I'm looking around on the web for ways to convert wmv files to mp4. So
far the most common solution seems to be ffmpeg but when I try that it
doesn't seem to understand the video files. The most common type of
comment people give is that this should be straight forward if 32-bit
codecs are installed. I'm running 64-bit and don't see what flags I
might need to set to get that?
There is a library (libwmf) which advertises the ability to do this
but I don't seem to be using it in any application right now:
* media-libs/libwmf
Available versions: 0.2.8.4-r4 {{X debug doc expat xml}}

Description: library for converting WMF files
mark@c2stable ~/WMV-Test $ equery depends libwfm
* These packages depend on libwfm:

Anyone doing this successfully today or what to suggest how to do this?
Thanks,
Mark
