FreeSteamCoder v2.80 lip sync

Post by G3GJA » Tue Jul 05, 2022 11:56 am

I have just upgraded to an RTX A2000 graphics card and switched the FreeStreamCoder to use nVidia hardware acceleration for the encoding instead of the Intel GPU built into the processor.

Used with OBS, FreeStreamCoder now easily copes with H265 with no stuttering. Maybe the A2000's B frame capability helps.

However, the lip sync is awful. The audio lags behind the video by at least a full second.

I've looked at the Easy DATV software, that does have a lip sync adjustment, but so far I've not found a way to make it work with my Portsdown 4 using IPTS in.

Anyone got a suggestion that might fix this?
