| 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. 3. Either: 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.) |
