I've pushed a fix for a regression in seeking that seems to fix the
worst of the seeking issues. Editing seems fine here with software
decode and VAAPI direct rendering. VAAPI decode only still gives some
odd seeks for reasons I don't understand. Deinterlacing seems to be
working OK and I can't see/reproduce the blurriness that you mention.
Can you give me details of your decoder/deinterlacer settings?
Apart from the VAAPI decode only anomaly, there is a slight oddity
with 1 second seeking in a PAL recording where it seeks 24 frames
instead of 25. I suspect this is a master issue as well (mythplayer
actually asks to seek 24 frames). NTSC recording (imported) always
Frame by frame seeking in videos (i.e. no seektable) still has issues
when going backwards - again not sure why:)
