(quoting here since I don't think it's related to HEVC in mkv specifically)

I amended my post slightly to express the dependency on sample complexity

Hopefully not-so-OT , but now the evil Strongene Lentoid Decoder is compatible with the MKV and MP4 demuxers of LAV Splitter, and besides, now it (finally) can be used in Graphstudio's performance test as well

I think that decoder is H.265 only.
Is it faster than LAV Video decoder or divx H.265 ? Have you done any tests ?

Please keep discussions of other software to a more appropriate place. I believe it has a thread somewhere on the forum.

Is there any way to make it possible that LAV Video will show the decoded (Input) Bitrate in Kbps ?
If not, please make this an option to view the decoded bitrate. Thanks. Quote:
I don't think UHD needs 30Mbps too eliminate visible artifacts compared to HD, 10-15Mbps will be enough (especially with HEVC). I think the studios can shove 3 Hours, 35Mbps, H.264, in a 50GB disc. Lets wait and see what they can do with UHD, H.265, and 100GB disc. Bitrate/Size Calculator: http://www.dr-lex.be/info-stuff/videocalc.html Last edited by James Freeman; 3rd November 2013 at 19:08. |

LAV Filters 0.59
Code:
LAV Splitter - Support for demuxing H.265/HEVC and VP9 - Improvements for H.264 in AVI or as raw video streams - Improved stream detection in files which start with a few seconds audio before the video - Improved timestamp handling when demuxing seamless branching Blu-rays, fixes a few hicups/freezes mid-stream LAV Video - Support for decoding H.265/HEVC and VP9 - Accept H.264 from the MainConcept demuxer - Added support for DV Video from Canopus cameras LAV Audio - Fixed playback issues on a few DTS and DTS-HD tracks Its been quite a while since the last release, however the changes still look relatively short - and well, yes they are. I was on vacation, on various business trips and generally very busy. However I hope that development will pick up again in the coming month. Anyhow, the big thing in this version is of course support for HEVC. While its certainly not perfect yet, it is relatively fast on 1080p content already. Please do not bother to report HEVC files which do not play, instead report them to FFmpeg directly, since they are still actively working on the HEVC decoder. Many older files from early versions of the encoders may also be invalid, and therefor not play properly. Other then that, a bunch of fixes and improvements, some named in the changelog, some internal or too small to make the log. Another maybe note-worthy change is that i moved to Visual Studio 2012 and GCC 4.8.2 with this build. I have even considered moving to VS 2013 in the near future, LAV already builds just fine with it, and I like the improvements Microsoft made - just for anyone curios what I use to build official versions. Anyway, have fun!

I have a question regarding playing games & video playback using multiple monitors:
I play dota on my laptop at 1080p and also like to watch twitch.tv streams (720p resolution in this case) on my second screen (1280x1024) alongside. my aim is to find a way of playback of the twitch stream which results in least decrease of fps in the game (dota running on the nvidia card, the stream/vlc/mpc atm with the intel hd 4600). when only playing dota, then my fps varies about 35-45. when using VLC to play the twitch stream (using the normal browser via adobe plugin is definately slower) then I get the least decrease of fps do far with usually still being around 33-39 fps when I now try to achieve this or better with mpc & lavfilters for video decoding I dont seem to be able to get better results than VLC does. regarding video decoder settings, selecting no hardware acceleration at all does still offer the best results with fps of ~29-35 ( (also with v0.59). its gets a bit worse with dxva2 copy back and is worst when using quicksync. from what Ive heard, the more load is on the intel HD alongside the nvidia, the more it could slow down the nvidia because of copying stuff to video ram or something like that? as for the renderer, madvr wont work at all as the intelHD gpu is way too slow for that. VMR9 renderless does provide slightly better results than EVR. still as said, I dont know what VLC does, which renderers or decoders it uses to achieve a better result than mpc & LAV. would anyone know what settings I could try with mpc & lav for improvement?

It's nice to see that the x64 version is faster now, I remember it being a bit slower before. Around 5% faster with H.264 and 8,5% faster with that H.265 2160p sample.

you can also try madvr with dxva image scaling, bilinear chroma scaling. Last edited by mindbomb; 3rd November 2013 at 21:07. |

tried it, fps rate is ~26-34 then. so VLC is still faster.

Greets, thanks for new .59 update. After updating, the very first mp4 file (AVC;AAC) I played started in pause mode and had no sound. Sound would try to stutter every 30 seconds as if it was trying to play but failing so mostly the video was just silent with the occasional sound burst. Reverting back to 58.1 the files played with no problems. So am assuming that this new mp4 AVC/AAC problem with version .59 will be reported by other users soon. If not, I will losslessly cut out a sample out post it up. Cheers

do you think it might be an issue with power settings? that is, vlc is using the cpu, thus preventing throttling, leading to increased performance?
cause i dont think anything can impact the system less than evr and dxva native. also, check to make sure dxva native is actually being used in lav video, it may not be compatible with a filter you are using or something. Last edited by mindbomb; 4th November 2013 at 04:57. |

MPC-HC has also been using a version close to 0.59 for a while in nightly builds, and i haven't heard anything from them, either.

LAV Splitter - Support for demuxing H.265/HEVC and VP9 LAV Video - Support for decoding H.265/HEVC and VP9 - Accept H.264 from the MainConcept demuxer What are the new SUBTYPEs associated with H265/VP9 and possibly the update for "MainConcept h.264 demuxer" ? |

HEVC uses the FourCCs 'HEVC' and 'HVC1', VP9 uses 'VP90', the new H.264 type is {D2D71CB-243F-45E3-B2D8-5FD7967EC09B}
