Hi everyone I have a problem with my VirtualDub software. I have an .AVI video which I’ve worked on a couple of weeks ago, but I need to work on it again with the VirtualDub. The thing is when I tried to open the video with the software a message appears telling me “Could’n locate decompressor for format FMP4 (unknown. VirtualDub requires a VFW compatible codec to decompress video. Directshow codecs are not suitable”. Does anyone kow where can I find such codec, and how would that work, like what do I need to do, once found the codec, so that my video can be read. Thank you thank you ! I appreciate any knid of help or hint possible...
