I’ve got some video from the web in Flash video format (.flv). I want to convert it to h.264.

I’ve got Perian installed. QuickTime seems to play the video fine, but when I use any of the options to export it, I get audio, and a blank white screen instead of the video footage.

Are there any Mac OS X apps that convert FLV to h.264? (Command-line or GUI.)

@Doug: definitely in the same ball park, but that question doesn’t mention Flash video, and mine doesn’t specify that the app has to be free. –  Paul D. Waite Sep 7 '10 at 18:05

I can't believe no one mentioned Evom on that thread, either. Dead-simple one-drop conversion to standard iPod format, and free. –  ghoppe Sep 7 '10 at 18:44

Care to elaborate on what's so awesome about Evom @ghoppe? –  Ivo Flipse Sep 9 '10 at 11:33
    
Evom is free, made by "little app factory" (a well known mac developer), and it works fantastic!! –  bentford Jul 9 '11 at 6:01

You can do this with ffmpeg and no transcoding if the FLV contains an already H264 encoded video (quite common). Here's how I got it (assuming you have git and Xcode installed, e.g. that you can compile)

git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
./configure --enable-shared --disable-mmx --arch=x86_64
make
make install
ffmpeg -i "file.flv" -vcodec copy -acodec copy file.mkv

Optionally, you can convert the file.mkv to MP4 in Subler

VLC doesn't just play anything, it can also reencode things. If you need batch conversion with a GUI, you could do worse than AppGeeker (flv to mp4 h.264 mac). If you want batch conversion, and insanely precise control at the expense of an insanely obtuse command line interface, ffmpeg is the best thing ever.
