Just encoded two movies (The Corruptor and Der Schweigende Stern, both PAL 25fps) with my usual GKnot/xvid HeadAC3he/ogg -> ogm method.
But to my surprise both were out of sync. Perfectly synced in the beginning but about 1-2 seconds out of sync in the end. This has never happened to me before so I tried HeadAC3he/MP3. Same result. So it's not a problem with the latest vorbis.dll, the OggDS filters or the streamformat (avi or ogm).
After some further muxing and reencoding I think I found the guilty: the latest SMP-capable ssrc.dll seems to have some issues with downsampling to 44.1kHz (at least on a dual-XP1800+).I don't know if it's the Athlons or the SMP or both that causes this.
I reinstalled the complete HeadAC3he archive available at Doom9.org and everything is perfectly in sync again. Can ne1 confirm this?!
P.S.: Oh, the filesize of the Corruptor's audiotrack using the latest (faulty?!) ssrc.dll was 88,8MB while the older ssrc.dll produced 83,5MB so it seems it inserts some samples too many in the stream.
