That, however, was an interesting idea. I'm not getting drops with this. Definitely seems to be pointing to something with LAV.
EDIT: Spoke too soon. Nope, drops with this, as well, just in different spots. EDIT 2: On a hunch I tried going back to the driver version Manni uses and it did not change anything. Thought it could be an nVidia issue. I'm on 416.94 (I won't touch the 417.xx drivers yet until they fix the HDR issues.....AGAIN). Just trying to give as much info as I can to help figure out what's going on. But drops in MPC-xx with and without internal LAV filters are still happening.

Well when I used Premiere Pro awhile back with ffdshow at default settings, I can see it was active and doing the decoding of my MPEG-2 sources, which was unfortunately causing some glitches cause of the two programs conflicting, thus how I discovered it was doing the decoding (when I disabled it). Also it was further evident when I saw the taskbar icon appearing at the bottom corner So I can assure you that ffdshow was definitely doing some work, you can actually force it to in the setting of the program: Is there no way you can implement the same thing for LAV filters??? It would help sooo much! Last edited by Undead Sega; 29th December 2018 at 02:05. |

ffdshow only has a blacklist/whitelist option, which defines which applications are allowed to use it.
Which decoder is used is not controlled by the filters themselves. The application decides what to use. When using the standard graph builder it uses whatever decoder is set as preferred in Windows for a specific mediatype, or whichever filter has the highest merit. You can use Codec Tweak Tool to change preferred decoder settings. |

If Premiere Pro uses the default graph builder, it asks the DirectShow system: "Which filter can help me decoding this source?" - and ffdshow yells the loudest: "Here, I can best, use me!" ... so if you want to give LAV Filters a chance, you first need to tell ffdshow: "Shup up, this kind of source is not your task." by either deactivating this format in its DirectShow filter configuration, or even by uninstalling it ... or by making LAV Filters yell even louder than ffdshow (which is not easy, because ffdshow is already quite loud).
But if Premiere Pro uses a different algorithm to build its filter graphs, how shall we know what to do? |

Which ffmpeg Version to use with LAVFilters 0.73.1
To anyone that has compiled LAVFilters 0.73.1.
Which version of ffmpeg are you using? 1)Tried cloning the master here (v3.4): https://github.com/Nevcairiel/FFmpeg First error is "missing avpriv_mpegts_add_stream" 2) Tried fork V3.3 from MPC-HC https://github.com/mpc-hc/FFmpeg/releases First error is "missing av_demuxer_iterate" 3) Official ffmpeg site https://www.ffmpeg.org/download.html Missing lots of things as expected. Please let me know if I am posting to the wrong area. Any help greatly appreciated! |

The version of FFmpeg LAV uses is referenced both in the readme as well as the first post in this thread, as well as directly linked to the sources through a Git submodule. It should really not be that hard to find it.

Why does LAV Audio output in 32-bit float for 24-bit TrueHD and DTS-HD MA tracks? Doesn't that mean the track is no longer bit-perfect?
EDIT: Okay, apparently it does on a technical level, but some DACs seem to sound different when the bit-depth is upconverted... Last edited by Megalith; 4th January 2019 at 04:37. |

integar -> float conversation are "lossy".
are you using the mixer or something? this will turn the audio into float point because that's more "accurate" lossy processing is usually better done in float with audio in mind. and you wouldn't even believe what a DAC has to do to lossless audio before it is doing the conversation... |

https://en.wikipedia.org/wiki/Single...g-point_format There's no "upconverting" unless you think that 24 and 24.0 are different numbers. |
