L-SMASH Source

[Dogway]

I know FFMS2 can't but does LSMASH support image batch loading? something like IMG_%04d.JPG?

The only image loader that I know that does this is ImageSource, but that one converts the images to RGB internally.

You can try ImageSequence
http://avisynth.nl/index.php/ImageSequence

[Dogway]

CoronaSequence outputs RGB, I tried RawSequence() but it gives an error:

Error requesting frame 0
Cache: Filter returned invalid response to
CACHE_GETCHILD_AUDIO_MODE.10

Anyway, for today I solved it using batch scripts, but would be good to have a nice image sequence loader for next times.

You can try JpegSource too

[Dogway]

JpegSource can load image sequences? Anyway it's an outdated (x86) closed source plugin, it's the best jpeg decoder quality wise but no help there.

To answer this original question, yes it does (at least on Linux, but as filename handling should be internal to the plugin, I would assume that's also true on Windows).

I output a sequence of PNG files as well as a sequence of JPGs, and LwLibavVideoSource was totally cool opening the entire sequence using:

LwLibavVideoSource("output_%02d.jpg") # or output_%02d.png

The PNG sequence remained bgr24, the JPG sequence remained yuv420p.

at least on Linux

On W10 [EDIT: x64],

create_RGB.avs

# Export "Image Sequence" to ".\PIC_RGB" existing directory via VDUB2,  png with basename="RGBIMAGE_" and 6 digits
Colorbars(Pixel_Type="RGB24")
ShowFrameNumber
Trim(0,-100)

RgbIn.avs

LwLibavVideoSource(".\PIC_RGB\RGBIMAGE_%06d.png")    # "PIC_RGB" directory within the current directory.

Works OK,

###########

create_YUV.avs

# Export "Image Sequence" to ".\PIC_YUV" existing directory via VDUB2,  jpeg  with basename="YUVIMAGE_" and 6 digits

Colorbars(Pixel_Type="YV12")
ShowFrameNumber
Trim(0,-100)

YuvIn.avs

LwLibavVideoSource(".\PIC_YUV\YUVIMAGE_%06d.jpg")    # "PIC_YUV" directory within the current directory.

Avisynth open failure.
[Fatal]: Failed to avformat_open_input.


EDIT: Oops, WORKS (returned as YV24, pre save source was YV12 [VDUB may have changed for save])
YuvIn.avs

LwLibavVideoSource(".\PIC_YUV\YUVIMAGE_%06d.jpeg")    # VDub2 exported with 'jpeg' extension

It cannot. SEt had it on his todo list but never happened.

Nice tip, I had no idea LwLibavVideoSource was able to do that.

-------------

Another method of opening up image sequences is ImageSourceNV but requires an NVidia GPU and it converts YUV images to 4:4:4.

I am confused about drc_scale:

0.0 : DRC disabled. Produces full range audio.
# ok I understand this

0.0 < drc_scale <= 1.0 : DRC enabled. Applies a fraction of the stream DRC value. Audio reproduction is between full range and full compression.
# ok so 0.5 gives half compression, 1.0 gives full compression, understood

> 1.0 : DRC enabled. Applies drc_scale asymmetrically. Loud sounds are fully compressed. Soft sounds are enhanced.
# I thought 1.0 was already fully compressed?  What is meant by "asymmetrically"?

You can read this thread about DRC and see the attached image with the volume amplify/ attenuation values (the most common is Film Standard) applied to the audio.

With drc=0 the 'None' curve is applied, with drc=1 the showed curve is applied and with drc>1 a more agresive (plane) curve must be applied with all sounds at same volume.

Of course apply drc is only recommended at play time, never when you want recode or recover the original audio.

Very useful, thanks.

I can now try to emulate these in soxfilter as well - great!

Maybe like this?

Thanks for the Christmas present, asd-g!

That's the error I get for an image sequence of P1000054.JPG, P1000070.JPG, P1000074.JPG, etc.
Explicitly loading by the filename opens it but the sprint syntax calls that error. Tried with "P1000%03d.JPG", on Win11 x64.

Is that the right numbering ?

If "gap" / "gapless" isn't supported maybe you can request that feature

What should it return ? Black "placeholder" frames inbetween ? Or just the frames present ?

[StainlessS]

Tried with "P1000%03d.JPG", on Win11 x64.

Try "P1%06d.JPG" (or for Vdub2 output "P1%06d.JPEG")
EDIT: Maybe the literal "000" of "P1000%03d.JPG" is confusing the code, somehow.

EDIT: Also if prob try,
".\P1%06d.JPG" or ".\P1%06d.JPEG",
or full path in place of current directory relative ".\".

EDIT: OK, maybe I misunderstood, looks like PDR got it.

EDIT: LWLibavVideoSource seems not to have equivalent to ImageSource("...",end=100)

LWLibavVideoSource(string source, int stream_index = -1, int threads = 0, bool cache = true, string cachefile = source + ".lwi",
int seek_mode = 0, int seek_threshold = 10, bool dr = false, int fpsnum = 0, int fpsden = 1,
bool repeat = unspecified, int dominance = 0, string format = "", string decoder = "", int prefer_hw = 0,
int ff_loglevel = 0, string cachedir = "", string ff_options = "")

[Dogway]

Thanks StainlessS, tried P1%06d.JPG, no dice.

Frames present. These are the photos I selected from the set, and want to bulk filter them (resize, etc) with AVS+ tools.

I just tested renaming them to P1000000.JPG and P1000001.JPG and they load (both) fine. Also starting from P1000001, and so on. So the only problem it has is the numbering gaps. I can rename them to sequential temporally but could great to have this feature embedded.

Doggy, loads all files matching, "P1??????.JPG|JPEG" # "P1" + 6 characters (hopefully Digits) + "." + ("JPG" OR "JPEG")

Untested.

IN_FILES = "P1??????.JPG|JPEG"                           # "P1" + 6 characters (hopefully Digits) + "." + ("JPG" OR "JPEG")
OUT_FILE = "FILE.List"
result   = RT_WriteFileList(IN_FILES,OUT_FILE)          # Create a listing file of Pic filenames
Assert((result!=0), "No files found")
FILELIST = RT_ReadTxtFromFile(OUT_FILE)                 # Get list of files
#RT_FileDelete(OUT_FILE)                                # we are done with the temp file
NFILES   = RT_TxtQueryLines(FILELIST)                   # Query Number of lines in String ie number of files.
RT_Debug("Found files = " + String(NFILES))

C=0                                                     # Dummy clip
For(i=0,NFILES-1) {
    FN=RT_TxtGetLine(FILELIST,i)                        # Filename
    tmpC = ImageSource(FN,end=0)
#    tmpC = LwLibavVideoSource(FN)
    C = (C.IsInt) ? TmpC : C + TmpC                     # All clips must be same size.
}
C # EDIT: OOps, forgot this

EDITED: still untested.
