VirtualDub 1.5.10 released
VirtualDub is a video capture/processing utility for 32-bit Windows platforms (98/NT/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.VirtualDub 1.5.10 is out — it fixes a couple of critical crashes, one of them being the VideoCD crash, and the other being a stability issue on Windows 95/98 systems. Full props go to “fccHandler” for finding the bug in the source code that caused the latter problem. This version also fixes a few random problems I happened to identify on the way. Work is still progressing on the experimental version, which I hope to get to releasable ?￠a??a€? major-embarrassment-free ?￠a??a€? status in the near future.
1.5.10 contains a workaround for a rather sticky problem with certain filters, such as Deflicker. Basically, some filters that rely on separate analysis and render passes make a slightly invalid assumption ?￠a??a€? that once the analysis pass finishes, the next startProc call received will be the user starting the render pass. Well, this isn’t actually guaranteed in the spec and recent 1.5.x versions break such filters when they refresh the output pane after the analysis. The result is that the filter dumps its analysis data and builds a one-frame trace before the render starts. Whoops. This problem actually exists in all versions of VirtualDub, but in earlier versions you have to explicitly step the current frame position in order for the filter chain to restart, whereas 1.5.9 will do it any time the output pane needs to be refreshed and the filter chain is idle. A possible workaround is to disable the output pane before doing the analysis pass, although I haven’t actually tried this.
