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

I had the same problem with IE9 showing a red cross when trying to show the .mp4 video. Keeping it simple using ffmpeg (as Michas suggested) solved the issue for me.

The ffmpeg parameters: (I used .ogv from ffmpeg2theora as my inputfile):

ffmpeg -i input_file.ogv -vcodec libx264 -vpre hq output_file.mp4

My ffmpeg version:

ffmpeg 0.8.3
libavutil    51.  9. 1 / 51.  9. 1
libavcodec   53.  7. 0 / 53.  7. 0
libavformat  53.  4. 0 / 53.  4. 0
libavdevice  53.  1. 1 / 53.  1. 1
libavfilter   2. 23. 0 /  2. 23. 0
libswscale    2.  0. 0 /  2.  0. 0
libpostproc  51.  2. 0 / 51.  2. 0
