SUPPORT REQUEST - #36

@Nevcairiel
Starting from LAVSplitter_v0.74.1-34 i got issues after seeking to the beginning on HLS VideosOnDemand, now playback is starting but in fact, frames are output that do not correspond to the beginning position, but those that were at the time that was before the rewind to the beginning. On v0.74.1-32 and older LAV version I have differ behavior, it just didn't start to play media(i didn't hear sound and see only one frame that were at the time that was before the rewind to the beginning. And I liked this behavior better), example:
http://demo.unified-streaming.com/vi...m/machete.m3u8

Seems it looks like something similar with the problem here:
https://github.com/Nevcairiel/LAVFilters/issues/306

Any feedback would be appreciated.

UPDATE: Fixed in v0.74.1-98 and newer!

Reverting 9fbf56d does fix that seek issue.

There is a reason for this check. Reverting it just breaks other cases to fix one thing, instead of investigating why it fails. Which case is more important, the one the complained the most recent?

The latest version of MPC-HC (1.9.10) includes a current build of LAV. Also, most of the codec packs (like K-Lite) do their own builds from the nightlies. Or you can build your own, of course.

It seems to have a decent improvement in seeking performance, but there's no deinterlacing anymore. madVR wouldn't deinterlace with dxva11 it seems. Why?

And LAV is only ever willing to use HW deinterlacing with CUVID, and won't use software deinterlacing. Super annoying that deinterlacing is always a problem with LAV+madVR.

madshi didn't implement it. Probably considered not high priority.
I would like D3D11 deinterlace with NVIDIA but then D3D11 decode causes many issues in MediaPortal so would mean even more debug.

I am a MPC-BE user and do not want to install a codecpack on my system. Compiling myself is to high for me.
I am only a video guy, not a programming guy

@nevcairiel:
I beg on my knees for a nightly build Please Nev

Which variant of MPC? Can it be installed system-wide? (provided any app can even use it.)

Edit:
Never mind. I found it on github as a separate filter. It doesn't work with the tuner app though, and only there I have interlaced video. Out of curiosity had a look at it in PotPlayer. The output became too dark with a lot of detail swallowed.

The latest release build of MPCVR is a bit buggy. Try with the nightly build:

Works identically. With "Use Directx 11" it produces abnormally dark picture.

Press Ctrl+J to show the renderer debug/statistics overlay and make a screenshot. Post that in the MPC-BE topic so that the developers can have a look at it.

To use MPCVR you need to uncheck the 3 boxes in its settings.
Use for [NV12] [P010/P016] [Other supported formats]

its a bit convoluted.

I've fixed the issue that prevented nightlys from being uploaded and future changes should hopefully result in new nightlys once again

I'm also planning on a release version in March.
