Main drivers of bloat seem to be different formats available, and different subtitles.

In IRC we suggested degrading the experience for non-JS clients to have only one set of subtitles (page content language?) and one video resolution (biggest?), and fetching the rest of the data async via JS after the page is painted.

Once we're able to move to MPEG-DASH streaming we could have one or two progressive-download sources at a reasonable default resolution, plus the MPEG-DASH manifest listed as first source. We might be able to shove the timed text track references into the .mpd manifest too, though that would mean they don't work with JavaScript disabled.

Neat. That's T44591, right?

We might be able to shove the timed text track references into the .mpd manifest too, though that would mean they don't work with JavaScript disabled.

Given the size impact, what do you think about only shipping the content language i18n to non-JS users and the rest are in the manifest?

@brion love to hear what you think of my idea to only include the default translation for the subtitles in the HTML and load the others via Javascript

Jdforrester-WMF updated the task description. (Show Details)Mar 27 2022, 10:46 PM

Have updated the example HTML outputs here; the growth is formats (VP9 is now available), and for Parsoid partially offset by the changes to the <track> output:

Before	Δ	After
`<track`	=	`<track`
`kind="subtitles"`	=	`kind="subtitles"`
`type="text/x-srt"`	=	`type="text/x-srt"`
`src="https://commons.wikimedia.org/w/index.php?title=TimedText:Sneak_Preview_-_Wikipedia_VisualEditor.webm.bn.srt&action=raw&ctype=text%2Fx-srt"`	+	`src="https://commons.wikimedia.org/w/api.php?action=timedtext&title=File%3ASneak_Preview_-_Wikipedia_VisualEditor.webm&lang=bn&trackformat=srt&origin=%2A"`
`srclang="bn"`	=	`srclang="bn"`
`label="বাংলা (bn) subtitles"`	-	`label="বাংলা ‪(bn)‬"`
`data-mwtitle="TimedText:Sneak_Preview_-_Wikipedia_VisualEditor.webm.bn.srt"`	-	`data-mwtitle=""`
`data-dir="ltr"`	=	`data-dir="ltr"`
`id="mwDQ">`	=	`id="mwEw">`

Once videojs is rolled out, there are certainly some things we can work on to reduce the size. I personally think:

We should just drop some of the sizes for VP8. (160p, 360p and 720p seems like enough VP8 to me)
data-title and data-short title are things to look at. They were for kaltura player, maybe we no longer need them
We should consider removing the original version of the file (as they tend to have lots of problems with profile conformity etc)
We can dump all but the default text tracks like I suggested
The duration and bandwidth numbers can have very long floating point numbers, which we can trim

@brion do you agree with this ? I don't think we need any of these attributes any longerl. At most perhaps the data-width/height one if we ever want to auto select a lower resolution for inline playback perhaps, like we used to do in the past ?

Remove from <source>

data-bandwidth
data-framerate
data-width
data-height
data-title
data-shortitle

Add to vjsplayer a function that uses data-transcodekey to retrieve and generate data-title and data-shorttitle for the resolution switcher menu.
