Should be resolved for the next nightly.

I have a question about the Advanced Track Selection, i set to:
Audio: eng,ger Subtitle: eng:eng|f;ger:ger|f;*:off After using a Header Editor to fix the incorrect und marked audio track to eng and making sure the forced sub track is correctly set, the subtitle was not selected. After some time i discovered that the file ad Tags in them and this is probably the reason didn't work since the tag says also und as audio language. Code:
<Targets> <TrackUID>1</TrackUID> <TargetTypeValue>50</TargetTypeValue> <TargetType>MOVIE</TargetType> </Targets> <Simple> <Name>CREATION_TIME</Name> <String>2018-09-05 17:15:26</String> <TagLanguage>und</TagLanguage> <DefaultLanguage>1</DefaultLanguage> </Simple> <Simple> <Name>LANGUAGE</Name> <String>und</String> <TagLanguage>und</TagLanguage> <DefaultLanguage>1</DefaultLanguage> </Simple> |

I think I found a bug in FFmpeg.
In libavformat/mov.c function mov_seek_stream Code:
timestamp -= (sc->min_corrected_pts + sc->dts_shift); I have a MP4 where seeking to keyframe was slow because of wrong timestamp value. Removing the above line fixes that. |

mov_fix_index is not used by LAV, and that line isn't new in the latest build. So that doesn't seem right to me. Please provide a file that seeks slower then it used to.

Anyone ever run into an issue in which a bitstreamed track turned into a high-frequency, garbled mess of noise? I am getting that in my rip of "Den of Thieves," in exactly the same position, every time. I'm going to assume it's an issue with the DTS-HD MA track, as none of my other movies have the same problem, but it does play back fine if I have LAV decode it to PCM, and no error messages popped up during muxing...

Does that also happen when you play the original M2TS directly ?
If yes then it may be a compatibility issue of your AVR's decoder with that particular track.

Incomplete build instructions
I tried to build LAVfilter on Windows with Visual Studio 2015, using the instructions provided. Unfortunately this was not possible as they are incomplete.
In your script you are using Vswhere. Any documentation or reference about that is missing. Vswhere can be downloaded from https://github.com/Microsoft/vswhere and need to be placed in a specific folder "C:\Program Files (x86)\Microsoft Visual Studio\Installer" as the script uses an absolute path. |

But using that script is not needed anyway, its just convenience. You can just run the shell scripts and then compile the solution yourself.

Anyone have trouble with both LAV 0.72 and LAV 0.72-15 Nightly and 4K content? it detects my my GTX 960 in D3D11 drop down menu but CPU does all the decoding (HW decoding for 4K is checked). It goes for both D3D11 and DXVA2 Native, but 1080 content does activate hw decoding. MPC-HC's internal LAV decoder 0.70-2.1-git does hw accelerate 4K.
P.S. the problem seems to be limited to 4K HFR (60 fps) content. I am using MadVR but even EVR doesn't run it at 60 fps and it's choppy Last edited by mytbyte; 2nd October 2018 at 13:37. |

no issues here on AMD RX 580 on either version. Driver 18.9.3.
Do you have it set to NATIVE or have you chosen your card from the drop down with D3D11, it should be set to NATIVE as far as i'm aware.
