This will definitely work better for multiple player scenarios and avoid firing a huge amount of network requests. Metadata loading will now only happen when clicking play and not simultaneously for multiple players. I was wondering if Plyr could have (or if it is even possible) some type of internal socket management/handling capability to avoid hitting browser limitations (by closing or reusing open sockets)?Ī workaround for this issue would be fixing Issue #1201 and just don't preload any metadata at all.

#Html5 audio preload update#

But then when preloading metadata starts, sockets are not being handled correctly, and these limits are being hit really quickly if you update multiple players simultaneously.Ĭlearly this behavior will be different from browser to browser, since Chrome seems to have no issue. and it seems at some point this is working correctly. Interesting is that the API source setter starts by canceling networks requests. Also, all other players will also get stuck and won't react properly to click events. Wait for a play event before downloading anything. This attribute accepts three possible values: none Do not preload any media. I mentioned the preload attribute in the previous article. and somehow this will affect Plyr's internals, perhaps due to some events getting hung up. The good news is that at the time of writing, it’s estimated that around 80 of browsers now support HTML5 audio. If one tries to click play directly in one of these players, these will falls in an eternal loading wait.Note: if I increase max connections in Firefox config, this is no longer an issue.Īs a consequence, the players which have data preloading tasks hung will not be playable. As a consequence, browser max parallel socket limitations (refer to ) is being hit and some of the requests are getting hung "indefinitely". Since the preload function is not being respected by the source setter (see Issue #1201), a huge bulk of metadata requests (associated to preloading) are being triggered. The preload value is ignored if the audio is.

element specifies if and how the audio file is loaded after the page loads.

This seems to be only an issue with Firefox, while Chrome is 100% working during my tests.

(This will cause the user agent to invoke the objects resource selection algorithm before returning. If src is given, then set an attribute value for audio using 'src' and src. Set an attribute value for audio using 'preload' and 'auto'.

Note: this issue was originally opened under issue #1201, this explains better how I got to this particular issue Let audio be the result of creating an element given document, audio, and the HTML namespace. This works perfectly fine and preload attribute in the audio tag is being respected (as a consequence no network requests are being made and timeDuration displayed is 00:00, like expected). The sources locations are being loaded initially (on page load) directly in the HTML and then by calling Plyr's constructor with the associated DOM selectors. I have a scenario where I am loading several audio players in the same page (~10-50 per page). Hints that the browser shouldnt buffer the audio itself until the user activates the controls, but that metadata like duration and tracks. This is the simple approach, but if you are already using jQuery on your webpage, I note that this offers elegant alternatives.It seems metadata preloading is exhausting browser parallel sockets and hanging players (multiplayer scenario).

You could alternatively use the onmouseover attribute so that the audio tag is added on hover.Īdd the preload attribute to the generated code if you wish. When the person browsing clicks on the spanned text, the javascript fires and appends the tag. The src, crossorigin, preload, autoplay, loop, muted, and controls attributes are the attributes common to all media elements. What this does is to define a list item containing a text span. T.innerHTML=t.innerHTML+' No audio tag support' Īnd then use DHMTL to dynamically add the audio tag, for example: Γεια σας In a few pages where I had this problem, I add a small script to my page headers: That being said, playing sounds automatically on a web page should be avoided as this. Notice the autoplay attribute which is used to play audio files automatically. mp3 file from your webserver and plays it.

Here is the most basic use of the HTML
