I have tried connecting LAV Video Decoder to Ffdshow Raw Video filter, but it doesn't seem to interpret 3D as anything other than 1920x1080 24fps video. Are there any other readily available directshow filters that can take the 3D output from LAV and simply interleave or even just stack it into a 1920x2160 window for display on a 4k passive 3D TV? |

Its a special format for 3D videos that contains both views separately, and a filter would have to be specifically adapted to support it. Nothing like that exists.

On a separate issue, I have noticed that LAV Video Decoder has undefeatable dithering with only the option to select ordered or random. Since MadVR has its own more advanced options for dithering, is it possible to disable LAV's dithering as I wouldn't think dithering an already dithered source would be desirable? |

lavfilter output is bit perfect if possible.
if that is not the case and bit perfect output is impossible than it may use dither for conversation. dithering is for example used in RGB output with YCbCr source but as long as you are not outputting RGB with lavfilter it is not doing that. |

Because it is mainly a container format. The contained video appears to be similar to MotionJPEG.

Not every minor format got a option, which means you just can't turn it off, but it still works.

If you use madVR and don't mess with LAVs output format settings, then it'll generally never dither, since it can output bit-exact images.

If you want to be pedantic, sending 1920x2160 (line interleaved 3D) to a window on the display will not provide the proper aspect ratio and retain the 3D nature of the source, but then neither does sending 3840x2160 because the window frame makes scaling necessary which undoes the line interleaved 3D registration anyway. The only way to properly view such 3D is in fullscreen mode. I have only mentioned 1920x2160 because that is the bound of the data when you interleave the left and right eye 1920x1080 views. If you could see your way to providing a 4k 3D option that simply interleaves the unmodified left and right eye views (or stacks them horizontally or vertically depending on output mode) and utilises fullscreen scaling to create the proper aspect ratio, those of us with 4k passive 3D displays would be appreciative. Since processing is minimal, it should also lower display render times. Last edited by IanD; 13th May 2017 at 07:57. |

Hey nevcairiel,
I've been looking through the list of supported types in the splitter and testing some file types located at the ffmpeg archive. I've been having trouble getting the following types to play: Yamaha SMAF - http://samples.ffmpeg.org/A-codecs/suite/MMF/ - will not play; is listed in LAV splitter Also, the following types appear to be working in the splitter but, like ROQ before it was fixed, they all seem to have a standard codec that is used which is NOT supported in LAV: Microsoft XMV - http://samples.ffmpeg.org/game-formats/xmv/ - the audio plays but the video codec for all the files has the FOURCC of 2VMW which will not play. Commodore CDXL Video - http://samples.ffmpeg.org/game-formats/cdxl/ - audio plays but the CDXL video does not. Is it possible to add support? Wing Commander III Movie - http://samples.ffmpeg.org/game-formats/wc3-mve/ - audio plays but FOURCC WC3V does not appear to be supported. Is it possible to add these? |

Support request - #13
to nevcairiel:
Problem with LAV Splitter Source. I have error message: E_FAIL (0x80004005) in GraphEdit if playback this MP3-file that have built in chapters(like in .CUE-files) as live-stream: http://www.electromixes.com/zik/electromix_v118.mp3 p.s. If i use "FileSource(URL)+LAVSpltter" i didn't have such problem. Any feedback would be appreciated. Last edited by max79; 17th May 2017 at 14:28. |

it expects two streams, but LAV gives one... can you just split it in two streams? Option maybe? also there is no 3D at all in new versions (from LAVFilters-0.69-45-av1_test30-git-r3851) LAVFilters-0.69-av1_test15-git-r3806(42b9649) LAVFilters-0.69-76-av1_test31-git-r3882(f72d508) Last edited by Artofeel; 19th May 2017 at 11:52. |

I do not plan to offer alternate 3D transport modes, using 2 streams is inherently inferior since it requires manual synchronization, instead of just getting both views in one stream. Also, I cannot offer any support for modified custom builds.

I'm not spending my little time on trolling the web for any changes someone made without the slightest attempt of submitting them to me. But since you mentioned this set specifically I looked it up, and not one of the patches in there is something I would apply without serious questioning.

I an using latest nightly.
In hdr files using cuvid madvr says unknown properties with reagrd to hdr. With dxva it corectly converts the content.

CUVID doesn't support a bunch of things, including HDR metadata, and thats unlikely to change, since the NVIDIA API doesn't export that data. I have said this in the past - DXVA2 Copy-Back should generally be preferred over CUVID.

anyway what this format IS, name? it's not field\frame separated, so then how? and it's normal that LAV doesn't play Subset MVC (MEDIASUBTYPE_EMVC) ? it's listed here but it's not working https://github.com/Nevcairiel/LAVFil...es/moreuuids.h *using latest nightly build |
