PotPlayer will pipe to Avisynth automatically under the hood, thus avoiding indexing.

Thanks for the tip. Currently I'm exploring the same kind of thing with MPC-HC using CrendKing's Avisynth filter. As far as I can tell it inserts Avisynth between LAV decoders and the renderer, so no indexing required either, but I'm having a couple of dealbreaking issues with it (see Issues tab in the Git).

What an important changelog!

AviSynth: added support for XYZ12LE format (represented as RGB48).

Thank you so so so so much Asd-g!
I've never felt so welcomed and cared for, honestly!
Every single time I raise an issue with this indexer, it's taken into consideration and addressed.

I love LWLibav



By the way, I tested it and it does indeed work.
While FFVideoSource() converts XYZ to YUV, LWLibavVideoSource() preserves the original XYZ inside the video, thus displaying it correctly and allowing us to work directly with XYZ!

@FranceBB, you can comment about XYZ in FFMpeg, i think author will update for it

Here is a clip which LWlibavVideoSource cannot seem to play properly: https://drive.google.com/file/d/1lHB...usp=share_link

It seems to have something to do with that soft telecine / repeat fields issue causing it to go out of sync with audio because the repeat field flags aren't being obeyed correctly (discussion about that back on page 58).

file = "480i multiple cadences.mkv"

AudioDub(LWlibavVideoSource(file, repeat=false), LWLibavAudioSource(file, stream_index=-1))

ScriptClip(last, """SubTitle(String(propGetAny(last, "_FieldBased")))""")

If I set repeat=true I get:



The _FieldBased frame property might offer a clue: the panning sequence starting at 1:25 is showing a _FieldBased value with pattern: 0-1-2, which means "progressive-bff-tff" which doesn't seem right for a 3:2 sequence, so maybe it has something to do with that?

FFMpegSource2 doesn't populate the _FieldBased prop, but can play it correctly with rffmode=1 which means "Honor all pulldown flags":

FFMpegSource2(file, rffmode=1, atrack=-1)

But, something is still not right: if I do simple bob deinterlacing with:

FFMpegSource2(file, rffmode=1, atrack=-1)
Bob()

The result is that "jumping back and forth" artefact which looks like the field order is wrong. So I try to correct that with:

FFMpegSource2(file, rffmode=1, atrack=-1)
AssumeTFF()
Bob()

^ this is better, but there are still some sequences which appear to have the wrong field order -- look at the "Series Story Editor" at 00:14, it still moves in the wrong direction for one frame before jumping forward 2 frames. I would have thought that was impossible with Bob().


edit: it seems these dynamic changes in field order need to be obeyed, in addition to the repeat field flags, in order to get correct playback. Still, it doesn't make sense to me as I thought analogue CRT would just scan field1 followed by field2 at all times. Seems my understanding is completely wrong: https://www.dvmp.co.uk/digital-video.htm

Thanks, done.

I have a problem with small lagarith clips made from pictures with repeated null frames: https://www.mediafire.com/file/hwdf8...ditos.avi/file
Using it to make a slideshow. DirectShowSource will add an extra frame. And LWLibavVideoSource will only return one frame instead of 150.
This is my test script:

nameS="07 - creditos"
extS=".avi"
# v= DirectShowSource( nameS + extS , ConvertFPS=true)
# v= trim(v, 1, length= framecount(v)-1 )
v= LWLibavVideoSource(nameS+extS)
v= ScriptClip(v, """
Subtitle(String( int(current_frame/30))+" seconds",
\ align=5, size=height(v)/16 )
""")
# v= info(v, size= height(v)*.05)
return v

My guess would be that the endianness of the PCM audio was not correctly respected.

Hi, all my Videos containing pcm_s16be or pcm_s16le audio are fully distorted when read with LSmashAudioSource, while LSmashVideoSource is just fine. I've got the latest build from 20221109. It is a pity to wait for indexing of workaround solutions just to get audio right.

Any news about this ?

[kedautinh12]

Are you try LWLibavAudioSource??

[Hotte]

I did and it works. But it needs indexing, which I'd like to avoid and should not be necessary due to the fact that LSmashVideoSource works perfectly on my files for the video-stream without any indexing.

And: I do not understand why these files play instantly without issues and without any indexing if you open them directly with VDub2.

Something seems wrong with LSmashAudioSource and PCM-Audio from everyday-movs from everyday-cams like Nikon D5300 or Panasonic G9.

[kedautinh12]

You can create issue to fix faster or developer will explain about it

Thanks. I opened issue #26

[StainlessS]

I do not understand why these files play instantly without issues and without any indexing if you open them directly with VDub2.

I think that is because the ISO container files [mp4 etc] that LSmashVideoSource() opens, already have some sort of index, as do AVI files.

EDIT: As posted in #1422,

    Function IsISOFileName(String s)        {s=RT_GetFileExtension(s) Return(s==".mov"||s==".mp4"||s==".m4v"||s==".3gp"||s==".3gpp2"||s==".3g2"||s==".mj2"||s==".dvb"||
                                            \ s==".dcf"||s==".m21"||s==".m4a"||s==".m4b"||s==".m4p"||s==".k3g"||s==".jpm"||s==".jpx"||s==".mqv"||s==".ismv"||s==".isma"||s==".f4v")}

At least one of above is an audio-only ISO file. [".m4a"]

Only use LWLibavVideoSource() for non ISO video files. [attempt to open non ISO with LSmashVideoSource() will fail].

EDIT:
Here is a reasonably simple function to open files based on extension, works pretty well and could be used as an example to create your own,
https://forum.doom9.org/showthread.p...68#post1874068
Is implemented as an Avisynthesizer_Mod template.

See also the following posts where may have been improved.

And here:- https://forum.doom9.org/showthread.p...11#post1880511
Hello_Hello did his own version of a similar script.

Edit: Also, here description of my function (presumably the last mod of mine in that thread), where can change preferred order of source filters tried [EDIT: via Pref arg].

I think for the older L-Smash it should be msvcr100.dll.
There's a copy in the "lsmash-r784-150316-XP.7z" file but not in the "MeGUI\tools\lsmash" folder. I assume there should be?

I'm not having problems as I have the appropriate runtime installed, but I thought I'd mention it.
