It probably won't solve the issue, but maybe you could try using
avcodec-54.dll since it's the latest release? Or is there a reason why
you need the older one?

The same video that could be played with 1 frame latency now has a 100+
Have you tried other h264 files? Other formats?
If it's specific to a file or to a set of files coming form the same
encoder, maybe it's because of a header value that isn't standard: I
would then recommend checking the patch notes between the 2 releases to
know what could have changed.
Also, are all the frames returned, simply really late? I'm wondering if
you're maybe missing a lot of frames and it isn't a latency issue at all.
Hope it helps a bit,
