Having the same issue on iOS 15.4. Tried several changes in the videoMaxBitRate, videoBitRate, videoFrameRate, videoMaxKeyframeInterval but nothing seems to work. Any help would be greatly appreciated.

I found the solution, below is the fix for iOS 14.5 for those who need it.

Open file LFHardwareVideoEncoder, search function resetCompressionSession then change kVTCompressionPropertyKey_AllowFrameReordering to

if([[UIDevice currentDevice].systemVersion floatValue] >= 15.4f){ VTSessionSetProperty(compressionSession, kVTCompressionPropertyKey_AllowFrameReordering, kCFBooleanFalse); } else { VTSessionSetProperty(compressionSession, kVTCompressionPropertyKey_AllowFrameReordering, kCFBooleanTrue); }

It will work. Good luck

@noho501 If I added this changes in LFHardwareVideoEncoder.m file then water mark view is not visible to viewers. Is there any solution for this ?
