L-SMASH Source

[bruno321]

Thanks for the explanation. For the moment, for uninteresting reasons, I can't update the XP installation. What I've been doing is either mux into an mkv and use ffvideosource, or use the very old DGAVCDec, which doesn't always work. I was wondering if there was a better alternative in the XP scenario, but perhaps there isn't...?

Here's a link to qyot27's last XP-compatible FFMS2 C-plugin.

Edit - The best alternative for XP would be an older version (2052?) of DG's source filter for Nvidia cards but I don't know if he would be willing to make it available. Also, it's not free but the few bucks he charges are well worth it.

[bruno321]

Thanks. I already use ffvideosource succesfully, but then I feed it a demuxed mkv. In the avisynth.nl page I see that ffvideosource also accepts m2ts files, but I read that

"M2TS, TS: Seeking seems to be off a few frames here and there"

which makes me a bit anxious.

I agree. In that case there's just DGDecNV as far as I can see.

Thanks for the mention, Groucho! I thought DGDecNV 2053 should work on XP. Does it not? Also, 2052 has always been available in the binaries area.

Shouldn't matter if you are just transcoding with linear access.

[StainlessS]

You could just do away with ffms and LSmash altogether, this does a faily good job, never (well rarely) problems,
just convert to AVI and have pretty much 100% frame accuracy and zero problems.

AFAIK the last XP compatible version of LSMASH is the 2015-03-16 build you can find here: https://www.mediafire.com/folder/17q...t/LSMASH-Works

It works fine, however there's a catch: it only supports 8bit planar, so if you index an high bit depth file (10bit or higher), it's gonna index it and output 16bit interleaved instead, which ain't a big deal, since you can convert it back to 16bit planar anyway, but still...
Besides, since it's quite old, it might not be able to index new files like AV1 and other things. Your best shot for pretty much everything other than some particular cases is ffms2 C plugin which has been updated by qyot27 for quite some time before he/she dropped support: http://www.mediafire.com/file/oi31n1...lastxp.7z/file

(I'm like 99% sure he's a dude, but he has a girl as an avatar so I'll leave the 1% margin open for doubt/discussion)

ffms2 will be able to decode more things and it also supports planar high bit depth, which means that if you index a 10bit planar source, you'll get a 10bit planar output and so on.

Bonus bit: CoRoNe is still compiling ffmpeg for Windows XP x86, so whenever you can't index something, there's always ffmpeg lossless (huffyuv or lagarith or utvideo or ffv1 or whatever). I also asked him to compile ffms2 c plugin with his very own changes to ffmpeg so that we can keep it XP-compatible; he didn't reply yet but I hope he will do it.

Jokes aside, I'm pretty sure everybody has a Win10 copy for productivity stuff just like I do for Visual Studio, AVID Media Composer, Protools, Davinci Resolve and also Avisynth, but I'm still attached to my beloved XP for leisure (and AVS is also leisure xD)...


@StainlessS... good bat, it might come in handy. Out of curiosity, do you still have your copy of XP or did you ditch it when you moved to Windows 7?

I used to like you.

[StainlessS]

Still have on several machines, two never on-line (well one is a laptop which I only use for playing movie whilst at my Win7 m/c),
and another one which rarely goes on-line (except in guise of Cinnamon Mint EDIT: Usually just to update it), EDIT: that one is my regular encode machine.
Also got two or three more Laptops with XP on them, I always forget bout them, never turned them on for a couple of years.
EDIT: Probably dumped about 6 to 8 XP m/c's in last 4 or 5 years, P4 or less.

I really see win10 better than win7

but still, nothing better than winxp even if I don't use it now

FWIW I don't have a problem using LWLibavVideoSource, which I hadn't read about until today.

[leon]

Using LSMASH 20200322 in VapourSynth, HW decoding doesn't seem to work. I'm trying to decode H.264 8bit in a simple script like this:

clip = core.lsmas.LWLibavSource(source=r"D:\video.mkv", prefer_hw=1)

I don't see any GPU usage. Am I doing something wrong?

And apparently "prefer_hw" can take just about any value, could you please make it fail in the case of invalid values and also if the selected decoder is not available?

[stax76]

@leon

Please provide avsmeter benchmark results like so:

[real.finder]

maybe make an optional cmd tools to do index for LSMASH will be a good idea, so user can now when the indexing finish, like ffindex

My script:

LoadPlugin("C:\Program Files\MeGUI\tools\lsmash\LSMASHSource.dll")

LSMASHVideoSource("D:\video.mp4", prefer_hw=1)

@leon

Please also post the avsmeter benchmark result for software decoding:

LSMASHVideoSource("D:\video.mp4")

I suggest to use avisynth 3.6.

[Groucho2004]

I have a hunch that gpu decoding with lsmash needs at least OpenCL 1.2.

Edit: What I meant to say is that the cuvid support for your card is probably insufficient gpu decoding.

[stax76]

Sure it does.

1. It's exactly what staxrip does.

2. I verified it in the console.

Try a large enough file and delete an existing index file before.
