Description André Costa 2018-12-09 06:39:46 PST

When I try to play animated GIFs or videos through Whatsapp Web interface on Epiphany, they play just the first time, further attempts fail (the multimedia controls appears, but are not responsive, and the video/GIF image is replaced by a white square).

I am on Fedora 29, these are the relevant packages installed:

Please let me know if I can provide any additional info.

This has been happening for at least half a year or so, on normal non-YouTube video elements. It's not reliably reproducible for me but happens maybe 50% of the time.

i.e. this is definitely not specific to Whatsapp.

This is a known bug in the current MSE implementation.

Comment 4 Michael Catanzaro 2018-12-10 07:15:40 PST

Could it be related to bug #192530? I have a feeling a LOT of our weird problems video problems could be related to that issue.

Any plans to fix it? This is really bad.

Yes. I'm taking this in mind in my rework of the playback pipeline, but that is a long task.

Is this really a MSE issue? At least audios are played using <audio> here, over blob: URIs. See bug 211627.
