To encode a video file for use in HTML5 video compatible browser (firefox 3.5 and above supports HTML5 video), use the command:

$ ffmpeg -i in.flv -vcodec libtheora -sameq \
   -acodec libvorbis -ac 2 -sameq out.ogg


Finally use it in your page:

<video src="out.ogg">
Your browser does not support HTML5 video.
</video>


Reference: HTML 5 <video> Tag.

To stream video content using Video View Portlet, I had to re-encode some videos to flv format. This is pretty simple in Linux:

$ mencoder -oac copy -ovc lavc -o out.flv in.avi


-oac means Output Audio Codec and -ovc means Output Video Codec. The various options for -oac:

copy no encoding, just streamcopy.
pcm Encode to uncompressed PCM.
mp3lame Encode to MP3 (using LAME).
lavc Encode with a libavcodec codec.

The options for -ovc:

copy no encoding, just streamcopy.
raw Encode to an arbitrary uncompressed format (use ’-vf format’ to select).
lavc Encode with a libavcodec codec.
