Avisynth/FFMS2 error: video track is unseekable

[marcorocchini]

Hi

when I try lo load in avisynth file .mxf larger than about 2 Gb avisynth get "video track is unseekable"

is there a way to resolve?

thanks

[ndjamena]

Grrrr! A 31 bit limit!

[ndjamena]

Try FFVideoSource instead.

-Edit- I thought I told you to use DirectShowSource but apparently you didn't. And what's with this putting info in the Thread Name and not the actual thread business? It's confusing, you look at the thread name to see if it looks interesting or not.

[marcorocchini]

.. or rather?

[marcorocchini]

FFVideoSource("i:\unseekable\26.mxf")


= Video track is unseekable

[ndjamena]

So, you've tried both FFVideoSource AND DirectShowSource then.

It would seem to be caused by something using a signed 32 bit integer somewhere, if neither of those work then you'll have to try cutting.

[marcorocchini]

possibly I don't want use directshowsource... hoewver directshowsource works well

[poisondeathray]

You can try 64bit avisynth, 64bit FFMS2 , but but I doubt that is the problem, you can load larger than 2GB files with 32bit FFMS2

Or try different FFMS2 builds , or L-SmashSource

64-bit versions of programs just use 64-bit memory pointers, they'll still use 32 bit integers if told to.

-Edit- Some minor tweaking may be involved ie VirtualDub name/command line (this command line is for the current mainstream Virtualdub), contents of .vcr file etc...

-Edit2- There's a bug in my recursion code, it's supposed to stop at the first level it finds a video file, but it forgets after each directory. I haven't got round to fixing it yet.

[marcorocchini]

I have try to clean the avisynth dir, fresh install of avisynth and install of a clean ffms2 (R275) plugin:

now virtualdub open also large files but strangely need of several minutes to load. Seems hard disk C: work a lot as soon as a file copy by avisynth

If I use directshowsource the time to load is 1-2 seconds

maybe avisynth do an operation or a copy?

[ndjamena]

*sigh* FFVideo Indexes the file first. It helps with seeking, which you're not interested in.

[marcorocchini]

errata corrige: ffms2_2013-01-13_git-f081983_libav_git-ea81bb2.7z is the one I have try, not the R275

hoewver to load in VDM a video file of 2GB employ 2 minutes... seem too. Virtualdub with the FFinputDriverPlugin emplys 1 second

seems avisynth do a file copy into C: or internal buffering

[ndjamena]

How have you discovered this? FFMPEG only needs to index the file once, it creates an index file for it in the same directory as the video file, any further calls to that video file will use that same index file so there's no need to index it again.

[marcorocchini]

my .avs is:

FFVideoSource("i:\EXunseekable\26.mxf")

and i: is a separate hard disk

avisynth is on C:

Once 26.mxf if I try reload 26.mxf, loading is immediate
but if I trt lo load another larger file, e.g. my 12.mxf it employs 2 minutes
but if I reload 12.mxf, loading is immediate
but if I load from new 26.mxf it employs 2 minutes
... if I reload 26.mxf is immediate...

[ndjamena]

I hope you're agreeing with me there. You could try pre-indexing them with ffmsindex.exe first if you're worried about it.

[marcorocchini]

I have installed avisynth 2.5.8 wi this ffms2 plugin:



semms it don't have ffmsindex.exe, or don't need it however my proof is:

DirectShowSource ("26.mxf") = immediate opening in VDM
FFVideoSource("26.mxf") = 1-2 minutes to opening in VDM

if if there a way to immediate opening, maybe pre indexing, whit the ffms2 plugin would be a good idea

[ndjamena]

ffmsindex.exe isn't a plugin, it's a program, you'll probably find it in your plugins folder, assuming that's where you put it. Just drag and drop anything you want indexed onto it and it will make an index for you. I could try to add look ahead to the batch so it can index future files while VirtualDub works on the current one if you like.

[marcorocchini]

I don't have well understand: you says is there a way to open .mxf file directly in VirtualDubMOD without avisynth?

I'm forced to virtualdubmod because otherwise I cannot have timecode...

[marcorocchini]

for the moment my batch was this: but I have to change for use with virtualdubmod.exe and I have to build a batch that consider the input select .mxf file (%d%\%%~na.mxf) and have to generate a script of avisynth that assume %d%\%%~na.mxf as source

... FFvideosource("%d%\%%~na.mxf")

after this virtualdubmod.exe have to eat what avisynth have to get, but inserting the timecode

I try to use you batch to adapt my batch to do it .. if I'm able

I never said anything like that. I'd never say anything like that because I've never tried to open anything in VirtualDub with anything other than AVISynth. I think you must be talking to someone else.

[marcorocchini]

oh I'm a cat, I don't speack well english

my batch choose the older .mxf file of a specify directory and discern from HD to SD

If is a .mxf HD do ...

If is a .mxf SD do ...

but now I cannot use moreover virtualdub. I'm forced to virtualdubmod because there is no possibilities to batch-automate the procedure of insertion the timecode.

[marcorocchini]

ndjamena please in your batch what is the part that create an .avs file that contatin the source %input%.mxf?

[ndjamena]

If you click on 'Go Advanced' there's a 'Code' Box [#] that will let you insert your script with all the tab characters I hope you use. It really would make it easier to read.

[ndjamena]

echo DirectShowSource^(%4^)>%2

In it's entirety.

you refer to virtualdubmod?

[ndjamena]

I'm referring to the forum. Bottom right ->>>

[marcorocchini]

virtualdub have vdub.exe that can do:

vdub.exe /max %d%\%%~na.mxf /s scriptHD.vcf

but now I have virtualdubmod.exe that don't have any vdub.exe

I'm try to understand if is there a way to launch virtualdubmod.exe with a specific script

[marcorocchini]

https://forum.videohelp.com/threads/364467-VirtualDubMOD-launch-and-script-problem

nice

[marcorocchini]

ndjamena sorry, I try to adapt your script with mine

I use this .mxf

https://dl.dropboxusercontent.com/u/39871584/C0020.mxf

in a dir where I have VirtualDubMod 1.6.0.0 Surround and ffprobe.exe

- for the moment not consider my script -

to adapt your at the c0020.mxf I think the major question is adapt at the line

"VirtualDubMod.exe" /s"F:\Script.vcf" /p"F:\Video.avs","F:\Video.avi" /r /x

to "VirtualDub.exe" /s %1 /p %2 %3 /r /x

so to do that is necessary the script creare a phisical .vcf file (e.g. script.vcf) so virtualdubmod have script.vcd ready? otherwise I can no use your script

[ndjamena]

"VirtualDub.exe" /s %1 /p %2 %3 /r /x

==

"VirtualDubMod.exe" /s%1 /p%2,%3 /r /x

Everything after :MAKEVCF makes the vcf file, the avs file then calls VirtualDub[Mod]. Like I said, you may have to alter the vcf lines to suit.
