8/3     What plug-in do I need to play AVI's on my pc?
        \_ on Windows?  Windows Media Player?
        \_ i bet it's divx avi.  search the web for divx codecs
           \_ if so, and you're not planning on doing encoding, install
              ffdshow instead. http://cutka.szm.sk/ffdshow/index.html
              It'll decode divx3/4/5 and xvid video and has good
              postprocessing control. --jameslin

3/21    Browser Plug-In you must get: Ghostery. It gets rid of a bunch of
        ad trackers on a web site, resulting in really fast load times.
        For example, a typical media site will require 10-15 trackers
        (you know, those URLs that track your activities so they can
        target you better). Ghostery kills them.

2/19    I program a lot by sshing to a Linux cluster.  So I'm used to using
        Xemacs to code.  This works fine from a Linux or Windows workstation,
        but sometimes I have to use a Mac.  On Mac, the meta is usually
        bound to option, but that often doesn't work over ssh for some reason.
        This makes using emacs a real pain.  Any suggestions on how to fix it?

        the following?
        - Windows 8
        - Windows Server "8"
        \_ Because when they didn't do it, code didn't see the '\0'
           and went over?  Looks better than '8','\0' *shrug*

For now it is just an alpha version of ffdshow, but it seems to be working quite good. You can download it from ffdshow SourceForge page where it is stored in ffdshow-alpha package. This build was prepared by Athos, who agreed to provide them regularly when some new features or bug fixes will be ready. Presets can be selected manually or if automatic preset loading check box is selected, preset is selected according to file name of played AVI (of course if such preset exists). Small button on left of presets area puts file name of played AVI into preset name combo box. Backslashes are reverted, because windows registry doesn't like them. Detection of name of played file is very simple and may not always work Saving presets: type new preset name and press Save button. Loading presets: select existing preset and press Load button. If preset with that name doesn't exists, nothing will happen. Removing presets: select preset you want to remove and press Remove button. Active preset settings are automatically saved when closing configuration dialog with OK button. This is only first attempt to get some preset system work. If you have ideas about making it better or you've found a bug in preset handling, please let me know. IDCT Controls which IDCT function is used during decoding process. But if you will get slightly pinkish image, try normal IDCT. Reference IDCT is most accurate but very slow and is used only for testing. But when I switched back to normal IDCT routine and tested it with some DIVX3 encoded videos new problem appeared (but pink problem was gone): horizontal stripes. Bug is not in ffdshow, because identical problems can be seen is mplayer too. The only IDCT which worked with both test videos was reference IDCT from XMPEG, but that was unusable because it it terribly slow. Solution for now is use two IDCT routines: normal libavcodec IDCT for DIVX4, DX50 and XVID and simple libavcodec IDCT for DIVX3. I will send bug report to ffmpeg development team and try to find some fast and precise enough IDCT implementation. Features: - nice installer (NSIS) - fast video decompression using libavcodec and IDCT plugins from FlaskMPEG and XMPEG - support for different codecs: XviD and all DIVX versions (DIVX 5 support is incomplete) - image postprocessing for higher playback quality - automatic quality control: automatically reduces postprocessing level when CPU load is high - luminance correction It is still in heavy development and getting better each day. There is also postprocessing code from mplayer compiled with cygwin and with MMX, 3Dnow! Xvid color conversion routines are used again, so it should work on more graphics cards. Filter has simple configuration dialog, where you can set postprocessing level. Decoder is incomplete, slow (doesn't use MMX), propably will not work with your videocard (worked with my ATI Radeon), at beginnig it has only green picture (until next keyframe, then it is ok) and has no postprocessing. And now something good: with only small code modifications it could play divx3, divx4, divx5 (libavcodec supports b-frames, qpel, gmc) and of course xvid. When it will be compiled with gcc using inline assembler it will be propably fastest mpeg4 decoder for Windows (for comparison see mplayer developer mailing list) and it might be possible to use postprocessing code from mplayer.
