From e0a05c5908cd30b05e6ffcfe134038d91cbf5249 Mon Sep 17 00:00:00 2001 From: paweldomas Date: Wed, 21 Sep 2016 15:02:19 -0500 Subject: [PATCH] ref(LargeVideo): move VideoContainer to separate file VideoContainer is a separate being which implements the LargeContainer and it's confusing to have it in the same file. This was encouraging to access private parts of the VideoContainer directly(not through the interface). --- conference.js | 4 +- modules/UI/videolayout/LargeVideo.js | 382 +--------------------- modules/UI/videolayout/VideoContainer.js | 385 +++++++++++++++++++++++ modules/UI/videolayout/VideoLayout.js | 6 +- 4 files changed, 395 insertions(+), 382 deletions(-) create mode 100644 modules/UI/videolayout/VideoContainer.js diff --git a/conference.js b/conference.js index 0b8307c37..b0edba985 100644 --- a/conference.js +++ b/conference.js @@ -39,7 +39,7 @@ let connectionIsInterrupted = false; */ let DSExternalInstallationInProgress = false; -import {VIDEO_CONTAINER_TYPE} from "./modules/UI/videolayout/LargeVideo"; +import {VIDEO_CONTAINER_TYPE} from "./modules/UI/videolayout/VideoContainer"; /** * Known custom conference commands. @@ -1424,6 +1424,8 @@ export default { APP.UI.addListener(UIEvents.PINNED_ENDPOINT, (smallVideo, isPinned) => { var smallVideoId = smallVideo.getId(); + // FIXME why VIDEO_CONTAINER_TYPE instead of checking if + // the participant is on the large video ? if (smallVideo.getVideoType() === VIDEO_CONTAINER_TYPE && !APP.conference.isLocalId(smallVideoId)) { diff --git a/modules/UI/videolayout/LargeVideo.js b/modules/UI/videolayout/LargeVideo.js index e5449dc02..8c145e77e 100644 --- a/modules/UI/videolayout/LargeVideo.js +++ b/modules/UI/videolayout/LargeVideo.js @@ -1,388 +1,10 @@ /* global $, APP, interfaceConfig */ /* jshint -W101 */ -import UIUtil from "../util/UIUtil"; -import UIEvents from "../../../service/UI/UIEvents"; -import LargeContainer from './LargeContainer'; -import FilmStrip from './FilmStrip'; import Avatar from "../avatar/Avatar"; import {createDeferred} from '../../util/helpers'; - -const FADE_DURATION_MS = 300; - -export const VIDEO_CONTAINER_TYPE = "camera"; - -/** - * Get stream id. - * @param {JitsiTrack?} stream - */ -function getStreamOwnerId(stream) { - if (!stream) { - return; - } - if (stream.isLocal()) { // local stream doesn't have method "getParticipantId" - return APP.conference.getMyUserId(); - } else { - return stream.getParticipantId(); - } -} - -/** - * Returns an array of the video dimensions, so that it keeps it's aspect - * ratio and fits available area with it's larger dimension.
