For a moment i thought you already did that, but now i see only Bink Audio and the Container format are known so far. Oops, right.

(that one is using bink video not interplay mve). Hey, can you do the same feat with Icewind Dale 2? (that one is using bink video not interplay mve).

Even the ones that are 24fps. Those would have a 20% lower bitrate than I ask for, except that ffmpeg duplicates frames, so I instead get the right bitrate but stuttering. If I override framerate with "-r" then both the actual number of frames encoded and the framerate reported to x264 match that new value. I don't see 90000 of anything in mpeg.

Those would have a 20% lower bitrate than I ask for, except that ffmpeg duplicates frames, so I instead get the right bitrate but stuttering. If I override framerate with “-r” then both the actual number of frames encoded and the framerate reported to x264 match that new value.

Alas, if I understood MPEG better, this would probably be obvious to me. It should be possible to fix the Interplay MVE demuxer to output a more responsible framerate. It will require a little refactoring, though. The part I don’t understand is that, since the 90 kHz thing is an MPEG mainstay, what happens when feeding MPEG files into x264?

Looks to me like your demuxer is actually fine (though maybe a bit ugly), looks to me like the bug is that libx264 seems to assume that the time base is the frame rate - the actual frame rate is not available via the FFmpeg API, AFAIK...

I'm sure Michael will complain about not fixing it properly but at least it should work ;-) Can’t you just hack your demuxer to set time_base to 1/90000 to get the old behaviour again?
