where it is, in theory SeekMode=0 should now be mostly obsolete</li>
<li>Haali's splitters are now used to open mpeg ps and ogm in addition to mpeg ts, only ogm is frame accurate at this time</li>
<li>Readded FFAudioSource support for other containers (glitches still present now and then but no separate raw cache is required and possibly less buggy)</li>
