Hmm, I don't think they are artifacts. The video source is a still image under 185mbps bitrate... it should be virtually lossless. Image taken with old build have straight lines which Is expected. Bot on another screenshow... I never seen such artifacts, pattern looks too perfect to me and doesn't even reminds any kind of macroblocks.
It will be nice to hear someone else's opinion on this.

Just compiled a build against latest ffmbc (0.7rc7), seems it decodes without problem but I didn't check whether the bug is fixed. Anyone interested to try it?

I will check it.

update: it works fine- great work

So now- does ffms2 has to index all files, even those with I frames only- like ProRes, uncompressed?
Indexing is bit slow- I have 0.5% CPU usage.
Some QT reference files are also not working same way as in QT player.

Yes, ffms2 need index for all files. Indexing speed mainly depends on your disk speed (or network speed if your file is on a network drive).

You can check transfer speed using performance monitor (assuming you are using win7). If indexing uses more than half available bandwidth then I think it is normal.

How are they different?

PS: The previous version can't read color matrix flag from source file, I just compiled a build that fixed that.

Sorry- indexing is fine, I'm just not patient enough

It reads at about 100MB/sec. Gigabit on Win7 works at full speed- not at 50% like it use to be on XP.
One thing- in some cases info jumps from 0 to 99% straight away, but sometimes it works fine. These are all I frame only files- ProRes, DNxHD, uncompressed.
It took about 6 minutes to do 130GB ProRes on my local RAID, so it's ok.

Files, which I refer to are reference files to AVID MXF files (reference files are created by 3rd party software CalibratedQ). I noticed that nothing based on ffmpeg can open them- ffmpeg, ffmbc etc. They do work fine in QT player.
Thanks for the new build- reading ProRes, DNxHD was fine anyway (at least for my samples), but good to have it working as it should.

Thanks.

But I think we need to mention that ffms in the first post is linked with libav, and the second one is linked with ffmbc. The first version may be better for general video files, but have bug on decoding DNxHD files. The second one fixed the bug, and may have better support for professional video formats.

jmac698 · 2nd August 2012, 04:07

Um... could you go there, click edit, and make the changes? It's not hard

Oh sorry, previously I thought that it needs special privilege to edit the wiki. Just made some modification to it.

jmac698 · 2nd August 2012, 07:59

Thanks.
I made a small correction, but really I should have told you first and let you do it. You can check if you agree.

SAPikachu · 2nd August 2012, 08:05

That's OK, it was just my typo (and bad grammar :P ). The paragraph is clearer now, thanks.

I have a problem loading the patched ffms2.dll.

I'm using Avisynth 2.60 and Virtualdub 1.10.3 (32bit). I have ffms2.dll, ffmsindex.exe and FFMS2.avsi in my Avisynth plugins folder. Opening my avs file in Virtualdub gives the following error:

Quote:

Avisynth open failure:
LoadPlugin: unable to load "C:\Program Files\AviSynth 2.5\plugins\ffms2.dll", error=0x7f

However, using an unpatched ffms2.dll and ffmsindex.exe works. There is a delay while indexing then the video opens.

I've tried both versions: ffmbc and libav. I used LoadCPlugin for ffmbc which I believe is correct. I admit I lean towards the newbie side.

Any ideas?
Many thanks.

Sorry I mistakenly broke XP compatibility of my last build. Are you using Windows XP? If so, you can try my latest build.

fleebitten · 18th January 2013, 20:30

Hello SAPikachu, yes I'm using XP. I'll give this one a try, thanks very much.

fleebitten · 19th January 2013, 11:38

Just to confirm that this worked okay, thank you.

Does this version support 4:2:2 like the previous one you posted?
Many thanks.

Yes, hacks are the same as ones in previous versions.

fleebitten · 19th January 2013, 16:43

That's great, thanks.

I would just like to check that everything is okay as I'm not sure exactly what the LSB part should look like. I'm opening a 10bit 4:2:2 v210 clip. Viewing in Virtualdub shows green for the LSB part with just the brightest highlights that are in the video coming through (white only). In other words, just the very highest luma values. Is this how it should be?

For 10bit videos there aren't much data in LSB part, so as long as LSB part is not all green, it should be normal.

fleebitten · 21st January 2013, 22:40

Thanks again SAPikachu.

I've a problem with f3kdb_dither though. My source video is v210 4:2:2 10bit as mentioned. With the following code:

Code:

FFVideoSource("test.avi", enable10bithack = true)
f3kdb_dither(input_depth = 10)

I get a lot of noise and no picture to speak of. Not until I set input_depth to 16 do I get a normal picture.

Any ideas why that is?
Thanks for any help.

kolak · 21st January 2013, 23:06

Maybe because hacked ffms2 reads 10bit as 8bit+8bit, so input should be 16bit. Avisynth does not support "real" 10bit formats.
