[mythtv-users] 0.24 VDPAU Judder or Jumpiness With Interlaced Telecined Content

[Mark Goldberg]

I upgraded to 0.24 from 0.23 and it seems that VDPAU playback results
in judder or jumpiness with
1080i 29.97 interlaced telecined content. Log excerpts are below. More
info can be provided if necessary.

With 0.23 the log had this:

2010-08-06 22:57:27.226 VDP: Accepting: cmp(> 0 0) dec(vdpau) cpus(2)
rend(vdpau) osd(vdpau) osdfade(enabled)
deint(vdpauadvanceddoublerate,vdpauadvanced)
filt(vdpauivtc,vdpaucolorspace=auto)
2010-08-06 22:57:27.263 VidOutVDPAU: Enabling VDPAU inverse telecine

2010-08-06 22:57:27.412 Enabled deinterlacing

and things looked fine. Now, with the same profile, it gets

2010-11-23 13:29:27.971 VDP: Accepting: cmp(> 0 0) dec(vdpau) cpus(2)
skiploop(enabled) rend(vdpau) osd(vdpau) osdfade(enabled)

2010-11-23 13:29:28.237 Player(a): Enabled deinterlacing

and it is jumpy.

I disabled the dblocking filter and it gets

2010-11-23 13:55:15.913 VDP: Accepting: cmp(> 0 0) dec(vdpau) cpus(2)
skiploop(disabled) rend(vdpau) osd(vdpau) osdfade(enabled)

2010-11-23 13:55:16.170 Player(b): Enabled deinterlacing

and it is not jumpy. I'm not sure disabling the filter makes it look
worse or not.

Any ideas?
