No, because vertical sharpness and fluent playing will be lost. I want get from ZEE TV example 720x576p50 without flickers - maximum quality on PC as on TVsets.

Sorry, I got confused by you even mentioning "half vertical resolution" at all. Now that I see the sample video, I understand the issue: This video has been encoded with fields like frames, but they are not handled like fields of interlaced video, instead like completely separate frames.

H.265 should be broadcasted as progressive content only. The original specs did not even mention interlacing, I believe to remember ... HEVC wanted to make it obsolete. Some encoders may still create "interlaced HEVC" treating fields separately. But these fields should still be organized as pairs making a whole frame. This is not the case in your sample. It looks like a result of AviSynth's SeparateFields() function.

Decoders like LAV Filters don't recognize these frames as pairs of fields, so they won't offer a weave feature. This may require to process the video separately in e.g. AviSynth with Weave(), and then you should not re-encode the result as HEVC (H.265), instead as interlaced AVC (H.264) – if it is truly interlaced at all (I did not check that).
_

Remark: 720 lines is still HD. SD is only up to 576 lines (conventional PAL).

You're quite right.
About 720 lines - if you read more carefully I meant not lines but columns
Most of PAL channels has 720 horizontal resolution but I saw 768 and 544 to (anamorph or non-square pixels).
Writing must be such Force weave option I meaning ~ AviSynth with Weave() but I want still have hardware acceleration of such files. I think one of the possible ways to get what I want is add ffdshow raw filter between decoder and renderer? Or may be nevcairiel just add one more Deinterlacing mode in LAV Video Decoder...

The number of pixels per line is not really helpful. Depending on the aspect ratio common for the medium (e.g. DVD, SVCD, DVB, or deskewed), you can have PAL with 576 lines and 352 / 480 / 544 / 704 / 720 and even 768 or 1024 pixels. But you always need 576 lines for PAL, it might be interlaced.

Deinterlacing options will process pairs of fields to make frames. But it will not process pairs of frames.

the file is 50 FPS it can't be interlanced there is no spec for it.
an intelranced file needs 30 or 25 frames per sec.

and the file is progressive flagged anyway a deintelrancer has nothing todo with it.
and the file reports a AR of 40/11.

so the file is incorrectly encoded
or the file is incorrectly stored in the container.

using WAEVE() turns an progressive file into an interlanced file why should lavfilter ever do this even more important why should an interlancer be added as an deinterlancer...

You just need to use Avisynth/Vapoursynth/Virtualdub2 to re-encode this horribly butchered encode. No one is going to add support for this. I have no idea why they didn't just use H.264 if they wanted interlaced; it would probably have been more efficient with MBAFF anyway.

HEVC specs do allow interlacing. But AFAIK LAV+MPC-HC don't support it correctly. (Irregardless of whether or not his file is or isn't violating specs.)

There is a ticket on the FFmpeg bug tracker about such HEVC files:

The NVIDIA driver contrains profiles for various games/apps that specify which GPU is used. You can use NVIDIA Profile Inspector to customize/add profiles.

lovely is doesn't output 25 fps frames per sec with that it would be ok because the last step of decding is skipped?

and i just said there is no spec for 50 FPS 100 fields yet and hopefully never will be.

I didn't say about 100 fields - I said about 50 full frames which must be get from "50 half vertical resolution frames" = "50 progressive fields" with same deinterlacing method like ordinary (352,480,544,704,720,768,1024)x576i50fields SD TV video from SAT

sorry but i'm not going to discuss the basics of interlancing here. progressive fields...

the file is wrongly decoded or still wrongly created.
it may get fix for software decoding but for hardware decoder not sure if anyone else than the GPU producer can fix this mess.
i there even a spec for hardware interlanced HEVC decoding?

is NO, there isn't so SAT provider has to translate interlaced SD and FullHD video as serial "progressive half vertical resolution frames"=fields. And several people has modern TVset with internal SAT tuners (even with CI+) said all good with channels h265 like ZEE TV but nobody said PC plays that file well (with solid circle around ZEE TV logo) even if aspect ratio is right = 4:3...Why computer worse than TVsets?

SAT provider can translate interlaced SD and FullHD (fields) to HEVC (frames) by using a (good) deinterlacing filter.
"Reverse Deinterlacing" for "bad" deinterlacing" by Sat providers is not supported by GPU's nor LAV software.

I agree - i.e. Vector Adaptive Deinterlacer - it's best way but one SAT provider decided to put more channels in one transponder, so we must to work with it as is...

LAV video decoder bug.
Please fix it!
With UHD AVC, neither iGPU or nvidia GPU decoding works with any of the methods.

But with UHD HEVC (4k bluray) everything works.

Optimus is broken in general. Doesn't even work with RemoteFX in Hyper-V. The whole idea of rendering on a separate gpu, then passing the data to the iGPU is disgusting.

Good developers have no problems.
All players works, madVR works (window and exclusive mode), PotPlayer internal D3D11 decoder works, only LAV Filters fail.

I have no interest in supporting Optimus. Feel free to contribute patches if you think it's so easy and have access to such hardware.
