The README is written in Chinese so here are a few points from this project&#x27;s README:<p># Rationale<p>Using Flash to watch videos on Macbooks generates a lot of heat. Many Chinese video websites have near-zero support for HTML5 videos on PC&#x2F;Mac browsers. The old method of using &lt;video&gt; and streaming from the mobile version sites can&#x27;t get you 1080p videos.<p># Rough Implementation<p>This project plays FLVs in browsers by slicing them into fragmented MP4 (fmp4) files. A set of Stream operations are defined in mediaSource.js, which in turn depends on .&#x2F;flvdemux.js for demuxing the FLV and mux.js (from videojs) for various other functions. Uint8Array is used for speed.<p>The rest of the project consists mostly of UI (keyboard only), file-sneaking functions for video sites and things like flash blockers.<p># Performance<p>20~40ms transcoding time for a 10s video segment on i5 2.9G.<p># Availability<p>Available as Chrome extension &quot;hoihfdmeofbkbbjpieicemdhmjgfdihm&quot;.
