<h1>HLS VP9/fMP4 test</h1>

<h3>With fallbacks</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>
<div>
<video controls width=640 height=360>
<source type=application/vnd.apple.mpegurl src=fmp4.vp9-mjpeg.mov.m3u8>
</video>
</div>
<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>
<ul>
<li>MSE-based streaming with VHS
<ul>
<li>Firefox seems to work with VP9 & Opus tracks via video.js</li>
<li>Chrome works (needed to fix an output setting)</li>
<li>(disabled) Safari uses the MP3 audio tracks and VHS gets confused because it tries to parse them as MP4 (not Safari's fault)</li>
</ul>
</li>
<li>Apple HLS player
<ul>
<li>macOS 13's Safari 16 plays MJPEG.</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>
</ul>
</li>
</ul>
