As mentioned in my response to the original request, its still on the list, but undetermined when I'll get to it.

Hi Nev,
Would it be possible to stream and render two external srt subtitle files at the same time (madVR )? I mean reading 2+ lines of text in different lanugages at the same time.
Thanks

nevcairiel · 23rd March 2014, 23:44

You'll need a subtitle renderer that can render multiple subtitle streams, LAV alone does not and will not do such hacks.

With LAV Source is not possible - it handle single pin out, and no way to request data from different subtitle's track at one time

He wants external SRT files. Can just open two of them.

tobindac · 24th March 2014, 15:46

splitter appears to be preferred internal version. How to fix? The video and audio decoders work fine.

All are set as external filters on 'Prefer'.

If you have problems with a player, you should ask in the appropriate place, ie. the support thread for that player.

Just had a very weird issue with LAVFilters 0.61.1 together with the AVStoDVD preview option. It only happens when using the LAVFilters installer, when using the ZIP file everything works perfectly.

My system is WinXP (32bit of course). The AVStoDVD preview uses the infamous quartz.dll (DirectShow ActiveMovie). DirectShowSource is its default source filter, the author recommends ffdshow which works nicely.

For several reasons I wanted to replace ffdshow with LAVFilters, and with earlier versions (0.59.1) there also were no problems. But after using the 0.61.1 installer the AVStoDVD preview just hangs and crashes the main program.

This issue only affects the preview, the actual encoding works fine.

The funny thing is that when I use the ZIP file instead of the installer, the preview works perfectly. I can live with this now since I figured out the command line for setting up the filters, but I still do not understand what the installer does what crashes the AVStoDVD preview.

I did some more tests, and I found that after using the installer once there is no way back. Uninstalling and then use the ZIP file does not help, there is something the installer does to my system which is not reverted by uninstalling. The only cure at this point is restoring a current backup. Since the installer for earlier versions did not cause problems, I suppose that there were some recent changes to the installer which are responsible for this issue.

Any ideas?

Cheers

I think I may have found a bug. I was playing a 24 bit stereo flac. My mixer setting was for 5.1, but with mixing disabled for stereo sources. The output from lav audio was then 32 bit integer.

@manolito
Current LAV Filters is not fully compatible with AviSynth 2.5.

You can restore the standard splitter for AviSynth with this:

Code:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Wow6432Node\Media Type\Extensions\.avs]
@=""
"Source Filter"="{D3588AB0-0781-11CE-B03A-0020AF0BA770}"

You don't lose any precision, so what's the problem?
Maybe your output device or drivers don't support 24bit format?
If you go to LAV Audio decoder properties during playback you can see currently used and all suppoerted formats in the Status tab. It works for me (LAVFilters 0.61.1), see below.

EDIT: I can reproduce it with mixing settings listed by mindbomb.

Thanks a million, clsid...

In the meantime I had followed many different leads to track down the problem (like filter merits, VB runtime files), but it all ended at a dead end.

BTW for WinXP the "Wow6432Node" entry does not exist, the reg file must look like this:

Code:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Media Type\Extensions\.avs]
@=""
"Source Filter"="{D3588AB0-0781-11CE-B03A-0020AF0BA770}"

So it's time for LAVFilters 0.61.2 I guess. Or are filter developers considering AviSynth 2.5x obsolete already? And in any case the installer should have reverted my registry to the pre-install settings upon uninstall.

Cheers

yea, you have to specifically set enable the mixer, set it to 5.1, and enable don't mix stereo sources to reproduce this issue.

Sorry. You're right, I can reproduce it with your mixing settings, but I still don't see how it would be a problem - you don't lose precision, your soundcard (supposedly) supports 32bit and by mixing you're already "modifying" the audio stream, so having it "untouched" is out of question.
BTW, I get 32bit float with mixing to 5.1 and 32bit integer with mixing to 5.1 and "don't mix stereo sources".

LigH · 27th March 2014, 10:07

Stuffing 24 bit samples to 32 bit is probably just avoiding the processing of interleaved values in DWORD registers for a better performance, similar to graphic modes using 32 bit RGB(0) pixels.

The MPC-HC window allocates 500px * 500px for the artwork, but the screen stays black.
The "Play" button is pushed, but nothing is played (stays at 00:00).

If I switch the splitter to Haali, I can read this file (see more infos here).

Sorry if this problem is not only LAV Splitter related, I'm no expert.

AVSplitter plays the file fine too.

Seeing an odd behavior when using a SampleGrabber filter after the video decoder and was wondering if there were known issues.

It's an H264 stream (YV12) and the graph is

elecard net source -> elecard push demux -> lav video decoder -> sample grabber -> EVR

It looks like the chroma's are getting shifted around a bit (red and blue seems to be above where they should in the image). I can get it to display properly by stopping the graph and starting again, almost as if the pin types aren't being updated correctly with a grabber between the decoder and the renderer?
