FFMPEG Convert HTML 5 Video NOT Working

Question

I am using FFMPEG to convert a video to .mp4, ,ogg, .webm so that it may be viewed in all HTML5 capable browsers using the video tag

Answer 1

Having tried most of the suggestions above, here's what actually worked for me to convert wmv files to small mp4, webm, ogg on a Windows7-64 machine:

64bit\ffmpeg -i test.wmv test.mpg

old\ffmpeg -i test.mpg -vcodec h264 -s 320x240 test.mp4

32bit\ffmpeg -i test.mpg -vcodec libvpx -acodec libvorbis -f webm -s 320x240 test.webm

32bit\ffmpeg -i test.mpg -vcodec libtheora -acodec libvorbis -s 320x240 test.ogg

old\ffmpeg is version SVN-r5570

64bit\ffmpeg is version N-38292-ga4c22e3 built 2/27/12 14:55:47

32bit\ffmpeg is version N-39267-g4082198 built 3/25/12 20:25:08

(Only the 64 bit version would read the wmv, so I used it to convert to mpg as a common format. Only the old ffmpeg would create an mp4.)
