Can AviSynth handle MTS files? I want to process MTS (MPEG Transport Stream) files from an AVCHD camcorder in AviSynth. Displaying with AviSource() says that the file couldn't be opened, displaying with DirectShowSource() says that the format is not supported.

I found no information about MTS on the AviSynth wiki. The list of source filters has nothing on MTS or TS. I found a thread about MTS and VirtualDub but I would prefer dealing only with the source file instead of converting to another format.

Can AviSynth handle MTS files?
Use cross-platform wrapper library FFmpegSource (around FFmpeg) — particularly, its filter FFmpegSource2() (instead of built-in AviSource() or DirectShowSource()).

See AviSynth Wiki about it.
