[Libav-user] Syncing multiple sources.

Hi Carl,

> But the setpts filter is changing the framerate to 60 fps, no?

I am pretty sure it does not, it changes the timebase in use. In a stream
with 1/30 tb and pts values [0,1,2,3,4,5], using a 1/60 tb those pts values
would change to [0,2,4,6,8,10].

> WMP only supports yuv420p, this is not related to cfr vs vfr. (A former
developer decided the the warning is not needed.)

Oh, I wasn't aware of WMP having that limitation.

example to show a timing issue.

Maybe you can suggest some muxer format that supports vfr.

Thanks.
