I've been playing with editing/encoding UHD HLG 4:2:2 10-Bit 50fps footage from my Sony FX6 using Davinci Resolve to find a suitable UHD HDR playback format (mostly for JRiver MC). Here is what I've found so far in case anyone else is going down this path:
- Unfortunately, HLG Encoded Videos are not (yet?) supported by madVR at all - HDR (ST2084) HEVC 10-Bit 4:2:0 encoded video revealed weird chroma noise on playback when "Optimize Hardware decoding for performed" (DXVA2-Native) was checked. Turning that off (so it uses D3D11) help a lot with the chroma noise. - HDR (ST2084) HEVC 10-Bit 4:4:4 encoded video looks great .... but.... there does not seem to be HW Acceleration support for HEVC 4:4:4 in LAV (though I see it is supported by the last few generations of nvidia GPUs) so even my OC i9-9900KF flatlines and the GTX3090's decoding cores are at 0%. Nev, any thought on HEVC 10-Bit 4:4:4 HW decoding support (or even if you have heard anything on HLG)? Thanks Nathan |

@jmone
Hardware acceleration for HEVC 10-Bit 4:4:4 is not supported over DXVA2 and D3D11 interfaces. See DXVA Checker for details.

I don't know madshi's plans about HLG support in madVR. Read my thread about HLG https://forum.doom9.org/showthread.php?t=176909 I impressed with MPC Video Renderer (and it let use shaders in i.e. MPC-HC) by Russian developers of MPC-BE player including v0lt and Aleksoid1978 (link on MPC-VR in last my post of that my thread) on my weak computer with Athlon II x3 360 CPU and nVIDIA GTX750v2 on GM206 videocard with 1GB videomemory - it gives ideally fluent 4K H265 4:2:0 50-60Hz video with DXVA native (even ordinary EVR very seldom but stutters not saying about madVR which stutters almost permanent on 4K with its default so very light settings even if vertical frequency GTX750v2's output is equal - i.e. 50(60)Hz - or doubled - i.e. 48 in case of 24Hz(47,952Hz in case of 23,976Hz) - framerate of playing video).

According https://www.ffmpeg.org/index.html#news August 5th, 2019, FFmpeg 4.2 "Ada" almost atop ffmpeg supports 4:4:4 or nevcairiel as usually haven't implement useful for someone option in his LAV Video Decoder? Btw can you upload here (with i.e. postimages.org like I did here ) DXVAChecker4.5.1 or later of yours GTX3090 and on some file exchange server like transfiles.ru 4К HEVC 10-bit 4:4:4 sample?

Lav filters 3d
Posted in Madvr thread and thought maybe here would be good too.
Hello, I've been using lav filters and Madvr for 3d for 4 or 5 years now with no issues. About a week ago, it stopped working. Anyone know anything about this? I've reinstalled madvr and lav and still it doesn't work, when it does flip into 3d, its like the 3d is in slow motion. I thought it might be my hdmi to ethernet converters screwing something up so I connected the computer to my spare projector with straight HDMI and it did the same thing. I thought it was one specific file as we had literally watched 3d the day before and then realized it was all of them. Anyone have any ideas? I'm thinking a windows 10 update maybe or something broke it. Its a windows 10 machine with I3 processor Skylake with internal intel graphics. |

@VictorLS
- Original Sample is here : https://behome.dyndns.info/index.php/s/4rYP8bqs4yaRd5p - This thread has a Screen Shot showing the Chroma Noise Issue : https://yabb.jriver.com/interact/ind...html#msg889524 - I tried all the LAV Decoding Option including CUVID - I tried using the MPC Video Renderer but could not successfully build a graph in JRiver Media Center (which I use) so I can't comment Another option that I found that "could" work is that if I encode my video as HDR-PQ UHD 10-Bit 4:2:2 AVC All I then it will playback on PC's with a good CPU (i7/i9) for SW Decoding, and GPU for the madVR HDR part. Downsides are: - my HTPC are i5-7500 and they do (mostly) play these files without dropping frames (mostly) but the CPU is at 100% and the 1660Ti have to use Dumb Mode for HDR - They are slow to render out of Resolve (half real time), and the files are very large @ 5GB per minute, and still in the MKF wrapper with multiple mono tracks requiring a ffmpeg remux (at least that is pretty fast). I guess I could also do a 2nd pass encode to drop the bitrate with ffmpeg.... but it is all getting a bit to irritating of a workflow + I'd need to upgrade the CPU in my HTPCs to avoid decoding performance issues. |

I have an audio splitter question: there's this option "Prefer audio stream with highest quality".
The problem is (let's say the file has 2 audio track: DD ger [default], DTS-HDMA eng) if there's an audio track with default track, then that one will be used (DD ger tack). So, is there any rules I can use for audio with which I can force to select the highest quality in this case as well (without specifying the language)? Thanks

Despite you haven't upload screenshot of DXVA Checker 4.5.1 of your 3090 (and your recoded with some software (?) sample) I asked in my previous post try recoded your FX6 Sample.MXF in HEVC 4:4:4 FX6_Sample.mp4 (2,1 MB - so about 500 time smaller than original) https://yadi.sk/i/BqcTHKuM9dYM2g with CUVID and others. Despite it isn't loseless it'll may be hadware accelerated. Quote:
What command-line do you use for remux to get output with one (or several) audio track(s)? PS. Did you try other than LAV Video Decoder like MainConcept (Demo) AVC/H.264 Video Decoder with turned off hardware acceleration in first string of its settings? I.e. my weak Athlon II x3 360 can't decode all 25 fps with LAV Video Decoder of this 20171205-014323_4KUA.ts (73 MB) https://yadi.sk/d/AnnpTSYKkoNkUg sample recorded by me from SAT but with MainConcept (Demo) HEVC Video Decoder despite of about 95% load of each of three core. PPS. While Turing can HW decode in the centre of article https://developer.nvidia.com/blog/nv...ture-in-depth/ HEVC YUV444 10/12b HDR at 30 fps, H.264 8K, and VP9 10/12b HDR, I've uploaded FX6_Sample_25fps.mp4 (1,9 MB) https://yadi.sk/i/61fKGLxWBoUIyA if Ampere still the same as Turing in HEVC 4:4:4 and can't hardware decode 50-60fps at all.
