    Thank you Max. mixerTest.sh also has the same result (500). It's hard to check now, but it was normal in version 5.2.458 before the update. (Recently used yesterday) We just sent a full report to support@flashphoner.com. Thank you.

    How to get clean video in the mixer.

    Hi Max. Yes. Recording samples have time differences. (However, the symptoms are always the same. The larger the image change, the easier it is to reproduce.) Wow~ mixer optimization is the best gift for me. - I will adjust the value of "custom lossless video processor". - OBS KeyFrame was set...

    mixer drop frame

    Dear Max. You are right. Using obs to lower the setting of one of the publish streams (resolution, bitrate) has greatly improved the symptoms. The cpu usage is stable and no unnecessary server logs are shown. There was not enough media traffic for the stream mixer. Attached video is 6 stream...
