Very well, it was worth asking about.
It's honestly not a feature I see myself using very often, since generally subtitles are done at more readable sizes to start with, but changing a setting it is a lot easier than demuxing a file, editing the script to change text sizes, and saving a new external subtitle script for use or remuxing a whole new file with the changes. What about ordered chapters support? Is that in the future plans?

Sure, some day. Its not high priority (for me), as i don't even have a single file that would need it.
Its also alot of work...

Actually, you can have it in one file as well. Ordered chapters is not only about external segments, but also about different editions of one movie in the same file (theatrical + extended cut, or something like that). But its really not used much, which is kinda sad.

Now that the subtitle discussion is out of the way (for me anyway), I have an odd issue I wanted to bring up. I'm seeing a system performance issue when using a specific playback setup, and I don't know where the issue lies.
If I use Haali's Splitter, LAV video decoder, and madVR for picture rendering, in that combination, playback still seems to work, but I see very high disk activity being attributed to the system (not the playback app itself) according to Windows. If I change to ffdshow for decoding. Or change to Haali's Renderer and leave LAV for decoder the problem goes away. I can't tell if this is a LAV decoder issue or a madVR issue or Haali's splitter has something to do with it.

At least for me using Haali splitter uses way more CPU, e.g. 5-10% more over LAV Splitter - also haali uses the disc for some kind of system cache (or similar) if I remember correctly so that may be it - there's an option to choose how much space it uses in the haali splitter options I think. |

Hmmm. That's a thought. Except I'm using Haali's splitter in all three of the mentioned configurations in my post. It's only when it's LAV decoder + madVR I have this happen.

Some versions of Haali had bug with seeking in paused graph that can result in excessive disk and decoding activity. On the other side, splitter itself using 5-10% of CPU looks unrealistic: there is nothing complex to compute there to eat that amount of modern CPU.

Well he said 5-10% more than LAV, not of all CPU resources. I honestly don't know how you would measure a difference like that unless you were using unbearable old hardware to start with.

nev, would you consider implementing an option to output 7.1 and 6.1 channels as 5.1 in LAV Audio without dropping the information of those 1 / 2 channels?

Hey guys,
I would like to ask what LAV Filters does? I read on the first page but didnt quite understand. For example: does using LAV Filters improve Video or Audio quality in anyway? Would be nice if someone could explain bit more. |

Anyway you got your answer from Nev. Quote:
LAV is a set of splitters and decoders. just like any other ones but somewhat different, somewhat faster, with active developer, compared to others, with P010 colorspace support. Last edited by Keiyakusha; 5th November 2011 at 14:48. |

lets hope it doesnt degrade the quality compared to how stuff is supposed to be viewed in terms of standard specifications

@StrifeLeonhart, Keiyakusha Using LAV filers does improve video quality... if we compare it to CoreAVC for example (on 10bit video). Or at least so I have heard. |

this is mainly a problem of not dropping the additional 1 / 2 channel information I guess. dunno if ffdshow does that when setting the mixer to 3/0/2 + LFE. thats why it would be nice to have at least one solution which keeps all the audio information.
