Transcoding / Video Errors for the past week

Description of issue:

Recently our CloudBuild's just started stalling out -- a build would end up running for 2.5 hrs before it was ultimately cancelled automatically by Unity's backend.

It seems like something is wrong with the video transcoding in the builds, despite the fact that we've got the videos marked to not be transcoded.

A few high level points about our project:

* It's very video intensive, and we just added more content. The "size" reported by the last successful build was 4.5GB, and we recently added more content when it started failing.
* We have our cloud build set to a specific Unity version, and that did not change when the builds were succeeding to where they are failing now.
* There are several errors on videos in the logs for the builds that are failing after 2.5 hours. Errors are showing on videos that have existed on the project since the successful builds, and have not been changed.
* Local builds in both Windows and macOS continue to be successful.
* A clean build did not fix the issue.

Does it build locally from a fresh checkout? yes

 

Regarding the time that it started failing, in case that's useful, the last successful build was: Jul 13, 2019 4:00:05 AM and then the next build, a few days later, started failing: Jul 16, 2019 4:00:04 AM

 

Bumping; this is still very much an issue for our team. (I've updated the original post with more details.)

 

Case 1172957 -- For what it's worth: I tried submitting our project as part of the bug several times and it failed every single time.

 

@victorw Has that been passed along to the video team?

 

Hi, I am having the same issue today with UCB. I am building an ios app using unity 2018. Theres around 50 small videos that need to be loaded, but some of them keep failing to import, and its different videos each time. The videos are around 500 kb each, so I would be surprised if its a memory issue, but if so, how would I get around this?
Cloud build is downloading these videos before build, and the build completes, but the video files that throw the error arent in the app

[Unity] Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedFailureReason=An unknown error occurred (35), NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x1c7bdf4b0 {Error Domain=NSPOSIXErrorDomain Code=35 "Resource temporarily unavailable"}}

 

We also received some additional information -- this was due to a limitation of 50 mp4s in a project; if you converted everything to webm; the importer is different and should work fine. (If you can't wait for the backport.)
