Guys using the latest nightly LAV Splitter/Video/Audio, I have seen an issue (not specific to this LAV version) with "The World Is Not Enough" Blu-ray. When I play the index.bdmv or the largest m2ts file, when I seek a significant way into the file, the player freezes for possibly a minute. I assume this is the fact that the file has been created without something like keyframes or something like that? Do you know if this is something LAV is behaving correctly with (ie taking this amount of time) or is there a way to make it faster without changing the actual files?

If the video stream did not have regular frequent keyframes, it would not be Blu-ray compliant and should have been rejected by any serious authoring tool... I would rather wonder about issues with the logical structure. But that's harder to prove.

I have a problem playing some avi files.
File source splitter perfectly adds a LAV video decoder if used in MPC/graphstudio but the LAV splitter does not add that automatically. If LAV video decoder is added manually it plays perfectly. Mediainfo of video: Code:
General Complete name : <redacted>.avi Format : AVI Format/Info : Audio Video Interleave File size : 24.8 MiB Duration : 1 min 50 s Overall bit rate : 1 895 kb/s Writing library : VirtualDub build 16250/release Video ID : 0 Format : Indeo 4 Codec ID : IV50 Codec ID/Info : Intel Indeo Video 5.0 Wavelet Duration : 1 min 50 s Bit rate : 1 800 kb/s Width : 320 pixels Height : 240 pixels Display aspect ratio : 4:3 Frame rate : 15.000 FPS Bits/(Pixel*Frame) : 1.563 Stream size : 23.6 MiB (95%) Audio ID : 1 Format : PCM Format settings : Unsigned Codec ID : 1 Duration : 1 min 49 s Bit rate mode : Constant Bit rate : 88.2 kb/s Channel(s) : 1 channel Sampling rate : 11.024 kHz Bit depth : 8 bits Stream size : 1.16 MiB (5%) Alignment : Aligned on interleaves Interleave, duration : 67 ms (1.00 video frame) Interleave, preload duration : 500 ms The indeo format is checked in the video formats configuration Version is 0.74.1 |

Hi all,
I have an issue with some old IV50 AVI files. If I open them in MPC they play fine, with a generic filesource -> LAV video decoder and LAV audio decoder. When opening them in graphstudio, LAV splitter is used, LAV audio decoder is added, but no video decoder. Manually adding LAV Video decoder and connecting it to the splitter, playback is ok. Mediainfo of this file: Code:
General Complete name : <redacted>.avi Format : AVI Format/Info : Audio Video Interleave File size : 24.8 MiB Duration : 1 min 50 s Overall bit rate : 1 895 kb/s Writing library : VirtualDub build 16250/release Video ID : 0 Format : Indeo 4 Codec ID : IV50 Codec ID/Info : Intel Indeo Video 5.0 Wavelet Duration : 1 min 50 s Bit rate : 1 800 kb/s Width : 320 pixels Height : 240 pixels Display aspect ratio : 4:3 Frame rate : 15.000 FPS Bits/(Pixel*Frame) : 1.563 Stream size : 23.6 MiB (95%) Audio ID : 1 Format : PCM Format settings : Unsigned Codec ID : 1 Duration : 1 min 49 s Bit rate mode : Constant Bit rate : 88.2 kb/s Channel(s) : 1 channel Sampling rate : 11.024 kHz Bit depth : 8 bits Stream size : 1.16 MiB (5%) Alignment : Aligned on interleaves Interleave, duration : 67 ms (1.00 video frame) Interleave, preload duration : 500 ms Anyone able to shed a light on this? |

Hi
maybe someone can help me yestrerday i got a rx5700 xt I see that with the internal win10 videoplayer files are correctly deinterlaced, all the other player that uses lav have broken DXVA deinterlacing, if i use copyback + software deint it works., at the start i thought it was Madvr but even with EVR it's the same ..... anyone have similar experience with that card ? I noticed that before with rx460 i had more option under driver video custom setting, now there is only brightness. Already tried with DDU to reset drivers thank you fro any help |

Could you try with MPC Video Renderer? https://github.com/Aleksoid1978/VideoRenderer
I've read huhn say in the past that it supports D3D11 video processing, so if you set LAV to D3D11 native decoding it could work. If it does then it looks like AMD didn't bother testing backward compatibility with DXVA2.

No, cropping is not supported, unless its on a codec level.

Just I'm not sure that this renderer uses Hw deinterlacing (even if using dxva native should the only way to deinterlace is by HW). Looks like the problem is in EVR and Madvr implementation

mpcVR can deint with d3d11.
hardware deint is generally broken on NAVI this is nothing new. in best cases it uses bilinear which is not a deint algo that should ever be used or it is combing. i mean: https://abload.de/img/amddeint2mji2.jpg what so ever lavfilter has nothing todo with this. |

Hi nevcairiel.
With the new Matroska spec (though it's not implemented in FFmpeg, the code from Plex's patches is available), Dolby Vision metadata can be inserted and decoded from MKV headers. Would it be possible to parse the HEVC RPU NAL units and make that information available to the renderer (for example, madVR) through the LAV decoder? HW acceleration might cause issues, though. I have working code to parse this RPU data (at least for profile 7 files), but I'm not sure if it's feasible for that metadata to be useful. I think it would be nice if the renderer could have access to pre defined per-frame information about min, max, average luminance and etc. Just wondering if it's something that would be possible, because I'd be interested in helping to add support.

Sound good quetvoid, thanks, hopefully you can some magic together

It seems AC-4 playing still possible with a fork only but what about Dolby E? In Sample Eurovision 2019 Tel Aviv.ts (154 MB) https://yadi.sk/i/j1zj1sqy2myOfw third (Dolby E) audio track plays like loud noise - that patch https://patchwork.ffmpeg.org/project...ier@cji.paris/ may helps to add Dolby E support in LAV Audio Decoder with adding all possible metadatas described in former NDA's document.

Any support for new formats is always nice, but it's not really essential for LAV: Dolby E is a studio format for production, it's not supposed to be broadcast to end users. Just like 4:2:2 or 4:4:4 video isn't either. I'm amazed at how you keep "finding" weird streams like that.

I'm just SAT-amateur
Btw I haven't seen 4:4:4 from SAT yet (but hardware acceleration supported by nVIDIA's Turing and Ampere) and I often see 4:2:2 from more than 10 years ago but only newest Intel's GPUs (inside of CPU Tiger Lake or discrete videocard Xe) seems will support it. |

In registry (appears when although any parameter of LAV Filters' properties is changed once tough) - it's same for x86 and x64 version of LAV Filters so it hurts me sometimes when I need separate (i.e. CUVID Hardware acceleration for x86 in my favorite old version of KMPlayer not supported DXVA2 acceleration with LAV Video Decoder - with other decoders DXVA2 works in that version of KMPlayer just fine and DXVA2 (native) acceleration for x64 in app SmartDVBx64 for HLGtoSDR transformation in EVR-CP to watch HLG programs with ~right colors directly from SATs): [HKEY_CURRENT_USER\Software\LAV\Audio] for LAV Audio Decoder [HKEY_CURRENT_USER\Software\LAV\Splitter] for LAV Splitter and finally [HKEY_CURRENT_USER\Software\LAV\Video] for LAV Video Decoder where I proposed to add key for skipping frames feature http://forum.doom9.org/showthread.ph...04#post1902404 for live software decoding hard streams (like 8K, 4:2:2 etc) on weak processors with well audio.

I agree and I hope this document https://developer.dolby.com/globalas...escription.pdf with patch https://patchwork.ffmpeg.org/project...ier@cji.paris/ will help to implement full Dolby E support in LAV Audio Decoder and it'll be very useful for SAT receiving.
