Matroska support

[DaveQB]

my searching seems to show theres no filter (or anything of the sort) to open .MKV files with AVISynth

am i right ??

[Wilbert]

Yes, you are right.

[Kika]

DirectShowSource should be able to open a MKV-Video.

[DaveQB]

hmmm tried that before, thought i had no success.

tried now, VDMod hangs

TCMP returns

[Wilbert]

What's your script?

[Kika]

@ DaveQB

I tried it right now: sucess!
Maybe your file has errors?

Oh, i don't know your Script, but this looks like an Error with the Color-Space.

[DaveQB]

hmm, the file plays fine without AVSynth,
in TCMP its all normal.

Parsing to VDMod takes forever, and then doesnt finish (Program just finishes)

file is 32gig's


#ASYNTHER Football
LoadPlugin("C:\program Files\aviSynth 2.5\plugins\mpeg2dec.dll")
LoadPlugin("C:\program Files\aviSynth 2.5\plugins\msharpen.dll")
DirectShowSource("R:\Raiders.mkv")
SmartDeinterlace(1,10,true,true,true)
msharpen(highq=true,threshold=25,strength=100,debug=false,mask=false

)
BilinearResize(512,384)


been using the exact same scripts on AVI's without a hitch

idea's ?
thanx guys

[DaveQB]

Success.
but only with a simple script

DirectShowSource("R:\Raiders.mkv")

so with that, does AVISynth have support for .MKV

or not ??

i'll try VDMod filters rather then AVISynth's ones, see if i get the same error

thanx

[Kika]

Do it step by step:

DirectShowSource("R:\Raiders.mkv", fps=25)

(fps=25 is for PAL, i don't know the right Framerate for your Video).

Try to open the AVS with MediaPlayer (mplayer2.exe!).

[Wilbert]

I'm also trying it. Opening a script containing mkv with AC3 in WMP6.4 went fine. I will try reencoding later this evening:

@DaveQB,

Could you try the following

DirectShowSource("R:\Raiders.mkv").info

I guess this should be YV12?

DirectShowSource("R:\Raiders.mkv")
SmartDeinterlace(1,10,true,true,true).info

I guess this doesn't work, because SmartDeinterlace needs RGB32 or YUY2?

DirectShowSource("R:\Raiders.mkv")
ConvertToRGB32
SmartDeinterlace(1,10,true,true,true)

should work ...

[DaveQB]

o, i deleted that file and recaptured in AVI again and got that encoding (got heaps to do, as fast as possbile)

but made a quick cap in MKV to run this

from that i get this

DirectShowSource("R:\Raiders.mkv")
SmartDeinterlace(1,10,true,true,true).info



ok this returns this

DirectShowSource("R:\Raiders.mkv")
ConvertToRGB32
SmartDeinterlace(1,10,true,true,true)



this returns the exact same as above




should work ...


weird ??!?!


thanx guys

[Wilbert]

DirectShowSource("R:\Raiders.mkv")
ConvertToYUY2(interlaced=true)
SmartDeinterlace(1,10,true,true,true)

works ?

[DaveQB]

yep i think ya got it,

i'll try encoding from the script now.

why, in a non-technical explanation, does adding "ConvertToYUY2(interlaced=true)" makes a difference?

without that line "info" reports RGB32 (i did capture it in YUY2 ?!?)


thanx for that, i guess AVISynth does, in a way, support .MKV

thanx

[DaveQB]

hmm it appears performance while encoding .MKV through AVS is slower then encoding .AVI through AVS
:(

shame

fix typo

[Wilbert]

The MKV is apperently RGB32 (your first picture). SmartDeinterlace requires YUY2, so you have to convert to YUY2 before applying SmartDeinterlace. This interlaced=true flag is used because your MKV is interlaced.

So, did it work? Could you convert MKV to anything else through AviSynth ?

i thought Smart Deinterlace supports YUY@ and RGB32.
i guess iw as wrong.

i captured in Virtual VCR-Matroska in YUY2,
so this means Matroska doesnt support anything but RGB32, or just the way its implemented into V-VCR-Matroska ??

yes it works, but encoding is slow.

you mean any other colour space ??

havent tried

[DaveQB]

ok this script work

LoadPlugin("C:\program Files\aviSynth 2.5\plugins\mpeg2dec.dll")
LoadPlugin("C:\program Files\aviSynth 2.5\plugins\msharpen.dll")
DirectShowSource("E:\2002 Season\DivX\raiders.mkv")
ConvertToYUY2(interlaced=true)
SmartDeinterlace(1,10,true,true,true)
msharpen(highq=true,threshold=25,strength=100,debug=false,mask=false)
BilinearResize(512,384)


but when encoding with VDMod 1.5.4.1 it cant finish an encode.

By that i mean it gets to 5 sec before the estimated time of finishing and then the estimated time of finishing counts forward each second in time with the current time so that theres always 5 seconds remianing,
this carries on 2 hrs after the time its supose to finish, both estimated time and the time i would of expected it to.

like an infinite loop

doesnt of course, happen with AVI files

is it Matroska or DisrectShowsource ??

NB: i am not sure why i still have mpeg2dec.dll
i dont need that for DirectshowSource do i ?? must be left over from something else i was trying, or maybe its for SmartDeinterlace, confused myself here

[Wilbert]

Probably DirectShowSource. Does that also happen if the mkv doesn't contain audio/subtitles ?

[DaveQB]

umm yes,

well i never use any sort of subtitles, wouldnt have a clue there
the audio, well i disable it in the first pass (obviously) and this is when this occurs

Maybe lack of audio ? :D
i think not

edit: do u mean the source?

[Wilbert]

edit: do u mean the source?
Yes. The audio support is still experimental, so that could be the problem. What kind of audio is it?

[DaveQB]

sorry, didnt know this had a reply must of missed the email

the source is HuffyUV and Audio is raw PCM 16-bit Stereo.

i have gone back to using AVI ( :rolleyes: ) for now.

i like what Matroska offers and i like the stability in capturing to a .MKV container, but post processing is a b%^&h!

also, unable to delete MKV files unless i restart the PC is a pain.

hopefully the next release will be that little better :)
