When a player is created without an id on the embed code, Video.js automatically assigns it one based on an auto-incrementing number (a.k.a. a GUID). For the longest time, this has happened to result in the default id of the first player being vjs_video_3.
It was never intended for users to rely on this value being consistent, but users do strange and inadvisable things.
PR #6103 had an unintended side effect in that it changed the default id to vjs_video_2, which we worry could affect some users of Video.js.
Reimplementation of https://github.com/videojs/video.js/pull/2192
on current code. Seems to work but has not been carefully tested,
especially on conditions such as slow networks and complex tracks.
For https://github.com/videojs/video.js/issues/5252
A `preloadTextTracks` tech option is added, set to true by default,
to keep current behavior intact. Alternate behavior can be enabled
by setting this to false.
This delays loading of the VTT cue files until they are selected.
For sites like Wikipedia that tend to have large numbers of
crowdsourced subtitles and can show many files together on one
page, this saves a lot of unnecessary network transfer and API
hits.
Does mean there may be dropped cues while switching to a track
that requires on-demand loading.
Example usage:
videojs(element, {
html5: {
preloadTextTracks: false
}
};
On iOS, when disconnecting the headphones, we may receive a stalled or suspend event. In those case, we may actually still have buffer available for us to play through rather than actually having stalled or suspended. In those cases, we should pause the player to prevent playback issues.
This will prevent a null exception when a video.js is implemented in a 'display:none' iframe on Firefox (<62).
This is a fix in continuation of the PR #3664 regarding a bug in Firefox https://bugzilla.mozilla.org/show_bug.cgi?id=548397
Currently, zh-CN and zh-TW are used as shorthands for Simplified and Traditional Chinese character sets, respectively. However, they carry with them a built-in assumption about the geographic locale which may not be appropriate in all cases.
The codes zh-Hans and zh-Hant are more correct in that they refer only to the character set and not the geographic locale. Further specificity is available via codes like zh-Hans-CN.
PR #5083 introduces a fix to #5624, an issue with click events when
Polymer's tap gesture is being used. However, this causes an issue where
`player.on('click')` no longer triggers from the play toggle. Thus, we
revert the change. In addition, looking at Polymer 2 and 3, they
recommend against using the tap gesture.
Fixes#6092
The WICG spec calls out only two events, enterpictureinpicture and
leavepictureinpicture. We should try and only use those.
If pictureinpicturechange is still necessary, it can be re-added at a
later date.
