Everyone is asking about Gspot. I am pretty sure most of you know it. May be different meanings... :-) Anywho, Gspot is a free utility that tells you what the media is using codec-wise. I use it sometimes to convert or to find out what codecs are needed to re-code... here is the official definition... ● v2.21: Fully resizable main dialog and more... 12 Jul 03: build 030711 fixes integer aspect ratio & broken .wav file handling ● Establishes what video codecs (audio and video) are required to play an AVI file. ● Determines whether these codecs are installed on your system. ● Isolates problems associated with these codecs. ● Simple operation - Basic use: "File > Open", then read results ● Identifies download induced problems (truncated files, "cooked" files, etc.) ● Shows framerate, duration, aspect ratio, bitrates, AVI structure info, and more. ● Displays and allows editing of RIFF info (title, etc); displays "hidden" ASCII info. ● Drag and Drop and "Send To" support, multi-file (batch) processing support ● Copy/Paste or text export GSpot information - format is user configurable. ● Built-in database of 350 video and 150 audio codec types ● Advanced UI including "dual-mode" and hyperlinked "persistent" tool tips ● Full support for OGG media files as well as AVI stream formats ● Identification (only) of non-AVI files (.mpg, .mov, .qt, .rm, .swf, .wmv, .asf, etc.) ● Supports VFW, ACM, DirectShow and DMO codec types (audio and video) ● Win95/98/ME/NT/2K/XP ● No Install (optional), No spyware, No advertising, No registration ● Free -------------------------------- my two cents ...;-)
