Steps to reproduce

Open directory with many videos
Click on any video and press arrow (next video) many times.
On 10th or 15th time (of pressing next) video will not load. It will only show black player screen. After that nextcloud will not respond for any request. If u want to unhang it, you have to close this nextcloud tab, and open new one.

Expected behaviour

Videos should be listed without hangs. Nextcloud should answer for requests.

Actual behaviour

Video hangs, and its impossible to open new nextcloud tab (it will not respond)

PVince81 commented 3 years ago

can you check the browser log and maybe the network console ?

it might contain clues about whether the 15th video failed loading or not

also see if the network request from the previous videos have been cancelled or whether the browser is still trying to download parts of them

motodoros commented 3 years ago

@PVince81 Hello! All information in attachments. There is no clues about closing previous videos. THis bug works even if I stop each video before switching next.

I am pretty sure that this is the problem here: https://github.com/nextcloud/server/issues/8161

motodoros commented 3 years ago

@szaimen Thanks, as I see there is no solution :)

motodoros commented 3 years ago

Is it possible to solve it somehow?

szaimen commented 3 years ago

@kesselb gave a few tips here: https://github.com/nextcloud/server/issues/22334#issuecomment-678343186 but I tried it and it didn't make any difference in my testing...

motodoros commented 3 years ago

Solved in NC 21.0.1
