I hope I understand you right this time

@steakhutzeee: Please don't miss the difference between container and content formats.

Matroska/WebM, MP4/MOV, MPEG PS/TS/PVA ... are containers. They may contain a variety of content formats (like AVC/H.264, HEVC/H.265, WMV/VC-1, VP8/VP9, AV1 ... video, and several audio formats).

Splitters separate the content from the container. Decoders decode the content. You can disable player internal filters for each of them separately. Know what you may have, then you will know what you may want to control.

Thank you very much for the clarification

Automatic nightly builds are broken?

Looks like that.

Latest September commits haven't compiled yet to nightly builds which are still on August.

Strange thing I noticed: since the new dav1d version in 74.1-20, AV1 decoding is actually slower (about 6-7%), both on my Core 2 and my Haswell. (8-bit clip)

nevcairiel · 16th September 2019, 18:56

The Virtual Machine that does my nightly builds is currently down, I'll bring it back up soon.

Regarding dav1d performance, sometimes security fixes can cause that, but there is more speedup coming soon as well.
Sometimes multi-threading is also weirdly affected, resulting in overall lower CPU usage, but no gain in speed directly.

ryrynz · 1st October 2019, 00:45

Any chance of a Dav1d update in next nightly?

nevcairiel · 1st October 2019, 11:26

There will be a new dav1d release soon (once some more improvements are done), not before then.

This file doesn't play smoothly with DXVA2 Native. No problem with Copy-back.

Indeed, what a sample!
I tried it using iGPU HD 4400 and Turing 1660 and DXVA2 native doesn't play smoothly.

On the other hand, all copy-back modes QuickSync, NVCUVID, D3D11 etc work fine.

Interesting sample - bug only on LAV Video + LAV Source + EVR/EVR-CP.
If use MPC VR or madVR - perfect playback

el Filou · 4th October 2019, 19:36

Remuxing it to MKV plays smoothly too even with DXVA2 native + EVR.
When looking at EVR stats when playing the FLV, jitter reaches 40+ ms. Timing issue in the container? (Edit: the remuxed MKV is 7/6 seconds shorter video/audio runtime than the FLV)

thrawnrulz68 · 5th October 2019, 06:15

Does anyone know if the MSA1 (Microsoft Screen Application Decoder) still works in the latest version of LAV? For some reason, mine no longer does. I have not had any other problems and even MSS1 and MSS2 (the other Microsoft screen codecs) seem to work. Was MSA1 removed?

There is a sample a little before halfway down this page: http://samples.ffmpeg.org/V-codecs/

thrawnrulz68 · 5th October 2019, 06:28

I was actually messing around with some other samples from the ffmpeg site and the following do not seem to work with MPC-HC 1.8.7 and the latest LAV on my system either (even with all formats checked in LAV Splitter and LAV Video Decoder):

CDXL (http://samples.ffmpeg.org/cdxl/)
Newtek SpeedHQ (http://samples.ffmpeg.org/V-codecs/ - near the bottom)
VP4 (http://samples.ffmpeg.org/V-codecs/VP4/)
VP5 (http://samples.ffmpeg.org/V-codecs/VP5/)

Any ideas?

You may read nice blog of unreleased? NihAV library here Just search for old entries or keywords. I am sure he works at least on VPX codec family.

LAVFilters-0.74.1-21...24.
Players (MPC-BE, MPC-HC) freeze after pressing the stop button when playing YouTube videos.

huhn · 5th October 2019, 14:03

is there a way to get reason/information out of lavfilter when software fallback is used?

nautilus7 · 5th October 2019, 14:37

Hi, I captured a FTA satellite feed the other day, which I have trouble decoding properly (both in my satellite receiver and in MPC-HC with DXVA2). The weird thing is that with no video acceleration in LAV filters, it plays back fine. Can anyone explain me what's wrong/different with this video that creates problems to the hardware decoders? Or is there a bug somewhere? Thanks.
