So, it's fine for you?
Btw: Are you using LAV splitter? It reports 59.94 fps but maybe your video has exactly 60 fps. This is fixed in the nightlies. If it's not related to FSE switch or normal issues in the beginning, it could be a glitch in the video itself. I have such a sample with lots of glitches. |

The 720p file is 59.94, it's an ATSC TV recording. |

My 720p60 testclip was this: http://www.tomguilmette.com/wp/download/8/ [ downloaded from http://www.tomguilmette.com/wp/my-blog/archives/2500 ]. Can you check that with your configuration? So, if I understand right, you are saying on the whole that you have had better luck with using madVR on i7-3770K compared to Hendrik and me... |

And I can't play yet with my chosen madVR settings since I'm still waiting for my favorite shops to get the 3770k in stock. sigh.

The difference seems to be the decoder used. Using QuickSync, the GPU is overloaded with 720p60, because it puts some extra strain on the GPU. With software decoding, the situation improves.
Still leaves the problem with my black levels The desktop looks stupid with limited range.

On a separate note, do you guys observe any difference when the amount of DRAM devoted to the iGPU is varied in the BIOS? |

However, a 3770 can process a 1080p or 720p file very easily. Also need to check the performance state of the CPU, in QS mode my 2600k will stay in its lowest clock state, while SW decoding actually causes it to go to max speed. Didn't check IVB. Anyway, more tests when i have the time.

Or take a laptop with hd4000 iGPU and with a 1280*720 display (or other non FullHD display with the desktop machine): how well a 1080p24fps and a 1080p30fps will be played? (I even don't write down the last option in this row ... )

that should be even harder to do.
i'd like to see more how ram and gpu core overclocking play into this. also, you can always lower chroma to bilinear, that isn't that big of a deal imo, and that should provide a big performance boost. |

Its been a while, but i have a fresh test build:
x86: http://files.1f0.de/lavf/LAVFilters-...0-ga4c4634.zip x64: http://files.1f0.de/lavf/LAVFilters-...4c4634-x64.zip Not really anything big and note-worthy, its just been so long since the last release and so much has changed in ffmpeg that i feel like its better to post it here before tagging a release. So, if you want, test away, and report any "new" problems! Especially MKV has changed a bit, to avoid some issues i had to re-structure how the code is integrated. Hopefully, no visible changes at all (or well, maybe a crash less in some crazy circumstances!)

technically its one before that, but the commit has no real influence.

Hendrik,
Does the new release remove the max. 1080p limitation for DXVA2 / QS decode in LAV Video Decoder ? (the one that Andrew fixed locally to test out 4K acceleration in his review at Missing Remote) Thanks! |

Like i explained numerous times before, the auto-detection of 4k hardware support is not working properly (yet), so i blacklisted it. However, i only did so for DXVA2 Native. QS has no such artificial limitation. If 4K decoding does not work (it doesn't for me), its most likely your driver being bad (or go blame egur)

0.50.1-50-ga4c4634.zip 0.50.1 is the last release 50 is the number of commits since then. a4c4634 is the hash of the commit. Dunno why they put a "g" before the hash, i just use "git describe" to name the files.
