LAV Filters - DirectShow Media Splitter and Decoders

[Incendia]

Not sure if this is the right place to ask, but is there any way to make Sony Vegas and/or Adobe Premiere use these for decoding mp4 files? I'm trying to archive some UTCodec YUV422 (ULY2) files as H264 High 4:2:2 using x264, but Vegas refuses to read the video ( Instead showing a green frame ), while Premiere Pro seems to offset color channels or something ( See : http://imgur.com/a/su1EJ ).
As expect, 10bit support is even worse, so I'm not even considering it.

@nev:
is git.1f0.de git protocol closed?

$ git pull
fatal: unable to connect to git.1f0.de:

$ telnet git.1f0.de 9418

I don’t know if it is a problem specific to LAV or the disc, but the menus for Vanilla Sky are very slow and unresponsive. Most other DVD menus now react immediately when you mouse over them.

I have a few others that have a slightly delayed response, but nothing so bad as this.

How can I extract the menus to send them to you? (I am running AnyDVD if that helps)
I'm currently going through my whole DVD collection to see if there are any other titles like this.

Nev tells you exactly how to extract the menus...

If you still have a problematic menu, you can extract only the menu from a DVD by simply zip'ing up all the IFO/BUP files, the VIDEO_TS.VOB, and all VTS_xx_0.VOBs (VTS files ending with 0 are for menus, 1 and above are content).

Sorry, I do try to stay current on this topic, but must have missed that.

If you're using MPC-HC there is a keyboard shortcuts page.

Works well: DVBViewer + ATi 6450.

Thanks Nev.

It mostly depends on how the menu is setup. This menu for example looks like a static image, but its still encoded as a movie at 25 fps, simply showing the same image over and over.

Because of queueing in the renderer, this can result in higher reaction times, especially if you use madVR - it queues a lot more (also depends on your queue settings in madVR)

A movie with an actual still-frame menu will simply repaint this frame on demand, and because there are no other frames to queue, it shows faster.

Is there no way to tell madVR to flush the queue?

[Superb]

Nev, maybe LAV Video could set madVR to use half (or even less) the buffers when showing the menu? and then revert to the original values when the main title starts...

STDMETHOD_(BOOL, SettingsGetInteger)(LPCWSTR path, int*    value) = 0;
STDMETHOD_(BOOL, SettingsSetInteger)(LPCWSTR path, int     value) = 0;

(set the following to lower numbers)
//     gpuQueueSize,                GPU queue size,                                                  integer, 4..24
//     backbufferCount,             no of backbuffers,                                               integer, 1..8
//     preRenderFrames,             no of pre-presented frames,                                      integer, 1..16
//     backbufferCountExcl,         no of backbuffers,                                               integer, 1..8


STDMETHOD_(BOOL, SettingsGetBoolean)(LPCWSTR path, BOOL*   value) = 0;
STDMETHOD_(BOOL, SettingsSetBoolean)(LPCWSTR path, BOOL    value) = 0;
(set the following to false)
//     delayPlaybackStart2,         delay playback start until render queue is full,                 boolean
//     delaySeek,                   delay playback start after seeking, too,                         boolean

That's a bit "dangerous" because changing settings this way is a global change that is stored to disk, so if playback crashes for some reason, the "half buffers" would stay the new setting forever. That is until the next playback session, when LAV would half the queue size again, which after the next crash would become the new settings.

Right now madVR cannot detect when LAV changes the DVD menu, if the menu is a video file (and not a still frame). This problem would be solved if LAV used the new subtitle interface. Then madVR would know when the menu changed and could internally flush the queue to make the menu react quicker.

[sexus]

you should let nevcairiel know about this new subtitle interface

[madshi]

He knows about it. Actually he already mentioned that he's considering using it for the DVD menus.

How would it actually solve it?
Doesn't the renderer poll for subtitle frames, or did i miss an API to push changes? Doesn't seem like it really allows better low-delay handling then my current way of doing things.

There is also the problem of still-frame redraws, i'm not sure how the interface really solves that.
Your OSD interface on the other hand could manage all that.

Seem to be having a problem with LAV Filter reading subtitle flags inside an MKV file. It seems to load them regardless if I set. No Subtitles, Default or Only Forced.

I am using MPC-BE so that could be to blame?

LAVFilters-0.53.2 & MPC-BE.1.0.3.1.1239.x86

[nevcairiel]

MPC-BE has some "features" that override LAVs stream decision.

[sexus]

interesting perhaps this could be fixed , am a avid mpchc be user myself

[nevcairiel]

Nothing that can be fixed by me. If the player chooses a stream after LAV has already done its choice, its out of my hands.

[Dion]

I can confirm it doesn't affect MPC-HC. So probably not an issue with LAV. Guess I will just keep using HC.
