According to Mark Pilgrim, video embedded in the following manner should work for Firefox 3.5+ and Opera 10.5+ (playing the ogg movie), Safari, iPhones, and Androids (playing the mp4 movie), and Chrome 4+ playing either one. If you're not running one of those browsers, you can download the video an extermal player (like VLC).

My digital camera takes movies in

  • Container: mov,mp4,m4a,3gp,3g2,mj2
  • Video: mjpeg, yuvj420p, 640x480, 10422 kb/s, 30 tbr, 30 tbn, 30 tbc
  • Audio: pcm_u8, 8000 Hz, 1 channels, s16, 64 kb/s

Encode your movie with something like (tagging flags removed)

ffmpeg2theora --endtime 120 --optimize

ffmpeg -i -t 120 -acodec libfaac -aq 200 -ac 1 -s
    640x480 -vcodec libx264 -preset slower -vpre ipod640 -b 800k -bt
    800k -aspect 640:480 -threads 0 movie.mp4

For -vpre, take a look in /usr/share/ffmpeg/, which usually contains a bunch of pre-configured settings. The parameters for baseling H.264 should be:

  • H.264 Baseline: avc1.42E0xx, where xx is the AVC level
  • Low-Complexity AAC: mp4a.40.2

The slower preset used to be a vpre file, but became a -preset option 30 commits before the 0.7.1 release. The preset options came in one commit eariler, but this doesn't seem to have percolated through to the man page yet.

You should use ffmpeg2theora v0.26 or greater, as v0.25 has audio/visual syncing issues.

To embed the movie, include something like:

<video preloads="none" controls="controls" width="640" height="480">
  <source src="movie.mp4"
          type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' />
  <source src="movie.ogv"
          type='video/ogg; codecs="theora,vorbis"' />
  <p>Your browser does not support the &lt;video&gt; tag, try
  downloading the video and playing it in an external player.
  <img width="600" src="../2011." />
<p>Download as
 <a href="movie.ogv">Ogg/Theora/Vorbis</a> or
 <a href="movie.mp4">Mpeg4/H.264(ConstrainedBaselineProfile)/AAC</a>.
