|Summary||0000619: Forced deinterlacing video mode or deint=on flag has no effect|
|Description||Forcing deinterlacing (type=video) doesn't seem to work.|
The OSD will say "deinterlacing on" but no deinterlacing is happening.
|Steps To Reproduce||1. Make sure deinterlacing feature in other parts of the playback is disabled, such as in player or decoder for testing purpose (I use LAV and just I set it to always output "progressive" flag).|
2. Open a video which has actual content being (truly) interlaced.
1) Manually turn on deinterlacing using the shortcut (I think the default is ctrl+shift+alt+D) during the playback.
2) or simply add "deint=on" to the filename.
|Additional Information||It *works* for IVTC, however. |
If I put deint=film, or toggle on deinterlacing on and then toggle the type to "film", it can do the IVTC properly on telecined video.

||According to the OSD, deinterlacing seems to be active. Maybe the Nvidia DXVA deinterlacing simply fails to properly deinterlace this video, for some reason? Have you tried multiple different videos?|
Yes, it happens on all the videos.
I should mention that *AUTO* deinterlacing actually works (on this or any interlaced videos, when they have proper interlaced tag), only the forced one doesn't.
i can confirmed this. it's quite odd and needs a change in the lavfilter settings to happen.
take a file that works with deinterlacing out of the box set lavfilter to deinterlacing to disabled (progressive) play the file press control+shift+alt+d for deinterlacing DXVA processing is loaded but doesn't do anything.
Because this bug only happens to forced deinterlacing, not when there is a proper tag from upstream.
Alternatively, you can try with a video that has interlaced content but wrongly encoded/tagged as progressive (the principle is the same.)
