Alternatively, you can try these (for 32-bit players): https://files.1f0.de/lavf/plugins/libmfxsw32-v1.7z https://files.1f0.de/lavf/plugins/libmfxsw32-v2.7z https://files.1f0.de/lavf/plugins/libmfxsw32-v3.7z (This is 8.18.6.8, the one the latest LAV nightly comes with)

What are the "old" LAV versions you tested with?

Mevunky says it works when using older versions of LAV though, which is strange and wouldn't point to a filter chain problem.

Oddly in properties the audio stream is displayed incorrectly: Audio: DD+ 48000Hz 6ch 9216kbps (incidently this is the video bitrate not the audio bitrate) Old LAV shows this correctly: Connection media type: Audio: DD+ 48000Hz 6ch 640kbps Old LAV being 0.70.2.1-git.

Hi, nevcariel, could you have a look at this https://superuser.com/questions/8422...e-aggressively and explain how to properly implement that "hack" in recent versions of LAV?
It mentions MPC-HC in the title but it's all about LAV Splitter in reality. |

Did you look at the LAV settings? You can configure that since forever.

So to increase the amount of "read ahead" caching what is the correct way of setting LAV Splitter? Sorry if it's been asked before or it's by now "old knowledge". Thank you. |

Change the value "Maximum Queue Packets". It's the now-configurable setting that is referenced as a #DEFINE in the discussion from your link

I'm experimenting with it but it seems that, no matter what I set there, MPC-HC x64 doesn't use more than about 450MB of RAM (I have 32GB). Last attempt had me setting Maximum Queue Memory at 8192 and Maximum Queue Packets at 100,000. And still MPC-HC is using 450MB of RAM.

The buffer size reported by MPC on my install does indeed grow when I change that setting in LAV Splitter.
This is with the default 350 packets: https://drive.google.com/open?id=1jQ...1oGqPW-kOyZzq- And this is with it set to 3500, and the buffer is indeed ~10x bigger: https://drive.google.com/open?id=1F9...oTLVZaTzIuf3ao Does that value change on your install when you change settings in LAV Splitter? (Edit: when I set the values to 1024 MB/700000 packets, the private working set size of MPC grows to 1,3 GB of RAM, so it is working as intended)

It isn't a file buffer. It is a decoding buffer. So if decoding is relatively slow, then it will take longer to fill the buffer. Try pausing and it should keep growing. It works correctly here. You may need to use larger packet value.
@Mevunky If older version fall back to using MS decoder it means bitstreaming failed then as well. If you are using S/PDIF then you should only enable AC3 and DTS. Other formats require HDMI. If even plain AC3 and DTS are not working then you need to select correct audio device in output settings of MPC-HC. |

From what I understand, Mevunsky is saying that when it falls back to MS Decoder it does bitstream successfully?
Is it possible that the MS Decoder decodes the EAC3 and re-encodes it to basic DD640 to bitstream it? I seem to have read somewhere in a Dolby document that licensed EAC3 decoders can do that.

Its actually a demuxing buffer, which is pretty close to a file buffer, since demuxing is generally pretty cheap.

The note about google was for the only preview video by google which is de-interlaced and re-encoded. So no deinterlacing by the browser comes into play. |
