BOB deinterlacing flickers after pause

Reported by: steve@… Owned by: danielk

Under Myth 0.19, playing MPEG4 encoded videos on an nVidia MX440.

If the BOB deinterlacer is used then after the video is paused and unpaused the video continues to play but with extensive flickering - looks like it's showing alternately the correct frame and then a very corrupt frame.

I think this is the same problem I am having. I would characterize it as studdering though. For me it happens after a pause or change channel, or rew/ff.

It happens with all drivers I have tried (nvidia 6600), but only on 720x480 resolution. If I use another resolution like 800x600 then it doesn't do this.

However when I use the 800x600 resolution then the xorg process usually sits at about 99% (of one processor core on a pentium D 3.2GHz processor). This only happens with bob deinterlacing. Interesting that it studders a bit at 800x600 but it corrects itself quickly, where it doesn't at 720x480.

So basically I am stuck with using 800x600 for now and just hope my cpu doesn't burn up.

It happens with 0.19 and svn (as of 3-11-06)
