3 According to [Mark Pilgrim][MP], video embedded in the following
4 manner should work for Firefox 3.5+ and Opera 10.5+ (playing the ogg
5 movie), Safari, iPhones, and Androids (playing the mp4 movie), and
6 Chrome 4+ playing either one. If you're not running one of those
7 browsers, you can download the video and play it in an external player
10 My digital camera takes movies in
12 * Container: mov,mp4,m4a,3gp,3g2,mj2
13 * Video: mjpeg, yuvj420p, 640x480, 10422 kb/s, 30 tbr, 30 tbn, 30 tbc
14 * Audio: pcm_u8, 8000 Hz, 1 channels, s16, 64 kb/s
16 Encode your movie with something like (tagging flags removed)
18 ffmpeg2theora --endtime 120 --optimize movie.mov
20 ffmpeg -i movie.mov -t 120 -acodec libfaac -aq 200 -ac 1 -s
21 640x480 -vcodec libx264 -preset slower -vpre ipod640 -b 800k -bt
22 800k -aspect 640:480 -threads 0 movie.mp4
24 For `-vpre`, take a look in `/usr/share/ffmpeg/`, which usually
25 contains a bunch of pre-configured settings. The parameters for
26 baseling H.264 [should be][H264]:
28 * H.264 Baseline: `avc1.42E0xx`, where xx is the AVC level
29 * Low-Complexity AAC: mp4a.40.2
31 The `slower` preset used to be a `vpre` file, but [became a `-preset`
32 option][preset-slower] 30 commits before the 0.7.1 release. The
33 preset options came in [one commit eariler][preset], but this doesn't
34 seem to have percolated through to the `man` page yet.
36 You should use ffmpeg2theora v0.26 or greater, as v0.25 has
37 audio/visual syncing issues.
39 To embed the movie, include something like:
41 <video preloads="none" controls="controls" width="640" height="480">
42 <source src="movie.mp4"
43 type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' />
44 <source src="movie.ogv"
45 type='video/ogg; codecs="theora,vorbis"' />
46 <p>Your browser does not support the <video> tag, try
47 downloading the video and playing it in an external player.
49 <img width="600" src="../2011.01.20.12.33.54.jpg" />
52 <a href="movie.ogv">Ogg/Theora/Vorbis</a> or
53 <a href="movie.mp4">Mpeg4/H.264(ConstrainedBaselineProfile)/AAC</a>.
