ffdshow - bobbing or doubling framerate doesn't work

[Sp00kyFox]

hi dudes,
got some problems with ffshow. I wanna watch a video pal dvd wich is interlaced. At first I wanted to deinterlace it with pure video but since ffdshow doesn't support DXVA I tried to deinterlace it with one of the filters of ffdshow. The filter wich are leaving the framerate constant are working nice but the framerate doubler and the bob filters have a problem.. they don't double the framerate like I think it should be. Also the osd tells me that the framerate (25fps) doesn't changed. Anyone knows how to fix that problem?

renderer: overlay mixer
dvd decoder: nvidia dvd decoder
media player: zoom player
additional filters: ffdshow raw video processor
ffdshow version: rev 1920 sse

Well, I'm pretty sure I watched 4 episodes of Battlestar Galactica using ffdshow for DVD decoding and LeakKernelBob to deinterlace yesterday, and I'm pretty sure it worked... :)

Anyway, the only OSD option to display FPS is "Movie FPS", and that always displays the input FPS, since after decoding you have a bunch of frames with timestamps instead of an FPS value...

Try turning on the "Frame duration" OSD line and check if activating one of the bobbers halves the frame duration like it should.

Also, I guess Zoom Player has it's own playback statistics; have you looked there for a FPS value?

(Also, if it doesn't work with the nVidia decoder - have you tried using ffdshow (with libmpeg2) for DVD decoding instead? But I just tested using MPC's built in MPEG4 decoder on a video I have here in conjunction with the raw video filter and bobbing worked just fine...)

ah ok thx dude... my failure :(
Checked some wrong setting so it looked like to me that the framerate doesn't changed.. also the osd confused me. Now it works fine :thanks:
