Video processing times out on videos where 0 frames were written

Current behavior

Happens in our kitchensink tests for any video that is less than 3 seconds long: https://app.circleci.com/pipelines/github/cypress-io/cypress-example-kitchensink/1063/workflows/081e2595-85f7-4cc9-a5f7-fa3f23006b8e/jobs/6905

Also may be the issue with our desktop-gui-component-tests for app/nav_spec.jsx where the test runs for 0 seconds.

CircleCI failure: https://app.circleci.com/pipelines/github/cypress-io/cypress/20691/workflows/a3b97c80-6b4e-4697-b047-bbaf32471656/jobs/750928

With verbose video frame logging, you can see before the error throws that there were 0 video frames written.

Seems to be isolated to running on Mac in our CI, even though the Mac version is 10.15.7, which I can’t recreate running locally on the same OSX.

@flotwig thoughts:

i think the issue is that it’s simply not getting enough frames still. flaky recurrence of the bug we thought we solved with this recursive stuff. i would try bumping waitForMoreChunksTimeout first, and then try bumping line 119 to expect writtenChunksCount to be bigger

…or some other form of increasing the frames.

  cypress-verbose:server:video:frames frames written: 0 +13s
Warning: We failed processing this video.

This error will not alter the exit code.

I am fairly confident in saying that this has been resolved. I’m going to close this; If we see fresh instances, I’d suggest a new ticket with a more recent example.

https://app.circleci.com/pipelines/github/cypress-io/cypress/31138/workflows/70a8e975-295d-4ab9-80f9-d5c1f41fc74b/jobs/1215113 is an example of a recent run of the kitchen sink on mac. The task contains multiple spec files that complete in under a second, and video processing has succeeded consistently. I’ve checked the last half dozen runs, no video encoding failures.

Video does fail in Firefox, but that’s a known and unrelated issue.
