Some of the codec names are changed in the latest FFmpeg builds. XviD is there as XviD (for older FFmpeg versions) and XviD (Lib) for newer. You can also override any basic setting on the video command line, so if you put -vcodec h64 or lib圆4 there, the basic setting is ignored. I can also add it to the default options in the next version. Read the chm help about the codecs database (Appendix first item). After that you'll probably be asked to add your so called "codec label" to the database.

Thanks for sharing your work! You can add (any) codec easily yourself by overwriting the video codec field and then press enter. I think adding x264 and Flash support would open up this application to a much larger audience, that's just an opinion so take it as you will. mp4 container? All the current ffmpeg builds natively support x264. I had a look at your application, pretty cool stuff, nice work! I have been using ffmpeg and AviSynth for quite a while now also, I am curious as to why there are no options for x264 or XviD in an.
