[v2-embed] configuration not being passed in Safari and general performance issues
Priority
Critical
Description
The iframe with the video we’re loading sends an event we listen to. Then, the video’s configuration is passed. The script in the iframe applies the configuration and loads the video. This needs to happen instantly; after a few milliseconds, the script loads the video with the default configuration.
When multiple videos are loaded on a page, Safari can’t share the configuration in time. We’ve observed a couple of performance issues where the video-related functions on our end were triggered several times.
Open the tab Console in the DevTools of the browser
Observe the log of the [v2-embed] to be present with the event video-loadedmetadata for a video id – multiple times
Expected Results
All videos have the configuration applied after loading. Autoplay videos will autoplay, but videos with disabled controls don’t have controls, etc.
Events are triggered once and functions being executed once per video
Actual Results
Not all videos have the configuration applied after loading.
Be aware that the aspect ratio is handled on our end as passed to the iframe. So, a video with this configuration seems to be handled correctly, even though the configuration hasn’t been received.
Events are triggered multiple times, and functions are executed multiple times per video. We can observe that by the logging of events of [v2-embed] being printed multiple times for the same video.
