 I am not saying that there is no issue but I doubt that there is one related to ffmpeg's deinterlacing method. Deinterlacing artefacts are very noticeable and I don't see those with sw decoding and deinterlace. You said that sw decoding with deinterlace does not work at all. I can't confirm this. Can you check this again?  

Just double checked that and in deed sw decoding and 'deinterlacing' work but in my case the picture is not as good as in your screenshot.  

sw deinterlacing should look the same. In order not to compare apples and oranges, can we agree to do all further tests on Linux? Just files, no tv headend.

Please post a screenshot of the same scene. 

Hi, I post it when I get a minute. But having sw deinterlacing is not the point for me. I need hw deinterlacing working properly due to high cpu usage with sw decoding enabled. I just quickly compared hw and sw deinterlacing on linux and sw looks much better than hw but still not perfect.
