<h3>With fallbacks</h3>
<h3>HLS only:</h3>
<p>HLS with VP9 (.mp4)/MJPEG (.mov) video tracks and Opus/MP3 audio tracks. Video.js enabled to provide HLS-over-MSE for Chrome/Firefox.</p>
<p>HLS with correctly-labeled VP9 (.mp4) and MJPEG (.mov) video tracks and Opus (.mp4, for Chrome/Firefox) and MP3 (.mp3, used by Safari) audio tracks. Video.js is enabled but will not yet override the native HLS in Safari Desktop.</p>

<h3>WebM or HLS:</h3>
<p>WebM VP9/Opus, WebM VP8/Vorbis, or HLS. Current versions of desktop Safari should see one or the other WebM, and those that fall back to the HLS may or may not work.</p>

<p>Current behavior:</p>
<p>Browsers that play the VP9 track will get sharp video, those that play the MJPEG track will get blurry video. Audio should sound the same either way.</p>

<li>macOS 13's Safari 16 plays MJPEG on most of my test machines, except a 2015 MacBook Pro with Intel graphics unless the type is lied about.</li>
<li>iOS 16 plays VP9 if supported, or MJPEG if no hardware codec</li>
<li>Those last two will also play h.263 or MPEG-4 visual <a href="fmp4-lies.html">IF labeled as if h.264 in the playlist</a>; MJPEG can be properly labeled as "jpeg". I haven't found a supported labeling that is correct yet.</li>
<li><i>no access to iOS 13-15</i></li>
<li>iOS 13 doesn't seem to like mjpeg in .mp4, but .mov is fine</li>
<li>iOS 12 doesn't seem to like any version on an old iPad Air, except with h264 video</li>
<li><i>no access to iOS 11</i></li>
<li>iOS 10 on iPhone 5C plays h.263, or mpeg-4 visual IF labeled as false avc1.blah. It will also play mjpeg if so mislabeled, but only in .mov not in .mp4 as above.</li>
<li>iOS 9 doesn't understand the required version of HLS playlist format, and fails.</li>
