Using MVTools with a linear access only script

[FranceBB]

Here's the thing: unfortunately I'm hog-tied to linear access seeking which means that I can't request frames to the indexer in a non linear fashion, but I need to use MVTools.
In this case, I kinda need to use

super = MSuper(pel=2, sharp=1)
bv1 = MAnalyse(super, isb = true, delta = 1, overlap=4)
fv1 = MAnalyse(super, isb = false, delta = 1, overlap=4)
bv2 = MAnalyse(super, isb = true, delta = 2, overlap=4)
fv2 = MAnalyse(super, isb = false, delta = 2, overlap=4)
MDegrain2(super,bv1,fv1,bv2,fv2,thSADC=200, thSAD=200)

but of course when I use it, it prompts me to a non linear access (non linear seeking). Is there a way to use MDegrain with vector calculations in a way that doesn't require non linear access? I really need it in an automated workflow which is strictly required to use linear access... :(

As always, thank you in andvance,
Frank

However, if you uncomment Prefetch(4),
it puts up an error message on frame, that RT_DebugF has an unexpected data arg 3,
it interprets the Name="FranceBB: " as a data arg to RT_DebugF, instead of a named optional argument, named "name", [ie name="FranceBB: "]
I tried with v3.5.1 and v3.6.2 test 1, both same, I think is Avs+ problem.

Produces this and no error, however looks like AVS+ does indeed have a problem somewhere (where optional named arg and Prefetch, EDIT: where named arg follows data arg array)

EDIT: Maybe RequestLinear() also plays a part in the problem, as it worked OK prior to adding it to the script.
EDIT: No it was a problem before Request Linear, dont know how I got Prefetch(4) debug output, it should have broken it.

Above posted problem with AVS+ v3.6.2, disappears with v3.6.2 test 2

did you tried with test 2 ? https://drive.google.com/file/d/1h-CyjQPEvmj6ZZgYbYUY1pgrp8eovr9w/view

so this should work ok with/without Prefetch() [and with/without the Scriptclip part which just verifies linearity]


AviSource("D:\parade.avi").trim(1000,-50)

Global G_PreviousFrame = n

decoding your input to an uncompressed bitstream and read the bitstream using rawsource

[StainlessS]

RawSourcePlus stuff:- http://avisynth.nl/index.php/RawSource26

[FranceBB]

Thank you, StainlessS, I'm trying right now and it seems to be working. ;)
@feisty2 well as long as it works with RequestLinear() and I don't have to make an uncompressed stream I'm gonna be fine. ;)

[StainlessS]

FBB,
how did you make rawsource fle, I tried this, shows codec not supported

EDIT: Above, added in blue, now it works, well dont gove error.

Needs some additonal parameters, if you can fit them in to batch file then could be automatic.

EDIT: Also, is rawvideo, video only ie no audio ? [presumably yes]

EDIT: Change to below, same.

%FFMPEG% -i "%INDIR%\%%A" -vcodec rawvideo -an "%OUTDIR%\%%~nxA.rawvideo"


EDIT: Seems need something like this, so I guess non automatic

-pix_fmt rgb24 -vtag 0x20776172


EDIT: Added -f rawvideo to above batch file, seems to work [at least no error].

[StainlessS]

Using above posted demo batch file [with added -f rawvideo],
outputs the y4m, [EDIT: Changed y4m to 'rawvideo']

and this output the video ok, can omit pixel_type, just needs both width and height [even guesses 25 FPS ok somehow].

RawSourcePlus(".\big_buck_bunny_720p_h264.mov.rawvideo",width=1280,height=720) # EDIT: Changed extension to rawvideo
return last.info


https://i.postimg.cc/y3sbL1t4/FBB-00.jpg (https://postimg.cc/y3sbL1t4)

EDIT: Demo cmd may not work proper if non YV12 source, probably defaults to YV12 source.
RawSourcePlus() default is 25.0 FPS, so that explains correct fps, but default pixel_type is supposed to be "YUY2", but guesses "YV12" correctly.

EDIT: Apparenlty y4m format has a rudimentary header so is not raw, changed cmd file output extension to rawvideo.

%FFMPEG% -i "%INDIR%\%%A" -vcodec rawvideo -f rawvideo -s 1280x720 -an "%OUTDIR%\%%~nxA.rawvideo"
