one little question (and maybe stupid) about vapoursynth plugin (in linux)

the library vslsmashsource.so call boxdumper/muxer/remuxer/timelineeditor for indexing/open videos? or can self handle without these executables

i want build this plugin with lsmash and ffmpeg form git into library (static linked)

boxdumper, muxer, remuxer and timelineeditor are L-SMASH App.
They have nothing to do with L-SMASH Works.
L-SMASH Works depends on liblsmash, libavutil, libavcodec, libavformat, libswscale and libavresample.

I thought the vapourshynt pluging (and l-smash lib) working like:

vapoursynth call vslsmashsource -> vslsmashsource call liblsmash -> liblsmash call l-smash aplications to handle videos -> liblsmash collect the info and send to vapoursynth through vslsmashsource

oks, tanks fot the aclaration.

I added supporting of a hack of high bit-depth input between rev594 and rev603.
For interleaved format (at default), only little endianness output is supported currently i.e. LSB comes at the first byte and MSB comes at the second.
Stacked format is also available but direct rendering is always not available if used.


By the way, does anyone have a PAFF H.264 sample?
I added supporting of H.264 field coded picture handling for LW-Libav part but I haven't tested on any sample containing both frame coded and field coded yet.
I only tested on samples containing field coded only.

using: L-SMASH-Works_r608 (extracted the LSMASHSource.dll and the msvcr100.dll into my test folder)
I called:
Code:
LoadPlugin("G:\Test\LSMASHSource.dll")
LSMASHVideoSource("F:\Testfiles\test2.mkv"))
when trying to open the script with Virtual Dub I get:
Quote:
Avisynth open failure:
LSMASHVideoSource: failed to lsmash_open_movie.
(F:\Testfiles\test2.avs, line 2)
am I missing something? (uploaded the test2.mkv to http://www.embedupload.com/?d=1JUTIYWYCU)

Why do you use LSMASHVideoSource() for mkv?
LSMASH*Source() is for MOV, ISO Base Media and its derived file formats.
LSMASH*Source() uses libavformat only for the first decoder initialization, and demuxes streams by using L-SMASH demuxer API.
Use LWLibavVideoSource() instead.

Are there any plans to include .mpls (Blu-ray playlist) support as input in LWLibavVideoSource? (would be a 'nice to have' feature)

LSS has an impressive speed advantage in relation to FFMS2 (almost *150% in a quick test decoding AVC 1080p CRF6); it appears to use one more thread than FFMS2, but this won't be the only reason?

That additional thread could simply be an OS module that is being used by the decoder. Process Explorer would show details about the threads.

Edit:
Just checked - LSS invokes 5 decoding threads on my (quad) i5 2500K without specifying "threads=x". It's marginally faster than specifying 4 threads.

A few patches that might be useful:

AvxSynth support
https://gist.github.com/qyot27/5794294
(this one is currently broken because it's not creating the function exports correctly under g++ or AvxSynth, or both; it compiles, but that's about it)

Installation rules for the VapourSynth plugin
https://gist.github.com/qyot27/5794299


The third patch is for the case where L-SMASH itself has been patched to install its headers in $(includedir)/lsmash rather than just $(includedir)
https://gist.github.com/qyot27/5794312

Adjusted header search paths
https://gist.github.com/qyot27/5794300
(it does assume that the AvxSynth patch has been applied already)

I've updated the AvxSynth and VapourSynth install patches slightly (AvxSynth plugin is still broken); the URLs are still the same.

'small' feature request: would be nice if could call LWLibavVideoSource with a list of sources and not just with a single source, since one it a bit of a pain when trying to open a blu-ray that uses a mpls file which links to multiple m2ts files.
Code:
LoadPlugin("G:\Hybrid\avisynthPlugins\LSMASHSource.dll")
LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00004.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00109.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00111.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00113.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00115.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00117.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00119.m2ts",repeat=true)\

+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00125.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00127.m2ts",repeat=true)\

+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00133.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00137.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00139.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00141.m2ts",repeat=true)\

+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00149.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00151.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00153.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00155.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00157.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00159.m2ts",repeat=true)\ 
+LWLibavVideoSource("H:\TestClips&Co\BluRay\BDMV\STREAM\00161.m2ts",repeat=true)
return last
(using cache=false on this one will crash Avisynth since more than 3.5GB RAM get consumed)

I have a strange problem with LWLibavVideoSource (L-SMASH-Works_r629) : when I open a ts file including interlaced h264 (recorded on tv) in 1920.1080 25i, the fields are blended (until there that's normal because I didn't de-interlace video) and the resulting frames are doubled, so the video is seen as 50 fps instead of 25 in Virtual Dub and there is movement only all 2 images.
The video is considered as interlaced TFF by MediaInfo.
There is only one line in my script ;
LWLibavVideoSource("F:\myvideo.ts")
Sorry if it has been explained earlier, I didn't read all pages.

@Music Fan

For an explanation read VFR maniac's post in this thread.

For a solution try remuxing to MKV and set repeat=true.
Like so:
Code:
LWLibavVideoSource("Video.mkv", repeat=true)

Thanks a lot, repeat=true works with my ts
But I'm astonished to note that my ts files are in bff and not tff (I see it clearly by adding separatefields in my script), while I believed tv streams were always in tff.
Is it possible that LWLibavVideoSource does a field inversion ?
Or could it be a difficulty to handle TS container ?
I still had to put these files in MKV container to see if the result is the same.

The field dominance is an attribute of the video stream, not of the container.

If AssumeBFF().Bob() doubtlessly returns smooth motion, whereas AssumeTFF().Bob() returns a forth-and-back jitter, then it is correct, and the material was recorded using a camera with a dominant bottom field.

I don't have enough time.

Inversion can be done by 'dominance'.

Quote:
+ dominance : (default : 0)
Which field, top or bottom, is displayed first.
- 0 : Obey source flags
- 1 : TFF i.e. Top -> Bottom
- 2 : BFF i.e. Bottom -> Top
This option is enabled only if 'repeat' is set to true.
Even if a source file is TFF, If the first frame consists of two PAFF field coded pictures and the first field is missing, it should be treated as BFF.
Libavcodec returns frames by pair of two field coded picture.
You can see the source is TFF but the recorded and decoded stream is BFF.

source: ... T0 B1 T2 B3 T4 B5 T6 B7 T8 B9 ...
recorded: B1 T2 B3 T4 B5 T6 B7 T8 B9 ... (the first field dropped)
decoded: [B1 T2] [B3 T4] [B5 T6] [B7 T8] [B9 X] ...

For PAFF field coded pictures, there is no concept of field order or field dominance.
They only play role being coded as top field or bottom field.

I'm not a C++ programmer.
Though LSMASHSource is written in C++, most features of C++ is not used :P
And the part of shared codes between AviSynth, VapurSynth and AviUtl is compilable with both C99 and C++.
So, basically it requires knowledge about only C.
