Hard stutter on certain HTML animations

I updated CEF to 142 yesterday, and it looks like the stutter issue has gone away.

Could some of you who have had this issue give it a quick test to confirm?

If that is the case, that is the last thing I had on my list to do before 2.5. So I can get it released (be aware there are a couple of changes in master which are being held back for 2.6, but you are unlikely to be using those)

I can confirm that my HTML animation and the Singular.live test page are both running smoothly on the latest master build, eeeda4.

Thank you, Julusian.

I also can confirm, that my html animations runs perfect smoothly now.

Many Thanks, Julusian!

But there is a new issue in 2.5. (build windows from 2025/12/03)

After sending the command

PLAY 4-200 decklink device 6

Casparcg starts spewing this messages approx. 9 times per second:

[2025-12-06 23:04:32.629] [info] DeckLink Duo 2 [6|1080i5000] Input format changed from 1080i5000 to 1080i5000

I have Blackmagic drivers 14.5, two Decklink duo cards.

In 2.4.2 this command works correctly without any warning, casparcg.config files are identical in both versions.

In recent versions I always need to state the input format when adding a decklink, otherwise sometimes it doesn’t work.

PLAY 4-200 decklink device 6 FORMAT 1080i5000

I don’t know if it will help with your issue.

Hi.

Thank You. It works!

My recent version was 2.4.2 ans there was not necessarily to add the format
