v210 codec

[jmac698]

I found a v210 codec for directshow
http://www.drastictech.com/download_codec.html
still can't open with directshowsource though :(

Also Blackmagic design codec, cineform hd codec, aja Kona codec.

ffmpeg didn't list v210 in -pixfmt list
ffdshow doesn't list it.
libquicktime does it, if there's anything compiled that uses it...

http://gmerlin.sourceforge.net/ Although last time I tried it I'm sure it clipped.

Might help, based on libquicktime I think, Cinellera possibly, ffmpeg only decodes v210 not encodes. Drastics are available in Virtualdub.

Where is 0.2 available? Cheers

[jmac698]

I tried opening a .mov in virtualdub, no go of course. So I have to convert somehow to .avi, this gmerlin could be the only way.
All I've found is kona 4.2.1, blackmagic design 7.9, cineform 3.2.2.185, dtcodecs3.0.0. ffmbc looks promising too.

ffmpeg definitely encodes v210 , it has been working for at least a few months

it only decodes r10k (10-bit RGB)

I've been using autobuilds

Ok good to know, my bad when I think v210 I immediately think 10bit.

v210 is 10-bit Y'CbCr 4:2:2

r10k is 10-bit RGB 4:4:4

Of course, this indicates nothing about how it was derived. I'm not sure what ffmpeg does with a 8-bit Y'CbCr source for example. Does it pad to 10-bits ?

But I still can't open with ffmpegsource or directshowsource....

What can't you open ?

ffvideosource() will open v210 in mov or avi , but it will become 8-bit afaik

if you have drastic codecs installed, avisource() will open v210 in avi

I'm not sure how your code works, but as soon as anything is opened with avisynth , it's no longer 10-bit. This applies to prores as well using qtinput()

[jmac698]

yay! ffvideosource worked. That's awesome, I really need to know PICTTYPE for another project. And I wonder if the auto contrast filter will scale 10bit?
Thanks

ps qtinput is the only one with dither option, which I was able to use to extract 9bits of the file. ie, round(2.5)=3, trunc(2.5)=2, lastbit=round-trunc, highbits=trunc.

qtsource.dll will help you

it'll open v210 in mov or avi (as quicktime can load avi files that it has codecs for).

even without the blackmagic/kona/bluefish/anyothercapturecard drivers, you'll be able to load it. it'll either be truncated or rounded to 8 bit (no dither - the rounding is a stub for a future dither).

it'll be faster than waiting for ffvideosource to index, and decoding speed would be very similar (i haven't tested), possibly faster as qtinput uses it's own internal decoder rather than relying on quicktime's shitty one.

I have a related question, how to play such files realtime? VLC just shows a blackframe. In mediaplayer, a strange thing happened,
[quote]The requested lookup key was not found in any active activation context". Is this DRM? Why should I get that on this file?

[poisondeathray]

that's weird , which file were you trying to play?

kmplayer should be able to play them, and quicktime player as well (but I think quicktime will depend on installed codecs)

A warning about drastictech by me (just had this happening here):

Do you know where can I download Blackmagic Quicktime codecs? I'm want to open v210 in Quicktime Player. I have AJA Kona Quicktime codec but is having some problems.

Usually the codecs come with the Blackmagic universal driver packed into the all-in-one-Installer "Desktop Video"
https://www.blackmagicdesign.com/support/family/capture-and-playback.
It is huge and from time to time something within a version is borked, so please don't throw stones at me if something doesn't work out as expected...
Read up on their forums ! (Blackmagic user here)
