FFmpegSource

[Groucho2004]

Any idea what can cause absolutely insane frameskipping and thus desync with FFMS (both "live" and in final render)? AviSource works fine, but if I use FFMS to open recorded AVI it behaves weirdly slow and inconsistent (after the index build).
Post your (complete) script. Have you tried setting "threads" to 1?

[LigH]

Furthermore, it might be useful to have a MediaInfo analysis, to know which VfW codec was used to create the video stream inside the AVI.

AviSynth 2.6 release 32bit/ST, FFMS 2.21

Any idea what can cause absolutely insane frameskipping and thus desync with FFMS (both "live" and in final render)? AviSource works fine, but if I use FFMS to open recorded AVI it behaves weirdly slow and inconsistent (after the index build).
I see you had trouble with this format before, have you tried a recent ffms2 build from qyot27?

[Kein]

Was there anything relevant to my issue?

I don't know. It's almost always trial and error.
- Try a newer build
- Try "threads = 1"
- Try without the audio
- Upload a sample with which this can be reproduced

[real.finder]

Here's yet another test build (https://www.dropbox.com/s/eneprw5kfw7s5wk/ffms2-delaytest1.7z?dl=1). Let's call it kinda 2.22 rc2.

It should fix the weird video repeat at the start with delayed video. And some other issues related to it that were a lot less obvious.

[LigH]

Does AviSynth offer a YUV 4:1:1 mode at all? I would expect it to have been upsampled to an available format (e.g. YUY2 or YV16 in YUV 4:2:2) when color space conversions are supported.

[jpsdr]

Yes, 2.6 support it.

The RAW sample is to big to download.
The "AviSource" is AVC wrapped in a .mp4 file
I can't guess what "FFMPEG Source" means.
So, I have no idea what any of these samples represent.

In order to reproduce something you have to provide the a sample of the source (ideally much smaller than 3GB) and the exact steps to reproduce the problem.

[LigH]

2. non-MT version

It doesn't matter if AviSynth is an MT version; some plugins fork threads on their own. For FFMS2, it can be necessary to limit this plugin specifically to only 1 decoder thread: If FFMS2 can handle an input file well, multiple decoder threads can speed up the decoding remarkably; but if FFMS2 may have issues with a format, multiple decoder threads make it even worse, and it gets completely confused.

All unable to find suitable output format errors should now be fixed in git (at least the ones for formats new to avisynth 2.6). I simply forgot to add the last few lines of code needed.

I'm not sure what so hard to understand:
AviSource is the sample encoded through AVS AviSource into AVC/MP4
FFMPEG Source is the sample encoded through AVS FFVideoSource/AudioSource/Dub into AVC/MP4 with the same (1:1) settings.

In order to reproduce something you have to provide the a sample of the source (ideally much smaller than 3GB) and the exact steps to reproduce the problem.
So, I did provide you a sample of the source, 2.4Gb (which is less than your suggested 3Gb) and you complained how big it is?
Are you replying to me for the sake of replying? I mean, I have a feeling you just keep up hollow discussion, why just not ignore my question then.

Not everyone has VDSL (and on top, many free file hosters throttle downloads to annoying speeds). Often it is still a pain and possibly a waste to download Gigabytes, especially if the effect may possibly appear with much smaller samples as well.

The FourCC "xtor" points at the DirectX capturing software DXtory; recording high resolutions without compression can be quite demanding for the harddisk, so I guess the reason might be dropped frames not being handled as well by FFMS2 as by AviSource.

I have much better things to do than wasting time on discussions with a low signal to noise ratio and I just have lost interest in this one.

Hi,

I have a found a couple of samples that will encode correctly with FFMS2 v2.21 (also tested with v2.20 and v2.19) but fails with FFMS2 v2.22RC2. I'm using MeGUI and the samples do go through the indexing step but fail when it starts to encode. It seems to be related to them being MPEG2 (bluray rip via makemkv).

http://s24.postimg.org/ibjkaudat/Me_GUI_FFMS2.png

This is the error that MeGUI is showing when I try and encode with v2.22RC2

Hmm, didn't think of that, altho, my HDD goes for 66-72MB/s so it should suffice in linear read for conversion.

[LigH]

Linear reading is not the problem; but what about writing during the recording, when Windows just even decides it must access the swap file urgently because the game being recorded allocates more RAM?

Writing being done on another physical HDD. Swap is there too and it just 64Mb - I have 16Gb RAM and never hit limit during encoding.

-RC3 still has issues loading Prores files which worked before in 2.21 (stopped working from 'rc2', -delaytest). Kinda hoped the color-formats would have fixed it.

Zzzzzzzzzzz...This one doesn't work for me with my FFV1 files. It causes an access violation in Avisynth.dll when opening the video with FFVideoSource. Version 2.21 doesn't have this issue.

Here's a sample file: https://drive.google.com/file/d/0BzeF_1syecQwX0w0UDZ1S2JkQ0U/view?usp=sharing

I'm confused - which is the recommended version to use that doesn't have the "off by one frame issue"?

[qyot27]

Even though I initially doubted it, it would appear the FFV1 issue (and it's not only FFV1; ffvhuff is also affected, at least) occurs due to colorspace issues.

I generated a test sequence with FFV1 using FFmpeg:
ffmpeg -f lavfi -i testsrc -vcodec ffv1 -t 10 test.avi
This video file caused the crash with FFMS2 (I'm testing the C plugin here, so chances are pretty high it's not in the plugin wrapper). By default, the testsrc outputs RGB.

However, if I force FFmpeg to write the file as 4:4:4,
ffmpeg -f lavfi -i testsrc -vcodec ffv1 -pix_fmt yuv444p -t 10 test.avi
It no longer crashes.

The results:
YV12/yuv420p = crash
YUY2/yuyv422 = [FFV1 doesn't support YUY2, it gets converted to standard 4:2:2, see below]
RGB24/bgr0 = crash
RGB32/bgra = works
YV16/yuv422p = works
YV24/yuv444p = works

Obviously this is a problem, since 4:2:0 and RGB24 are arguably the two most commonly-used pixfmts.

Furthermore, AvxSynth doesn't exhibit this behavior, even if avxffms2 is built with the updated sources. It lacks support for the 2.6 pixfmts, though. That's part of what made me start thinking it was pixfmt-related. The weird thing is that the last public build of the C-plugin (from June 25th) didn't exhibit this problem, and there haven't been any specific pixel format commits since.

Ut Video also exhibited the issue with RGB, and in that case, opening it with AVISource worked, while FFMS2 threw the same Access Violation shown above. It's not possible to test AVISource with FFV1 and ffvhuff because of ffdshow being horrifically outdated.

[Selur]

btw. what is the latest FFMS2 c-plugin version?

[qyot27]

FFMS2 C-plugin r1072+90

This isn't the newest build, as it's from August 25th or thereabouts, but it's the most recent one that works. My latest test builds are crashing (not related to the stuff above, since it's doing it on every file) and I need to figure out why.

This build does not support AviSynth 2.5.

EDIT 2016-02-25: Newer build available here. (http://forum.doom9.org/showthread.php?p=1758567#post1758567)

Thanks for clearing that up and sharing that build. :)

Small update on the issue I reported before:

This is interesting, if i use FFMS to open and join two files through Dissolve:
a=FFAudioSource("1.avi")
b=FFVideoSource("1.avi")
c=AudioDub(b, a)

d=FFAudioSource("2.avi")
e=FFVideoSource("2.avi")
f=AudioDub(e, d)
Dissolve(a,f,60)

the final result will have desynced audio right when second clip start (firs one is fine). Same happens if I use AlignedSpace().

However, if I use UnalignedSpace() there is no audio-to-video sync issues. Odd. Exactly vice versa with AviSource (i.e. it works as intended).


Hmm, is there a Dissolve() analogue with UnalignedSpace() method?

Also, is there any other plugin a-la FFMS that allows you to load clips in its native colorspace without forcefully converting it like AviSource into RGB?

[LigH]

*Splice instead of *Space

AviSource does not "forcefully convert to RGB". Usually it asks the VfW codec which decoded formats it offers and which will match best a list of supported formats (e.g. DivX will usually be loaded as YV12). You may tell AviSource to request a target 'pixel_format', but when the VfW codec can't output this, AviSource would fail instead of accepting the next similar. — Maybe your DXTory VfW decoder was set up to "always output RGB", or simply returns RGB because it had recorded and saved RGB? I don't know if it is at all able to save YUV.

UnalignedSplice will match the video streams and the audio streams of both clips independently. If the video stream (a) and the audio stream (b) of the first clip (c) had a different length, this will usually introduce a skew from the joint on. But if the second clip contains audio with the same amount of skew (may happen when they were one continuous movie before and cut into segments), then the skewed audio will match again, like a "tongue and groove" joint. AlignedSplice (and Dissolve) instead will make video and audio streams match and fill up gaps; furthermore, loading d and e separately and dubbing them without checking for a possible audio skew and using DelayAudio(ms) will probably already have created an asynchronous clip f in this case.

pixel_format NEVER worked for me regardless of source material and codec used.

As for DXTory format - this time I used FRAPS, not DXtory.

Hmm, not related to the subj but how can I check for skew?

[LigH]

VirtualDub (File Information); MediaInfo; GSpot ... at least one of them should probably be able to display a skew (delay) for the audio stream relative to the video stream.

No "skew" there, video and audio streams have the same exact length.

Is avresample (or swresample) now mandatory to build ffms2 ? I've tried to build without any of them, and build failed. It wasn't the case before, so i'm wondering if there is any change ?

[Jamaika]

I would like to ask how to properly give a title and language tracks in muxer ffmpeg(20150927) for container MOV. I can't cope.
ffmpeg.exe -i input_pol.srt ... -f mov -map 2:0 -metadata:s:2 language=pol -metadata:s:2 title/{changed to "handler"}="Subtitle (pol)" -sub_charenc UTF-8 -c:s mov_text ...
The result in MediaInfo 0.7.7:
Tekst
ID : 3
Format : Timed Text
Codec ID : text
Duration : 2 min.
Bit rate mode : Zmienna
Bit rate : 10 b/s
Stream size : 149 bajtów (0%)
Language : 25
Title{lack} : {lack}

Edit: OK, I found even a partial answer.

Although, already solved, that's an entirely different "ffmpeg". A binary encoder unrelated to Avisynth (directly unrelated; indirectly it can be useful).

now work with yv411 but with upside down green image

still in 2.22 too

sample http://samaup.com/a7o3lluxx2m6

[real.finder]

is this ok? https://www.virustotal.com/en/file/678f0a3003f26f7daf7dac33d8af10241e53fefdb446cb8cae1e36c739cb757d/analysis/ from this https://github.com/FFMS/ffms2/releases/tag/2.22

[jpsdr]

Maybe there is a minor cosmetic display issue in the configure file, because my output is :

checking for AVRESAMPLE... no
checking for AVRESAMPLE... yes

Isn't the second not AVRESAMPLE but SWRESAMPLE ? Because i've not enabled AVRESAMPLE, but SWRESAMPLE wasn't disabled when i've build ffmpeg.

[szabi]

Hi

I downloaded ffms2-2.22-msvc (https://github.com/FFMS/ffms2/releases).
But I can not use it because:
http://abload.de/img/ffms2222-msvcxtp5b.png

Previous version does not have this issue.
Is there a solution?

bye
