However, some portions of the HTML5 specification were still being implemented by browser makers.

As of January 2015, [[YouTube]] defaults to HTML5 players to better support more devices. HTML5 needs less processing power making it run faster on all browsers. The [[multimedia]] integration with HTML5 is quite easy and creates better support for live video [[Streaming media|streaming]] on mobile devices also.<ref>{{cite web|work=YouTube Engineering and Developers Blog|title=YouTube now defaults to HTML5 <video>|url=https://youtube-eng.googleblog.com/2015/01/youtube-now-defaults-to-html5_27.html|access-date=2018-11-03|archive-date=2018-09-10|archive-url=https://web.archive.org/web/20180910204225/https://youtube-eng.googleblog.com/2015/01/youtube-now-defaults-to-html5_27.html|url-status=dead}}</ref>

Flash iswas not an [[open standard]]. It iswas controlled by one firm, [[Adobe Systems]]. In contrast, HTML5 is controlled mostly by a committee, the Web Hypertext Application Technology Working Group ([[WHATWG]]).<ref name="thoughtsFlash">{{cite web|last=Jobs|first=Steve|authorlink=Steve Jobs|date=April 29, 2010|title=Thoughts on Flash|url=https://www.apple.com/hotnews/thoughts-on-flash/|url-status=live|archive-url=https://web.archive.org/web/20170615060422/https://www.apple.com/hotnews/thoughts-on-flash/|archive-date=June 15, 2017|accessdate=March 24, 2022|website=[[Apple Inc.]]}}</ref>

Various people have praised Flash over the years for rendering consistently across platforms. Constructing sites in Flash iswas a way to prevent [[Fork (software development)|''code forking,'']], whereby different versions of a site are created for different browsers.<ref>{{cite book |author=Ka Wai Cheung and Craig Bryant |title=Flash Application Design Solutions: The Flash Usability Handbook |page= 6 |publisher=Apress |year= 2006 |url= https://books.google.com/books?id=49OwlbrMc-oC&q=flash+cross+browser&pg=PA6|isbn=9781590595947 }}</ref><ref>{{cite book |first=Rob |last=Huddleston |title=Flash Catalyst CS5 Bible |publisher=Wiley |year= 2010 |url=https://books.google.com/books?id=crN1zsYwYAYC&q=flash+cross+browser&pg=PT39|isbn=9780470767948 }}</ref>

Speaking at 'Adobe Max' in 2011, Itai Asseo likewise said that, unlike HTML5, Flash offers a way to develop applications that work across platforms. HTML5, he said, is currently implemented differently (if at all) by different browsers. Although the Flash browser plugin is not supported on the Apple iPhone OS, Flash applications can be exported to Adobe AIR, which runs on that operating system as a native application. In the same talk, Mr. Asseo lamented the return to another browser war (as seen in the late 1990s). If Flash falls out of favor, he said, web developers will either have to develop many different versions of their web sites and native applications to take into account different HTML5 implementations, deny access to browsers that do not support their version of HTML, or dramatically reduce the functionality of their sites in order to deliver content to the least-advanced browser.<ref>{{cite web|author=Itai Asseo|title=The Death of Flash|url=http://tv.adobe.com/watch/max-2011-envision/the-death-of-flash/|access-date=November 19, 2011}}</ref>

Flash hashad a better performance than HTML, asaccording to a comparison of Flash with HTML in 2010 which listed Flash as being faster than the other technologies, when used for non-video animations, although they are catching up.<ref>{{cite web|title="HTML5" versus Flash: Animation Benchmarking|url=http://themaninblue.com/writing/perspective/2010/03/22/}}</ref><ref>{{cite web|title=Flash vs HTML5 Performance (Updated January 2012)|url=http://pacoup.com/2011/02/03/flash-vs-html5-performance/|access-date=2012-11-20|archive-url=https://web.archive.org/web/20121017051052/http://pacoup.com/2011/02/03/flash-vs-html5-performance/|archive-date=2012-10-17|url-status=dead}}</ref>

Some users, more so those on [[macOS]] and [[Linux]], have complained about the relatively high [[CPU time|CPU usage]] of Flash for video playback.<ref>"Flash – CPU Usage – FPS – Frame Rate."

Reader discussions, Adobe Support Forums. 10 December 2010]</ref>{{Unreliable source?|date=December 2010}} This was partially because the Flash plugin did not use the GPU to render video. Adobe has responded to some of those criticisms in the 10.1 and 10.2 releases of the Flash plugin by offloading H.264 video decoding to dedicated hardware and by introducing a new video API called Stage Video.<ref>{{cite web

=== DRM ===

Flash includesincluded [[digital rights management|DRM]] support. The main HTML 5 standard does not include any [[digital rights management]] functionality directly, instead the [[Encrypted Media Extensions]] (EME) specification describes [[API|application interface]] (API) for communication channel between web browsers and digital rights management (DRM) agent software.

Historically, before EME introduction implementations could support DRM, for example in [[codec]]s.<ref>{{cite web|url=http://www.w3.org/html/wiki/FAQs#Is_there_support_for_digital_rights_management_.28DRM.29_in_HTML5_video.3F |title=FAQs - HTML Wiki |publisher=W3.org |date=2011-02-22 |access-date=2012-06-18}}</ref> The proposal to add DRM features to HTML5 itself has been criticized by those who consider openness and vendor-neutrality (both server- and client-side) one of the most important properties of HTML, because DRM is incompatible with [[free software]],<ref>{{cite web

=== Accessibility ===

Both Flash and HTML text can be read by screen readers. However, special care must be taken to ensure Flash movies are read correctly. For example, if a Flash movie is set to repeat indefinitely, this can cause a screen reader to repeat the content endlessly. Selecting the "Make object accessible" check box in Adobe Flash Professional willwould create a text-only version of the object for screen readers.
