VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/2000/XP), licensed under the GNU General Public License (GPL). It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images. I had intended for 1.6.6 to be the first stable release in the 1.6.x series, but a couple of bugs were reported that required potentially risky changes, so I decided to push 1.6.7 out as experimental again and reset the clock. Again, barring no major issues, the next release ? 1.6.8 ? will be released as stable.

1.6.7 mostly contains a bunch of minor crash fixes, but has two notable changes. One is that the AVI indices have been moved inward a couple of chunks to match the OpenDML spec; they were formerly placed at the very end, outside of any other chunk. The only reason this got noticed is that someone was comparing VirtualDub's output to their own AVI writer; I doubt anyone will notice a difference otherwise, but if there is a problem with the old index placement, it can be rectified by re-running the AVI through VirtualDub in direct/direct mode. The other notable change is that I fixed a couple of issues with audio samples being dropped at the very end of the output file.
