LAV Filters - DirectShow Media Splitter and Decoders

when you add stream switching to the tray icons, will you finally add ts program switching? or is that far off still?

Tray icons will expose existing features, i have no immediate plans to prioritize any other features just because there are tray icons now.

When using LAV splitter, mkv containers support MPC-HC's keybinding for Jump Forward (keyframe) and Jump Backward (keyframe), which let you move through a video very cleanly (because by nature keyframes are often at scene/shot changes). But for AVI and MP4 containers it doesn't seem that LAV Splitter responds to the keyframe keybindings. Should they be behaving similarly to mkv containers and moving to the Prev/Next keyframe and I'm just having difficulty or is this not an (as yet?) implemented function?

It may be that this is related to this Issue but it hasn't had progress in a year after mentioning mkv seeking development.

This only really works if the file exposes a list of keyframes to use for this, which is only really reliable for Matroska so far. It may be possible to get this to work with MP4 as well, but unlikely to ever work properly with AVI.

As a fallback, I've been using the AVI and MP4 splitter included in MPC-HC's internal filters which go forward and backward along keyframes successfully for those containers. I can't say what their mechanism is to find keyframes or if they're approximating keyframes but it seems to be generally accurate.

Windows version, make and model of your HW, players you tried, etc.

Thanks!

Will do!

Today I downloaded a mkv file which has 2 editions, this is my first time to play such files.

Well, like the Open Linked Files feature, haali is needed for the file.

nev, is there a possibility that LAV supports muti-editions files one day? Haali is really out of date.

[nevcairiel]

Its really the same feature.

I plan to get to this "soon", meaning sometime in the next few month or so.
If anyone has simple samples that demonstrate either external linked segments or editions within one file, please do share.

Thanks, that should help. Always easier to have files to work with than having to go hunt them down first.

This file I have does not seem to be compatible with CUVID in LAV. Any idea why?

Thanks for the quick answer. Do you know if this is a hardware limitation or software limitation?

[wanezhiling]

The former, at least the driver doesn't support and never.

Here's some samples I created that demonstrate 3 types:
http://www.mediafire.com/?26p251ej90bn9k7

If you play "File Linking1.mkv", it will append "Segment2.mkv" by way of the segment uid in the Matroska header.

If you play "Segment Linking1.mkv", it will also append "Segment2.mkv", but this time via the segment uid in the ordered chapters.

"Ordered Chapters.mkv" is one file that contains the same parts as the first 2 examples, but with a 3rd segment in the middle. The ordered chapters will skip the 3rd segment and play as it should. It also contains a second edition, which will play only the 3rd segment.

Hope it will be helpful for you.

“Default”

The “Default” mode will select subtitles in accordance with the typical interpretation of the Matroska spec. That means that subtitles matching your language preference will be loaded, as well as subtitles marked “default” or “forced”. If none of these factors apply, no subtitles will be loaded.

Since “Default” mode is used by most people(at least 95%+), I think showing a subtitle is always much kinder in case some people complain.

I suggest:

A file with only one subtitle, whether its marked “default”“forced” or not, just load it.

A file with several subtitles, neither “default” or “forced” flag exists, load the first subtitle.

What do you think nev?

[nevcairiel]

The current mode works just fine. I don't like showing subtitles by default.

I'm sorry, what? Most files (especially from "official" sources) have subtitles but most people don't want/need them.

Forced subtitles should obviously be shown by default though.
